Global GHG emissions have increased over the last century and most forecasts suggest that this will continue unless aggressive action is taken to reduce emissions. Developed world countries such as the United States and those in the European Union are major emitters of GHGs, but a new and challenging dynamic is the GHG growth occurring in developing economies such as China, Brazil, and India.
Between 1990 and 2005, global emissions increased by approximately 18% to over 41,132 MT. In that time, China doubled its emissions to over 7,200 MT and surpassed the U.S. as the world’s largest emitter, growing from 10% of global emissions to 18% - the U.S. is responsible for approximately 17%. China, along with other advanced developing countries including Brazil, Russia and India, accounted for approximately 29% of global emissions in 2005 - up from 24% in 1990.
Canada is responsible for approximately 1.8% of global emissions, but it has experienced some of the highest GHG growth rates in the world. Between 1990 and 2005, GHGs in Canada grew more than the global average with an increase of 26.2%.
Newfoundland and Labrador’s GHG emissions are approximately 10.5 MT, which accounts for 1.4% of total emissions in Canada. Approximately half of the province’s emissions come from the energy and energy-intensive sector, which includes oil extraction and refining, mining operations, pulp and paper and electricity generation. The transportation sector is also a major source of emissions in the province, currently accounting for one-third of emissions.
