Ice core data show why air pollution is dropping more slowly in US and Western Europe despite lower sulfur emissions

Green Car Congress

Despite these successes, sulfate levels in the atmosphere have declined more slowly than sulfur dioxide emissions, especially in wintertime. This unexpected phenomenon suggests sulfur dioxide emission reductions are less efficient than expected for cutting sulfate aerosols. These trends are expected to continue.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

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.
