Climate and energy

Cement production industry makes up to 5% into worldwide CO2 emission due to anthropogenic factors. Globally, potential for cement industry emission reduction is estimated as 450 million tonnes of CO2/year. As for Russia it is about 20-25 million tonnes of CO2/year, which is approximately 1% of its greenhouse gas emissions.

From the point of view of specific emissions reduction, Russia’s potential is 0.39 tonnes of CO2 /t of cement, which is twice higher than in the world. Potentials of Canada, the U.S., China, Korea and Brazil are within 0.19 - 0.25 tonnes of CO2 /t. In comparison Japan can reduce emissions by 0.06 tonnes of CO2 /t, yet developed European countries by 0.09 tonnes of CO2 /t.

In Russian cement industry the greatest contribution into greenhouse gas emissions reduction could be made due to shift from "wet" production process to "dry." (See project of reconstruction and modernization of Holcim plant in Kolomna).

Also emissions reduction is possible due to energy economy. According to experts, cement production industry is one of the three most energy intensive sectors of global economics. In production process 20 to 40% of all costs are energy costs.

dry process, ~3 GJ/t semi-dry process, >3 GJ/t wet process, >6 GJ/t
China 47,1 50 0 3
India 6,1 50 9 25
USA 3,9 82 0 18

Specific emissions from cement production in different countries

As we see from the table, Russia is behind other countries in energy efficiency and has the unique opportunity to shorten this gap.
