2009), reproduced from Ramanathan and Feng (2008) Click to enlarge. The Montreal Protocol has already delayed climatechange by seven to 12 years, and put the ozone layer on the path to recovery later this century. The Montreal Protocol is critical for avoiding abrupt climatechange. From Molina et al. Ramanathan.
This article shows that including offsets in climatechange legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,
Despite the economic effects of the global financial crisis (GFC), carbon dioxide emissions from human activities rose 2% in 2008 to an all-time high of 1.3 between 2000 and 2008, compared with 1% per year in the 1990s. Emissions from coal are now the dominant fossil fuel emission source, surpassing 40 years of oil emission prevalence.
The FY 2011-2012 plan focused primarily on five areas of interest: sustainable communities; behavior and technology adoption; health and air pollution exposures; air pollution science; and greenhouse gas targets. These regulations have led to considerable improvements in air quality throughout California.
Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. Ozone is harmful to humans at ground-level, causing pulmonary and heart disease.
The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.

The International Maritime Organization, a United Nations agency responsible for regulating shipping, has set a global target to cut annual emissions by at least 50% by 2050 from 2008 levels. Fuel cells are widely considered as one of the most promising solutions for reducing harmful pollutants.
The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived ClimatePollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2.
signed SB 1383 , establishing the nation’s toughest restrictions on super pollutants including black carbon, fluorinated gases and methane. The law is in addition to California’s existing raft of climate legislation. Reducing these pollutants can have a more immediate beneficial impact on climatechange.
The first workshop, on 2 March, focused on preliminary elements of the proposed criteria pollutant emission standards and involved a presentation of technical information from several studies that are under evaluation for potential greenhouse gas emission reduction. Volkswagen, 2008. EDAG, 2009. Future Steel Vehicle: Phase I.
The opportunity for fuel cell-powered ships has accelerated in recent years, as the International Maritime Organization (IMO) set aggressive environmental targets to combat climatechange. A key objective for international shipping under the IMO’s mandate is to reduce greenhouse gas emissions by half compared to 2008 levels.
In the agreement, California and the Ministry commit to activities that will reduce air pollution while enabling sustained economic growth and increase cooperation to enhance pollution control strategies for industrial sectors and the transportation sector.
As a result of their findings, published in the 30 October issue of the journal Science , the authors argue that assessments of multigas mitigation policies, as well as any separate efforts to mitigate warming from short-lived pollutants, should include gas-aerosol interactions. Shindell et al. —Drew Shindell.
It found that 65% of respondents spontaneously selected emissions from road transport as a cause of climatechange. Most respondents said they think cars or aeroplanes are the transport modes mainly responsible for climatechanging emissions. In 2008, 64% agreed with that; in 2007, 63%; and in 2006, 62% agreed.
The proposed targets, required under SB 375 (2008, Steinberg), are designed to help coordinate land use and transportation planning. While the goal is to reduce greenhouse gases from passenger vehicles, it also helps clean the air in the state by reducing the amount of pollution that creates smog. Earlier post.).
The researchers believe the measurements will substantially impact the understanding of atmospheric chemistry mechanisms—in particular, in the more rapid formation of secondary aerosols, important in the formation of local smog as well as in global climatechange. Carl Percival. —Marston (2012). Welz et al.
Biodiesel blends became mandatory in early 2008, quickly followed by a raise in blend levels from 2 to 3% in July of the same year and from 3 to 4% in 2009. Local agencies now have 12 months to present Vehicle Pollution Control Plans targeting specific fleet groups, defining frequency and priority areas for inspection.
But in a year that has seen both a worsening recession and state budget crisis, residents’ support for urgent action on climatechange has slipped and a partisan divide on the issue has widened. Support has declined 7 points from July 2008 (73%) and 12 points from 2007 (78%). Mark Baldassare, president and CEO of PPIC.
Researchers from the Ontario Institute for Cancer Research (OICR), with colleagues at other institutions in Canada and the UK, have found strong evidence that environmental exposures, including air pollution, affect gene expressions associated with respiratory diseases much more than genetic ancestry. A permutation test ( n ?=?10,000
Verification of the emission reduction or carbon sequestration is critical in efforts to mitigate climatechange. One question is who will be responsible for verifying changes in carbon, which raises questions about the role of a regulatory agency for accrediting claimed changes in carbon levels from an activity.
Shipping is a major driver in the Australian economy, with 753 Mt of international exports worth $202 billion passing through Australian ports in 2008-2009. We know from previous studies and the Australian Pollutant Inventory that ship emissions off the coast of Australia are substantially larger than in-port ship emissions.
The number of EU countries with CO2-related car taxation rose to 15 in 2008. In most Central and Eastern European countries, the main concern of policy makers remains to reduce the level of old vehicles on the streets with pollutant emission standards of below Euro 3. ACEA provides an overview of the CO 2 -based vehicle taxes here.

