A mortgage portfolio standard is a mechanism that gives mortgage lenders an incentive to do two things: set a path to raise the median energy performance of the buildings their mortgages cover, towards 2030 and 2050, and encourage clients to improve their property. It relies on the EU Taxonomy criteria in Article 3 of Regulation (EU) 2020/852 for what counts as environmentally sustainable. The definition describes a mechanism; it does not impose one. In the operative articles the term appears once, in Article 17(7), in a list of funding and financial tools that Member States must promote to mobilise investment, alongside energy efficiency loans and mortgages, energy performance contracting and pay-as-you-save schemes. Article 17(11) goes further on lending products: Member States must adopt measures that promote energy efficiency lending such as green mortgages and green loans, and make sure banks and other financial institutions receive information on financing opportunities. So a bank is not, under EPBD IV itself, required to adopt a portfolio path. Whether a lender faces one depends on what its Member State builds on Article 17(7), and on separate rules on prudential and sustainability disclosure that this entry does not cover. The median, not the average, is what the definition targets, which keeps a few very efficient buildings from masking the rest of the book. > **What we could not establish** > > The definition relies on Taxonomy criteria that are themselves set in delegated acts, so the threshold for a sustainable building loan can move without EPBD IV changing. This entry fixes the term. It does not decide whether the term catches your institution; counsel decides that. ## Questions and answers ### Do mortgage portfolio standards oblige banks to improve their portfolio? Not under EPBD IV alone. The Directive defines the mechanism and, in Article 17(7), requires Member States to promote it among other financial tools. A duty on a lender would come from national measures. ### Why does the definition refer to the EU Taxonomy? It relies on Article 3 of Regulation (EU) 2020/852 for the criteria that make an economic activity environmentally sustainable: substantial contribution, no significant harm, minimum safeguards and technical screening criteria. ## Sources - [Directive (EU) 2024/1275 on the energy performance of buildings (recast)](https://eur-lex.europa.eu/eli/dir/2024/1275/oj/eng) (EUR-Lex · 8 May 2024) - [Regulation (EU) 2020/852 on the establishment of a framework to facilitate sustainable investment](https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX:32020R0852) (EUR-Lex · 22 June 2020) ## Related content ### Regulation - [Energy Performance of Buildings Directive (EPBD IV)](https://gencompl.ai/regulations/epbd): EPBD IV is Directive (EU) 2024/1275, the recast Energy Performance of Buildings Directive.
