Sustainability at LEG

Working together for greater emissions efficiency in the building sector

At LEG, we have always been committed to forward-looking, sustainable solutions in climate protection. The latest findings of the @Gesamtverband der deutschen Wohnungswirtschaft (GdW - German Housing Industry Association) and leading scientists clearly show that despite the industry's total investment of EUR 545 billion in the energy-efficient refurbishment of buildings between 2010 and 2022, space heating consumption per square meter in private households remained virtually unchanged. This shows that focusing on energy efficiency alone is not enough.

We therefore support the @Initiative Praxispfad, which is calling for a decisive paradigm shift: Instead of just focusing on energy efficiency, we should focus more on CO2 reduction and therefore emissions efficiency. 


Our ESG goals

Our sustainability strategy will therefore focus on achieving climate targets and decarbonization in the future. Our guidelines are emissions and cost efficiency as well as the business orientation “Sustainability as business opportunity”. We have set ourselves further long-term goals in the social sphere.


Our decarbonization pathway

We have set ourselves ambitious climate targets for 2030: Starting from 2019, a total of 47% of Scope 1 and 2 emissions are to be reduced. The international Science Based Target Initiative last validated our CO2 reduction pathway in December 2024. LEG is aiming for a target of around 21 kg CO2e/m² in the 2030 pathway. By 2045, we want to be almost greenhouse gas neutral and would then be at 0 to 5 kg CO2e/m². The decarbonization pathway includes all of the company's emissions, from the portfolio to common areas, administration and emissions from the biomass cogeneration plant. For the climate adjustment, we used the DWD climate factors (average year to be expected for Germany on a long-term average according to the German Weather Service). With our decarbonization pathway, we are well on the way to achieving our climate targets in 2024.


Our measures

Emission efficiency will play a much more important role in the future. After all, COreduction must be the top priority for climate protection. 


Our holistic climate protection strategy: three main clusters

Within our sustainability strategy, we divide our energy-saving options into three clusters: with the help of emission-efficient heat supply, such as replacing the heating system or installing air-to-air heat pumps, we will contribute around 50 to 55% to the overall CO2 reduction by 2030, while energy demand-reducing measures with smart, AI-controlled thermostats will contribute a further 30 to 35% and energy modernization measures an additional 10 to 15%.


Our Green Ventures

We offer solutions! In our climate protection measures, we have always paid attention to saving as many CO2 emissions as possible with every euro invested and rely on innovative green solutions: our green ventures dekarbo°, termios and RENOWATE.
