for year 2007. A new black carbon (BC) emissions inventory from China found BC emissions levels in 2007 of 1,957 Gg BC—higher than reported in earlier studies. Black carbon is released into the atmosphere via incomplete combustion of carbonaceous fuel and is of major concern because of the impact on climate systems.
In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 In 2011, CH4 emissions from coal mining were 63.2

The US Department of Energy (DOE) in partnership with the US Air Force has issued a request for information (RFI)— DE-FOA-0000981 —on research & development aimed at greenhouse gas emissions reductions and cost competitiveness of Mil-Spec jet fuel production using coal-to-liquid (CTL) fuel technologies. Information Request.
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.
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 contrast to the “green light” for coal-to-NG substitution for power generation, the authors suggest that climate benefits from vehicle fuel substitution are uncertain (gasoline, light-duty) or improbable (diesel, heavy-duty). —Brandt et al.
The power sector has become less carbon-intensive as natural gas-fired generation displaced coal-fired and petroleum-fired generation and as the noncarbon sources of electricity generation—especially renewables such as wind and solar—have grown. That slightly outpaced the overall rate of inflation of 17% over that period.
Ceres recently released a new report concluding that coal-to-liquid (CTL) and oil shale technologies face significant environmental and financial obstacles—from water constraints, to technological uncertainties to regulatory and market risks—that pose substantial financial risks for investors involved in such projects.
Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%.

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.,
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).
A US Department of Energy/National Energy Technology Laboratory (NETL) team of regional partners has begun injecting CO 2 into a deep lignite coal seam in Burke County, North Dakota, to demonstrate the economic and environmental viability of geologic CO 2 storage in the US Great Plains region. In collaboration with Eagle Operating Inc.,
The proposed rulemaking establishes separate standards for natural gas and coal plants. coal units) are based on the performance of a new efficient coal unit implementing partial carbon capture and storage (CCS). Climate Change Coal Emissions Natural Gas Policy Power Generation' Background.

In 2009, the carbon intensity of the electric power sector decreased by nearly 4.3%, primarily due to fuel switching as the price of coal rose 6.8% Increased use of natural gas in place of coal caused the sector’s carbon intensity to decrease. In 2007, total consumption of petroleum-based fuels averaged 14,287 thousand barrels per day.
Since 2007, roughly 80% of spending on consumption subsidies occurred in countries that are net exporters of fossil fuels. million barrels per day, natural gas demand would be cut by 330 billion cubic meters, and coal demand would drop by 230 million tons of coal. Oil demand would be reduced by 3.7 in 2020 and 5.8%
million) toward a $30-million underground coal gasification (UCG) project with Swan Hills Synfuels of Calgary. Swan Hills Synfuels expects the project to demonstrate the ability to manufacture synthetic gas from Alberta’s coal resources, with the future potential of utilizing the coal seams for carbon capture and storage.
Assembly Bill (AB) 118 (Nùñez, Chapter 750, Statutes of 2007), created the Alternative and Renewable Fuel and Vehicle Technology Program (ARFVTP). The natural gas energy procured will replace electricity procured from a coal fired plant. The Intermountain Power Project Agency in western Utah operates the project.
Without decisive action, climate change 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 Climate Change. What have we learned since the fourth assessment?
The Age of Stupid is a 90-minute film about climate change, set in the future, which will have its world premiere in London on March 15th 2009 and then be released in UK cinemas on March 20th 2009, followed by other countries. Killer Coal Environmental Politics Saving Energy Pete Postlethwaite Sustainability solar power.
Overall, US energy-related CO 2 emissions have fallen 15% from their peak of 6,003 MMmt in 2007. CO 2 emissions from coal fell by 14.6%, the largest annual percentage drop in any fuel’s CO 2 emissions in EIA’s annual CO 2 data series dating back to 1973. The United States now emits less CO 2 from coal than from motor gasoline.
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.
With wind and even solar power increasingly competitive with coal and natural gas without subsidies, with many utilities needing to meet renewable portfolio standards, and with new EPA rules forcing coal plant retirements, the impact of lower oil prices on renewable energy in the US is expected to be insignificant.
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. Commercial aircraft emissions increased slightly between 2012 and 2013, but have decreased 18% since 2007.
Widespread climate-related impacts are occurring now in the US and are expected to increase. A product of the interagency US Global Change Research Program, the 190-page report was commissioned in 2007 and completed this spring. It is clear that climate change is happening now. Global Climate Change Impacts in the United States.
The emissions increase in the United States in 2013 (+2.5%) was mainly due to a shift in power production from gas back to coal together with an increase in gas consumption due to a higher demand for space heating. This is in contrast to most preceding years since 2007, in which annual oil consumption decreased by 2.2%

