The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.
million metric tons of carbon dioxide equivalents, or 5,586.0 million metric tons of carbon dioxide equivalents after accounting for sequestration from the land sector—representing a 6% increase from 2020. This report has been compiled annually since 1993 and submitted to the United Nations Framework Convention on ClimateChange.
Since then, LTD hired a Sustainability Program Manager and conducted carbon footprint analysis of its operations to measure the impacts and benefits of public transit on climatechange. Since 2004, NFI has delivered 50 buses to LTD, including New Flyer transit buses and low-floor cutaway buses from NFI sister company ARBOC.
Since carbon dioxide emissions are highly correlated with fuel consumption (FC), fuel consumption regulation is a useful policy instrument to combat climatechange.
Researchers at Peking University have developed a new methodology to model black carbon (BC) emissions from diesel and gasoline motor vehicles. Black carbon is a key short-lived climatechange forcer ( earlier post ) and motor vehicles are important sources of BC in the environment. Credit: ACS, Wang et al. Streets, D.
As areas with permafrost thaw and more old carbon is released, the carbon balance changes. Permafrost thaw will make potentially significant contributions to atmospheric concentrations of carbon more rapidly that previously thought, according to a new study published in the 28 May issue of the journal Nature. Vogel et al.
Greenhouse Gas Emissions and Sinks , which is submitted annually to the Secretariat of the United Nations Framework Convention on ClimateChange, presents a national-level overview of annual greenhouse gas emissions since 1990. Carbon dioxide emissions from passenger cars and light-duty trucks totaled 1,061.0 Click to enlarge.
US carbon dioxide emissions from fossil fuels decreased by 2.8% in 2008 to 5,802 million metric tons of carbon dioxide (MMTCO 2 ), down from 5,967 MMTCO 2 in 2007, according to preliminary estimates released by the Energy Information Administration (EIA). Total US energy-related carbon dioxide emissions have grown by 15.9%
A new study finds that the growth of carbon production from Chinese exports has slowed or reversed, reflecting a “new phase of globalization” between developing countries that could undermine international efforts to reduce emissions. The paper is published in Nature Communications. —Prof Guan.
The findings, published in the 21 September issue of Atmospheric Chemistry and Physics , are generally consistent with official Chinese government statistics and could bolster their credibility as international negotiations proceed on commitments of China and other nations to combat climatechange. Munger, J. McElroy, M. Nielsen, C.
EPA’s SmartWay Transport Partnership is a market-driven initiative that empowers businesses to move goods in the cleanest, most energy-efficient way possible to protect public health and reduce the emissions that contribute to climatechange.
The report’s authors, Max von Bismarck and Anuradha Gurung from the World Economic Forum, and Chris Greenwood and Michael Liebreich from New Energy Finance, argue that “ enormous investment in energy infrastructure is required to address the twin threats of energy insecurity and climatechange. billion) in 2004.
The results depend most sensitively on the grade of shale used, and the rate of carbonate mineral decomposition which causes inorganic CO 2 release, reports Brandt in a paper published online 25 August in the ACS journal Energy & Fuels. This project was terminated in 2004 due to cost overruns and opposition on environmental grounds.
The study judged that the potential CO 2 emissions reductions from low-carbon technologies within the next five years is “ quite low ” (around a 6% improvement), although in the longer term, i.e. between now and 2020, the potential CO 2 emissions reduction is much larger (up to 30% on a well-to-wheels basis).
These areas store 579 megatonnes (million tones) of biological carbon, mostly in peatlands. When the carbon in soils, peat and trees breaks down, it combines with oxygen to form carbon dioxide (CO 2 ). The above and below ground biological carbon content of this area is at least 140.7 megatonnes of carbon, 873.4
The latest analysis of observations from WMO’s Global Atmosphere Watch (GAW) Programme for 2008 shows that the globally averaged mixing ratios of carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O) reached new highs with CO 2 at 385.2 The globally averaged mixing ratio of carbon dioxide (CO 2 ) in 2008 was 385.2
X PRIZE’s Energy & Environment Prize Group intends to catalyze a new era of clean, renewable, cost-effective energy with minimal impact on the climate and environment. Areas of consideration include breakthroughs in climatechange, water resource management, energy distribution & storage, clean energy, energy efficiency/use.
These contributing factors included a decline in the carbon intensity of the energy supply (CO 2 /British thermal units [Btu]) of 1.7% Combining these two factors, the overall carbon intensity of the economy (CO 2 /GDP) declined by 3.1%. Although real gross domestic product (GDP) increased 1.5% along with a 1.4%
Total US greenhouse emissions were 6,673 million metric tons of carbon dioxide equivalent in 2013, an increase of 2% (127.9 MMT CO 2 in 2004, and since then have declined about 13%. ClimateChange Emissions' MMT CO 2 Eq.) Total US emissions have increased by 5.9% from 1990 to 2013. CO 2 emissions from LDVs totaled 1,028.0
The report, Inventory of US Greenhouse Gas Emissions and Sinks: 1990-2007 , is the latest annual report that the United States has submitted to the Secretariat of the United Nations Framework Convention on ClimateChange. Total emissions of the six main greenhouse gases in 2007 were equivalent to 7,150 Tg of carbon dioxide.
