New Mexico Adopts Greenhouse Gas Cap-and-Trade Program

Green Car Congress

The New Mexico Environmental Improvement Board (EIB) adopted by a vote of four to three greenhouse gas reduction regulations—called the most stringent in the US—that will reduce global warming pollutants through a regional cap on greenhouse gas emissions. New Mexico Greenhouse Gas Cap-and-Trade Regulation.

USDOT FTA announces $182M in Low-No grants for transit vehicles & facilities nationwide

Green Car Congress

The electric buses will replace CTA’s oldest diesel buses and reduce greenhouse gases in communities that have experienced air pollution and other environmental health hazards, improving public health and quality of life. By retrofitting the garage to service electric buses, the agency will also lower pollution in the surrounding community.

NSF launches $20M engineering research center aimed at converting natural gas into transportation fuels: CISTAR

Green Car Congress

The CISTAR approach could decrease the amount of greenhouse gases and air pollutants, while reducing chilled and pressurized trucking of light hydrocarbons and simplifying transportation of fuels to end users. Inform the public about safe and environmentally responsible ways to use U.S. hydrocarbon resources.

California ARB greenlights states GHG cap-and-trade program

Green Car Congress

The program is designed to provide covered entities the flexibility to seek out and implement the lowest-cost options to reduce emissions. A Memorandum of Understanding has already been signed with Chiapas, Mexico, and Acre, Brazil, at the Governor’s Global Climate Summit 3 to establish these offset programs. Click to enlarge.

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

The Advanced Collaborative Emissions Study (ACES), released today by the Health Effects Institute (HEI), also confirmed that the concentrations of particulate matter and toxic air pollutants emitted from NTDE are more than 90% lower than emissions from traditional older diesel engines (TDE).

US study of miners links heavy exposure to diesel exhaust to increased risk of lung cancer death; researchers suggest implications for urban areas with high exhaust concentrations

Green Car Congress

Some of the higher average elemental carbon levels reported in cities include Los Angeles (4.0 µg/m 3 ), Mexico City (5.8 Because such workers had at least a 50% increased lung cancer risk, our results suggest that the high air concentrations of elemental carbon reported in some urban areas may confer increased risk of lung cancer.

Researchers develop effective exhaust catalyst for lower temperature exhaust

Green Car Congress

To improve fuel efficiency, advanced combustion engines are being designed to minimize the amount of waste heat in the exhaust. Their work, published this week in the journal Science , presents a new way to create a more powerful catalyst while using smaller amounts of platinum—the most expensive component of emission-control catalysts.
