• Burning ethanol also releases large quantities of nitrogen oxide (smog) that causes respiratory disease.

  • The largest problem is the dangerous amount of nitrogen oxide (which mixes with vehicle-exhaust gas to create ozone, and then smog) coughed out by the state's industrial plants.

    ECONOMIST: The Lone Smog State

  • He was made aware of the concerns by a Cotswold councillor asking what could be done about high levels of nitrogen oxide (NO2) in the area off the A417.

  • What ails Modesto is what ails Bakersfield (No. 1), Hanford (No. 3), Fresno (No. 4) and other small Central Valley cities (the Valley accounts for all the California cites on the list aside from Los Angeles): heavy doses of nitrogen oxide and hydrocarbons stemming from gasoline, chemical processing, paints and other industrial byproducts that harm the ozone and release particle pollution into the air.

  • The new rule required about half the states to reduce their emissions of sulphur dioxide, nitrogen oxide and other emissions based on projections of how many pollutants were crossing state lines, and told them how to do it.

    ECONOMIST: Air pollution

  • The engine would use at least 25% less fuel and, he claims, its emissions of carbon dioxide and nitrogen oxide would be cut by three-quarters because of its unique ignition properties.

    ECONOMIST: A new way to build a greener jet engine

  • According to EPA, the levels of sulfur dioxide and nitrogen oxide would have been cut in half under the cross-state rule.

  • The report analyzed data for 2010 and found in that year that emissions of sulfur dioxide and nitrogen oxide were 68% lower than in 1990 and had fallen 32% and 31% respectively just since 2008.

    FORBES: Coal-Fired Carbon Emissions Fall As Transition To Cleaner Energy Accelerates

  • The result, when it is burned, is the near-complete abolition of soot, and a reduction of up to 80% in nitrogen-oxide emissions.

    ECONOMIST: To make engines cleaner, add H2O

  • He's known for performing "cryosurgery"--a form of surgery that uses liquid nitrogen or nitrous oxide to freeze off cancerous tumors rather than cutting them out or amputating the host limb.

    FORBES: Miracle Worker

  • Fuel cells offer several advantages: they do not have moving parts and there is no burning involved, so there are negligible emissions of environmentally harmful gases like nitrogen, sulfur oxide and carbon monoxide.
