We investigate the environmental impacts of Russia's World Trade Organization (WTO) accession with a computable general equilibrium model incorporating imperfectly competitive firms, foreign direct investment and endogenous productivity. WTO accession increases CO2 emissions through technique (?), composition (+) and scale (+) effects. We consider three complementary policies to limit CO2 emissions: cap and trade, emission intensity standards and energy efficiency standards. With imperfectly competitive firms, gains from WTO accession result with any of these policies. If we assume perfectly competitive market structures, the negative environmental impacts of WTO accession are smaller and no net gains arise when environmental regulation involves energy intensity or efficiency standards. 相似文献

The carbon footprint of UK households 1990-2004: A socio-economically disaggregated, quasi-multi-regional input-output model 总被引:9,自引:0,他引:9
This paper presents a socio-economically disaggregated framework for attributing CO2 emissions to people's high level functional needs. Based around a quasi-multi-regional input-output (QMRIO) model, the study, in theory, takes into account all CO2 emissions that arise from energy used in production of goods and services to satisfy UK household demand, whether the emissions occur in the UK or abroad. Results show that CO2 emissions attributable to households were 15% above 1990 levels in 2004, and that although absolute decoupling occurred between household expenditure and CO2 during the UK's switch from coal to gas in the early 1990s, since then only slight relative decoupling is evident. The proportion of CO2 that arises outside UK borders in support of UK consumption is rising, and reducing these emissions is particularly problematic in a global trading system. Investigation into the carbon footprint of different segments of the UK population shows wide variation: the segment with the highest carbon footprint emits 64% more CO2 than the segment with the lowest. Results show that recreation and leisure are responsible for over one quarter of CO2 emissions in a typical UK household in 2004. We conclude that expanding lifestyle aspirations are significant factors in driving household CO2 emissions, but the study also emphasizes that attention must be paid to the infrastructures and institutions that result in considerable amounts of CO2 being locked up in basic household activities through which people meet their everyday needs for subsistence, protection, and communication with family and friends. The findings highlight the sheer scale of the challenge facing UK policy-makers, and suggest that policies should be targeted towards segments of society responsible for the highest carbon footprints. 相似文献

In this paper we test an adapted EKC hypothesis to verify the relationship between ‘environmental efficiency’ (namely emissions per unit of value added) and labour productivity (value added per employee). We exploit NAMEA data on Italy for 29 sector branches and 6 categories of air emissions for the period 1991-2001. We employ data on capital stock and trade openness to test the robustness of our results.On the basis of the theoretical and empirical analyses focusing on innovation, firm performances and environmental externalities, we would expect a positive correlation between environmental efficiency and labour productivity — a negative correlation between the emissions intensity of value added and labour productivity — which departs from the conventional mainstream view. The hypothesis tested is a critical one within the longstanding debate on the potential trade-off or complementarity between environmental preservation and economic performance, which is strictly associated with the role of technological innovation. We find that for most air emission categories there is a positive relationship between labour productivity and environmental efficiency. Labour productivity dynamics, then, seem to be complementary to a decreasing emissions intensity in the production process. Taking a disaggregate sector perspective, we show that the macro-aggregate evidence is driven by sector dynamics in a non-homogenous way across pollutants. Services tend always to show a ‘complementary’ relationship, while industry seems to be associated with inverted U-shape dynamics for greenhouse gases and nitrogen oxides. This is in line with our expectations. In any case, EKC shapes appear to drive such productivity links towards complementarity. The extent to which this evidence derives from endogenous market forces, industrial and structural change, and policy effects is discussed by taking an evolutionary perspective to innovation and by referring to impure public goods arguments. 相似文献

This paper investigates the relationship in China between trade, growth and emissions using provincial-level data for water (chemical oxygen demand: COD) and air (sulphur dioxide: SO2). It analyses the period 1990–2007 in three steps. First, the income ‘turning point’ of the Environmental Kuznets Curve (EKC) has been estimated using quadratic log function and obtained a turning point consistent with existing studies. Second, adopting Dean's (2002) simultaneous equations system, the relationships between trade, growth and emissions has been estimated and the results confirm the dominance of scale effects over technique effects. Third, the estimated per capita turning point for EKC is used to split the provincial industrial database into two groups (below and above turning point income) and simultaneous equations are estimated separately for them. The split sample provided limited support for the trade-induced emissions hypothesis for COD, but not for SO2. At the provincial level rising incomes via increased levels of international trade were associated with falling COD due to the technique effect, so that rising incomes among the provinces tended to be associated with lower emissions. Stricter environmental regulations are required for growing incomes because they may encourage better production techniques. 相似文献

