Recycling carbon tax revenue is a significant part of the design of a nation's carbon tax system. The impact of different recycling principles on the socio-economy and carbon emission reduction varies greatly. Under the background of China's goal of reaching peak carbon emissions, this paper designed three carbon tax recycling principles based on the goal of Nationally Determined Contributions (NDCs), including recycling principles based on output ratio, export ratio, and carbon intensity. A recursively dynamic CGE model was developed in this study to evaluate the economic effects of these three carbon tax recycling principles based on tax neutrality under China's goal of reaching peak carbon emissions. Carbon tax recycling measures could mitigate the economic losses caused by carbon tax, and the results could be greatly affected according to different recycling principles. The results showed that: 1 The recycling principle based on output ratio could reduce economic losses and improve households' social welfare. 2 China's carbon intensity in 2030 could be reduced by more than 65% compared with that in 2005, and the proportion of non-fossil energy in primary energy consumption could reach 25% using the recycling principle based on carbon intensity, but the economic loss mitigation effect of the recycling measures based on this principle was small. 3 Adopting the recycling principle based on export ratio would narrow the competitive gap between China and foreign countries, and the exports of high-carbon-intensity goods would not increase under this principle. 4 According to principles based on output ratio and export ratio, the NDC goal of non-fossil energy accounting for about 25% of primary energy consumption by 2030 could not be achieved, and only the NDC goal of reducing carbon emissions per unit of GDP by more than 65% compared with that of 2005 could be achieved. In brief, as an essential policy tool to achieve China's goal of reaching peak carbon emissions, the carbon tax should be implemented as soon as possible. At the same time, according to China's national conditions, a targeted choice of carbon tax recycling principle is needed. The role of the carbon tax in the process of achieving the goal of Nationally Determined Contributions should be fully utilized. [ABSTRACT FROM AUTHOR]

This study examines the impact of meeting China's Paris Climate Agreement commitment to reduce its emission intensity by 65 % below 2005 levels by 2030 through various policy instruments. We use a dynamic recursive computable general equilibrium model to simulate the economy-wide impacts of administrative mandates and carbon taxes using different revenue recycling schemes. China's GDP in 2030 would be approximately 1 % lower than the baseline if carbon emissions were constrained by mandates. The commitment's economic costs are lower than the carbon constraint case, regardless of revenue recycling. Economic costs are the lowest when carbon tax revenue is recycled to reduce taxes on capital or corporate income. Subsidizing solar and wind energy further reduces emissions, but at a higher economic cost with a GDP loss of about 0.53 %–0.58 % from the baseline. The results highlight the importance of proper design architecture to make carbon taxes more palatable to policymakers and taxpayers. [Display omitted] [ABSTRACT FROM AUTHOR]

The carbon tax, as one of the environmental regulation tools, is likely to promote technological progress, which is ignored in previous works when evaluating the economic impact of a carbon tax. This study uses the Generalized Method of Moment model to investigate the effect of an environmental tax on total factor productivity and energy efficiency, and takes the effects as approximations of the effects of carbon tax on technological progress into the computable general equilibrium model as well as considering technology diffusion, to analyze the dynamic impact of carbon tax on China's economy growth. A carbon tax policy negatively impacts GDP at the early stage, but technological progress would make GDP impacts "turn negative into positive" in the late stage. With a carbon tax rate of 100 Yuan/ton, the GDP impact becomes positive from the 4th year and rises to 0.3% in 2030. Not all industries can realize the output of "turning negative into positive," only low-carbon-intensity industries can achieve a clean transition. Overall, this study discusses the dual effects of a carbon tax on technological progress and increasing fossil energy costs, which provides a new perspective for an in-depth discussion of a carbon tax.
