Our Mandate

The International Tax Task Force has received the highest possible level of endorsement from the founding countries. Its mandate builds on the Outcome of the Global Stocktake and complements other initiatives including the call for a UN Tax Convention and the OECD’s two-pillar global tax reform.

Who we are

The task force is led by co-chairs France, Barbados and Kenya. Other member states include Antigua & Barbuda, Spain, Marshall Islands and Colombia, with the European Commission, IMF and United Nations observing.

Each country co-chair has appointed a special Sherpa to the task force:

Climate Change Envoy, Kenya
Ali Mohamed
Director General for Globalization at the Ministry for European and Foreign Affairs, France
Aurelien Lechevallier
Principal Technical Advisor, Barbados
Dr. Arnold McIntyre

The task force’s secretariat is hosted by the European Climate Foundation (ECF), and is co-led by ECF Chief Executive Laurence Tubiana.
