Do you consider methane leaks as a 10 year investment plan? There is no tracing where the co2 came from once ch4 turns into co2 (we've had methane leaks for decades). :)

The opportunities for fraud have already been proven.
There is no money (gdp) in preventing methane leaks and we get the upside of higher temperatures and carbon credit manipulation.
Carbon credits schemes profit from neglect. The "save the world types" just chased co2......
