Environment Analyst invites you to their event

Counting what matters – what do we really mean by ‘best-value’ solutions?

About this event

In response to the global climate and biodiversity crises, Ofwat has stipulated that a catchment and nature-based solutions (NbS) approach should be used and evaluated through a total value framework to derive ‘best-value’ rather than lowest-cost solutions. The hope is that this will result in more NbS as preferred options. Whilst this is a great first step, the body of evidence as to NbS’ cost and reliability is patchy. There is also a perception that NbS are a cheaper alternative to ‘grey’ infrastructure, yet at present they can be more expensive to implement, operate and maintain than traditional solutions.

To tip the scales towards NbS, we need to properly account for their wider benefits and, in some cases, the unintended consequences of grey infrastructure.

This Sustainability Delivery Group Expert Talk, part of 'The OneWater Approach series' held in partnership with Jacobs, will explore the positives and negatives of the current ways of assessing ‘total value’, and where we need to get better evidence to provide a more robust analysis.
