The biggest environmental risk comes from complacency 20 or 30 years from now. So we need to set up systems that are self funding. i.e. a portion of the oil revenue must be directly directly to the government departments that enforce the rules. But it can't be user-pay because that creates conflicts of interest.
OK but lets set this up before the pipelines are built because if it isn't, it never will be. The attitude here seems to be, build the thing and we'll deal with all that inconvenient stuff later. Ya right.
