As a number of scientific articles have shown, most recently by Kevin Anderson and Alice Bows in the Journal of the Royal Society, limiting the world to 2 °C warming most likely requires peaking total global carbon emissions in the next 5 - 10 years followed by immediate reductions to near - zero by 2050 (see Anderson and Bows emission trajectory options here, via David Roberts, and by David Hone here).
