BUILDINGS IN A LOW-CARBON WORLD
COP 21
Research & Capacity Building in Energy Efficiency and Green Buildings Side Event
Paris, 3 December 2015
John Dulac
Lead Buildings Analyst, Energy Technology and Policy Division
International Energy Agency
To shift the energy sector onto a low-carbon path that supports economic growth and energy access:
1. Take five key actions, led by energy efficiency and renewables, to peak then reduce global energy emissions.
2. Use the Paris Agreement to drive short-term actions consistent with long-term emission goals.
3. Accelerate energy technology innovation to make decarbonisation easier and even more affordable.
4. Enhance energy security by making the energy sector more resilient to climate change impacts.

Buildings and Global CO2 Emissions
Buildings are responsible for ~30% of global energy
related CO2 emissions.

Buildings energy consumption increased by 33% since 1990.
It could increase by another 50% to 2050 without action.
