A BC3 model helps understanding if Pays policies can be progressive

Two politically sensitive reforms
The proposed Energy Taxation Directive (ETD) reform and extension of the Emissions Trading Scheme to buildings and road transport (ETS2) are two of the most politically sensitive elements of the European Commission’s Fit for 55 legislative package.
On one hand, the proposals would significantly expand the application of the polluter pays principle across the EU, eliminating swathes of fossil fuel subsidies and capping emissions in two laggard sectors in the energy transition. But on the other hand, given that energy costs constitute a higher share of expenditure of lower-income households, who are less able to change consumption behaviour in response to higher prices, many stakeholders are concerned that the proposals risk entrenching inequality.
New evidence of progressive distributional impacts
A microsimulation model developed by the Basque Centre for Climate Change (BC3) with IEEP and five other partners in the Think Sustainable Europe (TSE) network assesses the direct, overnight distributional impacts of both measures on households. If carefully designed – including well-directed revenue-recycling, and alongside complementary policy measures – the proposals can achieve clearly progressive impacts. In short, they could serve as a tool to fight both inequality and the climate crisis.
