ITR Global Tax 50 2022: Aoife O’Leary

CEO, Opportunity Green

Aoife O'Leary_OpportunityGreen.jpg

Aoife O’Leary, CEO of environmental consultancy Opportunity Green, may seem an unlikely addition to the Tax 50, but she has earned her place in this year’s list due to her work on carbon taxation in the shipping industry.

As a lawyer and an economist, O’Leary brings impressive expertise to the discussion whether she is working with businesses, governments, international organisations or NGOs. She has become a prominent voice in the media on carbon tax advocacy in maritime sectors.

Opportunity Green works closely with the UN’s International Maritime Organization (IMO) to try to find a path towards decarbonisation of the shipping industry. Her team works with governments of small island nations and developing countries to help meet the IMO’s climate objectives.

Breaking down the entire 50 individually according to the impact they made would require too granular an approach. Each entry is in alphabetical order as part of categories, i.e. individuals, to make it simpler to navigate.
