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

Green Car Congress

Low-sulfur gasoline standards and regulations on power plants have successfully cut sulfate concentrations in the air, reducing the fine particulate matter that harms human health and cleaning up the environmental hazard of acid rain. This makes conversion of sulfur dioxide to sulfate more efficient.

Greyrock, NREL study determines reduction in GHG and criteria pollutant emissions from using synthetic fuels produced from flare gas

Green Car Congress

A “well-to-wheel” life cycle assessment (LCA) by a team from synthetic fuels producer Greyrock ( earlier post ), and the National Renewable Energy Laboratory (NREL) has determined the potential reduction of greenhouse gases and criteria pollutant emissions from the use of synthetic fuels directly converted from flare gas. billion liters (18.8

GTI quantifies opportunity to produce low-carbon renewable natural gas (RNG) from wood wastes

Green Car Congress

New RNG production facilities using the commercial technologies outlined in the analysis could reduce criteria pollutants by approximately 99% compared to existing operational biomass power plants and produce a very low carbon fuel in the base case and below zero in the case including carbon sequestration technologies.

Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

When the temperature gets colder, they can actually go through the gas to particle conversion process, creating new particles and increasing the overall particle number concentration. This is important, especially in the relatively clean upper troposphere. The emission sources are limited up there. —Neil Donahue.
