Synergistic control of carbon emissions and pollutant concentrations can efficiently tackle climate change air pollution. The synergistic performance co-benefits yielded by controlling these factors are urgent critical issues in China. Accordingly, a comprehensive indicator for assessing is pioneered, mitigating CO2 PM2.5 Chinese cities evaluated. dominated variations. In 2015–2020, multiple northeastern, central, southern, eastern exhibited effects greatly reducing emissions. thereafter leads to through environmental economic feedbacks. controls Northeast feature the most profound approximate 4800 CNY per capita, with each contributing 72 % 28 %, respectively, this total. findings provide intercity scientific support policymaking.

Plants play a crucial role in mitigating air pollution, which can be evaluated by examining their biochemical characteristics, including ascorbic acid, total chlorophyll content, pH, and relative water content. These traits provide valuable insights into plants’ capacity to counteract atmospheric pollutants. Moreover, combining pollution tolerance Suspended Particulate Matter (SPM) retention potentials could lead an adequate assessment of plant species for greenbelt development. This study assessed characteristics SPM potential six selected ( Ficus benghalensis L, religiosa Polyalthia longifolia (Sonn.) Thwaites, Azadirachta indica A.Juss, benjamina L , Bougainvillea glabra ) at polluted (Okhla Phase-2) non-polluted (Siri Fort) sites Delhi, India, during pre- post-monsoon. In addition, based on the Air Pollution Tolerance Index (APTI) has been calculated. Also, impact changes independent variables such as content APTI different was using linear regression. The found that A.indica exhibited highest 9.43 F.benghalensis lowest 8.3 maximum minimum recorded values adhesion leaves F. post-monsoon were 1305.46 g/cm 185.51 g/cm, respectively. Additionally, statistical analysis, regression coefficient (R = 0.93) observed between & with APTI, indicating substantial calculation these parameters. demonstrated plants elevated parameters, effectively reduce pollutants from atmosphere. findings highlight importance considering specific when selecting

Drivers and Decoupling Effects of PM2.5 Emissions in China: An Application of the Generalized Divisia Index

International Journal of Environmental Research and Public Health, Год журнала: 2023, Номер 20(2), С. 921 - 921

Опубликована: Янв. 4, 2023

Although economic growth brings abundant material wealth, it is also associated with serious PM2.5 pollution. Decoupling emissions from development important for China’s long-term sustainable development. In this paper, the generalized Divisia index method (GDIM) extended by introducing innovation indicators to investigate main drivers of pollution in China and its four subregions 2008 2017. Afterwards, a GDIM-based decoupling developed examine states between identify factors leading decoupling. The obtained results show that: (1) Innovation input scale GDP are increases emissions, while intensity, emission coefficient reasons reductions (2) general upward trends index, their turn weak strong (3) contribute largely emissions. Overall, paper provides valuable information mitigating haze
