Quantifying carbon footprint for ecological river restoration

Abstract RIVER restoration is a popular technique to rehabilitate degraded river habitat. Given the nature of these types engineering projects, using ecological indicators monitor effectiveness has been traditional approach. However, as this approach emphasizes post-project performance, environmental impact attributed project’s construction phase received little attention directly or indirectly. This study quantified carbon footprint restoration, project in California case study. A topographic diversity index (TDI) was developed functional unit project, indicating how can increase variation habitat topography. The results show that lead greenhouse gas emissions ranging from 288 336 kg CO 2 equivalent (kg e) for every 1% TDI improvement, 9–14 e per meter stream restored. identified improving raw material acquisition plans and heavy-duty equipment rental decision be feasible strategies leading reduction footprint.
