New phase of globalization could undermine efforts to reduce CO2 emissions

Green Car Congress

A new study finds that the growth of carbon production from Chinese exports has slowed or reversed, reflecting a “new phase of globalization” between developing countries that could undermine international efforts to reduce emissions. The paper is published in Nature Communications.

AQLI: new data reveals little progress globally in reducing air pollution over the last two decades

Green Car Congress

With growth in coal consumption in Africa over the next two decades projected to be triple what it was in the past two decades, recognizing particulate pollution as a possible growing problem becomes even more important. High pollution across the entirety of Bangladesh makes it the most polluted country in the world.

UN Environment report says national GHG pledges only bring one-third of reductions needed for Paris Agreement

Green Car Congress

If the emissions gap is not closed by 2030, the report says, it is extremely unlikely that the goal of holding global warming to well below 2 ˚C can still be reached. In the current policy scenario, total emissions for transport are 9.7 GtCO 2 direct emissions and 0.28 GtCO 2 indirect emissions for electricity use.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C °F) by 2050, as well as improving human health and agriculture.

Low-lying and other vulnerable countries calling for fast action on non-CO2 global warming pollutants

Green Car Congress

Ramanathan and Victor highlight the importance of aggressively reducing CO 2 emissions, but note that the road ahead will be long, difficult, and expensive, and that “in the meantime, a fast-action plan is needed.” For example, reducing emissions from open cooking and diesel vehicles could save many of the 1.9

Study Finds Black Carbon a Significant Factor in Melting of Himalayan Glaciers

Green Car Congress

The main reason for the increase is the accelerated economic activity in India and China over the last 20 years; top sources of black carbon include shipping, vehicle emissions, coal burning and inefficient stoves. Black carbon’s effect on snow is not linear. It also contributes to the decrease in rainfall over central India.
