86-593: The Pastoral Greenhouse Gas Research Consortium (PGGRC) carries out research to find methods of reducing greenhouse gas emissions from livestock. The consortium, established in 2004, has a Memorandum of Understanding with the New Zealand Government . Almost half of the greenhouse gas emissions in New Zealand are due to agriculture and since the New Zealand government has signed and ratified

172-423: A "supply chain". At the end of the supply chain, materials and finished products only flow there because of the customer behaviour at the end of the chain; academics Alan Harrison and Janet Godsell argue that "supply chain processes should be coordinated in order to focus on end customer buying behaviour", and look for "customer responsiveness" as an indicator confirming that materials are able to flow "through

258-588: A bank, for example, may play a supporting role in certain supply chains, but acts as either the customer or the nearest supplier to the customer in the supply chain for security printing . Brown et al. refer to supply chains as either "loosely coupled" or "tightly coupled": Cutting-edge companies are swapping their tightly coupled processes for loosely coupled ones, making themselves not only more flexible but also more profitable . These ideas refer to two polar models of collaboration: tightly coupled, or "hard-wired", also known as "linked", collaboration represents

344-440: A close relationship between a buyer and supplier within the chain, whereas a loosely-coupled link relates to low interdependency between buyer and seller and therefore greater flexibility. The Chartered Institute of Procurement & Supply 's professional guidance suggests that the aim of a tightly coupled relationship is to reduce inventory and avoid stock-outs . There are a variety of supply-chain models, which address both

430-409: A company's decision-making on the number of suppliers it will engage with for each product or service as an important aspect of the design of a supply chain. Determining the number of suppliers logically precedes an RFP process for determining which suppliers will form part of the supply chain. Morgan refers to an "n + 1 rule" example in the business practice of IT component supplier Intel , whereby

516-565: A company. Starting in the 1990s, several companies chose to outsource the logistics aspect of supply-chain management by partnering with a third-party logistics provider (3PL). Companies also outsource production to contract manufacturers. Technology companies have risen to meet the demand to help manage these complex systems. Cloud-based SCM technologies are at the forefront of next-generation supply chains due to their impact on optimization of time, resources, and inventory visibility. Cloud technologies facilitate work being processed offline from

602-570: A decade or so, and nitrous oxides last about 100 years. The graph gives some indication of which regions have contributed most to human-induced climate change. When these numbers are calculated per capita cumulative emissions based on then-current population the situation is shown even more clearly. The ratio in per capita emissions between industrialized countries and developing countries was estimated at more than 10 to 1. Non- OECD countries accounted for 42% of cumulative energy-related CO 2 emissions between 1890 and 2007. Over this time period,

688-405: A fundamentally new system. This leads to a panarchical interpretation of a supply chain, embedding it into a system of systems , allowing to analyze the interactions of the supply chain with systems that operate at other levels (e.g. society, political economy, planet Earth). For example, these three components of resilience can be identified in relation to the 2021 Suez Canal obstruction , when

774-438: A global map of the organization's supply network. In the 1980s, the term supply-chain management (SCM) was developed to express the need to integrate the key business processes, from end user through original suppliers. Original suppliers are those that provide products, services, and information that add value for customers and other stakeholders. The basic idea behind SCM is that companies and corporations involve themselves in

860-442: A good or service along the supply chain to its final consumption. Carbon accounting (or greenhouse gas accounting) is a framework of methods to measure and track how much greenhouse gas an organization emits. The greenhouse effect occurs when greenhouse gases in a planet's atmosphere insulate the planet from losing heat to space, raising its surface temperature. Surface heating can happen from an internal heat source as in

946-517: A lack of comparability, which is problematic when monitoring progress towards targets. There are arguments for the adoption of a common measurement tool, or at least the development of communication between different tools. Emissions may be tracked over long time periods, known as historical or cumulative emissions measurements. Cumulative emissions provide some indicators of what is responsible for greenhouse gas atmospheric concentration build-up. The national accounts balance tracks emissions based on

