the final version of the proposed First Update to the ClimateChange Scoping Plan (First Update). Achieving our long-term climate goal and 2032 ozone standards will require a much deeper penetration of ZEVs into the fleet. The California Air Resources Board (ARB) has released. The draft version was released in February.

Our results will have a significant impact on our understanding of the oxidizing capacity of the atmosphere and have wide ranging implications for pollution and climatechange. Welz et al.

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.
The regulation becomes effective 1 January 2012; first auctions (for 2013 allowances) will be held in August and November, 2012. When the nation addresses the growing danger of climatechange, as I believe it must and will, California’s climate plan will serve as the model for a national program. business-as-usual.
The BAU scenario assumes no further implementing legislation to prevent additional climatechange and growing air pollution, other than what is in place for the base year 2005. Northern India and the Arabian Gulf region, on the other hand, will suffer a marked increase in ozone levels. Lelieveld (2012). Zimmermann, U.M.
Chlorofluorocarbons (CFCs)—commonly used in refrigerators and air conditioners—play a role in creating a hole in the ozone layer over Antarctica. Despite this, synthetic greenhouse gases (SGHGs) beyond the CFCs have received relatively little attention up to now.
NSF anticipates funding of $35,000,000 to $39,000,000 in FY 2012 and FY 2013, pending availability of funds, to be awarded to an estimated 7 to 12 projects. NSF said that is chose a time span of several decades because within this timeframe modeled climatechange responses appear to be insensitive to CO 2 forcing scenarios.

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.). Lack, Brian M. 1223447.
The regulation will cover 360 businesses representing 600 facilities and is divided into two broad phases: an initial phase beginning in 2012 that will include all major industrial sources along with utilities; and, a second phase that starts in 2015 and brings in distributors of transportation fuels, natural gas and other fuels.

While last year it appeared that the auto industry as a whole would shift to R-1234yf, in September 2012, Daimler said that internal testing had identified safety (flammability) issues under certain conditions, and that it would not use R-1234yf in its products. The current work following Daimler’s balk in September 2012 is the fourth.

Sources already subject to the 2012 NSPS requirements for VOC reductions that also would be covered by the proposed 2015 methane requirements would not have to install additional controls, because the controls to reduce VOCs reduce both pollutants. EPA required green completions for hydraulically fractured natural gas wells in its 2012 rules.
In addition to CO 2 , other compounds such as ozone (O 3 ) precursors (nitrogen oxides (NO x =NO+NO 2 ), carbon monoxide (CO), and volatile organic compounds (VOCs)) and aerosols such as black carbon (BC) and organic carbon (OC) are emitted by ships. 1 from shipping in 2007, corresponding to 3.3% 1 of the total ship emissions in 2007.
The percent of biodiesel and renewable diesel in the total diesel blend have shown a significant growth in recent years, going from 1% in 2012 to 18% in 2017. Biofuels such as ethanol, biodiesel, and renewable diesel can displace fossil fuels and reduce the amount of fossil-based CO 2 emissions released into the atmosphere.
power from renewable sources—wind, solar, geothermal, biomass or landfill gas, hydropower, and marine and hydrokinetic—for retail electricity suppliers beginning at 6% in 2012 and gradually rising to 25% in 2025 and continuing at that level through 2039. The draft establishes a Renewable Portfolio Standard—i.e., Industrial Energy Efficiency.
Starting in 2012, the program will cover electricity generation, including imports, and large industrial sources and processes with annual GHG emissions at or above 25,000 MTCO 2 e. The initial cap level in 2012 will be set at the level of emissions expected in 2012 from sources covered at the start of the program.
Life cycle inventories have typically been presented at global, national, or regional levels—sufficient for understanding global processes such as climatechange and fossil fuel depletion, but insufficient for the analysis of local processes such as air pollution, according to the researchers. —Tessum et al.

Organic aerosol (OA) in the atmosphere is detrimental to human health and represents a highly uncertain forcing of climatechange. The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone. Day, Lynn M.
SLCPs may account for an estimated 40% of global warming, increasing the impacts of climatechange. This aligns with the federal government’s current goal of reducing methane emissions from oil and gas operations by 40–45% below 2012 levels by 2025.
Circle areas are proportional to values for (A and B) climatechange, (C and D) human health (values for population over age 30), and (E and F) agriculture. Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. National benefits of the CH 4 plus BC measures versus the reference scenario.
A new report prepared by the World Bank at the request of the G8 identifies ways that the World Bank can do more through its projects to reduce the emission of short-lived climate pollutants (SLCPs): black carbon, methane, tropospheric ozone, and fluorinated gases known as HFCs. Over the six-year period of the review (FY2007-2012), 7.7
Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. California’s vehicle GHG standards—authorized by AB 1493 (Pavley) in 2002, first approved in 2004, and extended in 2012—are delivering fuel consumption and CO 2 reductions.
