Chapter One: When is Free Trade Good for the Environment? This paper provides the conditions under which free trade reduces the emission of pollution. In this paper, we construct a computable general equilibrium model of free trade and environment. Using data from different countries with different characteristics with respect to the stringency of their environmental and trade policies and factor endowments, we simulate a reduction on import tariffs and measure the impact on the volume of emission. Our main findings show that, for a combination of relatively high capital to labour ratio and low level of protectionism, if a country exports the polluting good then, trade liberalization increases the level of emission. Whereas if the country exports the clean good, then the effect of an import tariff reduction on the emission level is positively related to the variation in the producer’s price of the polluting good. Furthermore, we find that under a relatively low level of capital endowment for a country that exports the polluting good, the impact of free trade on the environment depends on the degree of protectionism. // Chapter Two: Ageing and the Environment in an Overlapping Generations Model. We empirically investigate the impact of population ageing on the environment using an overlapping generations model. We decompose the impact into scale, composition, and cohort effects. Using data from the Canadian economy, we simulate the impact of demographic shock on the volume of emission. Population ageing results mostly from a baby bust that follows a baby boom. The demographic transition is characterized by an increase then a decline in the population growth rate. Under the first part of the transition, we find that the scale effect generates more pollution. However, if young generations are more concerned about the environment, an increase in the population growth rate may improve the environment via the composition effects. On the other hand, a decline in the population growth rate (population ageing) creates the opposite results. We further find that cohort effect is positively related to the environment when there is a higher degree of awareness towards a cleaner environment. By comparing scale to both composition and cohort effects, we find that scale dominates both effects, so population ageing causes the level of pollution to fall. // Chapter Three: Does Population Ageing in the North Leads to More Pollution in the South? We construct a two-country model: a rich country (the North) with relatively high level of capital endowment and stringent environmental policy and a poor country (the South) with less stringent environmental policy. Both countries produce a clean and a polluting good and both have access to an exogenous abatement technology. The paper has three main foci. First, it provides an empirical test for the pollution haven and the factor endowment hypotheses. Second, it introduces the issue of population ageing in the North into the question of trade liberalisation and the environment. Finally, it investigates the impact of demographic and trade shocks on the level of emissions in both countries. Results from simulations suggest that an increase in the population growth rate increases the volume of emission in the long run. However, population-ageing generates an opposite effect. In the short term, the scale dominates the composition effect. Empirical evidences show that the level of emission is positively related to the size of population. With respect to trade, pollution increases in the North and falls in the South. Also, we find that demographic changes dominate trade liberalization. Finally, worldwide free trade is bad for the environment, but its effect is marginal.

Environmental protection and the World Trade Organization Klára Šmídlová Abstract The theme of this diploma thesis is the relationship of the World Trade Organization (WTO) to the environmental protection. In its three chapters, this paper carries out an analysis of the historical aspects of this relationship and also of the questions, which are being solved in the present. The first chapter outlines the evolution of the relationship between the international trade and the environmental protection since 1947 when the General Agreement on Tariffs and Trade was concluded. The second part of the paper focuses on the analysis of the provisions of the particular WTO agreements, which approach the issue of the environmental protection in different ways. The case law established by the WTO bodies during solving of the disputes between the member states is especially emphasised in analysis of the provisions of the WTO agreements. Finally, the last chapter is devoted to the research of the relationship between the WTO and multilateral environmental agreements, above all those making use of the trade measures to achieve their goals.

Trade unions and environmental movements are often seen as political opponents most prominently discussed in the form of the "jobs vs. environment dilemma". Based on historical examples of the conflict relations between trade unions and environmental groups in the Austrian energy sector, this paper showcases how the relationship between the two groups has changed from enmity to first attempts at alliance building. Drawing from analysis of union documents and problem-centred interviews conducted with Austrian unionists, it shows that newly emerging alliances between unions and environmental movements contain the seeds for a broad societal movement that can help overcome the paradigm of growth and actively engage in the creation of policies that support a social-ecological transformation.

