UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The contribution of HFCs to climate forcing is currently less than 1% of all greenhouse gases. If HFC emissions continue to increase, they are likely to have a noticeable influence on the climate system. Climate and the Ozone Layer. Climate-friendly HFCs. W m -2 relative to 2000.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

While representatives of the palm oil industry have protested that the EPA findings are too harsh, correcting the analysis to reflect the more up-to-date information on the destruction of peatland suggests that palm oil biodiesel could be more climate-damaging than fuel from the Canadian oil sands.

Nornickel presents market review of nickel and platinum group metals

Green Car Congress

This is primarily due to a significant surplus in the Class 2 market that occurred in 2022 and is expected to remain throughout 2023-2024, mainly owing to growing production of low-grade nickel in Indonesia. At the same time, robust demand for nickel in alloys and special steel sectors supports prices of the exchange-traded Class 1 nickel.

Carnegie study finds climate impact of particulates varies greatly depending on where the pollution originated

Green Car Congress

However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. In many cases, the strongest climate effects of aerosols are felt far from where the aerosols are emitted.

Researchers show oil palm plantation expansion a significant source of CO2; projected to contribute more than all of Canada’s current fossil fuel emissions by 2020

Green Car Congress

The study, published as an open access paper in the journal Nature Climate Change , shows that deforestation for the development of oil palm plantations in Indonesian Borneo is becoming a globally significant source of carbon dioxide emissions. Indonesia is the leading producer of palm and palm kernel oil. Curran, Gregory P.
