Canada · Carbon Intensity of Electricity (Monthly)

## What this measures

The greenhouse gases emitted for each kilowatt-hour of electricity generated in Canada, in grams of CO2-equivalent per kWh, one value per month, dated the first of the month. Ember divides power-sector emissions by total generation, using life-cycle emission factors for each fuel.

## Why it matters

It is the single number for how clean a grid is. It decides how much an electric car, a heat pump or a data centre actually emits where it is plugged in.

## How to read it

Lower is cleaner. Coal-heavy grids run highest; grids built on hydro and nuclear run lowest. Monthly values swing with the seasons (hydro and solar output, heating demand).

## What it does not say

It covers generation in the place, not the electricity it imports. Life-cycle factors mean even wind and solar carry a small value.
