GCET is the leading global forum for interdisciplinary exchanges on the principles and practices of environmental taxation and other market-based instruments for greening the economy and promoting the transition to low-carbon and resource-efficient societies. Research presented at the previous twenty conferences has helped provide a much stronger theoretical and empirical underpinning of the legal, economic and behavioral issues in this area.

We welcome individuals from all parts of the world who are interested in the exchange of ideas, information, and research findings about environmental taxation issues and sustainable economic development, including:

  • Government officials from all levels of administration, including provincial, state, and territorial levels from ministries and departments of finance, taxation, transport, urban design, energy, water, environment, and natural resources;
  • Representatives from international and non-governmental organizations, tax and accounting professionals, private sector executives, and experts; and
  • Academics from universities and institutions of higher education in the fields of law, economics, taxation, accounting, public administration, environmental studies, political economy, engineering, and more.

The annual conferences provide an international and interdisciplinary setting to explore issues concerning the design and implementation of environmental taxes and opportunities for creating networks to explore various theoretical and practical issues. The conferences are not intended to advance any particular environmental agenda. The main emphasis of GCET is to provide insights and analysis on how tax policy can promote sustainable environmental goals.

Recent GCETs have brought together experts from more than 50 countries, representing a wide range of disciplines (law, economics, finance, environmental science and more), sectors (academic, government and non-governmental institutions and the private sector) and international organizations (UN, OECD and EU). Experts gather to exchange ideas on how effective environmental taxation policies can promote the protection of the environment and sustainable economic development. By discussing environmental taxation issues that exist around the world, effective approaches used in one country can be considered and implemented by governmental authorities in other countries.
