GCET27 Call for submissions
Abstract submission deadline: 15 April 2026
Please submit here
The Potsdam Institute for Climate Impact Research (PIK) invites the submission of abstracts for the 27th Global Conference on Environmental Taxation (GCET27) to be held in person in Berlin, Germany, from 14 to 16 September 2026. The central theme of this year’s Global Conference on Environmental Taxation (GCET) is Fiscal Instruments for International Climate Action. For more information visit our conference website www.gcet27.de
The Global Conference on Environmental Taxation is an international, interdisciplinary forum to advance knowledge, understanding, and debate on environmental taxation and its relationship to other environmental protection policies. The conference is not intended to promote a particular advocacy agenda.
GCET27 will bring together researchers and practitioners working at the intersection of public finance, climate and environmental economics, tax law, international economic law, and climate policy. The programme will combine invited keynote lectures, policy-oriented panels, and parallel paper sessions aligned with the three-day structure of the conference
How the theme connects to the programme
Environmental Taxation and International Climate Finance is central to the design and political feasibility of climate policy. GCET27 invites contributions on novel approaches to climate finance, including results based finance, as well as analyses of the effectiveness, obstacles, and context specific features of climate policy in practice across countries, with a particular focus on carbon pricing. This includes work on how taxes, carbon pricing, subsidy reform, and related market based instruments can mobilize resources and shape incentives, and on the conditions under which they do not, and what this implies for an effective and fair transition consistent with the Paris goals.
The agenda will particularly highlight
- Day 1: International environmental taxation and cooperation, including climate clubs, tax coalitions and cross border coordination
- Day 2: Climate finance and just transitions, including implementation perspectives from international institutions
- Day 3: Implementation, sectors and law, including hard to abate international sectors and legal and trade interfaces
Scope of submissions
We invite abstracts on the conference theme and on environmental taxation and market-based instruments more broadly. Abstracts that directly address the theme will be given priority in the selection process.
Topic areas include (but not limited to)
- International climate finance and fiscal policy instruments for mitigation and adaptation
- Carbon pricing, effective carbon rates, emissions trading, and interactions with the broader tax system
- Climate clubs, and international cooperation on pricing, minimum standards, and revenue use
- Tax coalition and coordination mechanisms for raising funds for global public goods (e.g. international aviation taxes, maritime shipping taxes, corporate income taxes)
- Carbon border adjustment, trade exposure, leakage, and international policy coordination
- Subsidy reform, green fiscal reform, and revenue recycling, including distributional impacts and acceptability
- Climate policy in developing and emerging economies, including tax reform, administration, and political economy
- Sectoral instruments, including international aviation and maritime shipping, fuels, and transport taxation
- Legal and institutional dimensions, including international tax rules, environmental law, and governance
- Just transition design, compensation mechanisms, and the social incidence of environmental taxes
- Evaluation, modelling, empirical evidence, and policy learning across countries
Publication Opportunity Critical Issues
Presenters at GCET27 will have the opportunity to submit their papers for possible publication in Critical Issues in Environmental Taxation. The Call for Papers for Critical Issues will be sent very soon after the end of the conference. Final versions of manuscripts accepted for publication in Critical Issues must meet the Edward Elgar publishing guidelines. More information can be found on the GCET27 website.
