Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

The report’s best estimate of direct climate influence by black carbon is about a factor of two higher than most previous work. This includes the estimates in the 2007 Intergovernmental Panel on Climate Change (IPCC) Assessment, which were based on the best available evidence and analysis at that time.

ITF: measures to decrease road freight CO2 emissions

Green Car Congress

It collects insights held at a workshop organized by the International Transport Forum in June 2018 in Paris and features the results of a survey among experts. However, achieving climate change targets will also require the widespread adoption of solutions that are not yet fully developed, whether in logistics or technology.

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).

Study Finds Availability of Low-CO2 Electricity and Hydrogen May Paradoxically Delay Large-Scale Transition to Electric and/or Hydrogen Vehicle Fleet

Green Car Congress

The cost-effectiveness of measures to address climate change is enhanced through a multisector perspective. While the model we have used is simple in some respects and has limitations, it nevertheless provides the first insight into the existence and magnitude of this effect. Wallington et al.

DOE Regional Partnership Initiates CO2 Injection in Lignite Coal Seam

Green Car Congress

In addition to evaluating the lignite seam’s CO2 storage potential, the enhancement to coalbed methane extraction will also be evaluated. The field-based investigations conducted under this activity will provide previously unavailable insight regarding the sequestration of CO 2 in low-rank coals.

Study: countries seeking to cut CO2 emissions must get a handle on city-level emissions

Green Car Congress

The researchers set out a framework for gathering and analyzing local information about how cities contribute to pollution levels, and show how these insights could be used to target climate mitigation initiatives most effectively. Everything practical that you would need to do to reduce emissions happens at a city level.

First snapshots of CO2 molecules trapped in MOFs shed new light on carbon capture

Green Car Congress

This is a groundbreaking achievement that is sure to bring unprecedented insights into how these highly porous structures carry out their exceptional functions, and it demonstrates the power of cryo-EM for solving a particularly difficult problem in MOF chemistry. degrees Celsius will require some form of carbon capture technology.
