Why electricity & gas supply emissions data matters
Every company's Scope 2 depends on the electricity it buys, so the emissions intensity of power suppliers flows through to their customers' reports. Because generation portfolios differ, emissions intensity and the direction of travel year on year say more than absolute totals.
