1. Every credible analysis finds that renewables and energy efficiency will provide only a portion of the emissions reductions needed if we are to "decarbonize" our economy.

2. The decarbonized solvent is suitable to decarbonize flue gas of coal-fired power plant smoke, industrial kiln gas, and the like.

3. Special solvents can be used to decarbonize and desulfurize waste catalysts to replace the high-temperature roasting pretreatment process.

4. We'd have to keep geoengineering indefinitely to balance out continued greenhouse-gas emissions, and the motivation to decarbonize might disappear if we believed we had an insurance policy.

5. Global greenhouse gas emissions have skyrocketed over the past few decades on the back of relatively cheap oil, but as the price rises, it pays to decarbonize, and the climate will benefit.

6. Moreover, agreement must be reached before 2008 and should include additional support to decarbonize "developing" countries, funded in part by penalties for non-compliance of "developed" countries.

7. Hybrid cars, wind turbines, algae biofuel — businesses and policymakers alike are searching for the technological fixes that will decarbonize our lives.
