But they're not just buying the juice they're also buying the carbon in the trees to offset the shipment costs associated with carbon to get the product into Europe.

So whenever I fill up my gas, I think of that liter, and how much carbon.

Environmental concerns should also be addressed, especially by the developed countries that are responsible for most carbon emissions.

So empowering China to deal with its own problems of carbon is good for everybody, and it's not a zero sum, I win, you lose.

Carpooling is seen as a more environmentally friendly and sustainable way to travel as sharing journeys reduces carbon emissions, traffic congestion on the roads, and the need for parking spaces.

If China develops greater energy security and greater capacity to deal with its problems of carbon emissions, that's good for us as well as good for China as well as good for everybody else.

And another idea that I had as well, that was brought forward by an ecologist he basically did a calculation where he took one liter of gas and said, well, how much carbon it would take, and how much organic material?
