Isn't something like half of emissions from construction (steel and cement) and agriculture? Limiting fossil fuels is a good idea, but as that declines the significance of other sources of CO2 will increase. And those two sources are already increasing in absolute terms as well and will continue to increase as long as global population and living standards do as well.
