How ESG Impacts the Valuation of Commercial Real Estate

Traditional commercial real estate valuations focused on core indicators like location, lease structure, tenant profile, and technical condition. ESG adds a new strategic layer – evaluating how assets perform environmentally, socially, and in terms of governance. 

Green-certified buildings (BREEAM, LEED, DGNB) are already commanding premium pricing, while non-compliant assets face increased risk exposure, capital expenditure burdens, and discounting – the so-called “brown discount.” This gap is widening, especially in core office and logistics sectors across Europe. 

Valuers are increasingly incorporating ESG factors into the core of their methodologies. Here's how: 

• Income approach: ESG-aligned assets often attract higher-quality tenants, lower vacancy rates, and lease premiums – especially from corporates with sustainability targets. 
• Cost approach: Operational efficiencies from sustainable design reduce service charges and maintenance costs, positively impacting value. 
• Risk-adjusted returns: Poor ESG performance increases perceived risk, which may trigger higher capitalization rates. 
• Capex consideration: Properties requiring major retrofits to meet upcoming standards (e.g. energy performance) are often discounted due to expected costs. 

ESG is now central to underwriting criteria. Banks, funds, and pension investors are embedding ESG into acquisition screening, development decisions, and asset management strategies. Across CEE, we are seeing a growing valuation differential between ESG-compliant assets and those that lag behind. And this isn’t a future scenario – it’s already impacting transactions, refinancing terms, and exit yields. 

Strong ESG reporting and performance have become a competitive edge. For investors and owners, this means: 

• Better financing terms thanks to proven sustainability credentials 
• Higher tenant appeal with properties that meet corporate ESG mandates 
• Improved risk management through clarity on energy, emissions, and regulatory exposure 
• Portfolio resilience against future tightening of environmental legislation
