According to the Commission LTS, the EU must halve its energy consumption by 2050. Energy efficiency therefore must play a central role in achieving net-zero GHG emissions by 2050.
Considering that the world economy will triple by 2050 and that global population will increase by nearly 2.3 billion by 2050, energy efficiency is the most cost-effective way to decouple economic growth from emissions.
Significant reductions in overall energy demand will come from energy use in buildings. Residential and commercial buildings currently account for 40 % of EU energy consumption – with 75 % of these buildings being built before energy performance standards existed – 36% of emissions and 50% of the total mineral resources extracted from the planet. Most of the housing stock of 2050 already exists and will need to be renovated. Our building stock needs to become net zero carbon, which involves ramping up the rate and depth of renovation and ensuring efficient and decarbonised energy supply in the building sector. The “Renovation Wave” needs to build from the implementation of the Long Term Renovation Strategies, but also explore new drivers and triggers, including regulation, in order to scale up what has worked well in some countries.
