"Annual methane emissions from abandoned oil and gas wells might be underestimated by as much as 150 per cent in Canada and 20 per cent in the U.S., according to a recent study from McGill University.
Methane is a powerful greenhouse gas that traps over 70 times more heat over a 20-year period than an equivalent amount of carbon dioxide. In Canada, the oil and gas sector is the largest industrial polluter of methane emissions in Canada.
Although abandoned wells contribute only one to four per cent of all methane emissions from the oil and gas sector annually, that amount is equivalent to the CO2 emitted by Newfoundland and Labrador each year."
