Our Carbon Calculations
Our approach to reducing carbon is led by the Board of Directors. Paul Bentley sits on the Infrastructure Working Group, a delegation of the Green Construction Board which was established as consultative forum for government and UK industry.
JN Bentley has signed up to the Infrastructure Carbon Review – a joint initiative to reduce carbon in infrastructure – and now has representation on a panel shaping a new Publicly Available Standard (PAS) for carbon measurement and management.
Our energy and carbon monitoring is now into its eighth year, during which time the scale and nature of the company’s operations has changed significantly. Despite this, over this eight year period there has been a significant overall decrease in operational carbon emitted from an initial 177 tonne CO2e per £1 million turnover in 2008, down to 132 tonne CO2e per £1 million turnover in 2015.
The decrease in energy-related carbon (i.e. gas, electric and fuel) has been relatively linear over recent years showing physical and behavioural efficiencies in plant, vehicles and buildings, whereas the CO2e associated with embodied carbon has been slightly more sporadic and work-type dependant and has been significantly influenced by AMP cycles in the water sector.
In 2015 embodied carbon increased significantly as a result of several large schemes that utilised pre-cast concrete. While this, to a certain extent, is out of our control, the use of pre-cast as best practice technology affords carbon savings compared to traditional methods.
Going forward, as the order books continue to grow, we will continue to invest in the most efficient plant, seek to pioneer new innovative design with lower OPEX costs, and continue to raise awareness through training to ensure we continue to reduce operational and embodied carbon associated with our work and its legacy of operation.
