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
25,715 tonnes of carbon emissions were produced (2018 – 25,253)*
2.4 tonnes of carbon emissions per home construction were produced (2018 – 2.5)
8.6 tonnes of carbon emissions per Bellway employee were produced (2018 – 9.0)
100% of compounds were fitted with energy saving devices (2018 – 100%)
3,926 homes incorporated renewable and energy saving technology (2018 – 3,802)
Homes constructed in the year achieved an average dwelling emission rate (DER) of 4.5% better than building regulations (2018 – 5.0% better)
We now purchase electricity from renewable sources to power our development compounds:
  • 961 tonnes of carbon saved from entering the atmosphere this year
  • carbon from electricity has reduced by 2.5%
  • overall carbon per home sold has fallen for the first time by 4%

* Our scope 2 emissions are now reported using the market-based method to account for electricity supplies purchased under REGO contracts. Scope 2 emissions for 2018 have been restated using the same methodology

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 only 1.8% to 25,715 tonnes CO2e (2018 – 25,253), against a 5.7% increase in homes sold to 10,892 (2018 – 10,307). This smaller increase in carbon, compared to construction growth, has been driven in part by our switch during this year to procuring site compound electricity from renewable sources through Renewable Energy Guarantee of Origin (‘REGO’) backed supplies. For the current year this has saved 961 tonnes of carbon from entering the atmosphere and helped us reduce carbon from our electricity usage by 2.5%, despite usage increasing by 16.9%.

Reporting via business metrics, overall carbon emissions per home sold have decreased by 4.0% to 2.4 tonnes (2018 – 2.5) while carbon emissions per employee have fallen by 4.4% to 8.6 tonnes (2018 – 9.0). Both the 2017/18 and 2018/19 emissions have been externally verified by Zeco Energy to a ‘reasonable assurance level’.
