Heat networks supply residual or renewable heat to homes through a collective infrastructure, replacing natural gas for space heating. In the Klimaatkansenkaart Gelderland 2025 (Gelderland climate opportunities map), this built-environment solution accounts for 503 kton CO₂-eq of reduction potential towards 2030, ranking eighth in the top 15.
In the domain table of the 2025 map layer, the same 503 kton stands as the leading reduction solution for the built environment, a domain that currently realises about 23% of its potential. That makes the heat network the largest single lever in a sector where insulation (285 kton) and heat pumps in non-residential buildings (489 kton) complement delivery. Because heat demand, sources and network are interlinked, neighbourhood-level planning determines the pace. Source: Klimaatkansenkaart Gelderland 2025, New Economy (March 2025).
