Forest Calculator – Open Forestry Impact Evaluator

Last updated: 23.8.2025

The project initiated a web tool helping forest owners reduce water pollution, increase the carbon sink, and improve forest value.

This joint project between The Association for Continuous Cover Forestry in Finland,  Natural Resources Institute Finland, Forest Service Arvometsä, and outsourced partner Avoin developed a free online forest calculator to help landowners compare the water quality, carbon impact, and profitability of different forestry methods. Using open forest data, it provides site-specific insights to support sustainable forest management, particularly on peatlands where clear-cutting and ditching cause significant nutrient leakage into the Baltic Sea.

Status and news

The service is in active use in Finland. We are looking into expanding it intoa supporting more comprehensive use cases benefiting from extensive national statistics and forest models.