Key findings of the study include: Average soybean yield for the 2004-2007 time period was 42.35 bushels per acre, which represents a 12% increase over the data (1998-2000 average) used in the current US LCI database; Each bushel of soybeans harvested reduces greenhouse gases (carbon dioxide (CO 2 ) equivalents) by 32.6 kg (for the 3.36
It also showed that global annual emissions of greenhouse gases increased from 24 billion tonnes of carbon dioxide equivalents in 1970 to 33 billion tonnes in 1990 and 41 billion tonnes in 2005. Carbon dioxide showed the greatest growth, but levels of gases such as methane and nitrous oxide have also increased.
million metric tons of carbon dioxide equivalents, or 5,742.6 million metric tons of carbon dioxide equivalents after accounting for sequestration from the land sector. Between 1990 and 2004, average fuel economy among new vehicles sold annually declined, as sales of light-duty trucks increased.
World-wide “peak oil” production is expected to occur from 2010 to 2025+ (by some experts estimate that we have already reached peak production since 2004). The problem with conventional Fischer-Tropsch processes for the production of synfuels is their carbon intensity, and their being practical only for “ land-based operations.”
Green areas indicate waters supersaturated with aragonite carbonate and favoring shell formation, with darker color indicating more favorable conditions. However, when CO 2 dissolves in seawater, it forms carbonic acid. Projected spread of acidification of the oceans from 1994 (left) to 2100 (right). Monaco Declaration. Earlier post.).
By comparison, meeting Japan’s standards for 2004-2015 requires a 1.9% annual increase to 2015; and meeting China’s 2004-2009 target requires a 5.3% Ford recognizes the need for a comprehensive approach to the reduction of greenhouse gas emissions to address climatechange concerns. annual increase. Sue Cischke.
Those vertical movements provide a pathway for black carbon, sulfur dioxide, nitrogen oxides, and other pollutants to ascend into the stratosphere, about 20-25 miles above the Earth’s surface. The monsoon is one of the most powerful atmospheric circulation systems on the planet and it happens to form right over a heavily polluted region.
The Long Beach, CA-based truck/trailer emits 85% less overall particulate matter and 10% less carbon dioxide than its diesel counterparts. Since 2004, SmartWay Partners have saved 144.3 million metric tons of carbon dioxide; 1,070,000 tons of nitrogen oxides; and 43,000 tons of particulate matter. billion in fuel costs.
The study applied the NASA Goddard Institute for Space Studies (GISS) model for Physical Understanding of Composition-Climate INteractions and Impacts (G-PUCCINI). This model has been used previously to understand the role of short-lived air pollutants in climatechange for past, present and future atmospheres. Unger et al.
The declining increase in China’s emissions fits the trend since 2004, when its emissions increased by 17%. These changes reflect the large economic development in China, structural changes in national and global economies, and the impact of climate and energy policies. Tags: ClimateChange Emissions.
But in a year that has seen both a worsening recession and state budget crisis, residents’ support for urgent action on climatechange has slipped and a partisan divide on the issue has widened. But in the current economic climate their support has dropped a notch. Mark Baldassare, president and CEO of PPIC.
In the fall of 2010, California accepted compliance with these federal GHG standards as meeting similar state standards as adopted in 2004, resulting in the first coordinated national program. In April 2010, DOT and EPA established greenhouse gas emission and fuel economy standards for model year 2012-2016 light-duty cars and trucks.
Global efforts to combat climatechange hinge on pivoting sharply away from fossil fuels. kilograms in the 2004 Prius to about 0.5 Also, we needed to use a carbon-fiber-and-epoxy system to reinforce the outer diameter of the rotor to let it spin at speeds as high as 20,000 rpm. The dilemma is easy to describe.
In 2004, the Centralina region (the Greater Charlotte metro area, which straddles the North CarolinaSouth Carolina border) was designated as a non-attainment area for ozone under the Clean Air Act. They will offer much greater range and will be refueled as quickly as vehicles that run on petroleum products.
The Earth continues to experience record-breaking temperatures caused by increased atmospheric concentrations of carbon dioxide (CO 2 ) and other greenhouse gases (GHGs). US intelligence and defense agencies say such environmental changes can lead to energy insecurity, water and food shortages, and social instability.

In 2014, Volkswagen of America announced that starting with the launch of the zero-tailpipe emissions battery-electric 2015 e-Golf ( earlier post ), it would invest in projects to offset the carbon emissions created from the e-Golf on a full lifecycle basis: production, distribution and up to approximately 36,000 miles (57,936 km) of driving.
Bishop and Wood with a recent version of the Carbon Explorer float. Their study reveals that most of the carbon from lush plankton blooms never reaches the deep ocean. The results weaken the applicability of the simplest version of the Iron Hypothesis as a geo-engineering approach to climatechange. Click to enlarge.
The update identifies eight key sectors for ongoing action: Energy; Transportation, fuels, land use and infrastructure; Agriculture; Water; Waste management; Natural lands; Short-Lived Climate Pollutants (such as methane and black carbon); and Green Buildings. Low-Carbon Fuels. Background. —Draft Scoping Plan Update.
Attendees believe that renewable energy needs two elements to be successful: technical progress leading to lower costs and a price on carbon. They were hoping it was going to be more aggressive in combating carbon directly through a stronger cap and trade and indirectly with a higher federal renewable energy standard. Earlier post.).
Several dozen prototypes on 15-passenger van since 2004; now in second generation development; no production plans.
