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.
It, or a scaled-up version, could also provide a solution for the Asian motor vehicle fleet, in which two-stroke engine vehicles constitute a major share—and contribute significantly to air pollution. —Faiz and Gautam (2004). ASME ICEF2012-92047). 2004.003891.
Since 2004, SmartWay Partners have avoided emitting more than 72 million metric tons of carbon pollution, while saving more than 170 million barrels of oil and $24.9 SmartWay also contributes to cleaner air and healthier citizens by cutting emissions that help produce smog, including fine particulate matter and nitrogen oxides.
GTL transportation fuel is cleaner burning than conventional diesel with a roughly comparable, and potentially lower, greenhouse gas profile, Sasol says. GTL fuels are virtually free of sulfur and aromatic compounds and reduce emissions of particulates, nitrogen oxides, carbon monoxide and other pollutants and will improve air quality.
A team of atmospheric scientists and environmental engineers from Harvard University and Tsinghua University in Beijing have continuously measured atmospheric CO 2 and carbon monoxide (CO) levels in rural Miyun, about 100 km northeast of Beijing, since November 2004.
While current state and federal measures are on target to reduce toxic diesel locomotive emissions 65% or more by 2020, additional measures recommended by ARB staff would ultimately provide up to 85% or greater emissions reductions within the rail yards over the same period, resulting in cleaner air for nearby residential neighborhoods as well.
In an effort to reliably predict efficiency and pollutant emissions for new engines and fuels, computer simulations are used to study fundamental turbulence-chemistry interactions. Low emission, low temperature engine concepts of the future operate in regimes where combustion is poorly understood.
For example, in 2004 they posed as representatives of Dow Chemical and promised that the company would clean up after the Bhopal Disaster, leading to a temporary $2 billion drop in the company’s market cap. Here are some examples of conversations we had with the tool: Frankly… it kind of feels like visiting a traditional car dealer.
Cold starts mean more pollution. The catalytic converter that keeps the ICE from being a gross polluter in conventional cars and hybrids however, isn't kept warm by the continual embrace of an ever-churning engine in a hybrid with all-electric range.
2 Plug-in hybrids are cleaner 3 Plug-in hybrids are cheaper 4 Plug-in hybrids are domestic 5 Plug-in hybrids already exist 1. So youll have a cleaner, cheaper, quieter car for your local travel, and the gas tank is always there should you need to drive longer distances. What Are Plug-In Hybrids? You dont have to plug it in.
Catalytic converters, along with so-called leak-proof emissions systems, are the primary reason why today’s cars are so much cleaner than those of several decades ago. Consequently, gasoline-power vehicles pollute the most when the engine is first turned on in the morning after being off for many hours.
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. Transportation. Transportation, Land Use, and Housing.
Stronger protection reduces the risk of opportunistic behavior by the licensee (Merges, 1998; Arora and Merges, 2004) and reinforces the licensor’s bargaining power, which enables him to appropriate a larger share of the total surplus generated by the licensing deal. Obstacles to Licensing. Sheehan (2006), STI Working Paper, OECD.
