As much as we would like to believe otherwise, the fact is that carbon emissions won’t be lowered by a deal. If that were politically possible, it would have been done a long time ago – if not at the 1992 “Earth Summit” in Rio de Janeiro, then in Kyoto 12 years later; and if not in Kyoto, then in Copenhagen last December.
“地球一小时”的致命伤恰恰就在这里。尽管我们不愿承认，可事实是，任何国际协定都无法实现减排。如果那种办法在政治上行得通，好久以前早就应该搞定了，先是1992年里约热内卢的“地球峰会”，到12年后的京都，再到去年12月的哥本哈根。可实际上根本搞不定。