Spatial organization, transport, and climate change: Comparing instruments of spatial planning and policy 总被引:2,自引:0,他引:2
Approaching the analysis of climate policies from a spatial organization perspective is necessary for realizing both efficient and effective mitigation of greenhouse gas (GHG) emissions. In particular, it allows assessing the potential contribution of specific mechanisms of spatial organization and related spatial planning and policy to climate policy goals. So far, this spatial organization angle of climate policy has hardly received attention in the literature. The main sector significantly contributing to GHG emissions and sensitive to spatial organization and planning is urban transport. A qualitative evaluation of the available spatial organization policy options is provided, on the basis of four standard ‘E criteria’ and a decomposition of CO2 emissions. 相似文献

The main objective of this paper is to analyse consumer response and welfare effects due to changes in energy or environmental policy. To achieve this objective we formulate and estimate an econometric model for non-durable consumer demand in Sweden that utilises micro- and macro-data. In the simulations, we consider two revenue neutral scenarios that both imply a doubling of the CO2 tax; one that returns the revenues in the form of a lower VAT and one that subsidise public transport. One conclusion from the simulations is that the CO2 tax has regional distribution effects, in the sense that household living in sparsely populated areas carry a larger share of the tax burden. 相似文献

With the third trading period of the EU emissions trading scheme (EU ETS) starting in 2013, the system of allocating emission
allowances will significantly change: In contrast to the previous two trading periods, auctioning of the allowances should
now be the rule rather than the exception. Accompanying this policy change, concerns over competitiveness of energy intensive,
trade exposed sectors as well as over limited environmental effectiveness via the channel of carbon leakage, have regained
prominence. In this paper, we thus explore the impacts of potential EU policies to counter losses in international competitiveness
and carbon leakage from the perspective of Austria. Based on numerical simulations with a computable general equilibrium model,
we evaluate three policy options: an input subsidy for carbon allowances (thus reflecting the planned partially free allocation
mechanism in the third EU ETS phase), a subsidy for domestic production, and an export rebate based on sectoral CO2 costs. Our results show that each policy has the potential to support domestic production in exposed sectors relative to
a full auctioning scenario and thus increase competitiveness. However, none is imperatively effective at reducing Austria’s
net carbon emissions: while the carbon trade balance is improved and hence leakage declines, the tradability of emission permits
within the EU ETS allows CO2 emissions from Austria’s ETS output to increase. A cost benefit analysis indicates that the two policies promoting domestic
output and exports are more cost effective than the CO2 input subsidy. 相似文献

In this study, we investigated global economic and environmental resilience in the presence of climate change. In particular, we examine the possibility of mitigating carbon dioxide (CO2) emissions without stressing standards of living. Here, we set up a cross-country CO2 market constrained by a quota, where CO2 is optimally re-allocated based on relative shadow prices of the pollutant. The objective is to stabilize global emissions without hindering global incomes and in the process achieve a single CO2 price. We introduce a re-allocation model that takes into account each country’s underlying polluting technology. The model solutions are then used to investigate whether a single, global price for CO2 is attainable. Our results suggest that global CO2 emissions could stabilize without stressing global incomes, with a global CO2 market achieving equilibrium. With a CO2 market, countries would then have the incentive to consider adopting, improving, or investing in additional abatement technologies to move beyond current capabilities, while continuing to increase standards of living. 相似文献

This article surveys various aspects of the measurement of environmental quality from the view point of national accounting and welfare economics. It focuses on the question whether GNP or NNP should be corrected for environmental change (green or eco-GNP) or whether physical accounts provide sufficient information for an assessment of the trade-off mentioned above. We conclude that valuation of (services from) environmental capital cannot be avoided for such assessment, but can only be made using a model based approach. Statistical agencies should continue to collect data on environmental quality and to value changes in environmental capital in the context of national resource accounting. However, official statisticians should refrain from correcting GNP or NNP for environmental change, as this correction implicitly contains a political judgment and cannot be based on mere technical knowledge. 相似文献

