Trends in the sizes and carbonaceous fractions of primary emitted particulate matter in China from 1960 to 2019

National Science Review, Journal Year: 2025, Volume and Issue: 12(3)

Published: Jan. 16, 2025

ABSTRACT The health impacts of particulate matter (PM) depend on its concentration, size and composition. Herein, we quantified the changes in emissions primary PM2.5, PM2.5–10 PM>10 with aerodynamic diameters <2.5 μm, 2.5–10 μm >10 respectively, black carbon (BC), organic (OC) to address driving factors. temporal trends PM follow Kuznets curves, 1995 as peak year when gross domestic product per capita was only US$1023, showing a late-mover advantage. fractions PM2.5 : BC OC non-carbonaceous-PM2.5 from various sectors varied following different trajectories. mass iron–steel production industries changed 21% 12% 67% 1960 50% 13% 37% 2019, decrease size. were linearly correlated whereas dependence differed before after 1995, owing residential emissions. Various factors influencing carbonaceous fraction explored. major promotion dust-removal capacity transition energy solid fuels emission-free fuels, which increased fine fraction.

Promoting the Achievement of Carbon Neutrality Targets: Systematic Review of Research Dimensions and Measure Methods on Carbon Equity in China

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(23), P. 9912 - 9924

Published: May 30, 2024

Carbon equity is the balance between carbon reduction responsibilities and development rights. The review of in China can help it achieve neutrality targets provide valuable insights to other emerging countries. This study aimed systematically sort, classify, compare, prospect research dimensions measure methods for equity. were first classified into intergenerational, regional, trade, income by literature analysis. Intergenerational explores emission rights among generations using integrated assessment models (IAM). Regional analyzes socioeconomic effect regional allocation IAM or differences under a specific assumption Theil index. Trade studies relationship emissions economic benefit transfer embodied inter-regional which more suitable calculating with comparable results, such as optimized environmental inequality Income investigates footprint heterogeneity groups Gini coefficient. paper further discusses potential directions each dimension. Notably, all did not consider promoted strategies equity, should be priority future studies.

The costs, health and economic impact of air pollution control strategies: a systematic review

Global Health Research and Policy, Journal Year: 2024, Volume and Issue: 9(1)

Published: Aug. 21, 2024

Air pollution poses a significant threat to global public health. While broad mitigation policies exist, an understanding of the economic consequences, both in terms health benefits and costs, remains lacking. This study systematically reviewed existing implications air control strategies worldwide.

Revealing Inter-regional Environmental Inequities Hidden in China’s Energy Transition

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(32), P. 11852 - 11862

Published: Aug. 1, 2023

Energy transition is an important way to control air pollution, but it may conflict with the economic goal of alleviating regional inequality due its inherently different cost burdens. As one effective measures energy transition, this paper takes small coal-fired boiler (SCB) upgrading as example explore mismatch between costs and health benefits. Here, we construct a boiler-level inventory SCB upgrades for North China Plain (NCP) during 2013–2017 propose integrated modeling framework quantify spatial contribution benefits associated upgrading. We find that although total could offset entire region, developed municipalities (Beijing Tianjin) are likely gain more from less-developed neighboring provinces at lower costs. These contribute only 14% 21% within their territories, 56% which come provinces. Their approximately 5.6 times costs, much higher than 1.5 benefit–cost ratio in Our findings be useful shaping equitable sound environmental policies or other regions world serious coal-related pollution.
