In other Neste news, the effectiveness of Neste MY Renewable Jet Fuel in reducing black carbon emissions has been recognized in a competition organized by the Climate Leadership Coalition, the Bioenergy Association of Finland, the Finnish Innovation Fund Sitra, the Finnish Environment Institute, and the Central Association of Chimney Sweeps. According to NASA, renewable fuel has the potential to cut particulate emissions by up to 70 pct from aircraft engines.

In particular, the researchers determined that the emissions from several key sources -- pre-1980 residential boilers and heating stoves, specific off-road engines, and heavy-duty diesel and light-duty gasoline-powered vehicles assembled prior to 1970 -- should be increased significantly.
According to the research, between 1960 and 1980, the updated U.S. emissions totaled approximately 690 gigagrams per year in 1960 and 620 gigagrams per year a decade later. The revised inventory also exhibits a decreasing trend through 1980 that is not apparent in earlier reports.

Now, a new 5-year search study has found that fossil fuel combustion is the main contributor to black carbon 9ssot). The research, which collected raw data in Alaska, Russia, Canada, Sweden, and Norway, found that fossil fuel combustion was responsible for most of the black carbon in the Arctic, annually around 60 pct. The findings are an important call to decrease worldwide fossil fuel consumption.
The study is published in the journal Science Advances, a publication of the American Association for the Advancement of Science.

The U.N. award recognizes California Senate Bill 1383
aimed at cutting California's methane and hydrofluorocarbon gases to 40 pct and black carbon to 50 pct below 2013 levels by 2030. This year, the California Air Resources Board (CARB) began the process of meeting the bill's targetswith the approval of approved new regulations to cut down on methane emissions from oil and gas field operations by more closely monitoring and repairing methane leaks.

As the Washington Post reports, researchers have for the first time tracked soot's journey between these points and noted the presence of soot is helping to speed up the Greenland Ice Sheet's melt, which could eventually contribute to global rising sea levels by more than 6m (20ft). The Post also reports that sea level rise is happening faster than anticipated and that atmospheric CO2 levels are increasing even as global emission levels have stabilized.

Black carbon darkens ice in the Arctic and reduces the albedo of snow, thereby speeding up melting. The main sources of black carbon emissions in the Arctic are vehicles and companies that use wood and coal, as well as forest fires, power stations and gas flares at oil fields.
The Arctic Council is an intergovernmental forum of the Arctic states (Russia, Canada, the United States and North European countries) and Arctic indigenous communities. It focuses on environmental monitoring, identification of pollution risks, preparedness for environmental accidents, sustainable development, conservation of natural diversity, and questions related to the Arctic sea areas.

The new strategy sets targets for reducing super pollutants emissions by 2030. Methane and hydrofluorocarbons would need to be cut to 40 pct below 2013 levels, and black carbon would need to be reduced to 50 pct below 2013 levels. Meeting the goals could require more efficient refrigerators, replacing wood stoves and diverting waste from landfills. Some of the projects would involve incentives funded with public dollars. The biggest and most controversial changes could occur at dairies, where manure contributes an estimated 25 pct of the state's methane emissions. (Source: CARB, LA Times, 23 Mar., 2017)

The plan targets emissions such as methane from cow manure, black carbon from diesel exhaust and hydrofluorocarbons from refrigerators. Regulators at the Air Resources Board, which approved the strategy, and other government agencies will now need to write detailed rules for achieving the reductions.
As the world races to limit rising temperatures from climate change, some experts have suggested that targeting these pollutants could help make big gains more quickly. They hope the state's action will help demonstrate policies that other governments could imitate.
The emissions are sometimes referred to as “short-lived climate pollutants” because they have a relatively short life span once they’re dispersed into the atmosphere. But they’re particularly potent — methane, for example, is about 80 times more damaging in terms of heating the atmosphere than carbon dioxide.
The law sets targets for reducing certain emissions by 2030. Methane and hydrofluorocarbons would need to be cut to 40% below 2013 levels, and black carbon would need to be reduced to 50% below 2013 levels.

HFO, a toxic, tar-like sludge that breaks down extremely slowly in cold Arctic waters, is virtually impossible to clean up in the event of a spill and thus poses a severe risk to the Arctic marine environment, related industries and coastal communities.
The burning of heavy fuel oil by ships emits significant quantities of black carbon, potent in accelerating the already rapid pace of Arctic climate change. In the Arctic atmosphere, black carbon absorbs heat from the sun and reflected heat from the snow and ice doubling the warming impact when it settles on the snow and ice surfaces. This increases the surface area of exposed, dark ocean water, and promotes a self-reinforcing cycle of land and sea ice melting and climate warming.
