The need for national, ambitious narratives

• Nationalshortterm,climateeconomyfocussed(MACcurves)approaches
– Climateasaburden/riskoflockin?
• Nationalshortterm,«noregret»(stakeholdercompromise)policyapproaches

Providing appropriate finance solutions is key to harvest the macro economic effects
With short term, « consumption type » loans, energy savings will never pay back EE investment With long term, « real estate type » loans, up to 75% savings are economically viable
