Webinar: Making B£ST better

This webinar will introduce the latest version of B£ST - CIRIA's tool to estimate the benefits for blue-green infrastructure.

A demonstration of CIRIA’s updated Benefits Estimation Tool for blue-green infrastructure


Blue-green infrastructure (BGI), including sustainable drainage systems (SuDS) and natural flood management (NFM) provides multiple benefits ranging from public health to minimising the risks of flooding. These systems based on NFM and SuDS provide significantly more benefits than those expected from a conventional, piped approach to drainage or traditional flood management infrastructure. This is possible because SuDS and NFM invariably enhance the area being developed and contribute to economic development and environmental quality.

CIRIA has developed B£ST as a tool and guidance (W047) to support practitioners estimating the benefits that BGI can create. Valuing the type and magnitude of these benefits can otherwise be difficult, often requiring specialist economic inputs. Questions are often asked about the benefits BGI solutions may bring, their size and their value. Understanding these benefits can help to identify interested stakeholders and encourage a partnership approach to funding schemes.

B£ST provides a structured approach to evaluating a wide range of benefits. It follows a simple structure, commencing with a simple screening process and qualitative assessment to identify the benefits to evaluate further. Where feasible, it provides support to help quantify and monetise over 19 benefits and provides a variety of ways for this information to be presented and shared.
