16. Conclusions
Current emission reduction proposals and
nationally implemented policies for 2020 are not
yet sufficient for a 2°C pathway
First INDCs are being announced
Preparation of INDCs:
Stakeholder process
More than one target
Explanation why this is a fair and ambitious
contribution

18. Experience from the past on
mitigation commitments
Diverse: Pledges are very diverse (economy wide targets to individual projects)
Ambiguous: Pledges often were ambiguous and had to be clarified
2°C: Some pledges are influenced ranges needed for 2°C
Japan -25%, Norway -40%, Mexico and South Korea 30% below BAU…
National: Some pledges are also primarily driven by national discussions
EU, USA, …
Unchangeable: Pledges once made did not change
No major economy has changed its pledge of 2009, although the gap is widely accepted
Even countries that will over-achieve their pledge (new circumstances or more information) do not
change it

19. What types of pledges were
presented?
Type Examples Characteristics
Economy wide
emission
reduction targets
To base year: USA, EU, Japan Full flexibility where to reduce emissions
To BAU: Brazil, Mexico, Chile,
South Korea
Full flexibility where to reduce emissions
Can factor in economic growth
Creates a “moving target” if baseline
changes
To GDP: China, India Full flexibility where to reduce emissions
Adaptive to changes in economic
development
Emission outcome uncertain
Energy targets China, Peru Closer to actual actions than emission
targets
Policies Brazil, Argentina Directly under control of the government
Projects Ethiopia Very detailed in scope

21. Comparison to BAU
BAU is counterfactual
BAU includes many different developments
Example Brazil
36.1% to 38.9%
below BAU in 2020
www.newclimate.org 21
22. Comparison to effort sharing
Large range of effort sharing approaches, e.g. per capita, carbon
budgets, equal costs, …

23. Comparison to potential
Large uncertainties

Assumptions on cost
elements?

25. Comparison to low carbon
policy package
Possible approach
1. Choose area of
intervention
2. Identify BP
incentives and
barriers
3. Develop
benchmarks
4. Rate policy against
benchmark
www.newclimate.org 25
26. Policy package (2) – example building
sector- energy efficiency
Indicator for incentives Benchmark for evaluating against best
practice
• Incentive (regulation, support and
information) for use of efficient appliances,
including air conditioning
4: 2-3% per year
0: No incentive
Method: fraction of appliance covered and stringency of
the standards (Japanese Top runner or ecodesign
directive). If air conditioning is a major consumer, then
buidling standards need to be considered)
• Efficiency standards for new buildings for all
types of buildings
4: Zero emissions buildings by 2014
2: Zero emissions buildings by 2020
0: No trajectory to zero energy buildings
• Incentive for high retrofit rates for all types of
existing buildings (for complete retrofit, i.e. full
building envelope & upgrade supply system)
4: > 3% per year (average 2010-2020) and >2% afterwards
0: < 1 % per year
• Policy for efficiency improvement for other
than heating fuel uses (cooking, hot water
use)
4: > 3% per year (average 2010-2020) and >2% afterwards
0: < 1 % per year
• Level of energy and/or CO2 taxes (applicable
to electricity fuel consumption in buildings)
4: tax is > 100% of energy price
0: no tax

30. Ways to assess contributions
Comparison Considerations
To BAU • BAU is counterfactual
To effort sharing • Wide rage of possible outcomes
To mitigation potential • Costs compared to a BAU, which is
counterfactual
Of decarbonisation indicators • Forward looking, no BAU necessary
• Indicators close to actions, specially on sectoral
level
To good practice policy package

• Forward looking, no BAU necessary
