Climate change

Bellway recognises the significant effect carbon emissions have on the climate and as a responsible organisation we seek to actively manage this risk on an ongoing basis.

We measure our carbon footprint based on the UK Government’s Environmental Reporting Guidelines (2013) and the latest emission factors from the Government’s GHG Conversion Factors for Company Reporting. We have our footprint independently verified to a ‘reasonable assurance level’ and all emissions are included apart from:

  • Gas and electricity from part-exchange properties due to immateriality and difficulty in accurately reporting and recording this data.
  • Emissions from site-based combined heat and power units for which the Group does not have operational control.
  • We continue to communicate our carbon performance to our stakeholders, both within our annual report and accounts and through our participation in the Carbon Disclosure Project (CDP).
Summary of performance
25,832 tonnes of carbon emissions were produced (2017 – 24,909)
2.5 tonnes of carbon emissions per home construction were produced (2017 – 2.6)
9.2 tonnes of carbon emissions per Bellway employee were produced (2017 – 9.8)
100% of compounds were fitted with energy saving devices (2017 – 94%)
3,802 homes incorporated renewable and energy saving technology (2017 – 3,723)
Homes constructed in the year achieved an average dwelling emission rate (DER) of 5.0% better than building regulations (2017 – 6.0% better)
A behavioural energy saving campaign has been rolled-out to all 22 regional offices
Greenhouse gas emissions (tonnes C02e)1  2018 2017

Scope 2 emissions have been reported using the location-based method but we have also provided a market-based method for transparency

Based on number of legal completions

Based on the average number of employees during the year

An element of carbon estimation is undertaken in the following areas:

  • Diesel fuel usage on a small number of sites where fuel is provided by our groundworks contractors. Bellway’s share of the usage is estimated based on forklift usage.
  • Divisional offices where gas and electricity usage is included within landlord charges. Bellway’s usage is estimated using a kwh per square meter of occupied floor space figure derived from other divisional offices with utility billing in place.

Our overall carbon emissions have increased by 3.7% to 25,823 tonnes CO2e (2017 – 24,909). This has largely been driven by an increase in construction activity, with the number of homes sold increasing by 6.9% to 10,307 (2017 – 9,644). It should be noted that the 2017 GHG Conversion Factors have seen a 15% decrease in the UK electricity CO2e factor (location based) compared to the previous year. This is due to a significant decrease in coal generation, and an increase in gas and renewables generation, for UK electricity in 2015 (the inventory year on which the 2017 GHG Conversion Factor is based). This has led to our Scope 2 emissions from electricity consumption falling by 3.4% even though usage has risen by 13.2%.

Reporting via business metrics, carbon emissions per home sold have decreased by 3.0% to 2.5 tonnes (2017 – 2.6) and carbon emissions per employee have fallen by 10.4% to 9.2 (2017 – 9.8). Both the 2017 and 2018 emissions have been externally verified by Zeco Energy to a ‘reasonable assurance level’.
