CO2 Emissions Production

The indicator for production CO2 is carbon intensity or CO2/tonne of concrete produced. Data from the energy use of concrete production and a proportional contribution from constituent materials are converted to carbon emissions using factors published by DEFRA with an adjustment for the process carbon emissions from cement. The resulting value of the indicator is influenced by both CO2 emissions from production and changes in the average proportions of concrete represented by the data collected. These proportions, termed the "Rolling mix" are directly affected by the relative market demand for different types of concrete.

Performance indicator

CO2 emissions - Production (Rolling mix) (kg CO2/tonne)

In 2016 the Rolling Mix value was 82.8 kg/tonne for concrete (24.2% reduction from 1990 baseline) and 90.1 kg CO2/tonne for concrete + reinforcement.

Performance indicator

CO2 emissions - Production (Standardised mix) (kg CO2/tonne)

The Standardised or Baseline mix is based on the average proportions of materials in concrete when the strategy was launched in 2008. By using these fixed mix proportions with each year’s carbon values, the industry reports the overral carbon intensity and shows the performance directly under its control. In 2016 the standardised mix value was 73.7 kg CO2/tonne for concrete (28% reduction from 1990 baseline) and 81.7 kg CO2/tonne for concrete + reinforcement.
 
The 2020 target is to reduce CO2 emissions by 30% from the 1990 baseline equivalent to a value of 72.2 kg CO2/tonne of concrete produced.

These indicators are part of the Carbon section of the report and 2020 Strategy Commitments. An update on our Carbon commitments.
