* Article 12(1)(a) is amended to replace "controversial weapons" with "prohibited weapons."
* The definition of "prohibited weapons" is clarified to mean anti-personnel mines, cluster munitions, biological and chemical weapons prohibited by international arms conventions ratified by the majority of Member States.
* An annex is added, listing the specific treaties/conventions and the corresponding weapon types they prohibit:
* Convention on the Prohibition of Biological Weapons (1972).

COMMISSION DELEGATED REGULATION(EU) 2025/1775
of 28 August 2025
amending Delegated Regulation (EU) 2020/1818 as regards the definition of prohibited weapons
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EU) 2016/1011 of the European Parliament and of the Council of 8 June 2016 on indices
used as benchmarks in financial instruments and financial contracts or to measure the performance of investment funds
and amending Directives 2008/48/EC and 2014/17/EU and Regulation (EU) No 596/2014(1), and in particular
Article 19a(2) thereof,
Whereas:
(1) As indicated in the Joint White Paper European Defence – Readiness 2030(2), boosting public investment in defence
is indispensable, but it would not be sufficient. Undertakings established in the Union, including small and medium
enterprises and mid-caps should have better access to capital, including guarantee instruments for de-risking
investments, to bring their solutions to industrial scale and to drive the industrial ramp-up that the Union needs.
Although the financial sector shows a growing interest in defence, it, the defence sector remains an under-served
market due to limitations in investment policies of public and private financial institutions. The Joint White Paper
sets out a defence package providing financial levers to Member States to drive an investment surge in defence
capabilities. Making business easier and deepening the Single Market are among the package’s key goals. On 6 March
2025, the European Council called upon the Commission to swiftly take work forward on simplifying the legal and
administrative framework, for public procurement, industry cooperation, permitting and reporting requirements, to
address all obstacles and bottlenecks hindering a rapid ramping up of the defence industry, including for SMEs and
mid-caps.
(2) Commission Delegated Regulation (EU) 2020/1818(3) establishes climate-related labels for benchmarks which
require that all companies involved in any activities related to controversial weapons are excluded from EU Paris-
aligned and Climate Transition Benchmarks. However, the definition of controversial weapons in that Delegated
Regulation leaves too much uncertainty and confusion for administrators referred to in Regulation (EU) 2016/1011,
leading to confusion and should be clarified and simplified, notably because the relevant international treaties and
conventions to which Member States are parties do not reference controversial weapons but rather prohibited
weapons.
(3) It is therefore necessary to amend the definition of controversial weapons in Delegated Regulation (EU) 2020/1818
and replace it by a definition of ‘prohibited weapons’ to ensure legal certainty and consistency across the sustainable
finance rulebook and harmonised practices by benchmark administrators. This can be done while keeping a safe
level of exclusions in line with the objective of Regulation (EU) 2016/1011.
(4) Delegated Regulation (EU) 2020/1818 should therefore be amended accordingly.
(5) The implementation of this Regulation might lead to warranted effects on transactions by funds relying on those
indices based on EU Paris-aligned and Climate Transition Benchmarks. To avoid market disturbances, it is
appropriate to give existing benchmarks sufficient time to adapt to those changes,

(3) Commission Delegated Regulation (EU) 2020/1818 of 17 July 2020 supplementing Regulation (EU) 2016/1011 of the European
Parliament and of the Council as regards minimum standards for EU Climate Transition Benchmarks and EU Paris-aligned