1032-479: A lesser role in comparison. Emissions of carbon dioxide, methane and nitrous oxide in 2023 were all higher than ever before. Electricity generation , heat and transport are major emitters; overall energy is responsible for around 73% of emissions. Deforestation and other changes in land use also emit carbon dioxide and methane . The largest source of anthropogenic methane emissions is agriculture , closely followed by gas venting and fugitive emissions from

1118-405: A mobile app which solves the common issue of inventory residing in areas with no online coverage or connectivity. Supply chain managers are under constant scrutiny to secure the best pricing for their resources, which becomes a difficult task when faced with the inherent lack of transparency. Cost benchmarking helps to identify competitive pricing within the industry but benchmarking across

1204-862: A particular base year. Choosing between base years of 1750, 1900, 1950, and 1990 has a significant effect for most countries. Within the G8 group of countries, it is most significant for the UK, France and Germany. These countries have a long history of CO 2 emissions (see the section on Cumulative and historical emissions ). The Global Carbon Project continuously releases data about CO 2 emissions, budget and concentration. and industry (excluding cement carbonation) Gt C change Gt C Gt C Gt CO 2 (projection) Distribution of global greenhouse gas emissions based on type of greenhouse gas, without land-use change, using 100 year global warming potential (data from 2020). Total: 49.8 GtCO 2 e Carbon dioxide (CO 2 )

1290-422: A product design is completed, it drives the structure of the supply chain, limiting the flexibility of engineers to generate and evaluate different (and potentially more cost-effective) supply-chain alternatives. Design for Supply Chain is described as a process that aims to drastically reduce the product life cycle costs ... improve product quality, improve efficiency and improve profitability for all partners in

1376-440: A range of supply chain performance factors has been recommended as best practice. The SCOR model contains more than 150 key indicators which measure the performance of supply chain operations: see also Supply chain operations reference#Performance measurements . Debra Hofman has noted that "measuring supply chain performance is not a new practice. Most companies today measure at least some aspect of their supply chain and understand

1462-487: A sequence of supply chain processes in order to meet end customer buying behaviour". Many of the exchanges encountered in the supply chain take place between varied companies that seek to maximize their revenue within their sphere of interest but may have little or no knowledge or interest in the remaining players in the supply chain. More recently, the loosely coupled, self-organizing network of businesses who cooperate in providing product and service offerings has been called

1548-488: A ship blocked the canal for several days. Persistence means to "bounce back"; in our example it is about removing the ship as quickly as possible to allow "normal" operations. Adaptation means to accept that the system has reached a "new normal" state and to act accordingly; here, this can be implemented by redirecting ships around the African cape or use alternative modes of transport. Finally, transformation means to question

1634-483: A significant contributor to warming. Although CFCs are greenhouse gases, they are regulated by the Montreal Protocol which was motivated by CFCs' contribution to ozone depletion rather than by their contribution to global warming. Ozone depletion has only a minor role in greenhouse warming, though the two processes are sometimes confused in the media. In 2016, negotiators from over 170 nations meeting at

1720-461: A significant margin, Asia's and the world's largest emitter: it emits nearly 10 billion tonnes each year, more than one-quarter of global emissions. Other countries with fast growing emissions are South Korea , Iran, and Australia (which apart from the oil rich Persian Gulf states, now has the highest per capita emission rate in the world). On the other hand, annual per capita emissions of the EU-15 and

1806-515: A supply chain by exchanging information about market demand , distribution capacity and production capabilities. Keith Oliver , a consultant at Booz Allen Hamilton , is credited with the term's invention after using it in an interview for the Financial Times in 1982. The term was used earlier by Alizamir et al. in 1981, and Burns and Sivazlian in 1978. If all relevant information is accessible to any relevant company, every company in

