BNEF, Snam, IGU report finds global gas industry set to resume growth post-pandemic; low-carbon technologies for long-term growth

Green Car Congress

However, the resulting low gas prices, as well as clean air and climate policies, will promote further switching to gas from other more polluting energy sources, such as oil and coal. The development of an international hydrogen market could also accelerate adoption. —Ashish Sethia, global head of commodities at BNEF.

UK government launches new clean air strategy; ending sales of conventional diesel and gasoline LDVs by 2040

Green Car Congress

UK Environment Secretary Michael Gove published a new Clean Air Strategy to cut air pollution backed up through new primary legislation. The UK said it will go further and faster than the EU in reducing human exposure to particulate matter pollution. These proposals are in addition to the government’s £3.5-billion billion (US$4.7-billion)

Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

An international team of researchers has shed light on one way new particles are forming in the upper troposphere. There are no factories or farms, and planes are thought to make up most of the pollutants in this area. This is important, especially in the relatively clean upper troposphere. The emission sources are limited up there.

Global CO2 emissions stalled for the third year in a row

Green Car Congress

Emissions from international transport (aviation and shipping) contribute another 3% to the total global GHG emissions. CH 4 is mainly generated by agricultural activities, the production of coal and gas, as well as waste treatment and disposal. Other greenhouse gases keep creeping up.

Why Do Japanese Automakers Like Hydrogen Power?

The Truth About Cars

But the focus is not on hydrogen fuel cell vehicles that utilize electricity for propulsion, they’ll be developing internal combustion engines that burn hydrogen in lieu of gasoline — with the assumption benign that they’ll produce fewer carbon dioxide emissions. That seems to be the new trend. But such a breakthrough seems a long way off.

CMU/DAI study finds shutting down US nuclear plants would have significant negative economic and environmental consequences

Green Car Congress

Shifting from nuclear to other types of power plants could affect the reliability of the electricity supply, electricity costs, air pollution, carbon emissions, and the reliance on fossil fuels such as coal and natural gas, the researchers said. The calculated cost of generation with the new mix of plants was a lower bound.

Fast action on black carbon, ozone and methane could help limit global temperature rise to 2 degrees C

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)—and ventilation air from coal mines. Replacing coal by coal briquettes in cooking and heating stoves.
