Does ENTONOX pollute the environment?

Like carbon dioxide and methane, nitrous oxide is a gas which contributes to the global warming effect.

Nitrous oxide has a Global Warming Potential (GWP) of 265 according to GHG Protocol AR5. BOC have a continuing focus on the environmental emissions from our Nitrous oxide and Entonox operations and we strive to reduce these wherever possible. BOC continue to assess our nitrous oxide and ENTONOX filling processes to identify opportunities for improved practices and efficiencies that further reduce our carbon footprint.

Nitrous oxide is mostly produced from agriculture, fertilisers, animal waste and industrial production. Medical use represents a small contribution, less than 1% of total global nitrous oxide emissions (1, 2) compared to livestock which contributes 65% and manufacturing industries which contributes 20%.
