Is Climate Risk Changing the Cost of Ownership in Portugal?

The large coastline, dramatic cliffs, and golden sand beaches are a magnet for lifestyle buyers and property investors. However, the rising sea levels, recent heat waves, and costal erosion are creating different dynamics for Portugal’s real estate market.

Climate risks can change the cost of ownership in Portugal through rising insurance, higher borrowing costs, and renovation expenses.

From the sunny Algarve to the Silver Coast, coastal properties can be prone to extreme weather events, like storms, flooding, and infrastructure damage. Here is how climate change can affect ownership costs and some extra tips on finding resilient properties.

Understanding Climate Risk in Portugal

The effects of climate change can be felt around the world, and Portugal is no exception. As part of the Iberian Peninsula, the country has a Mediterranean climate and around 2,500 km of coastline.

According to the Portuguese Environment Agency (APA), 25% of the mainland’s coastline is receding and the shoreline moves inland by 2 meters annually in some areas. Factors like rising sea levels and lower sediment only add to the risk.

Climate risks, especially heat waves, floods, and coastal erosion, are emerging as a variable in Portugal’s real estate market. They can create financial risks for ownership costs through changes in the property’s lending, asset value, and resale opportunities.

The Banco de Portugal (Bank of Portugal) groups climate-related financial risks in two categories: Physical risk and transition risk.

• Physical risk comes from the physical effects of climate change. It can be acute (such as floods, storms, and wildfires), or chronic (such as drought, increasing temperatures, or rising sea levels). For property owners, these risks can damage a building, home market value, and impact their insurance coverage.
• Transition risk comes from the shift to a low-carbon economy. For homeowners, this risk has to do with energy efficiency, changing consumer preferences, regulatory requirements for inefficient buildings, to name a few.

Climate Change and Property Insurance in Portugal

About 19% of residential properties have earthquake insurance, although Portugal is in a high-risk seismic area, estimates the Portuguese Insurance and Pension Funds Supervisory Authority (ASF).

A separate 2026 OECD Economic Survey showed similar results. The survey found that insurance coverage for climate risks in Portugal is low. Around 3% of losses from extreme weather events in the country were insured between 1980 and 2024.

In Portugal, insurers use risk-based pricing, which means properties in vulnerable areas often have premium prices.

Energy Efficiency and Running Costs

Energy certification can affect the physical and transition risk of a property in Portugal. Buildings with energy ratings of B to A+ often perform better during extreme temperatures due to lower running costs, better resilience, and higher resale values.

Properties with an F or E certification tend to require higher upfront costs. Older buildings often need window replacement, thermal insulation, effective heating or cooling systems, and other upgrades.

Portugal’s Energy Performance Certificate (EPC – Certificado Energético) can show you the class that your property belongs to.

Climate Risk on Mortgage Lending in Portugal

European banks take into account the energy performance when they provide loan offers, according to a study from Aalto University. Few property buyers understand how a poor energy rating can affect their ability to receive a mortgage.

Banking experts estimate climate risks, mainly wildfires, floods, and extreme weather, to become a major factor in financing homes and commercial properties. However, the lender’s perception depends on the location of the asset and the area the bank operates.

Mortgages in Portugal are available to foreigners, with average LTV of 65% to 75% for non-residents and about 80% to 90% for Portuguese residents.

Which Areas Face More Climate Risks in Portugal

Coastal properties in municipalities like Lisbon, Oeiras, and Cascais, could be more vulnerable to coastal erosion and rising sea levels, while inland regions, such as Loures and Sintra, can experience wildfires on rare occasions.

Developments closest to the Tagus River, Douro River, or Minho River might experience flooding. Buying property in Lisbon‘s historic neighborhoods, such as Chiado or Príncipe Real, could be beneficial due to its elevated locations and urban density.

How to Use Climate Risk as a Competitive Advantage

Investors who can spot resilient buildings, good energy efficiency, and estimate the renovation costs can enjoy a competitive advantage. Thorough due diligence can help buyers assess the climate risks when buying property in Portugal.

Portugal real estate investment can be a wise choice as the housing market provides effective long-term prospects for climate-aware investors. The country’s impressive progress on renewable energy, EU funding for sustainable developments, and climate-resilient investment programs, continue to attract foreign and local property buyers.
