In 2025, a total nominal amount of EUR 2.66 billion was issued in auctions, EUR 0.61 billion in OLO86 and EUR 2.06 billion in OLO96.
That amount has been allocated proportionally among the various categories of eligible expenditure already identified at federal level (i.e. rail transport (rolling stock and infrastructure), development cooperation, tax deductions for green investment, bike allowance, etc.).
Finally, the impact of all of these expenses on the environment, in terms of avoided GHG emissions, was calculated at 613.2 kt CO2e.
