Grid electricity CO2 by region API

Convert electricity use (kWh) to CO2e using region/source grid-intensity factors (kg CO2/kWh): global 0.475, US 0.386, EU 0.231, UK 0.193, China 0.555, India 0.708, France 0.056, Norway 0.026, plus per-source coal 0.95, gas 0.41, nuclear 0.012, solar 0.041, wind 0.011. Returns the factor used, total grams/kg/tonnes CO2e and tree equivalents. Answers 'CO2 of 1000 kWh in the US','emissions on the French grid','coal vs wind per kWh','grid carbon intensity by country'.
