You do have a point.
How many of us would volunteer to cut back on our power consumption dramatically?
How many folk would give up their car and catch public transport?
How many people would avoid purchasing plastic and metal products, both plastic and metal products involve high CO2 emissions to manufacture?
How many countries around the world would drastically reduce coal and petroleum consumption for energy generation. Energy that is used for manufacturing, cooling, heating, e.t.c?
Care to limit your demand for agriculture products?
I seriously doubt whether many people in any society would understand the ramifications, of attempting to reduce their CO2 emissions.