1892-585: A supply chain seeks to match demand with supply and do so with minimal inventory . Various aspects of optimizing the supply chain include liaising with suppliers to eliminate bottlenecks; sourcing strategically to strike a balance between lowest material cost and transportation , implementing just-in-time techniques to optimize manufacturing flow; maintaining the right mix and location of factories and warehouses to serve customer markets; and using location allocation, vehicle routing analysis, dynamic programming , and traditional logistics optimization to maximize

1978-507: A supply chain, such as wholesale and retail determine their break-even point by considering transaction costs , relative to market price. Additionally, there are financial costs associated with all the stages of a supply chain model. The Global Supply Chain Forum has introduced an alternative supply chain model. This framework is built on eight key business processes that are both cross-functional and cross-firm in nature. Each process

2064-545: A year (often seasonally). The supply chain for clothing often requires constant analysis of new fashion trends to manage the quantity needed for various markets. Supply chain security has become particularly important in recent years. As a result, supply chains are often subject to global and local regulations. In the United States, several major regulations emerged in 2010 that have had a lasting impact on how global supply chains operate. These new regulations include

2150-475: Is a stub . You can help Misplaced Pages by expanding it . See guidelines for writing about climate change . Further suggestions might be found on the article's talk page . Greenhouse gas emissions Carbon dioxide (CO 2 ) is the main greenhouse gas resulting from human activities. It accounts for more than half of warming. Methane (CH 4 ) emissions have almost the same short-term impact. Nitrous oxide (N 2 O) and fluorinated gases (F-gases) play

2236-450: Is a framework of methods to measure and track how much greenhouse gas an organization emits. Cumulative anthropogenic (i.e., human-emitted) emissions of CO 2 from fossil fuel use are a major cause of global warming , and give some indication of which countries have contributed most to human-induced climate change. In particular, CO 2 stays in the atmosphere for at least 150 years and up to 1000 years, whilst methane disappears within

2322-517: Is a high-level, industry-neutral enterprise process model that allows organizations to see their business processes from a cross-industry viewpoint. The PCF was developed by APQC and its member organizations as an open standard to facilitate improvement through process management and benchmarking, regardless of industry, size, or geography. The PCF organizes operating and management processes into 12 enterprise-level categories, including process groups, and over 1,000 processes and associated activities. In

2408-421: Is exported. In comparison, methane has not increased appreciably, and N 2 O by 0.25% y . Using different base years for measuring emissions has an effect on estimates of national contributions to global warming. This can be calculated by dividing a country's highest contribution to global warming starting from a particular base year, by that country's minimum contribution to global warming starting from

2494-526: Is in terms of creating demand. In other words, it is the ability of a product's design to generate demand by satisfying customer expectations. But product design affects not only demand generation but also manufacturing processes, cost, quality, and lead time. The product design affects the associated supply chain and its requirements directly, including manufacturing, transportation, quality, quantity, production schedule, material selection, production technologies, production policies, regulations, and laws. Broadly,

2580-463: Is increasingly being utilized in supply chain management, especially in the strategic purchasing and supply management sector. Effective application of big data can improve the performance of supply chain activities through improved decision-making capabilities. Moore et al. note a trend towards strategic supply-base reduction as a mechanism for leading businesses to reduce costs and improve supplier-related performance, and similarly Ogden identifies

2666-448: Is managed by a cross-functional team including representatives from logistics, production, purchasing, finance, marketing, and research and development. While each process interfaces with key customers and suppliers, the processes of customer relationship management and supplier relationship management form the critical linkages in the supply chain.

