MIT study finds air quality co-benefits of US carbon policies can significantly offset costs, depending upon the policy

Green Car Congress

The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. times the cost of implementing a cap-and-trade program.

UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). The contribution of HFCs to climate forcing is currently less than 1% of all greenhouse gases.

California ARB greenlights states GHG cap-and-trade program

Green Car Congress

The program is designed to provide covered entities the flexibility to seek out and implement the lowest-cost options to reduce emissions. Each year, the total number of allowances issued in the state drops, requiring companies to find the most cost-effective and efficient approaches to reducing their emissions.

Report argues advanced HD natural gas vehicles foundational for California to hit air and climate goals; near zero-emission potential

Green Car Congress

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.

ARB releases proposed cap-and-trade regulation for comment; transportation fuels impacted in 2015

Green Car Congress

The cap-and-trade program gives sources flexibility to make the most cost-effective choices about when and how to reduce emissions. Because the allowances can be traded, the program provides incentives for those with the most cost-effective reduction opportunities to reduce emissions quickly. Cost Containment Mechanisms.

The new non-erosive structure cost about $400,000. In February 2008, GRF became one of the first forests—and the largest—to receive verification as a source of greenhouse gas reductions under the protocols of the Climate Action Reserve , adopted by the California Air Resources Board in 2007. ozone depletion potential (ODP).
