“The fossil fuel industry is causing and accelerating the climate catastrophe! “

  • Making colossal profits over decades
  • Reimbursing its wealthy stakeholders
  • Investing in more fossil fuels
  • Not embracing the transition away from fossil fuels

We have a capital allocation issue!

No causality between electricity price and corporate tax level

  • Conventional carbon taxes are targeting consumers:
                  • this is a regressive tax: the least well off pay relatively more
  • Taxing the profits is hitting the wealthy owners - a progressive tax:
  • no ‘cost pass through’

“… during commodity booms, i.e. when prices are extraordinarily high, and when windfall profits occur as is the case now,  extractive groups book a higher share of profits in tax havens.”

ITO lesson learned from the 2022 EU solidarity contribution is that windfall profits are more effective if the tax is levied on ‘consolidated global profits’. 

“In this paper, we calculate the excess profits of energy and fossil fuel companies in the EU during the energy crisis on 2022-2023. A windfall tax on these profits was adopted, which we find could have generated e 73.8 billion, nearly three times the officially reported collection. We document evidence for an avoidance response by large multinationals shifting

profits to jurisdictions where the windfall profits tax was not in force.”

International tax cooperation: UN Tax Convention to the rescue!

  • Global tax measures have to fit with the global climate efforts – both on international climate finance and tax justice objectives and processes
  • Fair rules at the global level must serve sustainable development, implemented via the UN Tax Convention: environmental, social and economic justice issues belong together
  • Incorporate polluter pays principle provisions the guarantee progressive environmental taxation measures, including on polluting capital

The UN Tax Convention is historic opportunity to combine tax justice and climate justice

Surtax on fossil fuel industries’ global profits

  • a surtax on the global profits (net income before tax)
  • on national, regional and global level under unitary taxation
  • included in the UN Tax Convention
  • starting at a surtax rate of 20%, increasing over time
  • supply-side measure targeting capital allocation and the costs of capital …. not consumption
  • carrying transformative incentives to overcome carbon lock-in and fossil fuel incumbency
  • proceeds earmarked for climate finance, e.g. UNFCCC obligations
  • … more than USD 1 trillion in revenues if collected since the adoption of the Paris Agreement
