Green economy policies in Canada are policies that contribute to transitioning the Canadian economy to a more environmentally sustainable one.
 The green economy can be defined as an economy, “that results in improved human well-being and social equity, while significantly reducing environmental risks and ecological scarcities.”
 Aspects of a green economy would include stable growth in income and employment that is driven by private and public investment into policies and actions that reduce carbon emissions, pollution and prevent the loss of biodiversity.Green economy policies can be defined as legislation or actions put forth by public institutions with the main intent of furthering establishing an environmentally sustainable system.
 Some of these policies would include investments into green energy sectors aimed at reducing carbon emissions, and aiding the growth of renewable energy resources.
 Green economy policies can also be considered on an international scale, with agreements such as the Kyoto Protocol and the Paris Agreement.
 Policies on a national level include, agreements such as the Western Climate Initiative, and the Boreal Forest Agreement among many others.
The Economy of Kosovo is a transition economy.
 Kosovo was the poorest province of the former Yugoslavia with a modern economy only established after a series of federal development subsidies in 1960s and 1970s.
 During the 1990s abolition of province's autonomous institutions followed by poor economic policies, international sanctions, little access to external trade and finance, and ethnic conflict severely damaged the already-weak economy.
 Since the declaration of independence in 2008 Kosovo's economy has grown each year, with relatively low effects from the global financial crisis; while there are many weaknesses for its potential in the future, many of them related to its internationally disputed status, there are also potential strengths, including its very low level of government debt ( as most of historical debts are paid still by Serbia) and future liabilities and the strength of its banking system (despite remaining obstacles to using this for productive loans).
 Kosovo remains one of the poorest areas of Europe, with as much as 45% of the population living below the official poverty line, and 17% being extremely poor according to the World Bank.
The British Labour Party grew out of the trade union movement of the late 19th century, and surpassed the Liberal Party as the main opposition to the Conservatives in the early 1920s.
 In the 1930s and 1940s it stressed national planning, using nationalization of industry as a tool, but it never favoured worker control of industry.
 Labour has had several spells in government, first as minority governments under Ramsay MacDonald in 1924 and 1929–31.
 MacDonald and half his cabinet split with the mainstream of the Party and were denounced as traitors.
 Labour was a junior partner in the wartime coalition from 1940–1945.
 After the famous 1945 landslide under Clement Attlee (1945–51) it set up the welfare state with the National Health Service, nationalised a fifth of the economy, joined NATO and opposed the Soviet Union in the Cold War.
 Under Harold Wilson in 1964–70 it promoted economic modernisation.
 Labour was in government again in 1974–79, under Wilson and then James Callaghan.
 Escalating economic crises (the "Winter of Discontent") and a split with David Owen and others forming the SDP, resulted in Opposition status during the Thatcher years, 1979–1990.
"C.V.G. Aluminio del Caroní S.A.", known as Alcasa, is a state-owned aluminium producer in Venezuela.
 Founded in 1960, it began operations in 1967.
 It is part of the Corporación Venezolana de Guayana mining company, and one of the world's largest aluminium producers.
 In 1999 it had around 9000 employees.
 In 2005 the BBC reported that Alcasa had instituted a "co-management" initiative, with workers electing managers and participating in the budgeting process, as well as being involved in decisions on technical issues related to production.
 The experience was evaluated negatively by President Nicolás Maduro in 2013: "The model of worker control failed in Guyana, it never existed; neither control nor worker."
The Western Sahara War (Arabic: حرب الصحراء الغربية‎ ‎ , French: "Guerre du Sahara occidental" , Spanish: "Guerra del Sahara Occidental" ) was an armed struggle between the Sahrawi indigenous Polisario Front and Morocco between 1975 and 1991, being the most significant phase of the Western Sahara conflict.
 The conflict erupted after the withdrawal of Spain from the Spanish Sahara in accordance with the Madrid Accords (signed under the pressure of the Green March), by which it transferred administrative control of the territory to Morocco and Mauritania, but not the sovereignty.
 In late 1975, Moroccan government organized the Green March of some 350,000 Moroccan citizens, escorted by around 20,000 troops, who entered Western Sahara, trying to establish a Moroccan presence.
 While at first met with just minor resistance by the POLISARIO, Morocco later engaged a long period of guerrilla warfare with the Sahrawi nationalists.
 During the late 1970s, the Polisario Front, desiring to establish an independent state in the territory, attempted to fight both Mauritania and Morocco.
 In 1979, Mauritania withdrew from the conflict after signing a peace treaty with the POLISARIO.
 The war continued in low intensity throughout the 1980s, though Morocco made several attempts to take the upper hand in 1989–1991.
 A cease-fire agreement was finally reached between the Polisario Front and Morocco in September 1991.
 Some sources put the final death toll between 10,000 and 20,000 people.
Gaston Leval (born Pierre Robert Piller October 20, 1895 – April 8, 1978) was an anarcho-syndicalist, combatant and historian of the Spanish Revolution.
A worker cooperative is a cooperative that is owned and self-managed by its workers.
 This control may be exercised in a number of ways.
 A cooperative enterprise may mean a firm where every worker-owner participates in decision-making in a democratic fashion, or it may refer to one in which management is elected by every worker-owner, and it can refer to a situation in which managers are considered, and treated as, workers of the firm.
 In traditional forms of worker cooperative, all shares are held by the workforce with no outside or consumer owners, and each member has one voting share.
 In practice, control by worker-owners may be exercised through individual, collective, or majority ownership by the workforce; or the retention of individual, collective, or majority voting rights (exercised on a one-member one-vote basis).
 A worker cooperative, therefore, has the characteristic that each of its workers own one share, and the all shares are owned by the workers.
 The International organisation representing worker cooperatives is CICOPA.
 CICOPA has two regional organisations: CECOP- CICOPA Europe and CICOPA Americas.
The New Course ( "Новый курс)" was a 1924 brochure by Bolshevik political leader Leon Trotsky.
 Frequently reprinted in various European and Asian language over subsequent decades, the tract is considered a first explicit statement of the Left Opposition within the ruling All-Union Communist Party (Bolsheviks) criticizing a trend towards bureaucracy and an attenuation of worker control over the political process.
The Spanish Revolution was a workers' social revolution that began during the outbreak of the Spanish Civil War in 1936 and resulted in the widespread implementation of anarchist and more broadly libertarian socialist organizational principles throughout various portions of the country for two to three years, primarily Catalonia, Aragon, Andalusia, and parts of the Valencian Community.
 Much of the economy of Spain was put under worker control; in anarchist strongholds like Catalonia, the figure was as high as 75%, but lower in areas with heavy influence by the Communist Party of Spain.
 Factories were run through worker committees, agrarian areas became collectivized and run as libertarian socialist communes. Even places like hotels, barber shops, and restaurants were collectivized and managed by their workers.
Capital deepening is a situation where the capital per worker is increasing in the economy.
 This is also referred to as increase in the capital intensity.
 Capital deepening is often measured by the rate of change in capital stock per labour hour.
 Overall, the economy will expand, "and" productivity per worker will increase.
 However, according to some economic models, such as the Solow model, economic expansion will not continue indefinitely through capital deepening alone.
 This is partly due to diminishing returns and wear & tear (depreciation).
 Investment is also required to increase the amount of capital available to each worker in the system and thus increase the ratio of capital to labour.
 In other economic models, for example, the AK model or some models in endogenous growth theory, capital deepening can lead to sustained economic growth even without technological progress.
 Traditionally, in development economics, capital deepening is seen as a necessary but not sufficient condition for economic development of a country.
