In this study, the Community Multi-scale Air Quality (CMAQ) model was applied to simulate potential benefits from future emission control with unchanged meteorology. Fourteen scenarios towards energy, residential, agriculture, industry, and open burning were simulated and the changes in ozone (O-3)...
Let's explore these questions by investigating international agreements that have been set in place to help protect the world's population. We will see historical and current trends in air quality to help us better understand if these policies have been effective. We also see future initiatives a...
national and regional authorities and through research. EU policies aim to reduce exposure to air pollution by reducing emissions and setting limits and attainable targets for air quality. At the end of 2013, the European Commission adopted a proposal for a “Clean Air” package, which included ...
A few studies have considered equity impacts of future decarbonization scenarios, mostly focusing on selected regions or specific policies. Li et al., focusing on California, apply an energy-economic optimization model and a chemical transport model (CTM) to evaluate low carbon energy scenarios in 2...
We apply the nested grid version of the Goddard Earth Observing System (GEOS) chemical transport model (GEOS-Chem) to assess 2000–2050 changes in O3 air quality and associated radiative forcing in China owing to future changes in emissions under the Representative Concentration Pathways (RCP2.6, ...
benefit humans and their health, wellbeing or productivity but also can impact processes and the environment, especially in critical or essential environments and manufacturing processes; brought to the forefront during the pandemic, is now seen as a necessary standard going forward into the ...
air quality but also with extreme air pollution events, which may have a disproportionate effect on human health, and are thus a focus of clean air policies. Critical research questions for the sci- entific community are thus related to whether such extremes may change in the future as a resu...
Past strict policies have demonstrated remarkable effectiveness in emission control and fine particulate matter (PM2.5) pollution mitigation; however, it is not clear what the continuous benefits of current policies are for the future. Here, we summarized China's currently implemented, released, and ...
Addressing the disparities inherent in environmental and health outcomes requires persistent and targeted efforts. As we move forward, future policies and incentive programs should take a comprehensive approach. Trucks, given their substantial emissions and frequent routes through DACs, pose a considerable ...
In fact, particulate matter constitutes one of the most challenging problems both for air quality and for climate change policies. In this context, this paper reviews the most recent results within the atmospheric aerosol sciences and the policy needs, which have driven much of the increase in ...
