Ipieca and IUCN have developed this set of guiding principles for marine net positive impact (NPI) in the energy industry to address the unique challenges of delivering net positive impact for energy projects in the marine environment (Figure 1). The principles aim to help companies operating in the marine environment, and other interested stakeholders looking to turn ambition into credible, lasting gains for marine biodiversity.

This document is a companion guide to the Regenerative Roof Scorecard, a decision-support tool developed by IUCN in collaboration with Holcim, with technical leadership from Second Nature Ecology + Design, and industry testing with Zinco. The Scorecard evaluates regenerative roof designs in two areas: site-based benefits and embodied impacts. Site-based benefits include biodiversity support, health and well-being, climate change adaptation and mitigation.
