The International Monetary Fund is calling for a carbon tax on aviation and shipping to help deliver global climate goals, The Guardian reports. A charge of $30 a tonne on carbon dioxide embedded in international transport fuels could have raised $25 billion in 2014, the influential Washington DC-based body estimates.
In a report released after 195 countries struck a UN climate pact in Paris, it said carbon pricing should be “front and centre” in efforts to curb global warming. Levies on so-called bunker fuels were “promising”, it said, and a possible source of climate finance – support for developing countries to go green and adapt to shifting weather patterns.
Emissions from planes and ships, around 4% of the global total and rising, were not directly addressed in the Paris agreement. It is up to the UN-backed authorities, the International Civil Aviation Organization and International Maritime Organization respectively, to regulate the international sectors.
The IMF noted there were “challenges” to imposing a levy, including the need for international coordination and legal issues, “but the practicalities should be manageable”.
