Key Messages from IPCC WGIII AR5
Working Group III contribution to the IPCC Fifth Assessment Report
GHG emissions growth has accelerated despite reduction efforts.
Working Group III contribution to the IPCC Fifth Assessment Report
But emissions growth has accelerated in the last decade – driven by CO2 from fossil fuel combustion

Working Group III contribution to the IPCC Fifth Assessment Report
There is far more carbon in the ground than emitted in any baseline scenario.

Based on SRREN Figure 1.7
Working Group III contribution to the IPCC Fifth Assessment Report
Climate change mitigation is possible –
and early action will make it easier
Working Group III contribution to the IPCC Fifth Assessment Report
Stabilising the atmosphere means moving away from business-as-usual – regardless of how ambitious we are.
6
40-70% reduction
Working Group III contribution to the IPCC Fifth Assessment Report
Delaying mitigation until 2030 increases the difficulty and narrows the options for limiting warming to 2°C.
7
Working Group III contribution to the IPCC Fifth Assessment Report
Ambitious mitigation involves transformation of the energy system.
Working Group III contribution to the IPCC Fifth Assessment Report

Emission patterns would need to change throughout the economy.

Working Group III contribution to the IPCC Fifth Assessment Report
Reducing energy demand is key - efficiency and behavioural change.

Reducing energy demand is key
Working Group III contribution to the IPCC Fifth Assessment Report
Decarbonization of energy supply would be needed

Decarbonization of energy supply would be needed.
Working Group III contribution to the IPCC Fifth Assessment Report
Mitigation comes at a cost, but strong economic growth can continue.
Working Group III contribution to the IPCC Fifth Assessment Report
Global costs rise with the ambition of the mitigation goal.
17
Working Group III contribution to the IPCC Fifth Assessment Report
Substantial reductions in emissions would require large changes in investment patterns.
18
Working Group III contribution to the IPCC Fifth Assessment Report
Climate change mitigation can bring co-benefits – health, energy security and other societal goals.
19
Based on Figures SPM.6 and 12.23
Working Group III contribution to the IPCC Fifth Assessment Report
Plans and strategies have expanded since 2007.
