The Conference in Paris

Climate & Biodiversity: Tackling global footprints

Dear GCET friends,

It is a great pleasure to invite you to Paris-Dauphine University for the 24th Global Conference on Environmental Taxation. GCET is the leading global forum for exchanges on the principles and practices of environmental taxation and other market-based instruments designed to protect the environment and foster sustainability. In line with the tradition, a selection of the best contributions will also be published this year in the prestigious “Critical issues in environmental taxation” from Edward Elgar publishers.

The scientific program for GCET24 will cover issues relating to environmental taxation and focus on economic tools to tackle mitigation issues, biodiversity losses and climate vulnerability, including but not limited to:

  • Challenges of agriculture and forestry for carbon sequestration, non-CO2 GHG & biodiversity,

  • Challenges of urban areas for land use, CO2 emissions and climate-resilience,

  • Supranational regulations to tackle domestic and imported CO2 emissions and biodiversity losses with a special focus on the recent reform of EU-ETS,

  • Business and biodiversity : Economical and financial risks and opportunities associated with the decline of biodiversity, nature-based solutions.


We look forward to welcoming you in Paris for this new edition of the conference.

Christian de Perthuis & Edouard Civel

Co-chairs of the Conference

About GCET

Global Conference on Environmental Taxation

The Global Conference on Environmental Taxation (GCET) has been held every year since 2000 as an international meeting of environmental taxation specialists and a forum for the exchange of ideas and research findings on environmental taxation and other market-based instruments designed to protect the environment and foster sustainability.

The annual conferences provide an international and interdisciplinary setting to explore theoretical and practical issues concerning the design and implementation of environmental taxation. They are not intended to advance any particular environmental agenda but seek to advance knowledge and foster understanding and debate. The conferences bring together experts from many countries, representing a wide range of disciplines (law, economics, finance, environmental science, political economy, and more), sectors (academic, government and non-governmental institutions, and the private sector), and international organizations (such as the UN and OECD). As the conference series travelled around the globe over the years, it has helped build professional networks of colleagues across international boundaries that facilitate the exchange of knowledge during and outside the conferences.

Keynote Speakers

Across four plenary sessions, high-level academics and experienced members of national and international administrations will discuss developments on environmental tarification throughout the world. First plenary session will focus on the two main current challenges for the development of carbon taxation: on the one hand its extension in developing countries, and on the other hand the subsidies to fossil fuels, which create a negative taxation offsetting many carbon pricing initiatives. Second plenary session will discuss the evolution of EU ETS regulation and the coming introduction of Carbon Border Adjustment Mechanism. Third session will be dedicated to compensation challenges for the agricultural and forestry sectors. Fourth session will lastly focus on the importance of the preservation of biodiversity and its economic impacts.

More keynotes speakers will be confirmed in the coming weeks.
