The Seattle City Council unanimously passed Resolution 31379 stating Seattle’s opposition to the transportation of coal through Seattle. There are currently four coal exports under permit review in the Northwest that collectively could increase US coal exports by 150 million tons of coal annually.
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. Improving coordination and support for research efforts on climatechange preparedness.
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.
Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climatechange problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Tags: ClimateChange Emissions. Earlier post.)
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. Transportation. CO 2 emissions decreased 2.2% from 2018 to 2019. over the same period.

MIT researchers have built a model to simulate long-range atmospheric transport of polycyclic aromatic hydrocarbons (PAHs). For emerging contaminants in the Arctic, we need to know more about their sources, environmental behavior, and transport pathways in order to regulate them more effectively. —Noelle Selin, lead researcher.
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. Transportation. Tags: ClimateChange Emissions. Click to enlarge.
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 Transportation sector carbon dioxide emissions in 2008 were 95.6
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. Coal technologies continue to dominate growth in power generation. Around half of coal-fired power plants built in 2011 use inefficient technologies.
Oregon Governor Ted Kulongoski signed into law a series of bills constituting a climatechange package that includes a low carbon fuel standard (LCFS), a B2 mandate, and other transportation-related measures. The series of bills the Governor signed into law today include: House Bill 2186. Senate Bill 38. House Bill 3463.
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)
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. Coal accounted for over 40% of the overall growth in global CO 2 emissions in 2021, reaching an all-time high of 15.3 billion tonnes.
Analysis by the International Council on Clean Transportation (ICCT) argues that EVs are the quickest means to decarbonize motorized transport. Transportation accounts for only 27 percent of greenhouse gas emissions (GHG) in the U.S.; If Birol were from Maine, he might have simply observed , “You can’t get there from here.”
Widespread climate-related impacts are occurring now in the US and are expected to increase.

ClimateChange Emissions' In terms of per capita emissions, the top emitter was Wyoming (118.5
We found that converting biomass to electricity rather than ethanol makes the most sense for two policy-relevant issues, transportation and climate.” The net transportation output per hectare is larger for the bioelectricity case. Kilometers per crop hectare for switchgrass feedstock with a small SUV. Campbell et al.
The Excel-based Upstream Dashboard provides “upstream” data for lifecycle analysis of coal, natural gas, crude oil, uranium, and biomass, as well as gasoline, ethanol, jet fuel, and diesel derived from either petroleum or coal-gasification. Results are listed in a chart as well as illustrated in a bar graph.
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. The STEO projects that petroleum CO 2 emissions will decline by 4% in 2009, primarily due to declines in transportation sector consumption.
This calculation includes all CO 2 emissions grouped under Scope 1 and 2 categories as set out by the Greenhouse Gas Protocol as well those associated with transporting material between production and refining sites. For the purposes of this analysis, emissions are classed as any anthropogenic sources of CO 2.
Under the scheme, around 500 of the largest emitters in Australia—facilities that have direct greenhouse gas emissions of 25,000 tonnes of CO 2 -equivalent per year or more (excluding emissions from transport fuels and some synthetic greenhouse gases)—will need to buy and surrender to the Government a permit for every tonne they produce.
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.).
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.
Greenhouse gas (GHG) emissions across the European Union rose slightly in 2017, mostly because of the transport sector. The rise is mostly due to the increase of oil consumption from road transport. The energy sector was able to reduce its emissions due to the decreasing share of coal used to produce electricity and heat in the EU.

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. and 15¢ per kWh, while subsidies for fossil fuels were estimated at around 0.1–0.7¢
Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. Increased use of coal relative to other energy sources has reversed the long?standing Transport sector.
Trevor St Baker is one of the smart billionaires in Australia who is investing serious money in the transportation sector to promote the changeover to EVs despite his history and vocal support for coal-fired power stations. He is a coal baron who drives a Tesla Model 3, and he is building an EV ecosystem. After […].
Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. Rather, it is the leaking of hydrogen from production, transportation and usage that adds to global warming. The open-access paper is published in Nature Communications Earth & Environment.
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. Essentially, this would require making the power and transport sector carbon-free worldwide.
