I think it's called carbon off setting.... Sell 20,000 solar panels and you can pretty much burn what you like, rain forests, polar bears, dolphins, White tigers, anything really
Me and my mate came up with this theory whilst doing €2k of fuel in his 56' Princess going from Palma to Ibiza.... God bless the tree huggers!!
