Invest that money into eco-friendly companies? Or donate it to eco-friendly causes.
And a lot of "eco-friendly" consumption is pure green-washing. I know people that provide eco friendly services, and I know what they spend their money on, and it is mostly just normal consumer consumption (e.g. international holidays which is clearly pure "waste"). Or eco-friendly people with 5 kids - who just can't see that children are a multiplier effect on current and future consumption.
I'm thinking supporting tree-planting NGOs might be a good start for example. This goes directly towards carbon-sequestration.