Most countries show a relative decoupling of economic growth from domestic resource use, implying increased resource efficiency. However, international trade facilitates the exchange of products between regions with disparate resource productivity. Hence, for an understanding of resource efficiency from a consumption perspective that takes into account the impacts in the upstream supply chains, there is a need to assess the environmental pressures embodied in trade. We use EXIOBASE3, a new multiregional input-output database, to examine the rate of increase in resource efficiency, and investigate the ways in which international trade contributes to the displacement of pressures on the environment from the consumption of a population. We look at the environmental pressures of energy use, greenhouse gas (GHG) emissions, material use, water use, and land use. Material use stands out as the only indicator growing in both absolute and relative terms to population and gross domestic product (GDP), while land use is the only indicator showing absolute decoupling from both references. Energy, GHG, and water use show relative decoupling. As a percentage of total global environmental pressure, we calculate the net impact displaced through trade rising from 23% to 32% for material use (1995¿2011), 23% to 26% for water use, 20% to 29% for energy use, 20% to 26% for land use, and 19% to 24% for GHG emissions. The results show a substantial disparity between trade-related impacts for Organization for Economic Cooperation and Development (OECD) and non-OECD countries. At the product group level, we observe the most rapid growth in environmental footprints in clothing and footwear. The analysis points to implications for future policies aiming to achieve environmental targets, while fully considering potential displacement effects through international trade.

In this paper, we analyse the effects of a unilateral change in an emissions tax in a model of international trade with heterogeneous firms. We find a positive effect of tighter environmental policy on average productivity in the reforming country through reallocation of labour towards exporting firms. Domestic aggregate emissions fall, due to both a scale and a technique effect, but we show that the reduction in emissions following the tax increase is smaller than in autarky. Moreover, general equilibrium effects through changes in the foreign wage rate lead to a reduction in foreign emissions and, hence, to negative emissions leakage in case of transboundary pollution.

<p>The thesis concentrates on Hofors and a local trade union environment between 1917 and 1946, where important parts of the trade union’s power were held by parties to the left of the social democrats.

The thesis concentrates on Hofors and a local trade union environment between 1917 and 1946, where important parts of the trade union’s power were held by parties to the left of the social democrats. The overall aim is to problemize and discuss the issue of what characterised and made possible this deviation from the usual picture of a trade union movement dominated by social democracy. What characterised the conditions in such a local trade union environment and to what extent can local norms and political culture be linked to the conditions and the development in the trade union movement in Hofors? The factors behind the radicalism in Hofors can be found in the local union and political context. The investigation points out the following main reasons: the left-wing local council of the Social Democratic Party and its successors’ organisational lead, the local labour council’s working method being close to what has been considered “social democratic”, their representatives being highly trusted in the local community, and the growth of a local radical tradition. The political culture and the norms that gradually developed were based on a left-wing social democratic tradition. The local council of the Social Democratic Party that left the party in 1917 to join the left-wing social democratic faction was the same local council, despite their names and change of parties in the 1920s and 1930s. It became the local labour movement’s bearer of traditions and represented the continuity in the local trade union environment, which contributed to the leftwing socialist project being long-lived in Hofors. The central aspects were the trade union work and the practical-concrete tradition that developed. Primarily through successful trade union work, the local labour council and its trade union representatives gained strong and long-term support from a large proportion of the local trade union movement’s members and the population of Hofors. Against this background it may be stated that, even though it was often impossible for the parties to the left of social democracy to maintain a local trade union and political power position that was stronger than that of the social democrats for a lengthy period of time, it was not entirely impossible. It may also be stated that for the trade union member as such, a communist or socialist party affiliation was not a real obstacle in the election of shop stewards. Their focus was primarily put on the would-be representatives’ personal qualities and ability to live up to the demands and expectations placed on them by the members, and not so much on their ideological persuasion.
