Company Overview

Retta is the largest professional service group in the Nordics specializing in the brokerage and management of apartments, properties and offices. Retta provides its customers with comprehensive services and solutions in real estate services for the housing and office space sectors.

Problem Statement

Real estate accounts for up to 40% of the global carbon emissions, which means that focusing on reducing these emissions can have major benefits.
