On 26 March, upon invitation of its members, Luxembourg officially joined the Equal Rights Coalition (ERC) alongside Cabo Verde, Denmark and Iceland. Ambassador Sylvie Lucas signed the Founding Principles of the Coalition on behalf of Luxembourg.

The intergovernmental Equal Rights Coalition is dedicated to the protection of the rights of LGBTI people. It was launched in July 2016, under the leadership of Uruguay and the Netherlands at the Global LGBTI Human Rights Conference in Montevideo. The ERC advances the human rights of LGBTI persons and promotes inclusive development in both member and non-member countries. With 39 member states, the ERC advances its agenda by engaging with civil society organizations and multilateral agencies.

Luxembourg has an active policy of promoting LGBTI rights globally, through foreign policy and development policy instruments, as well as in multilateral organizations, while, at the same time, the Luxembourg government continues to work to guarantee equal rights for LGBTI people at the domestic level.
