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. The CO 2 emissions from burning this coal will also decline by 50%.
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. The researchers argue for a global economy-wide greenhouse gas tax that spreads the burden of responsibility.
This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. An increase in natural gas generation offset some of the climate gains from this coal decline, but overall power sector emissions still decreased by almost 10%.
The top graph depicts CTL in a no policy scenario; the bottom graph, for CTL in a world climate policy scenario. However, the viability of CTL becomes quite limited in regions with climate policy due to the high conversion cost and huge carbon footprint. Credit: Chen et al., 2011 Click to enlarge.
Among the transportation-related elements of US President Barack Obama’s new climate action plan, which he is outlining today in a speech at Georgetown University, is the development of new fuel economy standards for heavy-duty vehicles post-2018. Preparing the US for the impacts of climate change. Earlier post.).
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.

Global energy-related carbon dioxide emissions were flat for a third straight year in 2016 even as the global economy grew, according to the International Energy Agency. gigatonnes last year, the same as the previous two years, while the global economy grew 3.1%, according to estimates from the IEA.
These figures raise the pressing question of whether scarce government funds might be better allocated to move the United States towards a low-carbon economy. billion—are attributable to corn-based ethanol, the climate effects of which are disputed. billion went to traditional sources—such as coal and oil—and $2.3 Adeyeye et al.
Major economies led the resurgence as a pick-up in economic activity pushed energy demand higher and significant policies measures to boost clean energy were lacking. Many economies are now seeing emissions climbing above pre-crisis levels. China was the only major economy that grew in 2020.
This decrease was driven largely by a decrease in emissions from fossil fuel combustion resulting from a decrease in total energy use in 2019 compared to 2018 and a continued shift from coal to natural gas and renewables in the electric power sector. CO 2 emissions decreased 2.2% from 2018 to 2019.
In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)
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
These questions include how shale gas will affect the national and global economy, local environments and communities, global energy markets, geopolitics, and more. In this paper, we focus on the implications of growing shale gas production for the climate. . … With this abundance of natural gas comes a variety of questions.
World energy growth over the next twenty years is expected to be dominated by emerging economies such as China, India, Russia and Brazil while improvements in energy efficiency measures are set to accelerate, according to BP’s latest projection of energy trends, the BP Energy Outlook 2030. Coal will increase by 1.2% Click to enlarge.
Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).
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.,
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.
The large decline in emissions, achieved before the COVID-19 crisis, was mainly due to reduced coal use for power generation. The official data, submitted on behalf of the EU to the United Nations Framework Convention on Climate Change (UNFCCC), show that EU Member States managed to reduce collectively their emissions by 3.8%
The Administration said that the ambitious target is grounded in analysis of cost-effective carbon pollution reductions achievable under existing law and will keep the United States on a trajectory to achieve deep economy-wide reductions on the order of 80% by 2050.
The 2009 results reflect a combination of factors, EIA said, including some particular to the economic downturn; other special circumstances during the year; and other factors that may reflect persistent trends in the economy and in energy use. Increased use of natural gas in place of coal caused the sector’s carbon intensity to decrease.
The IEA said that this reflects the continued domination of fossil fuels—particularly coal—in the energy mix and the slow uptake of other, lower-carbon supply technologies. Emerging economies are stepping up their efforts to promote and develop clean energy. In 1990 the underlying carbon intensity of supply was 57.1
However, reform has been hampered by concerns over how higher fuel prices will affect the broader economy—potentially disrupting key sectors like transport, industry and agriculture—and the ability of poor citizens to cope with higher prices. Oil demand would be reduced by 3.7 in 2020 and 5.8%
Tax rates were below the low-end estimate of climate costs (EUR 30/tCO 2 ) for 97% of emissions. The report found that the share of emissions taxed above climate costs increased from 46% in 2012 to 50% in 2015, and rates exceed €50 per tCO 2 for 47% of emissions in 2015, compared to 37% in 2012. —“Taxing Energy Use 2018”.

The low annual rate of global reduction of carbon emissions per unit of GDP needed to limit global warming to 2 °C—based on the probability assessments of the UN IPCC—is insufficient to achieve that goal, according to the latest Low Carbon Economy Index published by business consultancy PwC. —PwC.
The new report, part of the World Energy Outlook (WEO) 2011 series, examines the key factors that could result in a more prominent role for natural gas in the global energy mix, and the implications for other fuels, energy security and climate change. It is clean and flexible.
The Darlington SMR will provide a critical new source of clean nuclear energy for Ontario’s future projected energy capacity needs—a demand widely expected to ramp up as transportation and other sectors electrify, using Ontario’s clean power to help decarbonize the broader economy. Spur SMR deployment elsewhere in Canada and abroad.
The decrease was driven by the economic downturn, combined with a significant switch from coal to natural gas as a source of electricity generation, according to the EIA. An improving economy is expected to increase CO 2 emissions from fossil fuels by 0.7% decline in coal-based CO 2 emissions for 2009. Petroleum. Natural Gas.
trillion in 2010) would be required to overcome poverty; increase food production to eradicate hunger without degrading land and water resources; and avert the climate change catastrophe. These trends, which are diametrically opposed to declared greenhouse gas mitigation goals and targets, are by no means limited to emerging economies.
The Industrial Revolution that started around 1750 in England was powered largely by coal. With Watt's invention of the steam engine and the emergence of railways in the mid-nineteenth century, the carbon-dense fuel was central to the change from an agricultural economy to an industrial one.
Simple, effective solutions that can help lessen the impact of climate change already exist. Rahman, a power expert and professor of electrical and computer engineering at Virginia Tech , is the former chair of the IEEE ad hoc committee on climate change. One type is the ultrasupercritical coal-fired steam power plant.
There is evidence that fossil fuel subsidies are socially inequitable, that they encourage smuggling and waste, and distort economies in ways that undermine economic efficiency while harming the environment and the climate,” wrote Jim Krane, the Wallace S.
Because of continuing trends in how much energy the US economy uses and how much CO 2 that energy use generates, energy-related CO 2 emissions in 2019 fell more than energy consumption, which declined by 0.9% The United States now emits less CO 2 from coal than from motor gasoline. US energy-related CO 2 emissions declined by 2.8%
Trestle and Larksen’s integrated approach furthers ethanol producers’ ability to scale up production of low carbon biofuels and allows existing power plants to generate electricity with the cost and reliability of coal and with carbon emissions similar to wind.
I know I should be in Washington DC in two weeks to help take over the capitol on behalf of green jobs, clean energy and ending our carbon-based economy. I can’t understand why there aren’t rings of young people blocking bulldozers and preventing them from constructing coal-fired power plants.” - Al Gore.
Ukraine’s next crisis will be a devastatingly economic one, as violent conflict destroys critical infrastructure in the east and brings key industry to a halt, furthering weakening the energy sector by crippling coal-based electricity production. Key industry sources say they will potentially run out of coal in less than three weeks.