This study evaluates the impacts of Brazilian highway conditions on fuel consumption and, consequently, on carbon dioxide (CO2) emissions. For the purpose of this study, highway conditions refer to the level of highway maintenance: the incidence of large potholes, large surface cracks, uneven sections, and debris. Primary computer collected data related to the fuel consumption of three types of trucks were analyzed. The data were derived from 88 trips taken over six routes, each route representative of one of two highway conditions: better or worse. Study results are initially presented for each type of truck being monitored. The results are then aggregated to approximate the entire Brazilian highway network. In all cases, results confirmed environmental benefits resulting from travel over the better routes. There was found to be an increase in energy efficiency from traveling better roads, which resulted in lower fuel consumption and lower CO2 emissions. Statistical analysis of the results suggests that, in general, fuel consumption data were significant at *P < 0.05, rejecting the null hypothesis that average fuel consumption from traveling the better routes is statistically equal to average fuel consumption from traveling the worse routes. Improved Brazilian road conditions would generate economic benefits, reduce dependency on and consumption of fossil fuels (due to the increase in energy efficiency), and reduce CO2 emissions. These findings may have additional relevancy if Brazil needs to reduce carbon dioxide emissions to reach future Kyoto Protocol's emissions targets, which should take effect in January 2013. 相似文献

Sustainability assessments have become important tools for decision makers. This research assesses the sustainability of different types of tourists in New Zealand by using the concept of yield and by developing yield indicators in the areas of financial, public sector and sustainable yield. The concept and indicators have been developed in cooperation with the New Zealand tourism sector and therefore provide a sector-driven approach to implement a sustainability assessment. The analysis shows that there are numerous ‘trade-offs’ between indicators when attempting to define the ‘ideal visitor type’. Coach tourists, for example, are the largest spenders and generate the greatest Value Added in tourism on a per-day basis, but they contribute less to the financial sustainability of tourism when the costs of capital are accounted for. Coach tourists are highly concentrated in a few key destinations and at the same time produce substantial amounts of CO2 emissions due to their air travel component. In contrast, backpacker and camping tourists provide greater financial yield and are more dispersed, but they are also the greatest user of publicly provided tourist attractions and therefore come at a higher cost to government than other tourist types. Camping tourists are also contributing considerably to CO2 emissions. The yield analysis proposed in this paper could be a valuable tool for complex policy decision making and identifying strategies that lead to high-yield tourism. 相似文献

POLLUTION AND POLLUTION ABATEMENT IN THE NATIONAL ACCOUNTS 总被引:5,自引:0,他引:5
Building on the approach of Weitzman, as extended by Hartwick and Mäler, five models of national accounts in a dynamic competitive economy with pollution externalities are constructed: flow pollutants, stock pollutants, fossil fuels and CO2 , living resources and acid rain, and household defensive expenditures. The results measure welfare rather than national product per se . The general conclusions are that abatement expenditures should be treated as intermediate consumption, that adjustments need to be made for both pollution emissions and natural pollution dissipation processes, that marginal social costs should be used to value emissions, and that the level of environmental services must be valued in measuring welfare. Not only should household defensive expenditures not be subtracted from the welfare measure, under plausible assumptions the adjustment to welfare (as opposed to NNP) includes a value greater than the level of household defensive expenditure. 相似文献

Environmental impact of household activity in Spain 总被引:1,自引:0,他引:1
The objective of this paper is to analyse the environmental impacts of the Spanish economy by way of water and atmospheric pollution on the basis of a Spanish Accounting Matrix for 1999. Only households were taken as an exogenous account. The pollution measures are estimated for seven categories of pollution: three atmospheric pollutants (CO2, NOx and SOx) and four indicators for water (waste water, nitrogen, metals and biological oxygen demand (BOD)). The environmental data base was obtained from the Spanish Statistical Institute.The analysis reveals that pollution in Spain is closely linked to food production, energy, extractive industries and paper manufacturing. We show that services, taken as a whole, are major polluters, though this is due to the volume of household expenditure they represent rather than their pollution potential as such. We also show that the Spanish economy avoids a great deal of pollution by importing inputs, which pollute where they are produced. Finally, the study also provides per capita pollution values for the aforementioned seven pollutants. 相似文献

