25% emissions from coal
Coal is the main cause of global greenhouse gas emissions. A quarter of the emissions is because of the worldwide coal combustion.
World Resources Institute concluded this out of their latest calculation.
The calculation is an updated version of a flowchart showing the global greenhouse gas emissions. The diagram can be seen from beginning to end where greenhouse gases come from and how much of each gas ends up in our atmosphere.
The last time the flow chart was updated was in 2013. At that time, World Resources Institute used data from 2010. The updated version of the flow chart was created with data from 2012. The global greenhouse gas emissions grew in that period: from 48,629 mega tonnes in 2010 to 51.840 mega tonnes in 2012.
The flowchart also envisions which sectors contribute most to greenhouse gas emissions, including their sources. Burning coal is the most polluting form of energy production: 25% of all greenhouse gases is from coal. Within the built environment a large share of emissions is because of coal combustion.
Industry biggest polluter
Compared with the old one is from the new flowchart clear that the proportion of CO2 from fossil fuels and industrial processes with 2% increased to 67% in total. 29% of which consists of emissions of the industry, from the combustion of fossil fuels and industrial processes. Half of the emissions from combustion of fossil fuels comes from coal combustion. Industry thus makes the largest contribution to global warming.
Trees are also releasing CO2. The flowchart shows that emissions from deforestation in 2013 amounted to almost 8%. That is a reduction compared to 2010, when deforestation was responsible for over 10% of total global greenhouse gas emissions.
World GHG Emissions Flowchart was launched in 2000 by the World Resources Institute, a leading research center for policy specializes in raw materials and the environment. For the first time it is clear how much gas was actually emitted and who was responsible. Since then, the flow chart is one of the most commonly used charts to provide insight into greenhouse gases and climate change.
