Bio fuelst level
Bio fuel use for reduced emissions is difficult to justify depending on who you talk to.
During a recent conversation, with a senior executive of a very active world wide charity who regularly meet at senior goverment level, I was informed that the biggest CO2 emitters are the USA, China then forrest burning in Brazil and Peru combined. He stated that 35% of the worlds CO2 emmissions are from burning the rain forrests in Brazil and Peru which are being cleared mostly for grain and palm oil farming to make bio fuels!
I am sure there are other opinions available.
