the distribution of black carbon in the atmosphere and determine its role in the climate system. Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’s climate impact.
This article shows that including offsets in climatechange legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. 3) Measurement. CONCLUSION.

A new study by researchers from the US Environmental Protection Agency (EPA) finds substantial gaps in the amount of research on the numerous critical topics relevant to the global biofuels industry.
In response to the ongoing discussion about the reliability of the UN IPCC and the climate reports, a group of 55 leading Dutch scientists working in the field of climatechange, energy and the environment wrote an open letter. Errors in the IPCC climatechange report are being seized by some to discredit climate science.
Developing technology to address the causes of climatechange, mitigate its impact, and adapt to the crisis is one of IEEE’s top priorities. To assist with that effort, the IEEE Young Professionals group this year launched its Climate and Sustainability Task Force.
Despite the much-vaunted megatrend involving the global electrification drive and shift to renewable energy , the most ambitious pledges by Big Oil to pursue net-zero agendas remain weak at best. As we have pointed above, ENI has the most ambitious climatechange pledge with plans to lower its greenhouse gas emissions by 80% by 2050.

This article is part of our special report Top Tech 2024. The] Climate Foundation is trying to harvest, which is great,” he says.
Globally 131 million tons of ammonia were produced in 2010. Globally 245 million tons of CO 2 were released by the ammonia industry in 2010 equivalent to about 50% of the UK CO 2 emissions (495.8 Scientific Reports 3, Article number: 1145 doi: 10.1038/srep01145. tons of CO 2 is released per ton of ammonia produced.
In the new article, they point out that in addition to saving human lives and boosting global food security, curbing SLCPs will significantly slow the pace of climatechange over the next 25 years.
In their paper on the new microwave-driven Pidgeon process, the researchers observed that: The lightweight nature of Mg, combined with its high energy density, suggests that the global consumption of this metal will increase drastically in the near future. … Yuji Wada, Satoshi Fujii, Eiichi Suzuki, Masato M.