2752-402: Is more significant than ever. In addition, as supply, and therefore competition, among companies for the limited market demand increases and as pricing and other marketing elements become less distinguishing factors, product design likewise plays a different role by providing attractive features to generate demand. In this context, demand generation is used to define how attractive a product design

2838-454: Is the dominant emitted greenhouse gas, while methane ( CH 4 ) emissions almost have the same short-term impact. Nitrous oxide (N 2 O) and fluorinated gases (F-gases) play a lesser role in comparison. Greenhouse gas emissions are measured in CO 2 equivalents determined by their global warming potential (GWP), which depends on their lifetime in the atmosphere. Estimations largely depend on

2924-563: Is the first major source of greenhouse gas emissions from transportation, followed by aircraft and maritime. Waterborne transportation is still the least carbon-intensive mode of transportation on average, and it is an essential link in sustainable multimodal freight supply chains . Buildings, like industry, are directly responsible for around one-fifth of greenhouse gas emissions, primarily from space heating and hot water consumption. When combined with power consumption within buildings, this figure climbs to more than one-third. Within

3010-665: Is very complex, and is affected by how carbon sinks are allocated between regions and the dynamics of the climate system . The graphic shows the logarithm of 1850–2019 fossil fuel CO 2 emissions; natural log on left, actual value of Gigatons per year on right. Although emissions increased during the 170-year period by about 3% per year overall, intervals of distinctly different growth rates (broken at 1913, 1945, and 1973) can be detected. The regression lines suggest that emissions can rapidly shift from one growth regime to another and then persist for long periods of time. The most recent drop in emissions growth – by almost 3 percentage points –

3096-702: The extended enterprise , and the use of the term "chain" and the linear structure it appears to represent have been criticized as "harder to relate to the way supply networks really operate. A chain is actually a complex and dynamic supply and demand network. As part of their efforts to demonstrate ethical practices , many large companies and global brands are integrating codes of conduct and guidelines into their corporate cultures and management systems . Through these, corporations are making demands on their suppliers (facilities, farms, subcontracted services such as cleaning, canteen, security etc.) and verifying, through social audits , that they are complying with

3182-458: The 2013 Savar building collapse with more than 1,100 victims have led to widespread discussions about corporate social responsibility across global supply chains. Wieland and Handfield (2013) suggest that companies need to audit products and suppliers and that supplier auditing needs to go beyond direct relationships with first-tier suppliers (those who supply the main customer directly). They also demonstrate that visibility needs to be improved if

3268-659: The European Commission issued a Communication concerning "a better functioning food supply chain in Europe", addressing the three sectors of the European economy which comprise the food supply chain: agriculture, food processing industries, and the distribution sectors. An earlier interim report on food prices (published in December 2008) had already raised concerns about the food supply chain. Arising out of

EU's draft supply chain law are due diligence requirements to protect human rights and the environment in the supply chain. With the increasing globalization and easier access to different kinds of alternative products in today's markets, the contribution of product design to generating demand

3440-538: The Kyoto Protocol methods are being sought to seek a reduction of these emissions. In 2003 the Government attempted to impose an Agricultural emissions research levy on farmers to fund research into agricultural emissions reduction but it proved to be unpopular and the proposal was abandoned. The PGGRC is an alternative method of addressing agricultural emissions. An independent review in 2006 found that

3526-418: The fossil-fuel industry . The largest agricultural methane source is livestock . Agricultural soils emit nitrous oxide partly due to fertilizers . Similarly, fluorinated gases from refrigerants play an outsized role in total human emissions. The current CO 2 -equivalent emission rates averaging 6.6 tonnes per person per year, are well over twice the estimated rate 2.3 tons required to stay within

3612-549: The required standard . A lack of transparency in the supply chain can bar consumers from knowledge of where their purchases originated and facilitate socially irresponsible practices. In 2018, the Loyola University Chicago 's Supply and Value Chain Center found in a survey that 53% of supply chain professionals considered ethics to be "extremely" important to their organization. Marshall L. Fisher (1997) asks

3698-520: The 2030 Paris Agreement increase of 1.5 °C (2.7 °F) over pre-industrial levels. While cities are sometimes considered to be disproportionate contributors to emissions, per-capita emissions tend to be lower for cities than the averages in their countries. A 2017 survey of corporations responsible for global emissions found that 100 companies were responsible for 71% of global direct and indirect emissions , and that state-owned companies were responsible for 59% of their emissions. China is, by

