A new report from the MIT Joint Program on the Science and Policy of Global Change shows the importance of all major nations taking part in global efforts to reduce emissions—and in particular, finds China’s role to be crucial. The researchers argue for a global economy-wide greenhouse gas tax that spreads the burden of responsibility.
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%.
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 President’s Council of Advisors on Science and Technology (PCAST) released a letter to President Obama describing six key components the advisory group believes should be central to the Administration’s strategy for addressing climatechange. —PCAST letter to the President. The six key components are: 1.
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.
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. Assuming the offset is legitimate—i.e.,
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 climatechange, according to a new report from the National Academies of Sciences, Engineering, and Medicine.
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.
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.
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 climatechange. Earlier post.).
billion tonnes, their highest ever level, as the world economy rebounded strongly from the COVID-19 crisis and relied heavily on coal to power that growth, according to new IEA analysis. China was the only major economy to experience economic growth in both 2020 and 2021. billion tonnes. billion tonnes.
While the number of new clean power-generating plants completed stayed flat year-to-year, the volume of power derived from coal surged to a new high, according to Climatescope , an annual survey of 104 emerging markets conducted by research firm BloombergNEF (BNEF). thousand terawatt-hours in 2018, up from 6.4 thousand in 2017.
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.

Simple, effective solutions that can help lessen the impact of climatechange 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 climatechange. One type is the ultrasupercritical coal-fired steam power plant.
The technology group Wärtsilä has issued a report ahead of COP26, the UN’s ClimateChange Conference to be held in Glasgow this autumn, describing the environmental and economic opportunities for states that decarbonize rapidly. coal and gas), significantly reducing the overall levelised cost of electricity.
Without decisive action, climatechange this century is likely to accelerate at a much faster pace and cause more environmental damage than predicted, according to Professor Chris Field of Stanford University, and a leading member of the UN Intergovernmental Panel on ClimateChange.
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 ClimateChange (UNFCCC), show that EU Member States managed to reduce collectively their emissions by 3.8%
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)
Canada’s First Ministers (The Prime Minister of Canada and the provincial and territorial premiers) issued a joint communiqué and released the Pan-Canadian Framework on Clean Growth and ClimateChange following the First Ministers’ Meeting. The Framework outlines actions that will grow the economy while reducing GHG emissions.
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.
The report, Taxing Energy Use 2018 is based on OECD’s Taxing Energy Use database, a unique dataset to compare coverage and magnitude of specific taxes on energy use across 42 OECD and G20 economies (representing approximately 80% of global energy use), six sectors and five main fuel types. —“Taxing Energy Use 2018”. of emissions.
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 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.
In states (or countries ) with a high proportion of coal-generated electricity, the miles needed to break-even climb more. Behavioral change is hard How willing are people to break their car dependency and other energy-related behaviors to address climatechange? The answer is perhaps some, but maybe not too much.
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 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.
IEEE continues to raise its visibility as a trusted voice on mitigating the effects of climatechange. ClimateChange Conference (COP29). Then in December, IEEE and the International Telecommunication Union held a symposium on achieving climate resilience.
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%
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.
The use of coal as a fuel has now surpassed oil and developing countries now emit more greenhouse gases than developed countries, with a quarter of their growth in emissions accounted for by increased trade with the West. Emissions from coal are now the dominant fossil fuel emission source, surpassing 40 years of oil emission prevalence.
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.
“Pack Up Your Toxic, Fossil Fuel Factory With Its Climate-Changing Products & Get Out of Town By 2020!&# I’m thinking he likes our carbon-based economy just the way it is. is also the very same company that has paid tens of millions of dollars, year after year to spread FUD about their role in climatechange.
To determine GHG emissions, UCS considered the fuel economy, fuel type, and sales volume of each type of vehicle sold by each automaker in the 2013 model year (MY2013). ClimateChangeCoal Emissions Fuel Efficiency' Methodology.
trillion in 2010) would be required to overcome poverty; increase food production to eradicate hunger without degrading land and water resources; and avert the climatechange 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.
Greenhouse gas emissions in the US economy, 2008. There were small percentage increases in emissions of other greenhouse gases, but their absolute contributions to the change in total emissions were relatively small, with the increase in emissions of those gases being more than offset by the drop in CO 2 emissions: 14.8 Source: EIA.
The increase from 2012 to 2013 was due to an increase in the carbon intensity of fuels consumed to generate electricity due to an increase in coal consumption, with decreased natural gas consumption, according to the report. ClimateChange Emissions' Total US emissions have increased by 5.9% from 1990 to 2013.
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 changes in US energy-related CO 2 emissions in 2019 offset the increase in 2018. CO 2 emissions had increased by 2.9%
The WCI is a collaborative of seven western states and four Canadian provinces that are developing strategies to address climatechange. Economic analyses show a modest net benefit to the New Mexico economy as a result of reducing greenhouse gas emissions and promoting clean energy jobs.
For example, rich countries such as Germany can throw billions of dollars at their coal sector to ease their transition pain, offering generous financial aid to lignite-producing regions. This scenario assumes a full global consensus for action on climatechange. The result is a win–win for climate and security.
