Data notes:

The emissions in each category are explained below:

  • Purchased fuels: Indirect emissions associated with the extraction and transport of primary fuels as well as the refining, distribution, storage and retail of finished fuels.
  • Water supply and treatment: Emissions of greenhouse gases associated with the supply and treatment of water and the industry's buildings and transport.
  • Employee business travel: Emissions associated with the production and use of fuel for transporting employees for business purposes; this category includes all business mileage, air travel and rail travel.
  • Product distribution: Emissions associated with the production and use of fuel for transporting products; this category includes distribution by road and rail of all products from the quarry materials business.
  • Waste disposal to licensed landfill: Emissions associated with the disposal of waste to landfill; 'mixed commercial and industrial waste' factors are used in the absence of more specific data. This includes the waste sent to licensed landfill from our recycling business.
  • Landfill emissions: Emissions associated with the flaring of methane from landfill sites owned and operated by Tarmac's quarry materials business. The figures are estimated according to gas pumping rates and typical methane concentration.

Data notes:

  • Includes direct emissions from process emissions and combustion of fossil fuels and waste-derived fuels, excluding biomass, indirect emissions from electricity.
  • Reported figures are carbon dioxide equivalents and account for the impact of the emission of other greenhouse gases; this is a more complete reporting method but gives slightly higher results than kgCO2/t.
  • Annual data reported as December to November.
  • Cement and lime data excluded for reasons of commercial confidentiality.
  • Sand and gravel data includes land won, wharfs, Tarmac Marine Dredging (TMD) and sand drying; figures have been updated to reflect more accurate data capture.
  • Land won sand and gravel emissions = 4.04 kg CO2e/tonne.
  • The percentage specific carbon emissions reduction figure quoted in the report includes all products and energy, so is different to the data set above, which is provided for comparison with the industry.