3784-407: The 2030 Paris Agreement increase of 1.5 °C (2.7 °F) over pre-industrial levels. Annual per capita emissions in the industrialized countries are typically as much as ten times the average in developing countries. The carbon footprint (or greenhouse gas footprint ) serves as an indicator to compare the amount of greenhouse gases emitted over the entire life cycle from the production of

3870-498: The EU, the agricultural sector presently accounts for roughly 10% of total greenhouse gas emissions, with methane from livestock accounting for slightly more than half of 10%. Estimates of total CO 2 emissions do include biotic carbon emissions, mainly from deforestation. Including biotic emissions brings about the same controversy mentioned earlier regarding carbon sinks and land-use change. The actual calculation of net emissions

3956-526: The Earth can cool off. The major anthropogenic (human origin) sources of greenhouse gases are carbon dioxide (CO 2 ), nitrous oxide ( N 2 O ), methane and three groups of fluorinated gases ( sulfur hexafluoride ( SF 6 ), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs, sulphur hexafluoride (SF 6 ), and nitrogen trifluoride (NF 3 )). Though the greenhouse effect is heavily driven by water vapor , human emissions of water vapor are not

4042-585: The PGGRC was producing world-leading research and is excellent value for money. The partners in the consortium are: Associate members are the Ministry of Agriculture and Forestry , NIWA and Foundation for Research, Science and Technology . Research is carried out by AgResearch, DairyNZ, LIC and Lincoln University . This article about an organisation in New Zealand is a stub . You can help Misplaced Pages by expanding it .

4128-718: The US accounted for 28% of emissions; the EU, 23%; Japan, 4%; other OECD countries 5%; Russia, 11%; China, 9%; India, 3%; and the rest of the world, 18%. The European Commission adopted a set of legislative proposals targeting a reduction of the CO 2 emissions by 55% by 2030. Overall, developed countries accounted for 83.8% of industrial CO 2 emissions over this time period, and 67.8% of total CO 2 emissions. Developing countries accounted for industrial CO 2 emissions of 16.2% over this time period, and 32.2% of total CO 2 emissions. However, what becomes clear when we look at emissions across

4214-552: The US are gradually decreasing over time. Emissions in Russia and Ukraine have decreased fastest since 1990 due to economic restructuring in these countries. 2015 was the first year to see both total global economic growth and a reduction of carbon emissions. Annual per capita emissions in the industrialized countries are typically as much as ten times the average in developing countries. Due to China's fast economic development, its annual per capita emissions are quickly approaching

4300-419: The ability of oceans and land sinks to absorb these gases. Short-lived climate pollutants (SLCPs) including methane, hydrofluorocarbons (HFCs) , tropospheric ozone and black carbon persist in the atmosphere for a period ranging from days to 15 years; whereas carbon dioxide can remain in the atmosphere for millennia. Reducing SLCP emissions can cut the ongoing rate of global warming by almost half and reduce

4386-538: The assumptions of globalization, outsourcing, and linear supply chains and to envision alternatives; in this example this could lead to local and circular supply chains. Supply chain resilience has been identified as an important business issue. The United Kingdom's Confederation of British Industry reported in 2014 that a significant number of businesses had reshored parts of their supply chain to European locations, with many identifying supply chain resilience as "a key factor in their decision to do so". Incidents like

4472-516: The case of Jupiter , or from its host star as in the case of the Earth . In the case of Earth, the Sun emits shortwave radiation ( sunlight ) that passes through greenhouse gases to heat the Earth's surface. In response, the Earth's surface emits longwave radiation that is mostly absorbed by greenhouse gases. The absorption of longwave radiation prevents it from reaching space, reducing the rate at which

4558-667: The concentration of carbon dioxide and other greenhouse gases. Emissions have grown rapidly since about 1950 with ongoing expansions in global population and economic activity following World War II. As of 2021, measured atmospheric concentrations of carbon dioxide were almost 50% higher than pre-industrial levels. The main sources of greenhouse gases due to human activity (also called carbon sources ) are: Global greenhouse gas emissions are about 50 Gt per year and for 2019 have been estimated at 57 Gt CO 2 eq including 5 Gt due to land use change. In 2019, approximately 34% [20 GtCO 2 -eq] of total net anthropogenic GHG emissions came from

