No longer a bonus, but mandatory

Is the heyday of sustainability already over? What was once a new departure and a will to shape the future is increasingly losing weight in day-to-day operations. Short-term solutions are being prioritized among cost, market and usage issues, while structural decisions are being postponed. Yet now is precisely the time to align real estate portfolios for the future and consistently anchor sustainability in risk management.

From ESG label to strategic reality
Sustainability in the real estate industry has had its noisy years behind it. After gaining a certain reputation as a differentiating feature, it has now taken its place as a strategic core issue in the form of ESG criteria. However, this is precisely why the topic is in danger of becoming quiet between reporting obligations and day-to-day business. What becomes the norm disappears from the limelight. But routine is no protective shield. Especially not in an industry that thinks in decades but often makes decisions in years.

Because while sustainability is being discarded as a done deal in many places, the structural challenges remain. Real estate thinks in cycles of 30, 40 or more years. Net zero by 2050 is therefore not a distant vision, but a real planning horizon. This also means that a large proportion of today’s existing properties can only be properly renovated or completely refurbished once.

Uncertainty as the new planning reality
The current geopolitical situation, volatile markets and unclear framework conditions are currently making it difficult to draw up reliable climate reduction paths. In practice, this often leads to decisions being postponed or reduced to the most favorable short-term solution. However, those who persist in linear thinking are limiting themselves in the long term. Climate protection roadmaps, gray energy, life cycle costs and climate risks must be an integral part of every decision in order to achieve climate neutrality in an economically viable way. And not at some point, but now.

In practice, it is becoming clear that portfolio holders are taking an increasingly differentiated approach to sustainability. In addition to traditional CSR approaches, a clearly risk-oriented approach is becoming established. The focus is on reliable data on condition, consumption and emissions as well as building-specific risk profiles, which are incorporated into the portfolio strategy as control parameters. This makes sustainability a strategic decision-making factor that goes beyond reporting. The location in particular is taking center stage: Real estate must not only be efficient, but also resilient to heat, water, extreme events and social tensions. Those who systematically assess these risks can take targeted action. Everyone else reacts to the consequences later.
