Furnace Carbon Emissions
A 95% AFUE gas furnace burning 75-110 GJ/year produces approximately 3.5-5.5 tonnes of CO2 per year. This includes both the direct combustion emissions and the upstream emissions from natural gas extraction and transportation. The carbon tax adds $350-550/year to the gas bill, reflecting the environmental cost.
Heat Pump Carbon Emissions
A heat pump operating in BC produces approximately 0.1-0.5 tonnes of CO2 per year — 90% less than a gas furnace. BC electricity is 95%+ renewable from hydroelectric sources. The small emissions are from the small amount of natural gas used in BC electricity generation during peak demand.
Environmental Decision
Switching from a gas furnace to a heat pump in BC reduces your home heating carbon footprint by 90%. This is the single most impactful change a Vancouver homeowner can make for the environment. Combined with CleanBC rebates ($2,000-6,000), the switch is increasingly affordable. Many Vancouver homeowners choose a heat pump primarily for environmental reasons.
