UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

Global benefits from full implementation of the identified measures in 2030 compared to the reference scenario. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

Noting the references in scientific and policy literature to the need for fast-action mitigation to help avoid DAI and abrupt climate changes, the authors define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades.

Photochemical Ozone Creation Potential (kg Ethene equivalent). Quantifies the production of pollutant ozone (? to ozone layer), the results of the reaction of sunlight on NO x and volatile organic compounds. water, and non-renewable energies (crude oil, coal.)

PNNL team finds correlation between reaction mechanism for zeolite SCR catalyst for NOx aftertreatment and bacterial enzyme catalysis

Green Car Congress

Although the catalyst is in use, exactly how it converts NO x to nitrogen and water with the help of ammonia (urea) hasn’t been entirely clear. In some catalytic zeolites, the metal ions can break down the pollutant nitric oxide in vehicle emissions. Chemists refer to this orientation as “side-on”.

Here’s How We Could Brighten Clouds to Cool the Earth

Cars That Think

Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming. Such clouds might be less likely to produce rain, and the retained cloud water would keep albedo high.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

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. while noting that the analysis “.has
