> Almost all emissions come from factories.

industry, transport and home use (heating & A/C mostly) are all roughly 30% of emissions.

(another way of splitting it says electricity, industry, heating, and transport are roughly almost 25% each. It depends whether you count electricity on its own or bundle it with how its used)

But I agree with you about solutions. The market will quickly bankrupt any companies that induce extra costs to decarbonify. It's the governments job to ensure that externalized costs like CO2 emissions are internalized via carbon taxes. (or alternatives to carbon taxes, which are worse)
