Organic coffee shops and rooftop spinach farms will fill government coffers... we can be super low carbon, like Cuba. 
Australia and Germany have quietly abandoned job killing social experiments pushed under the guise of saving the world - they have found out what Ontario is slowly realizing as well - rushed "green" energy projects implemented using emotion and anecdote with a contempt for critical analysis have failed.

If the world was serious about emissions, air travel would be severely curtailed and population controls would be put in place immediately. 9 to 10 billion people by 2050? Super sustainable...
