When  Prime Minister Harper announced he will adopt an “intensity based” system for measuring greenhouse emissions, he was following the lead of President George W. Bush in using “greenhouse intensity” as a bogus way to measure carbon emissions.  The “intensity based” system would do nothing to cut emissions – only marginally slow their growth. Moreover, as a “voluntary” mechanism, they would attract few, if any, serious polluters. “Intensity based” is merely a new form of jargon for “business as usual” while the world burns.
