Economic growth and atmospheric pollution in Spain: discussing the environmental Kuznets curve hypothesis

The environmental Kuznets curve (EKC) hypothesis posits an inverted U relationship between environmental pressure and per capita income. Recent research has examined this hypothesis for different pollutants in different countries. Despite certain empirical evidence shows that some environmental pressures have diminished in developed countries, the hypothesis could not be generalized to the global relationship between economy and environment at all. In this article we contribute to this debate analyzing the trends of annual emission flux of six atmospheric pollutants in Spain. The study presents evidence that there is not any correlation between higher income level and smaller emissions, except for SO2 whose evolution might be compatible with the EKC hypothesis. The authors argue that the relationship between income level and diverse types of emissions depends on many factors. Thus it cannot be thought that economic growth, by itself, will solve environmental problems.

Intergenerational equity and sustainability

Abstract This paper explores the limitations of conventional economic analysis of intergenerational problems and examines some of the alternatives suggested in the literature. It is argued that proper consideration of future generations has at least three requirements. First, when future costs and benefits are considered, it should be taken into account that they are to be enjoyed by different generations. Second, the sustainability requirement should be adopted. This represents an equity commitment to the future and implies the recognition that future generations have the right to nondeteriorated ecological and economic capacity. The paper studies the ways in which the recognition of these rights might be incorporated into economic evaluation and management. Third, an appropriate institutional network to enforce the recognition of these rights in decision-making processes should be constituted. Its design and necessary functions are also analyzed.

Key sectors in final energy consumption: an input-output application to the Spanish case

Abstract In this paper we analyze the determination of “key” sectors in the final energy consumption. We approach this issue from an input–output perspective and we design a methodology based on the elasticities of the demands of final energy consumption. As an exercise, we apply the proposed methodology to the Spanish economy. The analysis allows us to indicate the greater or lesser relevance of the different sectors in the consumption of final energy, pointing out which sectors deserve greater attention in the Spanish case and showing the implications for energy policy.

Climate Change, Economic Analysis and Sustainable Development

This paper discusses the limitations, omissions and value judgements of the application of conventional economic analysis in the evaluation of climate change mitigation policies. It is argued that these have biased the result of the assessment models towards the recommendation of less aggressive mitigation strategies. Consequently, this paper questions whether they provide appropriate policy recommendations. The unequal distribution of rights implicitly assumed in conventional economic analyses applied to climate change is questioned and an alternative approach considering a distribution of rights consistent with sustainable development is put forward. Finally, the points that an analysis consistent with sustainable development should take into account are presented.

The Proposals for a European Tax on CO2 and Their Implications for Intercountry Distribution

This paper analyzes the advantages andimplications of the implementation of aEuropean tax on carbon dioxide emissions as anown resource of the EU and it focuses on itseffects on intercountry distribution. Incontrast to a harmonized tax, which would onlyhave distributive effects within each memberstate, a tax collected at European scale wouldalso have important distributive effects amongdifferent countries. These effects would alsodepend on the use of tax revenues. The paperinvestigates through a simple empiricalanalysis the distributive effects among themember states of three tax models: a pureCO2 model; a 50%/50% energy-CO2model and a CO2 model with a burden onnuclear power.

GREENHOUSE GAS EMISSIONS AND ECONOMIC STRUCTURE IN URUGUAY

Using input–output analysis, we identify the key sectors in greenhouse gas (GHG) emissions of the Uruguayan economy. The responsibilities of each sector in terms of its emissions are decomposed into an own component, generated during the activities of the sector, and an indirect component, generated by the induced activities in other sectors. This has important implications for the design of mitigation polices, as the appropriate policy measures are contingent on the nature of the pollution. Technical improvements and best practices are effective only when applied to directly polluting sectors, while demand policies may be more appropriate for indirectly polluting sectors. In addition, we analyze pollution generated during the production of exports. The results show that demand policies are going to be effective in the Building, the Hotel and restaurants, and the Wholesale and retail trade; and repair of motor vehicles and motorcycles sectors. These policies complement GHG emissions’ mitigation policies in directly polluting sectors (mainly the Cattle farming and the transport-related sectors). Finally, methane and nitrous oxide emissions are mainly the consequence of production for exports, while carbon dioxide emissions are mainly driven by production for domestic consumption.

The causal factors of international inequality in co2 emissions per capita: a regression-based inequality decomposition analysis

This paper uses the possibilities provided by the regression-based inequality decomposition (Fields, 2003) to explore the contribution of different explanatory factors to international inequality in CO2 emissions per capita. In contrast to previous emissions inequality decompositions, which were based on identity relationships (Duro and Padilla, 2006), this methodology does not impose any a priori specific relationship. Thus, it allows an assessment of the contribution to inequality of different relevant variables. In short, the paper appraises the relative contributions of affluence, sectoral composition, demographic factors and climate. The analysis is applied to selected years of the period 1993–2007. The results show the important (though decreasing) share of the contribution of demographic factors, as well as a significant contribution of affluence and sectoral composition.

Seven Reasons to Use Carbon Pricing in Climate Policy

Carbon pricing is a recurrent theme in debates on climate policy. Discarded at the 2009 COP in Copenhagen, it remained part of deliberations for a climate agreement in subsequent years. As there is still much misunderstanding about the many reasons to implement a global carbon price, ideological resistance against it prospers. Here, we present the main arguments for carbon pricing, to stimulate a fair and well�?informed discussion about it. These include considerations that have received little attention so far. We stress that a main reason to use carbon pricing is environmental effectiveness at a relatively low cost, which in turn contributes to enhance social and political acceptability of climate policy. This includes the property that corrected prices stimulate rapid environmental innovations. These arguments are underappreciated in the public debate, where pricing is frequently downplayed and the erroneous view that innovation policies are sufficient is widespread. Carbon pricing and technology policies are, though, largely complementary and thus are both needed for effective climate policy. We also comment on the complementarity of other instruments to carbon pricing. We further discuss distributional consequences of carbon pricing and present suggestions on how to address these. Other political economy issues that receive attention are lobbying, co�?benefits, international policy coordination, motivational crowding in/out, and long�?term commitment. The overview ends with reflections on implementing a global carbon price, whether through a carbon tax or emissions trading. The discussion goes beyond traditional arguments from environmental economics by including relevant insights from energy research and innovation studies as well.
