Global carbon emissions from fossil fuels increase by 49% in 20 years

A recent report from an international research team shows that over the past 20 years, carbon emissions from global fossil fuels have increased by 49%. If this trend develops, the emission reduction targets set in the "Kyoto Protocol" will be difficult to achieve. Related papers were published in the "Nature Climate Change" magazine published that day.

The study, which was conducted by the Norwegian Center for International Climate and Environment Research and the British Tyndall Climate Change Research Center, said that the carbon emissions from global fossil fuels increased by 9% in 2010, and the Kyoto Protocol determined that The base year from 1990 to 2010 increased by 49%. From 2000 to 2010, fossil fuel emissions increased by an average of 3.1% per year. This growth rate was three times that of 1990 to 2000. Researchers expect that carbon emissions from fossil fuels will remain at least 3.1% in 2011.

According to the report, the carbon emissions currently generated mainly come from the burning of fossil fuels, cement production, deforestation and other land use. Half of the emissions are left in the atmosphere and the remaining emissions are absorbed by the oceans and land. This brings the carbon dioxide concentration to 389.6 ppm. Before industry**, this value was only 280ppm.

The researchers said that this has relations with emerging markets and developed economies. Although much of the increase comes from emerging economies, in the current world economic system, many of the carbon emissions generated by the production of goods and services are in emerging economies, while their consumption is in developed countries in the West. Rich countries continue to transfer part of their emissions to emerging economies through international trade outsourcing.

Dr. Glan Peters of Norway's Center for International Climate and Environment Research, which is responsible for the study, said that many people thought that the financial crisis could provide an opportunity for the global economy to stay away from high-emission growth, but carbon emissions in 2010 will be renewed. Growth makes this idea fail.
