From Complex Data to Actionable Insight
About SwissClimmo
Considerable quantities of relevant climate and air quality data exist in Switzerland. However, these datasets are large and complex which, until now, has severely impeded their use across the real estate sector.
SwissClimmo bridges the gap between state-of-the-art climate science and accessible local information — helping mortgage lenders, valuers, and financial institutions meet growing regulatory expectations around climate-related disclosure, while also serving many other stakeholders including estate agents, property search platforms, architects, urban planners, sustainability consultants, property developers, and private individuals.
To achieve this, we draw on deep expertise in geospatial data analysis, environmental science, and scientific computing to produce high quality, easy-to-interpret insights.
