Columbia University engineers make breakthrough in understanding electroreduction of CO2 for conversion to electrofuels

Green Car Congress

They applied a comprehensive suite of experimental and theoretical methods to identify the structure of the first intermediate of CO 2 electroreduction: carboxylate CO2 - that is attached to the surface with C and O atoms. Their paper is published in Proceedings of the National Academy of Sciences (PNAS).

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

Green Car Congress

Shown are the tipping elements [large-scale components of the Earth’s system] and the temperature threshold range that initiates the tipping. The Montreal Protocol has already delayed climate change by seven to 12 years, and put the ozone layer on the path to recovery later this century. Climate policy. From Molina et al.

Study: expanding Brazilian sugarcane for ethanol could reduce global CO2 emissions by up to 5.6%

Green Car Congress

However, it could be accomplished without impinging on environmentally sensitive areas in Brazil and while allowing for the expansion of other agricultural crops and human needs, the researchers report in a paper in the journal Nature Climate Change. The corresponding range of CO 2 offsets is 0.55–2.0 Gigatons yr −1.

This Startup Is Building the Internet of Underwater Things

Cars That Think

Water covers 72 percent of the Earth’s surface, its volumes host 80 percent of biodiversity and play a pivotal role in global phenomena, such as climate change. Data transfer between the nodes is permanently optimized by AI: Whenever sea conditions change, algorithms modify the path followed by byte packets.