4644-598: The developing country public health setting, John Snow, Inc. has developed the JSI Framework for Integrated Supply Chain Management in Public Health, which draws from commercial sector best practices to solve problems in public health supply chains. Similarly, supply chain mapping involves documenting information regarding all participants in an organization's supply chain and assembling the information as

4730-413: The difference between a country's exports and imports. For many richer nations, the balance is negative because more goods are imported than they are exported. This result is mostly due to the fact that it is cheaper to produce goods outside of developed countries, leading developed countries to become increasingly dependent on services and not goods. A positive account balance would mean that more production

4816-620: The difficulty of "keeping a supply chain with India unbroken" during the British expedition to Tibet . A typical supply chain can be divided into two stages namely, production and distribution stages. In the production stage, components and semi-finished parts are produced in manufacturing centres. The components are then put together in an assembly plant. The distribution stage consists of central and regional distribution centres that transport products to end-consumers. Mentzer et al. suggest that at least three entities are required for there to be

4902-538: The efficiency of distribution. The term "logistics" applies to activities within one company or organization involving product distribution, whereas "supply chain" additionally encompasses manufacturing and procurement, and therefore has a much broader focus as it involves multiple enterprises (including suppliers, manufacturers, and retailers) working together to meet a customer need for a product or service. However, John Mills et al . note that "early research" on supply chains focused on internal supply relationships within

4988-483: The enacting of policies that can improve occupational safety and health management in organizations. In fact, international organizations with presence in other nations have a responsibility to ensure that workers are well protected by policies in an organization to avoid safety related incidents. Many agribusinesses and food processors source raw materials from smallholder farmers. This is particularly true in certain sectors, such as coffee , cocoa and sugar . Over

Global carbon dioxide emissions by country in 2023: The current CO 2 -equivalent emission rates averaging 6.6 tonnes per person per year, are well over twice the estimated rate 2.3 tons required to stay within

5160-407: The face of change". For a long time, the interpretation of resilience in the sense of engineering resilience (or robustness) prevailed in supply chain management, leading to the notion of persistence . A popular implementation of this idea is given by measuring the time-to-survive and the time-to-recover of the supply chain, allowing identification of weak points in the system. More recently,

5246-547: The flow of information and finances is part of the chain as well as the product or service. Fazel Zarandi et al. add "buyer-seller relations" (at each stage), in addition to the flow of information, as the third main component of a supply chain. Mentzer et al. remind readers also that the focus of a supply chain is on the product or service in its end state: they refer to "the supply chain for candy " and "the supply chain for clothing". Individual supply chain actors may be positioned at different points in different supply chains:

SECTION 60

5332-824: The importing country, rather than the exporting, country. A substantial proportion of CO 2 emissions is traded internationally. The net effect of trade was to export emissions from China and other emerging markets to consumers in the US, Japan, and Western Europe. Emission intensity is a ratio between greenhouse gas emissions and another metric, e.g., gross domestic product (GDP) or energy use. The terms "carbon intensity" and " emissions intensity " are also sometimes used. Emission intensities may be calculated using market exchange rates (MER) or purchasing power parity (PPP). Calculations based on MER show large differences in intensities between developed and developing countries, whereas calculations based on PPP show smaller differences. Carbon accounting (or greenhouse gas accounting)

5418-470: The interpretations of resilience in the sense of ecological resilience and social–ecological resilience have led to the notions of adaptation and transformation , respectively. A supply chain is thus interpreted as a social-ecological system which – similar to an ecosystem (e.g. forest) – is able to constantly adapt to external environmental conditions and – through the presence of social actors and their ability to foresight – also to transform itself into

