The graph above identifies the low-carbon industry segments that need to grow to avoid tipping points and models their individual contributions. The upward limit of average, global growth rates for the various industry segments is 30%; on that basis we have to see all (not just a few) low carbon industry segments growing at maximum rates by about 2014 to avoid 2 degrees. The sooner rapid growth starts the shallower the trajectory needs to be. The diagram is from the WWF Climate Solutions II report.
