Keller is committed to minimising its impact on the environment and complying with its statutory and regulatory obligations.

Greenhouse gas reporting

Here we report the quantity of greenhouse gas (GHG) emissions for the year ended 31 December 2015. We have adopted the International Greenhouse Gas Protocol Corporate Accounting and Reporting Standard. In doing so, we have fulfilled our requirements concerning GHG emissions under The Companies Act 2006 (Strategic Report and Directors’ Report) Regulations 2013 No.1970.

Reporting boundaries

To the best of our knowledge, we have included all material emission sources which fall within the boundaries of our consolidated accounts.

All direct (Scope 1) and indirect (Scope 2) emissions are reported in absolute tonnes equivalent CO2. GHG included are carbon dioxide, methane and nitrous oxide emissions from the combustion of fuels mentioned below, and carbon dioxide emissions from the consumption of purchased electricity:

  • Scope 1 – Direct GHG emissions: combustion of diesel, petrol, gas, oil and LPG.
  • Scope 2 – Indirect GHG emissions: purchased electricity consumed.

Data gaps and exclusions

Since adopting the International Greenhouse Gas Protocol Corporate Accounting and Reporting Standard in 2013, we have worked on improving the coverage and accuracy of the reporting. This is an ongoing exercise and for the second year running the number of data gaps has reduced.

Last year 98% of units within the Group reported some data. This year all units reported some data on their primary emission sources, including entities acquired during the year 2015. We have accounted for these new acquisitions in our calculation of the 2015 footprint. Units also report more complete datasets than last year – more fuels reported and better coverage for the whole year.


Summary Scope 1 and 2 GHG emissions for the Keller Group are shown below for 2014 and 2015.

Global GHG emissions data in tonnes of CO2e

Emissions from: 2015 2014
Scope 1 – Combustion of fuel and operation of facilities 168,392 170,031
Scope 2 – Electricity, heat, steam and cooling purchased for own use 9,032 9,531
Total 177,424 179,562
Intensity measurement: Absolute tonnes equivalent CO2e per £m of revenue 114 112

Our total footprint for the year 2015 has decreased by 1.2%, broadly in line with the Group’s reduction in revenue. However, our carbon intensity has increased by 1.2%, from 112 to 114 tonnes CO2e per £m of revenue. This increase is due to a number of factors including more complete reporting.

Third-party assurance statement

“Based on our review, we are not aware of any material modifications that should be made to Keller Group plc’s assertion that their Scope 1 and 2 group inventory is in conformance with the requirements concerning greenhouse gas emissions under The Companies Act 2006 (Strategic Report and Directors’ Report) Regulations 2013 No.1970, following the methodology of the Greenhouse Gas Protocol Corporate Accounting and Reporting Standard.”
