More and more municipalities are demanding that greenhouse gas calculations be performed already in the planning processes. For property developers like Stor-Oslo Eiendom, it has therefore become increasingly important to have full control over their projects' climate footprint.

The Challenges for a Property Developer

Oslo Municipality, Nordre Follo Municipality, and several other municipalities in Norway now place specific demands that greenhouse gas calculations must be performed when submitting planning proposals. The requirements vary but are quite comprehensive and include materials, planned energy use, construction site operations, and transport. Before Reduzer, this was an unmanageable task for Stor-Oslo Eiendom, and it was both costly and time-consuming to hire external consultants for every single calculation. It was clear that a more efficient solution was needed.

The Advantages

Stor-Oslo Eiendom chose Reduzer to streamline their greenhouse gas calculations. They now perform the calculations internally, with better control and insight into the projects' climate performance. The tool is user-friendly, even without prior climate accounting experience, and has provided the company with several important benefits.

1. Increased Efficiency

Automated calculations save time and costs.

2. Greater Control

Full oversight makes it possible to find measures for emission reduction.

3. Better Decision Basis

Provides support for the selection of materials, methods, and energy solutions.

4. Simpler Reporting

Simple reports show the projects| climate performance.
