In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. Over the course of five years, PM 2.5 But the rapid reduction of PM 2.5
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
In China, people breathe ozone-laden air two to six times more often than people in the United States, Europe, Japan, or South Korea, according to a new international study published in Environmental Science & Technology Letters. 2017 for one ozone metric. For China, sites in 74 major cities with continuous observations from 2013?2017
The California Energy Commission unanimously adopted the 2013-2014 Investment Plan Update to support the development and use of green vehicles and alternative fuels. Funding priorities through the ARFVT Program support fuel and vehicle development to help attain the state’s climate change policies. million ZEVs on the state’s roads.
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 US National Science Foundation has issued a solicitation for Decadal and Regional Climate Prediction using Earth System Models (EaSM). 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 EaSM solicitation.
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 (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 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.
GWP100 weighted specific climate impact (g CO 2 -eq per pkm) as a function of vehicle occupancy. A team from Austria and Norway has found that the climate impact from a long-distance trip (500–1,000 km, or 310–621 miles) can easily vary by a factor of 10 per passenger depending on mode choice, vehicle efficiency, and occupancy.
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.
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.)
SAS involves dozens of other domestic and international research institutions, and is one of the largest North American air quality and climate studies in decades. The field phase for the SAS began 1 June 2013 and runs through 15 July 2013 and is generally focused in the southeastern United States. Climate Change Emissions'
million metric tons between 2017 and 2018, the first such decline since 2013. in 2018 (2000-2018 average year-over-year increase is 6.8%), continuing the increasing trend as they replace Ozone Depleting Substances (ODS) being phased out under the 1987 Montreal Protocol. Transportation emissions declined 1.5 tons per person to 10.7
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. The California waiver authority exists because California has uniquely difficult problems with ozone-forming pollutants.
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. It does not include emissions from petroleum refineries and oil production. Source: ARB.
psi RVP in southern ozone non-attainment areas—but allows a 1 psi RVP waiver for E10. Thus, the evaporative emission increase caused by E30 would then be less than for E10. Currently, the Clean Air Act limits the volatility of gasoline to 9.0 psi RVP and 7.8 This waiver applies only to E10 (E9-E10), not more, not less.).
The Afternoon Constellation, so named because it crosses the equator at approximately 1:30 PM local time every day, consists of five existing satellites in tight formation, collecting simultaneous data on aerosols, clouds, cloud ice, carbon sinks, carbon sources, ozone, particulates, and atmospheric water vapor.
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 climate change. —“Revised Proposed Short-Lived Climate Pollutant Reduction Strategy”.
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. 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'
New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. When action is taken on these classical pollutants—particulate matter (PM), ozone (O?), and PM 10 ), ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide.
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. Background. In 2014, ARB will propose enhancements to strengthen the LCFS.
exposure in urban areas will increase 50% by 2030, compared to 2013. Furthermore, this would also deliver a net annual reduction of at least 200 MtCO 2 e from short-lived climate pollutants in 2030 (using GWP-100 values). The climate benefits are 3.5 Baseline and Accelerated Policy timeline for light-duty vehicles.
Depletion of Antarctic ozone is a more important factor than increasing greenhouse gases in shifting the Southern Hemisphere jet stream in a southward direction, according to researchers at Penn State. Understanding the differences between these two forcings is important in predicting what will happen as the ozone hole recovers.