The California Energy Commission has established an Alternative and Renewable Fuel and Vehicle Technology Program to develop and deploy advanced transportation technologies to help attain the state’s climatechange policies. Earlier post.)
Several states, local governments and environmental organizations had sued EPA over the agency’s failure to update the pollution standards for fossil fuel power plants and petroleum refineries, two of the largest source categories of GHG pollution in the United States. pollutants. pollutants separately, EPA said.
The next stage is to extend the energy supply concept to include fuel cells—which are characterized by high efficiency and pollution-free operation. If commercial shipping is to meet the IMO target, and seriously take on the challenge that the climatechange poses, large sections of it has to convert to much more sustainable solutions.
Chairman of the Homeland Security and Governmental Affairs Committee, released the details of their long-anticipated energy and climatechange legislation on Wednesday, 12 May. According to the recently finalized Inventory of US Greenhouse Gas Emissions and Sinks: 1990-2008 , net US GHG emissions in 2008 were down 2.7%
The cap-and-trade program also works in concert with other measures, such as standards for cleaner vehicles, low-carbon fuels, renewable electricity and energy efficiency, and complements and supports California’s existing efforts to reduce smog-forming and toxic air pollutants. ARB Staff presentation on Cap-and-Trade Program.
We’ve always planned on retiring and spending the rest of our lives right here, but these days we’re worried about what climatechange is already doing – and about the far more serious consequences headed our way. We’re already getting used to the fires, smoke and related air hazards here in the L.A.
The ocean absorbs CO 2 from the atmosphere at a rate of more than 20 million tons per day, thus removing one-fourth of the anthropogenic CO 2 emitted to the atmosphere each year and reducing the climate-change impacts of this greenhouse gas. However, when CO 2 dissolves in seawater, it forms carbonic acid. 2007; Tyrrell et al.,
Members of REVI will include San Diego County; the Cities of Carlsbad, Chula Vista, Coronado, Del Mar, Escondido, San Diego, and Solana Beach; and three regional public agencies including the San Diego County Regional Airport Authority, the San Diego Air Pollution Control District, and the San Diego Unified Port District.
Driving this innovation in technology, is a sincere commitment from BYD to provide safe and appealing solutions that reduce pollution from carbon emissions and address the issue of climatechange, supporting the initiative to Cool the Earth by 1?. The green dream has long been a priority for BYD and is the vision for the future.
CARB also adopted a new plan to curb destructive “super pollutants” including black carbon, fluorinated gases and methane. The plan, California’s Short-lived ClimatePollutant Reduction Strategy, maps out the route to more rapid greenhouse gas reductions by clamping down on these super pollutants.
Air pollution. Emissions of regulated air pollutants from vehicles continue to fall across EEA member countries but concentrations remain high in some urban areas.

According to the groups, SANDAG used a deficient process to develop a plan that will over-invests in freeways at the expense of public transit, increased pollution and exacerbated global climatechange. In 2008, California accounted for approximately 7% of US greenhouse gas emissions with a total of 473.66 Earlier post.)
The largest one-year emissions drop California has ever achieved was at the height of the Great Recession in 2009, when climatepollution fell 6.1%. lower than 2008 and 2003, respectively. Data from the report illustrate that California now must reduce emissions by an average of 4.9% lower and 8.3%
Reducing emissions in communities heavily burdened by pollution and environmental stressors. The core of the plan is made up of research initiatives, which consist of broad topics (Health, Environmental Justice, Economics, Air Quality, Mobile Sources, Climate and Sustainable Communities) defining CARB’s most pressing research priorities.
The project began in early 2008 and will conclude later this year. The gas is first cooled to condense and remove moisture and residual pollutants before it enters the CO 2 absorber. Testing at the pilot facility, using a 1.7-megawatt There, the CO 2 is absorbed by an ammonia-based solution, separating it from the flue gas.
In Torrance we don’t want citizens telling politicians what to do or controlling how the industries that pollute in own city act. That’s because what’s good enough for Manhattan Beach and Hermosa Beach isn’t good enough for Torrance. That’s too much democracy for Torrance. But of course, it shouldn’t be.
Issues covered in the briefing include emissions, air pollution, noise and renewable energy and the impact of transport on ecosystems and biodiversity. Oil consumption by the transport sector will need to fall by more than two-thirds to meet the objective of reducing consumption by 70% by 2050 compared with 2008 levels. Air pollution.
This new maize sequence provides significant refinements over the draft sequence that was announced in February 2008, including the elimination of redundancy and improvements in the ordering and orientation of chromosomal segments. New sequence of maize genome.
By sector, power plants were the largest source of emissions, accounting for 31% of total US greenhouse gas pollution. Starting in 2005, the rate of VMT growth slowed considerably (and declined rapidly in 2008) while average new vehicle fuel economy began to increase. ClimateChange Emissions' Source: EPA.
Additionally, including these fuels in the program provides a consistent price on GHG pollution throughout the economy and ensures a level playing field across all fuels and consumers.
