Greenhouse gas intensity limits

What you need to know

Owners and managers of existing large office and retail buildings will be subject to: 

  • Greenhouse gas intensity (GHGi) limits starting in 2026  
  • Heat energy intensity limits (HEL) for natural gas and district energy use starting in 2040 


GHGi calculations

Our GHGi calculations do not consider a building’s electricity use because BC’s electric grid is supplied by hydro-electricity that produces very low amounts of carbon emissions. 

Greenhouse gas intensity (GHGi) is an industry-standard measurement that reflects the quantity of greenhouse gas emissions (kilograms of carbon-dioxide-equivalent) a building produces each year for every square metre of conditioned floor space.

Future greenhouse gas and heat energy intensity limits

Initially, our GHGi limits will only impact Vancouver’s largest office and retail buildings.

What you will be required to report in 2027

Starting January 2027, building owners and managers subject to the 2026 GHGi requirement will have until:

  • June 1, 2027, to submit a complete energy and carbon report
  • August 1, 2027, to get a carbon emissions operating permit (CEOP)
