Increased relative contribution of medium and heavy trucks to U.S. greenhouse gas emissions

Green Car Congress

In this analysis, I examined recent changes in the contribution of transportation to total greenhouse gas emissions in the United States relative to the other sources of emissions (industry, commercial, residential, and agriculture). The analysis is an update of a study published in 2016. by Michael Sivak.

Emissions of potent GHG HFC-23 have grown, contradicting reports of huge reductions

Green Car Congress

Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. This gas has very few industrial applications. This would have been a big win for climate.

Global Carbon Project: Low growth in global carbon emissions continues for third successive year

Green Car Congress

Global carbon emissions from burning fossil fuels did not grow in 2015 and are projected to rise only slightly in 2016, marking three years of almost no growth, according to researchers at the University of East Anglia (UEA) and the Global Carbon Project. for 2016 marks a clear break from the rapid emissions growth of 2.3%

Global Mobility Report finds world not on track to achieving sustainable mobility

Green Car Congress

The GMR is the first study to assess the global performance of the transport sector and the progress made toward four main objectives: universal access, efficiency, safety, and green mobility. The GMR report focuses on two primary impacts: climate change and air and noise pollution. Non-Annex I countries averaged 4.8%

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

Green Car Congress

The presence of ammonia was first discovered in the upper troposphere in 2016 using the analysis of averaged MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) infrared limb-emission spectra. What we found is that the nitric acid and ammonia are susceptible to temperature changes.
