The CO₂ price is central for assessing fossil-fuel exposure. Rising EUA prices directly raise the cost of Scope 1 emissions and make green investment relatively more attractive.

Article 9 (Deep Green) shows persistent net outflows – greenwashing scepticism and a stricter interpretation are weighing on the category. Article 8 (Light Green) is benefiting.

CO₂ intensity of the German power mix
357gCO₂/kWh
Source: Ember Energy
The CO₂ intensity of electricity is central for Scope 2 emissions. A lower value means: every kWh of on-site power from PV or a heat pump saves more CO₂.
EU benchmark 2030: < 100 gCO₂/kWh.
What does this mean for your financing strategy?
Experience shows: companies with a credible ESG profile are already saving measurable interest today. A BBB ESG rating still costs nothing – but a poor rating already makes capital noticeably more expensive. The CSRD reporting duty is coming anyway. Those who report in a structured way now turn the same work into better financing conditions, happier investors and less regulatory risk.
