T&E study finds plug-in hybrids show higher CO2 emissions than claimed

Green Car Congress

Our tests show that even in optimal conditions, with a full battery, the cars pollute more than advertised. Selling plug-in hybrids makes it easier for carmakers to meet their EU car CO2 standards as PHEVs are currently given additional credits. Unless you drive them softly, carbon emissions can go off the charts.

Study: countries seeking to cut CO2 emissions must get a handle on city-level emissions

Green Car Congress

Countries seeking to meet Paris Agreement targets on CO 2 emissions must get a grip on the amount of pollution produced at city level, according to a new open-access study published in S cience Advances by an international team of researchers from Europe and China. —Prof Guan. —Prof Guan.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

Noting the references in scientific and policy literature to the need for fast-action mitigation to help avoid DAI and abrupt climate changes, the authors define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’s climate impact. The large uncertainty derives principally from the indirect climate-forcing effects.

Study: expanding Brazilian sugarcane for ethanol could reduce global CO2 emissions by up to 5.6%

Green Car Congress

Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global CO 2 emissions by as much as 5.6%, according to a new study by an international team led by researchers from the University of Illinois. The carbon-related costs of converting the land to sugarcane fields were included in the analysis.

GTI quantifies opportunity to produce low-carbon renewable natural gas (RNG) from wood wastes

Green Car Congress

New RNG production facilities using the commercial technologies outlined in the analysis could reduce criteria pollutants by approximately 99% compared to existing operational biomass power plants and produce a very low carbon fuel in the base case and below zero in the case including carbon sequestration technologies.

US and China jointly announce GHG reduction targets; US to cut net GHG 26-28% by 2025, China to peak CO2 by ~2030

Green Car Congress

The Administration said that the ambitious target is grounded in analysis of cost-effective carbon pollution reductions achievable under existing law and will keep the United States on a trajectory to achieve deep economy-wide reductions on the order of 80% by 2050. million cubic meters of freshwater per year.
