Question

英语翻译
on the other hand,the scale of the reduction in greenhouse gas emmissions needed if atmospheric concentrations are to be limited to,say,450ppm co2e,is so great that(once sufficient international co-operation is in place) tax rates on fossil fules in particular may have to be much higher than at present,and thus generate significantly more tax revenues for at least the foreseeable future.
