Grid Transmission & Distribution (T&D) Loss Factors by Country

Electricity transmission and distribution loss factors for 149 countries — the World Bank five-year-average T&D loss rate (percent of power output), plus the DEFRA/DESNZ 2026 ready-to-use UK T&D emission factors (kg CO₂e per kWh consumed) for grid electricity and district heat with their well-to-tank companions. 153 parameters for quantifying the Scope 3 Category 3 (fuel- and energy-related activities) emissions of transmission and distribution losses on purchased electricity.
