One thing not mentioned is a lot of high quality indoor grows will actually supplement CO2 into the air from tanks, or less frequently, natural gas burners. (Burners aren't ideal, since they generate heat, which is the major problem in indoor gardens).<p>It's not just the CO2 from the energy (although, that's probably the majority, depending on the source of the power grid).
Is this a fair comparison?<p>Typically emissions are grouped in three scopes.<p>- scope 1: direct emissions<p>- scope 2: emissions generated by suppliers<p>- scope 3: emissions that come from using the product.<p>Cannabis plantations consume a lot of electricity and will mainly result in Scope 2 emissions.<p>Coal mining will mainly result in Scope 3 emissions. This is a customer burning the goal.<p>More accurate title would be.<p>Colorodas legal cannabis farms have greater scope 1 + 2 emissions as coal mining.
