The real estate sector must commit itself to the challenges of climate change like all other economic sectors. The industry is responsible for a significant percentage of its carbon footprint and is therefore obliged to reduce this impact. This requires significant economic resources from multiple sources of capital and financing. Likewise, its impact on the use of raw materials makes it necessary to boost investment in the development of new materials and production processes. The reduction of the carbon footprint and its value linked to the emission rights market represent an opportunity both to reduce this impact and to operate with these rights. Commitment and performance will be discussed in this session.
