These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions.
The study, set in Singapore, suggests that better air quality will bring about climate co-benefits in reducing electricity generation via lower household demand, and thus mitigating carbon emissions. This is important for policymakers when forecasting and influencing future emissions paths in the context of climate change.

Shipping emissions form a significant part of the commodity supply chain’s carbon footprint, particularly for those commodities reliant on the mass transport of low-grade ores and concentrates. In 2018, the IMO set out a vision to reduce the carbon intensity of international shipping by 40% by 2030, relative to 2008 levels.

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. California statewide GHG emissions dropped below the 2020 GHG Limit in 2016 and have remained below the 2020 GHG Limit since then.
However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The aim is to better understand and predict the extent and impact of urban air pollution on Earth’s atmosphere. HALO in-hangar in Taiwan.
A two-year study led by researchers at the University of Toronto has found large trucks to be the greatest contributors to black carbon emissions close to major roadways. The difference between emission levels across the sites was more correlated with the number of large trucks on the road rather than number of cars. —Greg Evans.
As levels of ozone and fine particulate pollution (PM 2.5 ) rise, more patients end up in the ER with breathing problems, according to the largest US study of air pollution and respiratory emergency room visits of patients of all ages. Overall the association was strongest for asthma among adults under 65. in children and 0.8%
A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Despite this, research on the environmental and health impacts of tire wear has been neglected in comparison to the research and innovations dedicated to tackling fuel emissions.

A new report by the UK’s Office for National Statistics (ONS) finds that greenhouse gas (GHG) emissions from road transport in the UK rose by 6% from 1990 to 2017. The increase—albeit lower than the increase in road traffic—highlights the significant challenge in reducing emissions from road transport, the report says.
Many countries regulate ozone because of the damage the pollutant does to plants and people. Since the 1990s, tighter controls on emissions of those ingredients have lessened ozone pollution in many European and US cities. The researchers think the harmful effects of surface ozone pollution are much less recognized.
