Sentences with phrase «emissions decline between»
In all of the emission pathways considered, emissions peaked between 2010 and 2050 by construction, and thus cumulative emissions between 2010 and 2050 are reasonably well correlated to peak emissions rate, particularly when we only consider pathways with rates of emissions decline between 0 and 4 per cent.
