Persimmon’s total operational carbon footprint in 2016 was 32,599 tonnes CO2e. This was a slight increase on the previous year (2015: 31,557 tonnes CO2e) and was due to the increased number of homes built and the accompanying level of activity throughout the business. In fact, our carbon intensity – the volume of greenhouse gas emissions per home completed – declined slightly to 2.15 tonnes CO2e (2015: 2.17 tonnes of CO2e). This improvement was mainly attributable to the replacement of a large quantity of older telehandlers with more efficient models which reduced the volume of red diesel consumed on site.
Energy used to heat and light our regional offices, our development sites and power our Space4 factory increased by 9% to 33.4 million kWh in 2016 (2015: 30.7 million kWh). Of this, 33% was electricity and 67% was gas.
Our company car fleet decreased to 1,011 vehicles in 2016 (2015: 1,073). Overall since 2011, our fleet has grown by 37%. Despite this, fuel consumption has risen by only 29% to 3.1 million litres and carbon emissions increased by 31% to 8.1 thousand tonnes of CO2e over the same period.
This demonstrates the success of our approach, which has been to limit our staff fleet to more fuel efficient and lower emission cars. Average emissions of the company car fleet now stand at 101g/km (2015: 105 g/km) following further replacement of older cars with new, lower emission models. In addition, we have selected smaller, low emission vans as standard replacements for our previous larger, higher emission vehicles used by our maintenance fleet, and rolled out over 50 of these new vehicles during 2016. This saves fuel costs and helps reduce our emissions.
All data has been compiled in accordance with DEFRA Environmental Reporting Guidelines and emission factors from DEFRA’s Greenhouse Gas Conversion Factors Repository.
