Why it's on ClimateTicker

Jan De Nul is a genuine critical enabler of renewable energy infrastructure — its offshore wind installation and subsea cable-laying fleet underpins European and international energy transition projects. However, it is primarily a construction and dredging contractor whose own operational footprint is large and carbon-heavy, and its diversified revenues still include oil, gas, and port infrastructure services that dilute the pure-climate narrative.

enablerJan De Nul earns revenue by contracting marine installation, dredging, civil engineering, and environmental remediation services globally; offshore energy (wind foundations, cable installation) and dredging together account for approximately 85% of turnover.
