‘000 tonnes of CO2 equivalent
Our overall business carbon footprint has fallen since the beginning of the RIIO-T1 period. This is mainly as a result of reducing emissions that result from energy losses from our transmission lines. The carbon intensity of our network has fallen due to increased renewable generation.
Actual leakage (kg)
Within our overall carbon footprint, we are measured against the amount of sulphur hexafluoride (SF6) that leaks from our assets. This is a gas with excellent insulating properties, but which is much more damaging to the environment than CO2. Our leakage levels have been less than our target for each year under our current business plans.
Our environmental performance annual statement
The Environmental Discretionary Reward incentivises our Electricity Transmission business to provide evidence on how we are achieving high standards in environmental management, as well as facilitating the industry towards a low carbon energy system. To support this incentive, we produce an annual statement, which you can download.
We hope you find the statement an informative read. We want to know what you found most useful and where you’d like more in-depth information. We also welcome your feedback on how we’re doing, so either email us or take part in our online survey.
