The New Mexico Environmental Improvement Board (EIB) and the Albuquerque-Bernalillo County Air Quality Control Board (AQCB) have each adopted the Clean Car Rule after a joint public hearing. Their independent approval of the Clean Car Rule allows California’s Advanced Clean Cars to be implemented statewide in New Mexico beginning 1 July 2022.
and ozone at or above the current standards have been linked to neuroinflammation and high risk of Alzheimer’s disease (AD). suggesting long-term exposure to PM 2.5 , as well as ozone above the current US EPA standards, are associated with increased risk of Alzheimer’s disease. Exposures to concentrations of PM 2.5 g/m 3 in PM 2.5
The European Parliament is calling for fast action to reduce non-CO 2 climate forcers including black carbon soot, hydrofluorocarbons (HFCs), methane, and ground-level ozone, which together are responsible for nearly half of climate forcing. Even cutting CO 2 emissions to zero today will not produce cooling for a thousand years.
A global phase down of HFCs could potentially reduce some 90 gigatons of CO 2 equivalent by 2050, equal to roughly two years worth of current global greenhouse gas emissions. While they do not deplete the ozone layer, many are highly potent greenhouse gases.
The US, Canada, and Mexico have submitted a proposal to strengthen climate protection under the Montreal Protocol— the international treaty that phases out the production of a number of substances responsible for ozone depletion. The proposal targets the production and use of HFCs, a group of “super” greenhouse gases. Click to enlarge.
This was agreed by: Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Korea, Mexico, Russia, Saudi Arabia, South Africa, Turkey,the United Kingdom, the United States, and the European Union, as well as Ethiopia, Spain, Senegal, Brunei, Kazakhstan, and Singapore.
Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot. Ramanathan and Victor highlight the importance of aggressively reducing CO 2 emissions, but note that the road ahead will be long, difficult, and expensive, and that “in the meantime, a fast-action plan is needed.”
positive or negative—and magnitude of net climate forcing from BC emissions), currently available scientific and technical information provides a strong foundation for making mitigation decisions to achieve lasting benefits for public health, the environment, and climate. emissions in 2005.

From 2005 through 2020, total US greenhouse gas (GHG) emissions are projected to rise by 4% under a “with measures” scenario (but without a cap-and-trade program and other complementary policies), from 7,109 Tg CO 2 Eq. The report projects that transportation-related CO 2 emissions will drop 1.5% to 7,416 Tg CO 2 Eq., 5,813 Tg CO 2 Eq.
HFCs are chemicals are potential substitutes for ozone-depleting and climate-warming CFCs and HCFCs currently being phased out under the Montreal Protocol treaty to protect the ozone layer. The United States, Mexico, and Canada also proposed a similar amendment. The Joint Task Force will submit its report by 1 August 2011.
The “cap”—which declines each year—limits GHG emissions, and uses allowances to control total emissions; one allowance equals one ton of GHGs. The “cap”—which declines each year—limits GHG emissions, and uses allowances to control total emissions; one allowance equals one ton of GHGs.
Scientists report in an open access paper this week in the journal Proceedings of the National Academy of Sciences (PNAS) that river and stream networks are the source of at least 10% of human-caused nitrous oxide emissions to the atmosphere. This new global emission estimate is startling.
Mayor of Paris and Chair of C40 Cities Anne Hidalgo and Mayor of London Sadiq Khan announced they are working together to create schemes to score new cars based on their real-world emissions and their impact on air quality and to provide that data in an accurate and accessible form to the public.

The US Department of Transportation’s (USDOT) Federal Transit Administration (FTA) announced approximately $182 million in funding for low- and no-emissions buses and the facilities that support them. New Mexico Department of Transportation. A total of 49 projects in 46 states and territories will receive funding through the program.

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. An important analytical issue that needs to be addressed, the report notes, is the lack of lifecycle assessment studies focusing on a wider set of environmental impact indicators than greenhouse gas emissions.
exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology.
A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment. of global ambient PM 2.5
A new international study has found that laboratory tests of nitrogen oxide emissions from diesel vehicles significantly underestimate the real-world emissions by as much as 50%. Those markets include Australia; Brazil; Canada; China; the European Union; India; Japan; Mexico; Russia; South Korea; and the United States.
Additionally, the study found that the population-weighted mean concentrations of ozone increased globally by 8.9% An additional 217,000 deaths were attributable to long-term ozone exposure. and ozone (O 3 ). . … and ozone (O 3 ). Somewhat similar patterns were also evident for ozone.
The founding coalition partners are Bangladesh, Canada, Ghana, Mexico, Sweden, and the United States, together with the UN Environment Programme (UNEP). This may be the only way to reduce climate impacts in the near term, and is a critical complement to the primary battle to reduce emissions of CO 2. Earlier post.). Earlier post.).
Low-input cultivation of perennial plants, e.g. from short-rotation forestry and grasslands, may be an effective source of cellulosic biomass and provide environmental benefits (reduced pollution and lower greenhouse gas emissions). However very few studies include water use impacts. This implies reaching agreement on of key parameters (e.g.
The California Air Resources Board (ARB) cited Dr. Wall for his leadership role in the development and implementation of all the major technology advancements ultimately leading to the near-zero levels of emissions of particulate matter and oxides of nitrogen from engines. Dr. Kirk R.
Hydrogen fueling at Toyota H2HQ Although big batteries and hydrogen fuel cells are often seen as two opposing ways to electrify trucks with no tailpipe emissions, Toyota is reworking the formula in its hydrogen fuel-cell semi to include both. With a supersized battery pack but no plug-in capability , Toyota makes more of the fuel-cell tech.
