How effective are carbon trading schemes in reducing greenhouse gas emissions?4 answersCarbon trading schemes have shown effectiveness in reducing greenhouse gas emissions, particularly in the power industry and industrial sectors. Studies have indicated that the adoption of Emission Trading Schemes (ETS) has led to significant reductions in carbon emissions. ETS adoption has been found to induce reductions in CO2 emissions, optimize energy structures, and promote technological innovation, contributing to lower emission intensities. The schemes have been particularly successful in promoting green development in backward power plants and optimizing industrial structures, leading to regional reductions in industrial carbon emissions. Additionally, ETS has been effective in reducing total carbon emissions, mainly through decreased coal consumption and improved energy structures, with positive spatial spillover effects on non-pilot regions.
How has the implementation of the Paris Agreement impacted the global reduction of greenhouse gas emissions?4 answersThe implementation of the Paris Agreement has had varying impacts on global greenhouse gas emissions reduction. The Agreement, based on voluntary contributions and the principle of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC), aims to align financial flows with low greenhouse gas emissions pathways. While the Agreement is considered more equitable and feasible than previous climate agreements, studies show mixed results on its effectiveness. Research indicates that the Paris Agreement has led to a modest reduction in CO2 emissions, albeit less than anticipated. Additionally, the choice of greenhouse gas metrics, such as GWP100, plays a crucial role in determining cost-effective mitigation strategies under different temperature overshoot scenarios. Overall, the Agreement's impact on global emissions reduction is influenced by member states' compliance, financial investments, and the evolving nature of climate governance.
How effective is a carbon tax in reducing emissions?4 answersA carbon tax is an effective policy tool for reducing emissions. Studies have shown that the introduction of a carbon tax led to a significant decline in emissions in the British power sector, with the tax explaining around 60% of the total emissions reduction. Additionally, carbon taxes can help countries achieve their climate mitigation goals with little economic disruption, as seen in the case of the United States where a carbon tax could achieve a 26% reduction in carbon emissions with a minimal negative effect on GDP. Furthermore, a dynamic CGE model constructed for China demonstrated that a combination of gradually increasing the carbon tax rate and lowering the resource tax rate can effectively reduce economic losses, achieve a carbon peak, and promote the joint development of the environment and economy. These findings suggest that carbon pricing, such as a carbon tax, should be viewed as a viable policy option for abating emissions at moderate costs.
