Biden sets 2030 net GHG reduction target for US of 50-52% below 2005 levels

Green Car Congress

US President Joe Biden announced a new target for the United States to achieve a 50-52% reduction from 2005 levels in economy-wide net greenhouse gas (GHG) emissions in 2030. In 2019, US greenhouse gas emissions totaled 6,558 million metric tons of carbon dioxide equivalents (MMT CO 2 Eq.), or 5,769 MMT CO 2 Eq. or 5,769 MMT CO 2 Eq.

IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

In a fairly bleak assessment of global progress towards low-carbon energy, the International Energy Agency (IEA) concluded that, despite a few bright spots such as the rapid expansion of renewable technologies and the growth of hybrid and EV sales, the progress is far below that required to achieve a 2 °C pathway—i.e., Source: IEA.

Study finds that worldwide SO2 emissions rose between 2000-2005 after decade of decline; China, shipping topped growth

Green Car Congress

The analysis by researchers in the US and Europe estimates anthropogenic global and regional sulfur dioxide emissions spanning the period 1850–2005 using a bottom-up mass balance method, calibrated to country-level inventory data. By 2005, China’s share of sulfur emissions came in at 28% of the global total, up from about 2% in 1950.

Perspective: The UN Approval Process for Carbon Offsets

Green Car Congress

Since 2005, when major greenhouse-gas emitters among the Kyoto signatories were issued caps on their emissions and permitted to buy credits to meet those caps, there has been more than $300 billion worth of carbon transactions. The approval process for carbon offsets has two goals. Donovan, CEO of Renergie, Inc. INTRODUCTION.

Berkeley Lab/U. Hawaii team provides direct experimental evidence for mechanism for PAH formation in combustion; cleaner fuels could result

Green Car Congress

Researchers at the Department of Energy’s Lawrence Berkeley National Lab (Berkeley Lab) and the University of Hawaii have provided direct experimental evidence for the validity of a proposed mechanism for the first step in the process that transforms gas-phase molecules into solid particles such as soot and other carbon-based compounds.
