RE:give your head a shake trudeau !!The world continues to burn more coal. The dirtiest of all fossil fuels. Coal now accounts for a third of all engery produced in the world. Canda has reduced is use of Coal and continues to do so. Until the rest of the world reduces the use of coal , why should we even consider an emission cap. Build another pipeline or two and export the more cleaner fossil fuels, oil and natural gas to the rest of the world and that would help reduce emission faster than the proposed liberal bullshat.
