Ozone, the main component of smog, is a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. New research shows that ozone pollution damaged millions of tons of wheat, rice, soybean and cotton crops in India in 2005. Surface ozone pollution in India damaged 6 million metric tons (6.7
When action is taken on these classical pollutants—particulate matter (PM), ozone (O?), and carbon monoxide (CO)—it also has an impact on other damaging pollutants. In 2013, outdoor air pollution and particulate matter were classified as carcinogenic by WHO’s International Agency for Research on Cancer (IARC).
1,000 to 21,000) deaths due to changes in ozone concentrations. 900 to 11,000) ozone-related early deaths per year. 300 to 4,000) ozone-related premature mortalities per year. 2000 (90% CI: 0–4,000) early deaths from ozone, according to the study.

At 2:56 AM PST today, NASA’s Orbiting Carbon Observatory 2 (OCO-2) was successfully launched into orbit from Space Complex 2 West at California’s Vandenberg Air Force Base, riding on a two-stage Delta II 7320-10 launch vehicle. by Jack Rosebro. This measurement is unique like a fingerprint, and can be used for identification.
The California Air Resources Board (ARB) has issued its official Auction Notice for the California Cap-and-Trade Program Greenhouse Gas Allowance Auction on 19 February 2013—the second official auction. The February 2013 allowance auction will. The February 2013 auction will be conducted using an electronic, internet-based.
The California Energy Commission unanimously adopted the 2013-2014 Investment Plan Update to support the development and use of green vehicles and alternative fuels. 20 million for hydrogen fueling infrastructure. 20 million for hydrogen fueling infrastructure. Roughly 24 stations are built or in development. $15
The US Environmental Protection Agency (EPA) is issuing a proposed rule under the Clean Air Act (CAA) that would waive requirements beginning in 2013 for systems used at gas station pumps to capture potentially harmful gasoline vapors while refueling cars.

A 2013 assessment by WHO’s International Agency for Research on Cancer (IARC) concluded that outdoor air pollution is carcinogenic to humans, with the particulate matter component of air pollution most closely associated with increased cancer incidence, especially cancer of the lung. Ozone is a major factor in asthma morbidity and mortality.
million of Fiscal Year 2013 funds ( FTA-2014-001-TRI ) for the deployment of low- or no-emission (LoNo) transit buses. The program gives priority consideration to the deployment of buses with the lowest energy consumption and least harmful emissions, including direct carbon emissions. Of that amount, $21.6 7407(d)); or.
HFCs are synthetic gases that are used in a variety of applications, but mainly to replace ozone-depleting substances in aerosols, foams, refrigeration and air-conditioning. California is required to reduce HFC emissions 40% below 2013 levels by 2030 under Senate Bill 1383.
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.
US Congressman Scott Peters (CA-52) introduced the Super Pollutant Emissions Reduction Act (SUPER Act) of 2013, legislation aimed at combating short-lived climate pollutants, which are only somewhat addressed by disparate government programs.
California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. million metric tons between 2017 and 2018, the first such decline since 2013. Transportation emissions declined 1.5 tons per person to 10.7
The cap-and-trade joins a suite of other major climate program measures including standards for ultra-clean cars (Advanced Clean Cars, earlier post ), low-carbon fuels (Low Carbon Fuel Standard, earlier post ) and renewable electricity. Compliance obligations for greenhouse gas emissions begins 1 January 2013. Earlier post.)
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. Black carbon Climate Change Emissions'
The 2013 Scoping Plan update lays out the remaining steps to the 2020 limits set by AB 32. Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. Major transportation related policies already in place are: The Low Carbon Fuel Standard (LCFS).
while the carbon intensity of its economy declined by 4.5%. Emissions from transportation sources were relatively constant from 2002 through 2007, declined through 2013, then increased by 9.0 MMTCO 2 e (6%) from 2013 to 2017. These reductions have occurred while California’s economy has continued to grow. Source: ARB.
As with its predecessor legislation, the MAP-21 provides funding to areas in non-attainment or maintenance for ozone, carbon monoxide, and/or particulate matter. billion in CMAQ funding for each year of the authorization-2013 and 2014. The MAP-21 provides just over $2.2
CARB also adopted a new plan to curb destructive “super pollutants” including black carbon, fluorinated gases and methane. Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions. emissions by more than 20%. emissions by more than 20%.
Volatile organic compounds (VOC), which include hydrocarbons, are major air pollutants as well as precursors of harmful compounds such as tropospheric ozone and secondary organic aerosols. compounds containing 2-12 carbon atoms) are mainly produced by automobiles, a conclusion in line with previous findings. Chevaillier, A.
In the first, they found that when fuel prices drove residents of São Paulo, Brazil, to mostly switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20%. At the same time, nitric oxide and carbon monoxide concentrations tended to go up. Alberto Salvo, Joel Brito, Paulo Artaxo, and Franz M.
SLCPs include black carbon (soot), methane and hydrofluorocarbons (HFCs)—the fastest-growing source of GHG emissions in California and globally—which are used as refrigerants, aerosol propellants and insulation. Black carbon. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change.
In “Estimated Excess Morbidity and Mortality Caused by Air Pollution above ATS Recommended Standards, 2011-2013,” published online in the August edition of Annals of the American Thoracic Society , researchers report on the annual health benefits of meeting more protective standards recommended by the ATS for O 3 and PM 2.5. 201602-103AR.
They accounted for both CO 2 emissions and emissions of ozone precursors (NO x , VOC, CO) and aerosols (BC or black carbon, OC, SO 2 ) as well as cloud effects (aviation-induced cirrus clouds and contrails)—i.e., Results could be used directly for calculating carbon credits or offsets required for single trips.
Further, a 2013 review by Denier van der Gon et al. 2013 found that the ratio of non-exhaust to exhaust particles is strongly increasing in the last two decades, due to exhaust emission reductions. Non-exhaust PM factors include tire wear, brake wear, road surface wear and resuspension of road dust. Denier van der Gon, H.A.C.,
Researchers were able to track that data via a network of sensors around the Bay Area that monitor both CO2 and five critical air pollutants: carbon monoxide, nitrous oxides (NO and NO 2 ), ozone, and particulates (PM 2.5). The study was published this week in the journal Environmental Science & Technology.
exposure in urban areas will increase 50% by 2030, compared to 2013. Climate benefits in the near-term (estimated using a GWP-20) are more than three times as large given the rapid benefits that the control of black carbon provides. Baseline and Accelerated Policy timeline for light-duty vehicles. Chambliss et al. Click to enlarge.
The study found the potential for 1,500–2,000 Bering Strait transits in 2025, a three- to four-fold increase from 440 transits in 2013 (based on the medium-growth scenario). MARPOL Annex VI sets limits on NO x and SO x emissions from ship exhaust, and prohibits deliberate emissions of ozone-depleting substances. Source: ICCT.
