Warning by IPCC Report
“CO2 emissions must be reduced by
85 - 50% by 2050 compared with the
2000 level to limit CO2 to 350 -400 ppm.
Even if we could do it, a temperature
rise of 2.0 – 2.4 ºC will be inevitable.”
Total CO2 Emissions from
Concrete Sector
Total: about 5.9 billion tons (Cement,
aggregate, steel, execution,
transportation)
It corresponds to 20% of the total
fossil fuel origin CO2 emissions,
which is 30.0 billion tones in 2007.
