Holistic approach to decarbonization
If you want to secure and increase the value of real estate in the long term, there is no getting around CO₂ reduction and sustainable action. This is precisely where reliance comes in: with a holistic, digital process that enables the effective planning, implementation and management of ESG measures across entire portfolios. This is done in a practical and economically viable way - sustainability is no longer a "nice-to-have", but the key success factor for portfolio and asset managers.
Efficient decarbonization through bundled expertise
Allianz addresses key challenges in the area of ESG: a lack of data, unclear strategies and fragmented IT solutions. With a holistic decarbonization process, reliance offers a digital solution that covers all phases of the transformation - from portfolio planning to the implementation of measures at building level.
The close cooperation between the partners enables smooth implementation and comprehensive cost and project controlling throughout the entire decarbonization process. Real estate companies can optionally outsource the entire planning and implementation to the ESG Alliance - for a resource-saving and economical transformation.
