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.
A study by the University of California, Riverside College of Engineering Center for Environmental Research and Technology (CE-CERT) found that a Los Angeles County Metropolitan Transit Agency (Metro) bus equipped with an ultra-low emission natural gas engine performs significantly cleaner than its certification standards across all duty cycles.
The US Department of Transportation (DOT), the US Environmental Protection Agency (EPA) and the state of California have announced a single timeframe for proposing fuel economy and greenhouse gas standards for model year 2017-2025 cars and light-duty trucks. The EPA standard would be equivalent to 35.5 Earlier post.) mpg US (6.9
A minimum cetane number is specified in the ASTM standard that defines the quality of diesel fuel sold in the United States. Values in the previous compendium (published in 2004) derived from octane numbers have been removed and replaced with a brief analysis of the correlation between cetane numbers and octane numbers.
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.
The two ecoDemonstrators will build upon the 2005 Quiet Technology Demonstrator (QTD2) program that helped both the Boeing 747-8 and 787 Dreamliner exceed international standards for noise emissions. Announced in 2010, the Boeing ecoDemonstrator Program is intended to reduce entry-to-market risk for new aviation technologies.
Drop-in alternative fuels will require no significant modifications to aircraft and engines and with a goal of performing more efficiently, and cleaner than current fossil-based fuels. Safety and transition strategies that enable “drop in” replacement for petroleum-derived aviation fuels.
The automakers, including Toyota, that are not interested in rushing to market with plug-in cars never tired of suggesting that conventional gasoline-only hybrids are cleaner than plug-ins. UPDATE: Felix Kramer of Calcars informs me that the vacuum bottle is standard on 2004-2008 Prius.)
Electrolux, based in the United Kingdom, introduced a prototype of its Trilobite robotic vacuum cleaner in 1997, and at iRobot in Boston, Joe Jones was working on what would become the Roomba. In 1996, Honda showed off its P2 humanoid robot, a prototype of the groundbreaking ASIMO , which would be unveiled in 2000.

Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. Major transportation related policies already in place are: The Low Carbon Fuel Standard (LCFS). Background. —Draft Scoping Plan Update.
Developing nations, China adds, should not be restrained in using economic development to raise their standards of living, even if greater emissions result. Notably, pieces of knowledge being all different from each other, there is little standardization, making it difficult to have references such as common price or standard contracts.
IBM's essential contributions were to position the technology as suitable for wide use and to set a technology standard. IBM's strategic error in not retaining rights to the operating system went far beyond that $27 billion; it meant that Microsoft would set the standards for the PC operating system. Lowe was aghast at that strategy.
Despite receiving healthy amounts of praise for offering novel designs that were praised as cleaner to operate and easier to maintain than combustion models, the company went defunct in 1914. However, much of its novel features have become standard equipment on many modern automobiles.

When the air resources board relaxed its rules in 2003, it allowed car companies to receive credits toward zero-emission standards by building so-called partial-zero-emissions vehicles — super clean cars that produce little or no smog. 3Prong Power only works on Prius model years 2004 to 2009.
