After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide. The gas is produced primarily during the combustion of gasoline in vehicle engines and coal in power plants.

After a thorough scientific review ordered in 2007 by the US Supreme Court, the US Environmental Protection Agency (EPA) issued a proposal with two distinct findings regarding greenhouse gases. Combined with the endangerment finding, this enables the regulation of greenhouse gas emissions from motor vehicles under the Clean Air Act.

After a thorough scientific review was ordered by the US Supreme Court in 2007, the Environmental Protection Agency (EPA) has issued a proposal on greenhouse gases. It has been deemed by the EPA that the emissions from new motor vehicles and their engines contribute to these concentrations and threaten climate change.

The Brazilian experience shows that the presence of small (<10%) amounts of water in the fuel does not in itself cause a greater tendency to misfire in spark ignition engines than a proportionate leaning of the fuel/air mixture would do, provided that the vapor pressure of the hydrated ethanol at the ambient temperature is high enough.
