Huang says that the consensus on the 2o-of-warming and 450-ppm limits makes the timetable for carbon reductions clear: the nations of the world will need to cut carbon emissions by a further 20-30 % over the eight years following the Kyoto Protocol's 2012 expiration.
黃正忠表示，全球各國在「極限」升溫 2 ℃、二氧化碳濃度控制在 450ppm 的共識下，減碳時程早已釐清：當「京都議定書」於 2012 年到期終止後，2013 ~ 2020 年全球仍須持續減碳 20 ~ 30 %。