In particular in the US, where gasoline prices almost doubled in the summer of 2008 compared to 2007 levels, oil consumption dropped 7% decrease. In China, oil consumption increased by 3% in 2008, according to BP data, which was down from 5% in 2007 and 8%, on average, since 2001. Emissions increased by 1.7% in 2008, against 3.3%
Although emissions vary by plant and with the specific type of fuel, EPA provided illustrative examples of CO 2 emissions from EGUs: Conventional coal: 1,800 lbs CO 2 /MWh. Coal with carbon capture and storage (CCS): 200 lbs CO 2 /MWh. A company could build a coal?fired On 2 April 2007, in the Massachusetts v. Background.
The decrease in CO 2 emissions from fossil fuel combustion was a result of multiple factors, including a continued shift from coal to natural gas, increased use of renewables in the electric power sector, and milder weather that contributed to less overall electricity use. above 1990 levels in 2007. below 2005 levels.
Markey of the Energy and Environment Subcommittee on Tuesday released a draft of far-reaching energy and climate legislation that targets job creation, promotes renewables and energy efficiency, and places limits on emissions of greenhouse gases. Waxman of the Energy and Commerce Committee and Chairman Edward J. Clean Fuels and Vehicles.

Fossil fuel subsidies amount to hundreds of billions of dollars worldwide, and removing them has been held up as a key answer to climate change mitigation. That means that in some cases the removal of subsidies causes a switch to more emissions-intensive coal. This equates to 0.5-2 This equates to 0.5-2
billion tonnes in 2007). Between 1990 and 2010 they reduced their dependence on coal (from 25% to 20% of total energy production) and oil (from 38% to 36.5%), and shifted towards natural gas (which increased from 23% to 27 %), nuclear energy (from 8% to 9%) and renewable energy (from 6.5% billion tonnes in 2010 as compared to 4.2
—Dabo Guan, professor in climate change economics at UEA’s School of International Development and co-author on both studies. The success of international climate mitigation efforts may therefore depend on curtailing growth of coal-based energy and emissions in now-industrialising and urbanising countries.
Greenhouse Gas Emissions and Sinks , which is submitted annually to the Secretariat of the United Nations Framework Convention on Climate Change, presents a national-level overview of annual greenhouse gas emissions since 1990. Commercial aircraft emissions have decreased 19% since 2007. Climate Change Emissions' Tg CO 2 Eq.)

Among the findings of the EIA analysis: CO 2 emissions form natural gas surpassed those from coal in 2016. The natural gas share of electricity generation has grown as the coal share declined, partially offsetting the decline in energy-related CO 2 emissions from coal.
per year over 2007-2015 due to the displacement of coal by natural gas, wind and solar for power production as well as energy efficiency gains. Additional measures, including ways to offset the CO 2 emitted by liquid fuel use, will be needed to address the transportation-climate challenge. Source: John DeCicco. Click to enlarge.
We have had a long debate about climate change in this country. Most Australians now agree our climate is changing, this is caused by carbon pollution, this has harmful effects on our environment and on the economy—and the Government should act. A lot has happened since then; the debate has been difficult and divisive.
