Study finds 1.4 Gt discrepancy between national and provincial data sets for greenhouse gas emissions in China

Green Car Congress

The gap, noted the researchers in their open-access paper in Nature Climate Change , is equivalent to Japan’s annual CO 2 emissions, the world’s fourth largest emitter, with 5% of the global total. The dashed line represents the aggregated CO2 emissions calculated from the provincial energy statistics 1997–2010.

New study puts air-pollution related deaths in India in 2019 at 1.67 million

Green Car Congress

It increases future risk for heart disease, diabetes, and respiratory disease for today’s children when they become adults. These increases in deaths from ambient air pollution reflect increasing emissions from cars, trucks, and buses, as well as the widespread use of coal to generate electricity in India. It is reducing children’s IQ.

PBL/JRC: Global CO2 emissions increase to new all-time record in 2013, but growth is slowing down

Green Car Congress

The report is based on recent results from the joint JRC/PBL Emissions Database for Global Atmospheric Research (EDGAR), the latest statistics on energy use and various other activities. According to national statistics, in 2013 total oil consumption in transport increased somewhat by 0.5%, relative to 2012 levels. billion tonnes (Gt).

Argonne study finds shale gas GHG lifecycle emissions 6% lower than natural gas, 23% lower than gasoline and 33% lower than coal; upstream methane leakage a key contributor

Green Car Congress

The base results from a study by a team at the Center for Transportation Research, Argonne National Laboratory indicate that shale gas life-cycle greenhouse gas (GHG) emissions are 6% lower than conventional natural gas, 23% lower than gasoline, and 33% lower than coal. However, the environmental impacts (e.g., —Burnham et al.

MIT researchers build model simulating atmospheric transport of PAHs; how chemicals get to the Arctic

Green Car Congress

Selin and Friedman use the global 3-D chemical transport model GEOS-Chem to track the day-to-day transport of PAHs—toxic byproducts of burning wood, coal, oil and other forms of energy that remain in the atmosphere for less time than other persistent organic pollutants regulated by global standards.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. Increased use of coal relative to other energy sources has reversed the long?standing WG III Summary for Policymakers.

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

These gases come from human activities such as combustion of coal and oil as well as natural sources such as emissions from plants. Warmer temperatures and other changes in the atmosphere related to a changing climate, including higher atmospheric levels of methane, spur the chemical reactions that lead to ozone.
