  • The building sector is responsible for 28% of global greenhouse gas (GHG) emissions, two-thirds of which are indirect emissions (heating, lighting, ventilation, etc.).
  • Although not sufficiently exploited at the moment, it is crucial to carry out energy retrofitting in order to reduce indirect GHG emissions.
  • If energy retrofitting is so slow to be implemented and massively implemented, it is because it lacks both real public ownership and support from real estate.
  • We are on an encouraging trajectory, but it is not yet possible to meet the long-term objectives: energy retrofitting must therefore truly become a new social norm.
