Study finds coal trains add significant amount of PM2.5 pollution in urban areas

Green Car Congress

Coal trains and terminal operations add a significant amount of fine particulate matter (PM 2.5 ) pollution to urban areas—more so than other freight or passenger trains— according to a study conducted in Richmond, California, by the University of California, Davis. million deaths per year globally.

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. A study by Mark Z.

EPA proposes new pollution standards for fossil fuel-fired power plants

Green Car Congress

EPA says that the proposed limits and guidelines would require ambitious reductions in carbon pollution based on proven and cost-effective control technologies that can be applied directly to power plants. They also provide owners and operators of power plants with lead time and compliance flexibilities.

ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

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. The Imperial researchers say that the effect of new technologies on the generation and impact of tire wear should be a priority. Scale bar of 10 μm = 0.01

Researchers use satellite data to show vehicles are an under-recognized source of urban ammonia pollution

Green Car Congress

Researchers now report in ACS’ Environmental Science & Technology Letters that satellite data from before and during the spring 2020 lockdown in Los Angeles shows that vehicles, rather than agriculture, are the main source of urban airborne ammonia (NH 3 ), which forms small particles that contribute to air pollution and harm human health.

SwRI engineers develop near-zero emissions diesel engine technology; 90% reduction of NOx

Green Car Congress

Southwest Research Institute engineers have developed the next generation of clean diesel engine technology to reduce hazardous nitrogen oxides (NO x ) and carbon dioxide emissions while minimizing fuel consumption. SwRI developed the technology for the California Air Resources Board (CARB). g/hp-hr NO x emissions).
