The US has the biggest responsability on this planet, being the largest rich country, having emitted more than twice the CO2 per capita of Europe in the recent decades.
Can't expect pour countries to go quicker than the US.
You can replace say, gas powered heating with heat pumps and transfer the gas to storage for use in electric generators for when demand and supply diverge.
These transitions can be done in parallel but once you hit a certain degree of carbon free electricity it makes sense to redirect focus to shift towards electrification as things that may have been borderline become viable.
Besides that you could run smelting ovens, internal combustion engines, and other furnaces of hydrogen. Though that hydrogen will probably come from electricity if it isn't polluting.
