Call for Abstracts: Fiscal Instruments for International Climate Action

We are pleased to announce that the Call for Abstracts for GCET27 is now open!

GCET27 will be hosted by the Potsdam Institute for Climate Impact Research (PIK) and held in central Berlin at the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW).

The conference theme, Fiscal Instruments for International Climate Action, focuses on how fiscal instruments such as environmental taxes, carbon pricing, subsidy reform, and related market-based approaches can mobilize resources and shape incentives for an effective and fair transition consistent with the Paris goals.

  • 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

  • Evaluation, modelling, empirical evidence, and policy learning across countries
