I frequently think that the climate change solution is in transforming the power production sector and consumers mentality somehow. However, many times remember too that transportation is important and I got in mind the simple figure that one out of three CO2 tons comes from transport. Rough numbers help but it is always better to be more precise, and the two figures in this blog follow this purpose. They have been obtained with the open data from the Internationa Egergy Agency (IEA) and show total emissions in 2010.
The first one, at the beginning, displays the emission proportions by emission production sectors. In some cases, these divisions are not easy to understand but the main conclusion can be that electricity production is responsible for more than 40% of emissions and this is good news in my opinion because the progress in low-carbon electricity production has been much fester than in other factors and because in fact there are many countries producing most of their electricity without fossil fuels. Transport and industry account for other more or less 20% each (in industry excluding electricity use). Transport is a bit lower that the 33% that I expected and it is mainly road transport. Residential sector is surprisingly low.
In the other hand, the last figure classifies the same data by consuming sector. So roughly, industry is the objects we use, transport is transport and residential our houses. In this case, industry leads the figure with 36%, and transport and residential follow close to 20%.
The main reference is that we should reach 10-20% of current emissions to be on the safe side, so we have to make important effort in all areas.
