It depends on how much of the grid’s electricity is generated with fossil fuels I think. If the majority of the electricity is being generated with natural gas, a gas furnace can potentially use less gas to heat a home. But installing heat pumps also means that as more of the grid’s electricity comes from renewable sources, there will be an immediate drop in the amount of carbon released into the atmosphere to heat homes.
