The IENE 2026 Conference in Bristol will explore how ecological and social values can meaningfully shape infrastructure planning; how innovative financing can support infrastructure that is robust, adaptive, and aligned with the needs of both people and wildlife; how climate resilience emerges from functioning ecosystems and connected landscapes; how effective measures can be delivered rapidly and at scale; how infrastructure must operate within ecological limits; and how competing visions of the future from technology‑driven growth to sufficiency‑oriented transitions shape decisions.
