carbon credits

WOULD SOME ONE BE ABLE TO INFORM ME OF THE VALUE OF CARBON CREDIT WITH A COMPANY LIKE EHR . IF THIS COMPANY IS ABOUT TO START PRODUCING POWER SURLEY THIS IS AN ADDED ADVANTAGE. AS LARGE COMPANIES ALL OVER THE PLACE WOULD BE BIDDING FOR THESE . SMALL COMPANIES LIKE EHR WOULD THEN BECOME A USEFUL ASSET FOR THESE COMPANIES REQUIRING CREDITS TO OFF SET THEIR POLLUTION.
IF ANY ONE COULD GIVE ME SOME INFORMATION ON THIS IT WOULD BE MUCH APPRECIATED. I WOULD THINK IF THE CREDITS FOR CARBON WERE TRADABLE THIS SURELY WOULD MAKE THIS COMPANY A VERY CHEAP OPTION AND A VERY CHEAP WAY OF GAINING A AN ON GOING CARBON CREDIT. THANKS
