Climate change


  • 24,909 tonnes of carbon emissions were produced (2016: 22,334)
  • 2.6 tonnes of carbon emissions per home construction were produced (2016: 2.6)
  • 9.8 tonnes of carbon emissions per Bellway employee were produced (2016: 9.4)
  • 94% of compounds were fitted with energy saving devices (2016: 84%)
  • 3,723 homes incorporated renewable and energy saving technology (2016: 3,351)
  • Homes constructed in the year achieved an average dwelling emission rate (DER) of 6.04% better than building regulations (2016: 5.67% better)
  • An energy saving campaign was trialled in 3 divisions

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 11.5% to 24,909 tonnes CO2e (2016: 22,334). This has largely been driven by an increase in construction activity, with the number of homes sold increasing by 10.6% to 9,644 (2016: 8,721). Using our chosen business metrics, carbon emissions per home sold has remained consistent with the previous year at 2.6 (2016: 2.6) and carbon emissions per employee have risen by 4.3% to 9.8 (2016: 9.4). Both the 2016 and 2017 emissions have been externally verified by Zeco Energy to a ‘reasonable assurance level’.

Performance Against 2016/17 Target

We will develop quarterly carbon reporting with a view to establishing carbon reduction targets in future years

Carbon data is now collated on a quarterly basis and in 2018 further analysis will be undertaken to establish a cost of carbon measure, identify opportunities for savings, roll-out best practice and consider potential carbon reduction targets


2017/18 targets

For the 2017/18 Bellway financial year, we have set a range of targets across our three CR themes (Environment, Construction, and Society and Economy). We have prioritised these targets and published our top 12 priorities across the themes for this financial year. This approach allows us to focus our efforts on the areas of greatest impact, while continuing to work internally on our additional targets.

Below you can find our public target relating to climate change.

We will monitor and analyse our carbon footprint data, identifying areas for greatest potential savings, prior to devising a strategy to set a longer term carbon reduction target for 2018/19

We measure our carbon footprint based on the UK Government’s Environmental Reporting Guidelines (2013) and emission factors from the 2016 Government 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 (click here to view Bellway’s library of reports) and through our participation in the Carbon Disclosure Project (CDP).
