The media reports China has “pledged” to
reduce CO2 emissions by 2030 in a letter to the UN Climate bureaucracy.
However, it looks like China´s reduction pledge is a sizable increase, and
would leave China as the King Kong of CO2 emissions per capita and by just any
other unit we wish to use.
Chinese citizens are very happy to see the new
government plans to increase CO2 emissions, thus
ensuring the people´s future economic well being.
Su Wei, has pledged to increase China´s CO2 emissions
by 2030 by an unspecified amount. Mr Su
is the “National Focal Point for UNFCC”
and Director General of the Department of Climate Change. He sent a letter to Christiana Figueres , UNFCC Executive Secretary, stating China would lower carbon dioxide
emissions per unit of GDP by 60% to
65% from the 2005 level.
Note: If you don´t like math please skip the following paragraph.
So how much CO2 are we talking about, and is
this letter saying China will increase or decrease CO2 emissions? It depends.
Su reports in his letter (on Pg 3) than
China´s CO2 emissions per GDP unit have already dropped by 33.8 % from the 2005
level. Chinese 2014 emissions were around 10 gigatons (that´s 10 X 109),
and GDP was 17617 X 109 US
Dollars in 2014. This means Chinese CO2 emissions intensity was (10/17.617)
0.567 kg per $ in 2014, and 0.856 kg per $ in 2005…this is getting nerdy....We´ll use Mr. Su´s figures to figure out what´s going on. If China drops it´s CO2 intensity by 62 %
from the 2005 figure the 2030 value would be (1-0.62) times 0.856 kg per $, or 0.325 kg CO2 per $.
China´s economy will grow by X amount between
2015 (now) and 2030 (the target date). We don´t know how much it will grow, but
we can try to make a guess. The World Bank, in it´s "China 2030" report showed
the following:
World Bank´s China Growth Projections to 2030
Note: If you don´t like math please skip the following paragraph.
They project China´s economy will be 2.37 times
larger by 2030. I´m going to be a bit less optimistic and cut it down to 2. If
China´s economy doubles to $35200 X 109
US Dollars by 2030, and emissions intensity drops to 0.325 kg CO2
per $, then China´s CO2 emissions would
be 11.4 gigatons. If the growth is as projected by the World Bank they could be
13.5 gigatons.
In conclusion, Mr Su´s
letters says China plans to increase its CO2 emissions by 2030.
Note: If you don´t like math please skip the following paragraph.
By comparison, today´s European Union CO2
emission intensity is around 0.3 kg CO2 per $. This means the Chinese have
committed to decrease its 2030 emissions
intensity to a value slightly higher
than the European Union´s before it commits economic suicide and atempts to cut its emissions by a further 20 % from 2020 to 2030. Meeting this pledge
would drop its emissions intensity to 0.2 kg per $ if its economy manages to
grow 1 % per year.
Note: You should read this paragraph even if you don´t like math
And that´s it in a nutshell. The European Union
plans to drop its CO2 intensity to 0.2 (or even lower), China plans to drop its
CO2 intensity to 0.325 kg per $. China will be the undisputed CO2 champion in 2030, and school children all over the world will be learning Chinese as a second language.
