Estimates direct emissions of carbon from Canadian forest fires for all Canada and for each ecozone for the period 1959?1999. Basis of the estimates on a data base of large fires for the country and calculations of fuel consumption for each fire using the Canadian Forest Fire Behaviour Prediction System; Fire locations and start dates to estimate prevailing fire weather and fuel type for each of about 11 000 fires; Mean area-weighted fuel consumption for all fires; Mean annual estimate of direct carbon emissions; Individual years, which ranged from 3 to 115 Tg C?year?1. results, including that these direct fire emissions represent about 18% of the current carbon dioxide emissions from the Canadian energy sector, on average, but vary from 2 to 75% among years. Conclusion that post-fire effects cause an additional loss of carbon and changes to the forest sink condition.
