It also shows how we can use satellite imagery to estimate their carbon storage potential. By knowing where our salt marshes are – the Nordic region is better suited to manage these coastal areas sustainably. A step towards achieving our Nordic Vision to become the most sustainable and integrated region in the world by 2030.
