Cement is an interesting case, by the way, because it's almost impossible to clean up the industry. You could run the plant with solar power and you'd still produce a lot of CO2, because its release is inherent in the chemical reaction that makes cement. Cement companies are sensitive to this problem, and are slowly developing technology for carbon capture. It's a long road ahead for them.

Nearly all the countries of 15. _ along with Australia, committed themselves to binding reductions. The U.S. stood alone as declining to ratify, although it was soon followed by 16. , which renounced its participation. Many countries signed the treaty but escaped binding targets because they were poor, with very large populations, and because reducing their emissions would have slowed economic growth. The three giants in this situation were 17. C and 18. I , and Brazil.
