With 80% of the EU's residential properties built before 2000, real estate companies could face massive investments in their quest to cut emissions after 2030. Rated real estate companies in Europe are targeting a 40%-50% reduction of emissions by 2030. This represents a 15%-20% energy efficiency improvement, which is in line with updated regulatory requirements. Decarbonization solutions are already generally available, but companies will need to continue to renovate their portfolios to meet regulations and their own goals.
