California policy makers face challenges in devising a pathway that can simultaneously help the state achieve NO x and GHG reduction targets. Background. grams per brake horsepower-hour (g/bhp-hr).
The California Air Resources Board on Thursday adopted the final greenhouse gas (GHG) emissions cap-and-trade regulation. Cap-and-trade is another important building block in California’s effort to create a clean and vibrant economy. the destruction of existing stores of ozone-depleting substances in the U.S. Earlier post.)
The California Air Resources Board is accepting applications for the 2014 Haagen-Smit Clean Air Awards. The awards are annually bestowed upon scientists, policy makers, community leaders and educators who have made outstanding contributions to the advancement of clean air and climatechange science, technology and policy.
The California Air Resources Board (ARB) is soliciting research suggestions for the Fiscal Year 2012-2013 Annual Research Plan in the form of brief conceptual descriptions that address specified research gaps and support the Board’s ongoing regulatory and policy priorities. The deadline to submit research concepts is 31 January 2012.
Researchers at the University of California, Irvine and other institutions have conducted a statistical analysis of pollution exposure and yields from 1980 to 2015 on a key sector making up about 38% of the state’s total agricultural output: perennial crops such as almonds, grapes, nectarines, peaches, strawberries and walnuts.
On the first day of a two-day board meeting—the second day of which (Friday 24 March) will consider the Advanced Clean Cars Midterm Review—the California Air Resources Board (ARB) took a number of climate and air quality actions. emissions by more than 20%. emissions by more than 20%.
The California Air Resources Board’s latest state inventory of greenhouse gas emissions shows that California’s GHG emissions continue to decrease. These reductions have occurred while California’s economy has continued to grow. Compared to 2016, California’s GDP grew 3.6% Trends in California GHG Emissions.
For its part, EPA is withdrawing the Clean Air Act preemption waiver it granted to the State of California in January 2013 as it relates to California’s GHG and ZEV programs. California’s ability to enforce its Low Emission Vehicle program and other clean air standards to address harmful smog-forming vehicle emissions—i.e.,
Although viewed as a potential target in the global effort to reduce climatechange, atmospheric black carbon particles absorb significantly less sunlight than scientists have predicted, according to a new study by an international team of researchers, published in the journal Science. Earlier post.).
The bill also directs the President to work with the relevant Federal agencies and California to harmonize, to the maximum extent possible, the federal fuel economy standards, any emission standards promulgated by EPA, and the California standards for light-duty vehicles. trucks, construction machines, ships and planes.
The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climatechange. Black carbon.

The United States and California state averages shown are based on total on- and off-road use. The urban areas in California shown are for on-road fuel use only. Organic aerosol (OA) in the atmosphere is detrimental to human health and represents a highly uncertain forcing of climatechange. Gentner et al. Earlier post.).
A new report released by the California Air Resources Board (ARB) has sent a stark warning on the effects of climatechange on ozone levels in the state’s major air basins.
The instrument, which was designed by Hamilton Sunstrand and built by the California Institute of Technology’s Jet Propulsion Laboratory (JPL), is almost identical to the original Orbiting Carbon Observatory (OCO) Earth Science mission instrument, ( earlier post ), which launched on 24 February 2009 aboard a Taurus launch vehicle.
The study, by a team of researchers from Carnegie Mellon University, University of Georgia, Aerodyne Research, California Air Resources Board (ARB), Ohio State University, UC Berkeley, and UC San Diego is published in the ACS journal Environmental Science & Technology. We estimate ozone and SOA formation potential. —Saliba et al.
In a new study published online 10 March in the ACS journal Environmental Science and Technology , however, Stanford University professor Mark Jacobson finds that local CO 2 emissions in isolation may increase local ozone and particulate matter. Although the health impacts of such changes are uncertain, he notes, they are of concern.
The California Air Resources Board announced $3.7 Rebates are available to individuals, business owners and government entities in California that purchase or lease new eligible zero-emission or plug-in hybrid electric light-duty vehicles now. million in rebates for plug-in hybrid and zero emissions vehicles as part of an overall $42.3
The California Air Resources Board released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. California’s zero emission vehicle (ZEV) regulation is also driving a transformation of the fleet.
The studies use case studies to demonstrate the co-benefits of tackling climatechange in four sectors: electricity generation, household energy use, transportation, and food and agriculture. Climatechange threatens us all, but its impact will likely be greatest on the poorest communities in every country.

F, with about 40% due to ozone. The second study found that local CO 2 emissions produce CO 2 domes over cities, which increase local ozone and PM, increasing local mortality. The study found that CO 2 domes increase air pollution deaths by 50-100 per year in California, with most occurring in Los Angeles.
