Global Carbon Tax: Challenges, Opportunities, and Future Visions
A panel discussion organized by Global Visions ry
As the climate crisis deepens, the need for ambitious, coordinated, and fair climate action has never been more urgent. One idea attracting increasing attention is the introduction of a global carbon tax—a system that would put a price on carbon emissions worldwide, aiming to reduce greenhouse gases while generating revenue for climate solutions. But could such a policy work in practice, and what would it take to implement it on a truly global scale?
This panel will bring together multidisciplinary experts from economics, environmental policy, political economy, and climate governance to explore the feasibility, challenges, and potential benefits of a global carbon tax. We will examine how it differs from other carbon pricing mechanisms, the governance structures and international cooperation it would require, and whether it could also serve as a tool for climate justice by supporting adaptation in Global South countries.
The purpose of this panel discussion is to openly explore the idea of a global carbon tax with a multidisciplinary panel of experts, during which we will discuss the challenges of current carbon tax models and the potential of a global carbon tax in the future.
This event is free of charge and will be held in English. All who are interested are warmly welcome. The panel will be filmed and available on our website in the near future.
