Measuring our emissions

Gas leakage contributes over 90% of NGN’s greenhouse gas (GHG) emissions as our gas is predominantly methane, a potent greenhouse gas. Through our continuous hard work, we are on track to achieve our target of reducing our Scope 1 (direct) and 2 (indirect - electricity) GHG emissions by 31% between our 2018 baseline and 2026, having already reduced by 26% by 2024.

We currently report Scope 3 emissions data from suppliers covering approximately 45% of our annual expenditure, and we remain committed to expanding this range over time. We have set reduction targets for a set of key Scope 3 emissions sources that we have consistently reported since 2018. These emissions have remained relatively stable between 2018 and 2024, largely due to our ongoing, long term gas mains replacement programme.
