FIGURE Syn.4 Because emissions of carbon dioxide are greater than the sinks that remove it, emissions reductions larger than about 80% (green line-top graph) are required if concentrations are to be stabilized (green line-bottom graph). The lower graph shows how carbon dioxide concentrations would be expected to evolve depending upon emissions for one illustrative case, but this applies for any chosen target.
