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.

ESG quality and financing costs
Green/social bonds, high ESG scores
Tendency towards slightly lower financing costs (typically a few to ~10 to 20 bp advantage in studies)
Average ESG profiles
Little to no deviation from the reference spread
ESG downgrades, high emissions, brown sectors
Temporarily ~10 % higher loan spreads; for bonds in energy-intensive sectors additional bp premiums

CO₂ intensity of the German power mix

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?
A structured sustainability report delivers a triple return - from the same work.
- Companies with a credible ESG profile save measurable interest today - market reality, not a forecast.
- Banks and customers ask for sustainability data regardless - for SMEs usually via the voluntary VSME standard, not CSRD.
- The triple return: better terms, happier investors and less regulatory risk.

Frequently asked questions on green bonds, reporting duties and ESG financing
What is the CSRD and who is subject to the reporting duty?
The CSRD obliges companies to report on sustainability under the ESRS. Since the Omnibus directive, published in the Official Journal on 26 February 2026, the obligation applies only to companies with more than 1,000 employees and more than €450 million net turnover, both criteria together. Large capital-market-oriented companies have reported since FY 2024; the second wave reports for the first time on FY 2027 (report in 2028). Listed SMEs have been removed from scope. For everyone else, the voluntary VSME standard becomes the reference framework that banks and large customers ask for.
What is a green bond and how large is the market?
A green bond is a bond whose proceeds are used exclusively for climate-friendly projects. The outstanding stock of sustainable bonds in the euro area grows double-digit each year. Issuers benefit from a greenium (interest advantage) of on average 5 to 10 basis points. The dashboard shows the current market volume.
How does an ESG rating affect financing costs?
Companies with an ESG rating of AAA-AA pay 15 to 25 basis points less than the reference rate. BB-rated companies, by contrast, pay 5 to 20 basis points more. On a loan volume of €5m this can be up to €125,000 in interest difference per year.
