Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. —Tom Wigley.
A multi-Hubbert analysis of coal production by Tadeusz Patzek at The University of Texas at Austin and Gregory Croft at the University of California, Berkeley concludes that the global peak of coal production from existing coalfields will occur close to the year 2011. Gt C (15 Gt CO 2 ) per year, according to the study.
The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.
The report—titled “The Role of China in Mitigating Climate Change” and published in the journal Energy Economics , compares the impact of a stringent emissions reduction policy with and without China’s participation. Eighty percent of those emissions came from coal, making China the consumer of about half the world’s coal.
A) CNG light-duty cars vs. gasoline cars; (B) CNG heavy-duty vehicles vs. diesel vehicles; and (C) combined-cycle natural gas plants vs. supercritical coal plants using low-CH 4 coal. Recent reports in the scientific literature and popular press have produced confusion about the climate implications of natural gas.
“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds. —Howarth and Jacobson.

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.
The researchers found that while EVs do offer a very promising solution to energy issues due to their replacement of petroleum fuels, for now “ the high pollution levels of coal-fired power plants will trade off EVs’ potential energy benefits in China ”. The power of EVs is electricity from the grid.

Source: van Vliet et al.
While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University. —Newell and Raimi.
Coal combustion alone was responsible for half of those deaths, with natural gas and oil combustion accounting for the other half. in outdoor air comes from anthropogenic fuel combustion, suggesting that integrating air quality, energy, and climate policies is likely to bring substantial health benefits.
To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, according to a new report from the National Academies of Sciences, Engineering, and Medicine.
As part of its tkH2Steel transformation project, coal-based blast furnaces will be replaced by hydrogen-powered direct reduction plants. Thus, the Duisburg steelworks is continuing to boil steel as in the past—but with hydrogen and green power instead of coal. —Martina Merz, CEO of thyssenkrupp AG. With its capacity of 2.5
A NASA-led team of scientists has uncovered strong evidence that coal soot from a rapidly industrializing Europe caused the abrupt retreat of mountain glaciers in the European Alps that began in the 1860s, a period often thought of as the end of the Little Ice Age (LIA). —Georg Kaser, a study co-author from the University of Innsbruck.
Researchers from the University of Birmingham have designed a novel adaptation for existing blast furnaces that could reduce CO 2 emissions from the steelmaking industry by nearly 90%. If implemented in the UK alone, the system could deliver cost savings of £1.28 billion in 5 years while reducing overall UK emissions by 2.9%.
Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. Upstream emissions are emissions, including from leaks and combustion, from mining and transporting a fuel such as coal or natural gas.). A study by Mark Z.
Without systematic, transformative changes, the US is unlikely to succeed either in averting the worst economic and environmental consequences of climate change or in achieving a secure, affordable and reliable energy supply. The project was supported by a grant from the Doris Duke Charitable Foundation. —Richard Lester.
Although most countries have already revealed their opening emissions reduction proposals, UNFCCC Executive Secretary Yvo de Boer pointed out Thursday that “ we still await clarity from industrialized nations on the provision of large-scale finance to developing countries for immediate and long-term climate action. by Jack Rosebro.
Cutting the amount of short-lived, climate-warming emissions such as soot and methane won’t limit global warming as much as previous studies have suggested, according to a new study from the Joint Global Change Research Institute in College Park, Md., More realistic emission reductions would likely provide an even smaller climate benefit.
This article shows that including offsets in climate change 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. Assuming the offset is legitimate—i.e.,
Black carbon (BC) from incomplete biomass and fossil fuel combustion is the most strongly light-absorbing component of particulate matter (PM) air pollution and a major climate-forcing emission. Air pollution mitigation efforts focusing on reducing combustion pollution are likely to have major benefits for climate and human health.
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 climate change, energy and the environment wrote an open letter. Errors in the IPCC climate change report are being seized by some to discredit climate science.

In Alberta, for example, CO 2 emissions from coal-fired electric power exceed emissions from oil sands and the costs of reducing emissions from coal electricity are lower. Yet, coal-fired emissions in Alberta receive relatively little attention from environmental organizations and the public. Why then the focus on oil sands?
