New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

When peat swamps are drained for agriculture, the peat begins to decompose, and is an enormous source of carbon emissions. Mha (20%) of the peatlands of Peninsular Malaysia, Sumatra and Borneo in 2010, surpassing the area of Belgium and causing an annual carbon emission from peat decomposition of 230–310 Mt CO 2 e.

Study finds plausibly high volumes of Canadian oil sands crudes in US refineries in 2025 would lead to modest increases in refinery CO2 emissions

Green Car Congress

An analysis of the US refining sector, based on linear programming (LP) modeling, finds that refining plausibly high volumes of Canadian oil sands crudes in US refineries in 2025 would lead to a modest increase in refinery CO 2 emissions (ranging between 5.4% to 9.3%) from a 2010 baseline, depending upon the supply scenario.

EIA Estimates 2.1% Growth in Fossil Fuel CO2 Emissions in US in 2010; Still Below 1999-2008 Levels

Green Car Congress

The US Energy Information Administration (EIA) estimates in the April 2010 release of its Short-Term Energy and Summer Fuels Outlook that CO 2 emissions from fossil fuels, which declined by 6.6% in 2010 and 1.1% EIA projects that world oil consumption will grow by 1.5 million barrels per day (bbl/d) in 2010 and 1.6

EIA: US energy-related CO2 fell by 2.8% in 2019, slightly below 2017 levels

Green Car Congress

US energy-related CO 2 emissions declined by 2.8% CO 2 emissions had increased by 2.9% Because of continuing trends in how much energy the US economy uses and how much CO 2 that energy use generates, energy-related CO 2 emissions in 2019 fell more than energy consumption, which declined by 0.9%
