++++++++++++++ ++++++++++++++ Beyond Kyoto A Long-Term Target: Framing the Climate Effort Prepared for the Pew Center on Global Climate Change by Jonathan Pershing (World Resources Institute; formerly International Energy Agency) Fernando Tudela (El Colegio de México)
2
++++++++++++++ ++++++++++++++ Climate Change: a long-term challenge Impacts: huge time lags (over a century) Mitigation: long life cycles Political systems: ill- prepared to cope with long-term problems Societies heavily discount distant impacts: Time line
3
++++++++++++++ ++++++++++++++ Long-term targets Article 2 UNFCCC: stabilize concentrations to avoid dangerous interference…+ qualifier.. UNFCCC + KP: emphasis on short-term action Climate regime needs bolstering Could negotiating a long-term target be useful / essential to boost / guide action?
4
++++++++++++++ ++++++++++++++ The case for long-term targets Defining a goal for climate efforts Awareness of long-term consequences Calibrating progress: Are we on track? Enhancing economic certainty: stable signals for technological change Limiting future risks Mobilizing society Promoting global participation Some Parties are already adopting non-binding long-term targets: EU, UK, Sweden
5
++++++++++++++ ++++++++++++++ The Climate Cycle
6
++++++++++++++ ++++++++++++++ Setting targets at different stages A target set at any stage has effects on all other stages; target setting involves the whole cycle Entry point would frame the process –Early : strongest policy control, short time lags –Later : higher legitimacy (specific risks avoided), but: huge time lags + accumulated uncertainties The paper addresses target setting at every stage: –Possible form of the target –Implications for other stages –Pros & cons –Negotiating hurdles
7
++++++++++++++ ++++++++++++++ The Climate Cycle: Activity Target
8
++++++++++++++ ++++++++++++++ EXAMPLE: Technology Options Hydrogen Renewables Capture and storage
9
++++++++++++++ ++++++++++++++ The Climate Cycle: Emissions Target
10
++++++++++++++ ++++++++++++++ Energy-Related CO 2 Emissions World emissions increase by 1.8 % per year to 38 billion tonnes in 2030 – 70% above 2000 levels 0 5,000 10,000 15,000 20,000 25,000 30,000 35,000 40,000 1970198019902000201020202030 million tonnes of CO2 WorldOECDTransition economiesDeveloping countries (Source: IEA WEO, 2002)
11
++++++++++++++ ++++++++++++++ The Climate Cycle: Concentration Target
12
++++++++++++++ ++++++++++++++ Concentration of CO 2 Equivalent (ppmv) Source: IPCC TAR
13
++++++++++++++ ++++++++++++++ The Climate Cycle: Temperature Target
14
++++++++++++++ ++++++++++++++ Temperature Change
15
++++++++++++++ ++++++++++++++ The Climate Cycle: Impacts Target
16
++++++++++++++ ++++++++++++++ EXAMPLE: Crop Yield Change Percentage change in average crop yields for the climate change scenario. Effects of CO 2 are taken into account. Crops modeled are: wheat, maize and rice. Source: IPCC TAR
17
++++++++++++++ ++++++++++++++ The Climate Cycle: Backcasting
18
++++++++++++++ ++++++++++++++ CO 2, temperature, impacts, emissions, and cost
19
++++++++++++++ ++++++++++++++ Setting a long-term target: the obstacles Technical difficulties: uncertainties Political obstacles: –Global burden defined burden sharing –defining “acceptable risk” compensations –Equity issues become central –Dilemma: negotiation´s success vs stringency of outcome –Limited “negotiating energy”; morale hurt by failure
20
++++++++++++++ ++++++++++++++ Conclusions Negotiating a long-term target: liabilities outweigh potential benefits If undertaken at all, the negotiation should focus on the earliest stages of the cycle: activities, emissions [input rather than output] Alternatives to a long-term target: Hedging: a medium-term target that would leave some long-term concentration target open Targets with limited constituency (but including leading players) Notional target, informal adoption Directional goad based on strengthened science
21
++++++++++++++ ++++++++++++++ A Hedging Strategy Source: IPCC
22
++++++++++++++ ++++++++++++++ Conclusions II More important than any tool, including target- setting, is willingness to act The value of developing a long-term target will depend on whether or not the negotiating process fosters political will
