A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. Older models don’t even have the emission-control features that newer ones do. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants.

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.

Circle areas are proportional to values for (A and B) climate change, (C and D) human health (values for population over age 30), and (E and F) agriculture. Black carbon, a product of burning fossil fuels or biomass such as wood or dung, can worsen a number of respiratory and cardiovascular diseases. Source: Shindell et al.

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.

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

Green Car Congress

The next round of UN climate negotiations begins in Cancun today. 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.”

ADB draft report says 3B Asians could become affluent by 2050; significant challenges

Green Car Congress

In the more optimistic Asian Century scenario, the region’s gross domestic product (GDP) would soar to $148 trillion and account for 51% of global output in 2050. The draft report compares the potential outcomes for Asia under two competing scenarios: the Asian Century and the Middle Income Trap. —Asia 2050.
