CO2e emissions from production
There was an improvement across most business lines on emissions of CO2e per tonne of product, both compared to 2017 and to the 2010 baseline. This was due mainly to a reduction in the carbon intensity of grid electricity, which represents 13.5 per cent of total energy consumption and shifts in some business lines to lower carbon intensive fuels, for example gas at our asphalt plants. However, total emissions of CO2e per tonne of product rose in line with energy consumption and is running at 7.9 per cent above our 2010 baseline. When the data is normalised to the same product mix as 2010, there has been a reduction of 9.7 per cent.
We are working with three universities – Reading, Cambridge and Swansea – on carbon reduction projects for our cement and Regen plants which have the potential to save over 50,000 tonnes of carbon annually. We are also investigating a number of additional collaborative research projects to reduce our carbon footprint.;
