Real estate asset owners do not comply with the EU 2050 net zero target

The EU's 2050 net-zero target aims to reduce greenhouse gas emissions to zero, thus limiting global warming to 1.5°C.  Real estate asset owners have a fiduciary duty to address net zero, as this has direct implications for stranded asset risk, in addition to regulatory and political risk.  Failure to comply with the EU's 2050 net-zero target in real estate, both commercial and residential sectors could have the following negative consequences:


Due to increased carbon taxes, penalties, and compliance costs associated with carbon emissions. This will result in lower asset values.



Real estate asset owners who do not comply with the net zero target may face higher operating costs, such as increased energy bills and higher taxes on carbon emissions.


Real estate asset owners who are not compliant with the net zero target may face increased regulatory scrutiny.



Banks and other financial institutions may be hesitant to provide financing to real estate asset owners who do not comply with the EU's net zero target, as they may be viewed as a risky investment.


Limited access
to financing

Increased legal risks for real estate asset owners. The EU and individual member states are likely to introduce stricter regulations to achieve the net-zero target, including penalties and fines for non-compliance.



Real estate asset owners who do not comply with the EU's 2050 net-zero target could also suffer reputation damage, which could impact their ability to attract and retain tenants, customers, and investors.



Failing to comply with the net zero target could exacerbate the impacts of climate change. This could have significant negative consequences not only for real estate asset owners but for society as a whole.


Climate change

However, complying with the EU climate legislation can have positive impacts for real estate asset owners, including cost savings, increased property values, positive reputation, legal compliance, and futureproofing. It is therefore essential that real estate asset owners take action to reduce their carbon emissions and align with the EU and Irish climate legislation.

We need to move away from the taxonomy of denial and embrace the fact that climate change is a real treat to future generations, who are our sons, daughters, and grandchildren.
