Globalizing Air Pollution

Environmental taxation and regional inequality in China

第34届中国气象学会年会

作者： jintai lin Laboratory for Climate and Ocean-Atmosphere Studies Department of Atmospheric and Oceanic SciencesSchool of Physics Peking University

Recent studies have revealed the issue of globalizing air pollution through complex coupling of atmospheric transport（physical route） and economic trade（socioeconomic route）. Recognition of such globalizing air pollution has important implications for understanding the impacts of regional and global consumption（of goods and services） on air quality, public health, climate and the ecosystems. This talk will introduce the concept and mechanism of globalizing air pollution, evaluate its environmental consequences, and discuss its relevance to improving global collaboration on pollution mitigation.

In order to combat environmental pollution, China enacted the Environmental Protection Tax Law in early 2018. Yet the impacts of the environmental tax on individual regions with different socioeconomic statuses, which are crucial for social justice and public acceptance, remain unclear. Based on a MultiRegional Input-Output(MRIO) table and a nationally regulated tax payment calculation method, this study analyzes the distributional impacts of an environmental tax based upon province’s consumption from both inter-provincial and rural-urban aspects. The national tax revenue based on the current levy mechanism is estimated to be only one seventh of the economic loss from premature mortality caused by ambient particulate matter(PM2.5). The taxation may slightly alleviate urban-rural inequality but may not be helpful with reducing inter-provincial inequality. We further analyze two alternative levy mechanisms. If each province imposes taxes to products it consumes(rather than produces, as in the current mechanism), with the tax rate linearly dependent on its per capita consumption expenditure, this would moderately increase the national tax revenue and significantly reduce inter-provincial *** better compensate for the economic costs of air pollution and reduce regional inequality, it would be beneficial to increase the tax rate nationwide and implement a levy mechanism based on provincially differentiated levels of consumption and economic status.

Erratum to:Stratospheric Ozone-induced Cloud Radiative Effects on Antarctic Sea Ice

第34届中国气象学会年会

Reductions in the anthropogenic emissions in conjunction with warming climate impose competing impacts on ozone over the Europe. Here, we use long-term observations over the EMEP network and simulations using a global chemistry-climate model(ECHAM5/MESSy) to investigate the changes in annual and seasonal ozone over Europe during the 1995–2014 period. We find that there are contrasts in observed as well as modeled ozone trends between the 5th and 95 th percentile concentrations, both with enhanced trends during daytime than nighttime. While the 95 th percentile ozone shows a decreasing trend(0.9 ug/m/yr during the noon hours), in response to the reductions in European anthropogenic emissions, the 5th percentile ozone, in contrast, has continued to increase especially in daytime hours(0.3 ug/m/yr). ECHAM5/MESSy Atmospheric Chemistry(EMAC) model successfully captures the observed temporal variability and the contrast in trends of 95 th percentile and 5th percentile ozone. The observed trend contrast indicates different driving factors affecting the surface ozone changes for polluted and background conditions.

结合观测资料和数值模拟结果,基于GE 2.5 MW风机的功率曲线,分析1982—2006年中国大陆陆地上潜在风电量的年际变化。结果表明,Reg CM3模式风速、观测插值风速和两者平均风速对应的25年平均年潜在风电量分别为每年25,2.5和11 PWh,均超过中国2030年预期电力需求的20%(2 PWh)。三者年潜在风电量的相对标准差分别为3%,8%和5%,相对极差分别为15%,33%和23%,年际变化较大。由于风电和电力需求的季节性不匹配以及风电较大的年际变化,若仅依靠风电,在夏季容易出现电力缺口,意味着需要大量后备发电机组,这将提升发电总成本,降低风电减排效益。
