For example, imagine a solar panel that costs $1000. They probably cost about $1000 to make, roughly. There may be some subsidy that allows them to sell at a loss but it’s safe to say it costs around $1000 to make, at a maximum.
You can also presume that energy is a factor in the cost to make a solar panel. So if 100% of the cost of the solar panel is energy, then some factory spent $1000 on energy to make that panel, max.
So that’s your hard limit on how much CO2 is being produced in the production of that solar panel: $1000 dollars’ worth.
