Six greenhouse gases are reported on: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulphur hexafluoride.
He said improved security systems would be installed around the health board's nitrous oxide stocks.
The bus emits much less hydrocarbons, nitrous oxides and particulate matter than diesels, Fletcher said.
About 40% of the nitrous oxide emitted is from human activity, according to WMO estimates.
AstraZeneca has doped its version of a COX-2 inhibitor with nitrous oxide--laughing gas--to soften the gastrointestinal blow.
Nitrous oxide isn't the only dangerous substance teens are turning to for a quick and cheap high.
The team has found many public posts that target teens and advertise alcohol and illegal drugs such as nitrous oxide.
Carbon dioxide, methane and nitrous oxide were now more prevalent in the atmosphere than at any time since the industrial revolution.
This would lessen the need to burn coal and oil, and lead to reduced emissions of carbon dioxide and nitrous oxide.

Nitrous oxide has also been linked to a small number of fatalities.
The EPA, along with individual states, now regulates pollutants like hydrocarbons, particulate matter and nitrous oxides that are produced by cars and trucks.
Unlike hybrids, even newer diesels run afoul of emissions laws because they produce more particulate matter and smog-forming nitrous oxide than gasoline engines.
The latest data from the WMO also shows that emissions of nitrous oxide are 20% higher than in the preindustrial era, and are accelerating.
Concentrations of nitrous oxide, estimated to be nearly 300 times more potent than carbon dioxide, rose slightly to a record 324 parts per billion.
The FDA has recently focused on the illegal use of nitrous oxide, and this was its largest case to date, said special agent Lisa Hartsell.
Police in the Borders are investigating the possibility that boy racers may have been behind a spate of thefts and attempted thefts of Nitrous Oxide.
As fuel it uses liquid nitrous oxide and solid polythene plastic.
Nitrous Oxide is an anaesthetic normally found in hospitals and dentists.
The greenhouse gases surveyed include not only carbon dioxide but also methane (CH4), nitrous oxide (N2O), ozone (O3), and fluoride-containing gases that contribute to climate change.

The Advisory Council on the Misuse of Drugs is also calling for greater public awareness of the dangers of laughing gas - nitrous oxide - and helium.
In early-stage human trials in May 2000, scientists observed 66% fewer stomach erosions in 31 patients treated with a nitrous oxide version of a COX-2 inhibitor versus naproxen.
This simple move, documented in a U.S. Department of Energy report will cut emissions of carbon dioxide, sulfur dioxide, nitrous oxide and other emissions significantly while reducing costs.
The Swiss-based United Nations agency, which uses data from more than 50 countries to compile the report, also detailed rises in other greenhouse gases including methane and nitrous oxide.
Moreover, soil containing biochar releases less methane and less nitrous oxide than its untreated counterparts, probably because the charcoal acts as a catalyst for the destruction of these gases.
ECONOMIST: Biochar could enrich soils and cut greenhouse gases as well
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.
Los Angeles County sheriff's officials have zeroed in on the recreational use of nitrous oxide since September, cracking down on more than 350 illegal parties, spokesman Mike Parker said Thursday.
For example, in my company we're making 30% more electricity than we were in 1990, and we're doing it with about 40% less emissions of sulfur dioxides and nitrous oxides.
This will allow truckers to reduce emissions significantly (diesel emissions include nitrous oxides, particulate matter, and other air toxics and they are a major source of pollution in some areas).
In 2009, authorities spoke with the Valencia brothers and owner William Victor about their sales of nitrous oxide and its popular use as a party drug, according to a federal affidavit.
Nitrous oxide, emitted into the atmosphere from natural and man-made sources, including biomass burning and fertiliser use, was 323.2 parts per billion in 2010 - 20%higher than in the pre-industrial era.