5504-474: The lapse of formerly declining trends in carbon intensity of both developing and developed nations. China was responsible for most of global growth in emissions during this period. Localised plummeting emissions associated with the collapse of the Soviet Union have been followed by slow emissions growth in this region due to more efficient energy use , made necessary by the increasing proportion of it that

5590-721: The levels of those in the Annex I group of the Kyoto Protocol (i.e., the developed countries excluding the US). Africa and South America are both fairly small emitters, accounting for 3-4% of global emissions each. Both have emissions almost equal to international aviation and shipping. There are several ways of measuring greenhouse gas emissions. Some variables that have been reported include: These measures are sometimes used by countries to assert various policy/ethical positions on climate change. The use of different measures leads to

5676-500: The main international treaty on climate change (the UNFCCC ), countries report on emissions produced within their borders, e.g., the emissions produced from burning fossil fuels. Under a production-based accounting of emissions, embedded emissions on imported goods are attributed to the exporting, rather than the importing, country. Under a consumption-based accounting of emissions, embedded emissions on imported goods are attributed to

5762-459: The major source of greenhouse gas emissions in the EU . Greenhouse gas emissions from the transportation sector continue to rise, in contrast to power generation and nearly all other sectors. Since 1990, transportation emissions have increased by 30%. The transportation sector accounts for around 70% of these emissions. The majority of these emissions are caused by passenger vehicles and vans. Road travel

5848-483: The motives for and performance efficacy of vertical integration differ by global region. Incorporating SCM successfully leads to a new kind of competition on the global market, where competition is no longer of the company-versus-company form but rather takes on a supply-chain-versus-supply-chain form. The primary objective of SCM is to fulfill customer demands through the most efficient use of resources, including distribution capacity, inventory , and labor. In theory,

5934-409: The need for a more comprehensive measurement program." However, the abundance of options for potential performance metrics to use is seen as a challenge for supply chain managers. One approach is to relate multiple measures in a hierarchical structure so that interdependencies and the contribution of multiple indicators to the "key" or most significant metrics can be more easily seen. Hofman suggests that

6020-443: The past 20 years, there has been a shift towards more traceable supply chains. Rather than purchasing crops that have passed through several layers of collectors, firms are now sourcing directly from farmers or trusted aggregators. The drivers for this change include concerns about food safety , child labor and environmental sustainability as well as a desire to increase productivity and improve crop quality. In October 2009,

6106-476: The projected Arctic warming by two-thirds. Supply chain A supply chain is a complex logistics system that consists of facilities that convert raw materials into finished products and distribute them to end consumers or end customers . Meanwhile, supply chain management deals with the flow of goods in distribution channels within the supply chain in the most efficient manner. In sophisticated supply chain systems , used products may re-enter

6192-469: The question in a key article, "Which is the right supply chain for your product?" Fisher, and also Naylor, Naim and Berry (1999), identify two matching characteristics of supply chain strategy: a combination of "functional" and "efficient", or a combination of "responsive" and "innovative" (Harrison and Godsell). Mentzer et al. distinguish between "direct supply chains", "extended supply chains", and "ultimate supply chains"; in their usage: In each case,

6278-406: The success of the supply chain depends on the product design and the capabilities of the supply chain, but the reverse is also true: the success of the product depends on the supply chain that produces it. According to an industrial engineering study which looked at a process for Design for Supply Chain (DFSC), since the product design imposes multiple requirements on the supply chain, then once

6364-629: The summit of the United Nations Environment Programme reached a legally binding accord to phase out hydrofluorocarbons (HFCs) in the Kigali Amendment to the Montreal Protocol . The use of CFC-12 (except some essential uses) has been phased out due to its ozone depleting properties. The phasing-out of less active HCFC-compounds will be completed in 2030. Starting about 1750, industrial activity powered by fossil fuels began to significantly increase

