ETS-2, CO₂ prices and billions in investment: Why the time for energy-efficient refurbishments is now

The debate about rising CO₂ prices in the real estate industry is gathering pace - not least due to our latest data analysis, which was published in the HandelsblattMerkur.de and the Frankfurter Rundschau, among others. The result: in the worst-case scenario, owners and investors will have to prepare for a drastic increase in the price of fossil heating energy, with CO₂ prices of up to 130 euros per tonne by 2030, and even up to 400 euros in the long term.

This development is based on the introduction of the Europe-wide ETS II emissions trading system, which will replace national emissions trading from 2027. For building owners, this not only means new price dynamics, but also one thing above all: increasing pressure to take action to renovate buildings in an energy-efficient manner - in a planned, data-based and economically efficient manner.

ETS II: Climate protection with market logic

With ETS II, the EU is drawing a clear line under fragmented national solo efforts. Instead of fixed minimum CO₂ prices, the new system is based on market principles: In future, supply and demand will determine certificate prices, capped by a price stabilization mechanism. This will create transparent, reliable framework conditions for companies and private households. At the same time, a CO₂ budget will become binding for the building sector.

"Carbon pricing via ETS II finally creates a fair, pan-European framework for the building sector. Those who invest now will benefit twice over: through lower operating costs and sustainable value appreciation," explains Daniel Schreiner, Head of ESG & Construction at Purpose Green.

Billion-euro investments planned in Berlin

A look at the capital also shows just how concrete the need for action is: according to Rundfunk Berlin-Brandenburg (rbb24) Berlin's housing associations (including Gewobag, Gesobau and degewo) are planning refurbishment investments of over 3 billion euros by 2030. Around 275,000 apartments are to be modernized in terms of energy efficiency in order to achieve the state's climate targets.

The signal effect is clear: those who do not act now risk economic disadvantages. Pressure is growing not only in the public sector, but also on the free market, to make real estate fit for the future for regulatory and ESG reasons. Those who opt for the wrong strategy or wait too long not only risk high follow-up costs due to rising issue prices, but also the loss of value potential. Energy-efficient refurbishment is becoming a key factor in the sustainable management of real estate portfolios.

The Green+ Portal: Our software solution for energy-efficient refurbishment - from analysis to subsidies

But how can this transformation be managed efficiently? This is exactly where our Green+ Portal comes in, a holistic software for energy-efficient refurbishment that combines CO₂ analysis, ESG assessment and technical refurbishment planning, including subsidy analysis, on a single platform.

With the Green+ Portal, Purpose Green offers the first comprehensive platform solution for strategic and technology-supported decarbonization.

Conclusion: Invest in refurbishment now - and secure the future

Rising CO₂ prices are no longer a theoretical debate, they are a reality. The introduction of ETS II is fundamentally changing the playing field. Both public and private owners are called upon to take action now. Those who rely on data-supported planning and intelligent software solutions at an early stage will meet EU requirements in a targeted manner with energy-efficient refurbishments and protect the long-term value of their portfolio.