Economists are increasingly interested in forecasting future costs and benefits of policies for dealing with materials/energy fluxes, polluting emissions and environmental impacts on various scales, from sectoral to global. Computable general equilibrium (CGE) models are currently popular because they project demand and industrial structure into the future, along an equilibrium path. But they are applicable only to the extent that structural changes occur in or near equilibrium, independent of radical technological (or social) change. The alternative tool for analyzing economic implications of scenario assumptions is to use Leontief-type Input-Output (I-O) models. I-O models are unable to endogenize structural shifts (changing I-O coefficients). However, this can be a virtue when considering radical rather than incremental shifts. Postulated I-O tables can be used independently to check the internal consistency of scenarios. Or I-O models can be used to generate scenarios by linking them to econometric macro-drivers (which can, in principle, be CGE models). Explicit process analysis can be integrated, in principle, with I-O models. This hybrid scheme provides a natural means of satisfying physical constraints, especially the first and second laws of thermodynamics. This is important, to avoid constructing scenarios based on physically impossible processes. Process analysis is really the only available tool for constructing physically plausible alternative future I-O tables, and generating materials/energy and waste emissions coefficients. Explicit process analysis also helps avoid several problems characteristic of pure CGE or I-O models, viz. (1) aggregation errors (2) inability to handle arbitrary combinations of co-product and co-input relationships and (3) inability to reflect certain non-linearities such as internal feedback loops. 相似文献

In March 1997 the European Commission adopted aproposal that increases existing minimum levels oftaxation on mineral oils by around 10 to 25% andintroduces excises for other energy products. Thispaper analyses the macroeconomic impacts of theproposal. It employs three models: HERMES, GEM-E3, andE3ME. All models confirm that the proposal will havepositive macroeconomic impacts when the tax revenuesare used to reduce social security contributions paidby employers. For the EU as a whole, both GDP andemployment are expected to be higher and CO2emissions are 0.9 to 1.6 percent lower. The positiveEU-wide effects can be observed in practically allmember states. The sector impacts are modest, with theenergy sector expected to face the most negativeimpacts. Differences between model results are due tothe model type (general equilibrium ormacro-econometric), the EU countries covered and theway tax exemptions were handled. Crucial assumptionsto obtain the ``double dividend' are the modelling ofthe labour market and the impacts on EU externaltrade. The sensitivity of the results for the use oftax revenues, tax exemptions and tax rate increases isassessed. 相似文献

A computable general equilibrium model with specific detail in taxation and energy use is developed in this paper to quantify the impact of the implementation of energy taxation to reduce carbon dioxide emissions in Ireland. Benchmark data combining physical energy and emissions data and economic data in the form of a Social Accounting Matrix (SAM) had to be compiled from various data sources, because energy and pollution accounts from the SEEA are not available for Ireland. We find that the reduction target for energy related CO2 emissions in Ireland of 25.8% compared to 1998 levels can be achieved with a carbon energy tax of 10-15 euros per tonne of CO2. Though fuel switching is important in meeting the target, this result is more sensitive to the possibilities for producers to substitute away from energy use. Welfare would fall but only by small percentages. Production and consumption patterns would change more significantly, with a shift in demand from fuels with a high emission factor to energy sources with a lower carbon-intensity and from energy to other commodities. This paper confirms that a carbon energy tax leads to greater emission reductions than an equivalent uniform energy tax. The latter has a stronger negative impact on the less polluting energy sectors whereas the carbon tax greatly stimulates the use of renewable energy and reduces the use of peat and coal. The new SAM, the model and the application to energy taxes contribute to a better informed debate on environmental policy in Ireland. 相似文献

This paper provides an empirical analysis of the relative impacts of various factors on CO2 emissions from production of goods and services in China during two consecutive periods of 1992–1997 and 1997–2002. Results
show that, on the positive side, level of final demand for goods and services was the main reason for the increase of production-source
CO2 emission, while structure of net export has similar positive effect during the first period of 1992–1997. On the negative
side, technology factors remains as the main factors reducing emissions. The level of net export played some role in the first
period, but the effects were seen in the second period from energy intensity, fuel mix and input mix. The results suggest
that economic structure be focused as an important factor for CO2 emission reduction, with construction and transport as two key industries to lower carbon emission. 相似文献

This study investigates the relationship between foreign direct investment (FDI), trade and industrial emissions in member countries of the Central American Free Trade Agreement–Dominican Republic (CAFTA-DR) between 1979 and 2010. Our model is based on extant literature about the Environmental Kuznets’ Curve framework. In this study, we consider sulphur dioxide (SO2), nitrogen oxides (NOx) and carbon dioxide (CO2) as our dependent variables. Our key independent variables are FDI and trade. Our study finds evidence that foreign investment and trade have had a negative impact on our selected emissions. However, our models also estimate turning points which are below the current GDP per capita values for all CAFTA-DR member countries. This is an encouraging trend in terms of the potential reduction in emissions in the region. 相似文献
