ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. —Pavlenko et al.

Study links PM2.5 pollution with millions of preterm births globally

Green Car Congress

Environment International. Recent research has suggested that exposure to air pollution could also be a risk factor. exposures, inclusion of provider-initiated preterm births, and exposure to indoor air pollution. The open-access study is published in the journal. associated preterm births in 2010 for 183 countries.

China study connects ozone pollution to cardiovascular health

Green Car Congress

The study, by a team from Duke University, Tsinghua University, Duke Kunshan University and Peking University, appears in the journal JAMA Internal Medicine. They monitored indoor and outdoor ozone levels, along with other pollutants. In contrast, only 31 million Americans live in counties where other pollutants exceed EPA standards.

EPA proposes first US greenhouse gas emissions standards for aircraft

Green Car Congress

This proposed action would align US standards with the international CO 2 emissions standards adopted by the International Civil Aviation Organization (ICAO) in 2017, making domestically manufactured aircraft competitive in the global marketplace. The new action begins the process of following through on that requirement.

Study shows alkanes can rapidly acquire oxygen atoms in a free radical chain reaction; significant for fuel combustion and air pollution

Green Car Congress

An international team of researchers has shown that alkanes participate extensively in autoxidation reactions with oxygen molecules. These findings enrich our understanding of autoxidation processes and will allow us to better perform predictive simulations of combustion engines and atmospheric processes that impact air quality and climate.
