Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

The most immediate, effective and low-cost way to reduce soot emissions is to put particle traps on vehicles, diesel trucks, buses, and construction equipment. 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b]. Particle traps filter out soot particles from exhaust fumes.

New international Climate and Clean Air Coalition to focus on reduction of short-lived climate pollutants

Green Car Congress

Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near-term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F), Moreover, many of these benefits can be achieved at low cost and with significant energy savings. Earlier post.).

NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

And hydroxyls drive long chains of reactions involving other common gases, including ozone. That’s noteworthy because nitrogen oxides have primarily been associated with ozone formation and warming in the past. In the chemical soup of the lower atmosphere, however, sulfur dioxide isn’t the only substance interacting with hydroxyl.

North American Countries Target “Super” Greenhouse Gases Through Strengthened Ozone Treaty

Green Car Congress

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. Source: IGSD.

OptiFuel finalizing $2.6M DOE grant to demonstrate RNG hybrid line-haul locomotive

Green Car Congress

OptiFuel has already developed and tested a high volume CNG/RNG refueling system at the Indiana Harbor Belt CNG locomotive program, utilizing low-cost CNG. These pollutants create very high levels of ozone, air toxins, greenhouse gases, fine particulate matter, and other diesel exhaust compounds classified as carcinogenic to humans.
