2. Working Group III contribution to the
IPCC Fifth Assessment Report
GHG emissions growth has accelerated
despite reduction efforts.

3. Working Group III contribution to the
IPCC Fifth Assessment Report
Plans and strategies have expanded since 2007.

4. Working Group III contribution to the

But emissions growth has accelerated in the last decade –
driven by CO2 from fossil fuel combustion

There is far more carbon in the ground than emitted in any
baseline scenario.

GHG emissions rise with income and population -
but are moderated by energy efficiency

GHG emissions rise with income and population -
but long-term energy decarbonisation has been reversed.

8. Working Group III contribution to the
IPCC Fifth Assessment Report
Climate change mitigation is possible –
and early action will make it easier

9. 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.

40-70% reduction

Delaying mitigation until 2030 increases the difficulty and
narrows the options for limiting warming to 2°C.

Ambitious mitigation involves
transformation of the energy system.

Emission patterns would need to change
throughout the economy.

Emission patterns would need to change

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

21. Working Group III contribution to the

Decarbonization of energy supply would be needed.

Decarbonization of energy supply would be needed.

24. Working Group III contribution to the
IPCC Fifth Assessment Report
Mitigation comes at a cost,
but strong economic growth can continue.

25. Working Group III contribution to the
IPCC Fifth Assessment Report
Global costs rise with the ambition of the mitigation goal.

26. Working Group III contribution to the
IPCC Fifth Assessment Report
Substantial reductions in emissions would require large
changes in investment patterns.

Based on Figures SPM.6 and 12.23
Climate change mitigation can bring co-benefits – health, energy
security and other societal goals.
