What do I think, What can I do?

In the world the CO2 emissions corresponding to the transport sector sum a 22% of the total.

Nonetheless this percentage varies seriously from country to country. Among the top emitters (next table), China and India do not reach the 10% emissions by transport, Germany and Japan are close to 18%, the USA are around 26% and some like Mexico or  Brazil are above 35%. So transport is very important depending on the location.

Transport Emissions Road Emissions
People’s Rep. of China 7.04% 5.48%
United States 30.21% 26.09%
India 9.93% 8.90%
Russian Federation 15.30% 8.85%
Japan 19.48% 17.59%
Germany 19.11% 18.51%
Korea 15.41% 14.52%
Canada 31.62% 26.02%
Islamic Rep. of Iran 23.31% 23.07%
United Kingdom 24.67% 22.90%
Saudi Arabia 23.42% 22.93%
Mexico 36.31% 35.34%
Indonesia 25.75% 22.59%
Italy 27.13% 25.58%
Brazil 42.82% 38.22%
Australia 21.44% 18.01%
France 34.56% 33.06%
South Africa 11.01% 10.23%
Poland 15.34% 14.99%
Chinese Taipei 13.12% 12.69%
Spain 36.42% 31.73%

Next histogram includes the distribution of these topo emitters but also the whole world, and in this case the panorama is even more complex with a range from less than 10% of the share until more than 90%.

Anyway, one thing is quite regular for all of them road is the main transport emission source, a 16% around the world but up to 80% in Congo or 35% in Mexico.

Meanwhile, americans are driving less, (reducing that 26%) some also talk about peak car thereOne thing is clear, if we want to mitigate climate change, we will have to drive less (mas transit, bicycle, or just walk), do it more efficiently or change cars technology or all at the same time. In some cases it is not difficult to start saving CO2.

  1. […] Finally, electricity can be the way to decarbonize other sectors as transport (the road is the most important contributor there) […]

  2. […] And how is it doing in China? I am not an expert and see news of both sides. In one part, they are burning half of the coal of the world, if they do not stop we will get quite hot.In the other hand there are signs for hope as most Chinese are convinced of the importance of climate change, they want to be more active in renewables and form part of International Renewable Energy Agency (IRENA) and even if their 6 ton per capita emissions per year are not far from many European countries (but far from the USA), they burn them in part to produce goods that export. Transport emissions are low for example. […]