6450-554: The supplier's supplier to the customer's customer". It includes delivery and order fulfillment performance, production flexibility, warranty and returns processing costs, inventory and asset turns, and other factors in evaluating the overall effective performance of a supply chain. A supply chain can often be split into different segments: the earlier stages of a supply chain, such as raw material processing and manufacturing , determine their break-even point by considering production costs relative to market price. The later stages of

6536-471: The supply cannot be directly controlled and that smart and electronic technologies play a key role to improve visibility. Finally, they highlight that collaboration with local partners, across the industry and with universities is crucial to successfully manage social responsibility in supply chains. This incident also highlights the need to improve workers safety standards in organizations. Hoi and Lin (2012) note that corporate social responsibility can influence

6622-467: The supply chain at any point where residual value is recyclable. Supply chains link value chains . Suppliers in a supply chain are often ranked by "tier", with first-tier suppliers supplying directly to the client, second-tier suppliers supplying to the first tier, and so on. The phrase "supply chain" may have been first published in a 1905 article in The Independent which briefly mentions

6708-414: The supply chain has the ability to help optimize the entire supply chain rather than to sub-optimize based on local optimization. This will lead to better-planned overall production and distribution, which can cut costs and give a more attractive final product, leading to better sales and better overall results for the companies involved. This is one form of vertical integration . Yet, it has been shown that

6794-418: The supply chain. Supply chain consultant Anthony Tarantino has identified a number of best practices affecting the resilience and operation of supply chains, including the formation of multi-disciplinary centres of excellence, hybrid supply chain organizations which optimize the balance between centralization and de-centralization, and more extensive use of both structured and unstructured data . Big data

6880-446: The three key indicators of a well-functioning supply chain are: A Cranfield University boardroom survey in 2010 found evidence that many organizations recognized the importance of the supply chain contribution to their business success, with a focus on cost, customer lead-time and customer quality being the primary performance indicators. Supply chain resilience is "the capacity of a supply chain to persist, adapt, or transform in

6966-497: The two reports, the Commission established a "European Food Prices Monitoring Tool", an initiative developed by Eurostat and intended to "increase transparency in the food supply chain". In March 2022 the Commission noted "the need for EU agriculture and food supply chains to become more resilient and sustainable". The supply chain in the fashion industries has some unique properties, as clothing fashion changes several times

7052-569: The upstream and downstream elements of supply-chain management (SCM). The SCOR ( Supply-Chain Operations Reference ) model, developed by a consortium of industry and the non-profit Supply Chain Council (now part of APICS ) became the cross-industry de facto standard defining the scope of supply-chain management. SCOR measures total supply-chain performance. It is a process reference model for supply-chain management, extending "from

7138-457: The world today is that the countries with the highest emissions over history are not always the biggest emitters today. For example, in 2017, the UK accounted for just 1% of global emissions. In comparison, humans have emitted more greenhouse gases than the Chicxulub meteorite impact event which caused the extinction of the dinosaurs . Transport, together with electricity generation , is

7224-582: The year 1995). A country's emissions may also be reported as a proportion of global emissions for a particular year. Another measurement is of per capita emissions. This divides a country's total annual emissions by its mid-year population. Per capita emissions may be based on historical or annual emissions. One way of attributing greenhouse gas emissions is to measure the embedded emissions (also referred to as "embodied emissions") of goods that are being consumed. Emissions are usually measured according to production, rather than consumption. For example, in

7310-406: Was at about the time of the 1970s energy crisis . Percent changes per year were estimated by piecewise linear regression on the log data and are shown on the plot; the data are from The Integrated Carbon Observation system. The sharp acceleration in CO 2 emissions since 2000 to more than a 3% increase per year (more than 2 ppm per year) from 1.1% per year during the 1990s is attributable to

7396-527: Was occurring within a country, so more operational factories would increase carbon emission levels. Emissions may also be measured across shorter time periods. Emissions changes may, for example, be measured against the base year of 1990. 1990 was used in the United Nations Framework Convention on Climate Change (UNFCCC) as the base year for emissions, and is also used in the Kyoto Protocol (some gases are also measured from
