You have to realize that voluntary reduction of CO2 will never happen in amounts large enough to do anything other than slightly postpone the inevitable. It's the equivalent of buying a drunk a bottle so he doesn't detox today, but tomorrow.
OTOH, MANDATED reduction of CO2 violates the rights of man so severely that, frankly, the cure would be worse than the disease: far better to live as a man, in a somewhat hotter, drier world, than to live as a mouse, and say "Mother May I?" every time you want to turn up the thermostat.
And besides, "polluting less" is the stupid way to deal with ecological pressures; the SMART way is to use our superior brains to engineer our way out of the mess we're in! (Example: when London suffered Cholera outbreaks and a Thames so stinky that it was impossible to hold Parliament on windless days...did everybody "endeavor to poop less?" Of course not! Sir Bazalgette engineered a sanitary sewer that solved the problem.)
Thinking that the solution to GW is "everybody, burn less stuff!" is akin to thinking London's solution was: "Everybody, poop less!"
