Urban Green Infrastructure, broadly defined as natural or semi-natural systems within the urban environment, is generally recognized to deliver multiple social, environmental and economic benefits and is seen as a low-risk multi-purpose adaptation measure to climate change. However, policy- and decision-makers locally, nationally and globally lack reliable data and tools for assessing and understanding the full costs and benefits of green infrastructure, which stalls the uptake and limits the access to funding for Green Infrastructure development in cities. The application of whole-of-life approaches to Green Infrastructure evaluation is a potential viable methodological basis for holistic assessments of the full value of Green Infrastructure accounting for the entire range of ecosystem services it provides.

The presentation will provide an overview of the current developments within whole-of-life approaches and methodologies for assessing Green Infrastructure, their coverage, practical applications as well as key gaps and challenges. It aims to introduce practitioners and decision-makers to the potential of the approach and its possible applicability in real-life situations. A discussion on the directions for further co-designed methodological developments and research will be encouraged. Local authorities and project developers or funders interested in gaining an understanding of the value of their existing or planned Green Infrastructure are especially encouraged to attend.

The background study applied systematic scoping and state-of-the-art review methodologies to map the emerging academic and grey literature on assessing whole-of-life costs and benefits of Green Infrastructure and gathered practitioner inputs ranging from local governments to funding institutions that provide targeted funding for Green Infrastructure projects. The study maps the current state-of-the art of this novel field within its broader context and provides a systematic overview of emerging methodological approaches and developments as well as their application in practice up to date. It identifies possible steps forward to advance applicable whole-of-life approach methods and tools for holistic assessments of the value of Green Infrastructure with the broader aim to promote wider uptake of Green Infrastructure including as an adaptation measure, support the business case for Green Infrastructure, stimulate investments and enhance the understanding and awareness of the full value of Green Infrastructure in cities.
