The difference between the BCR in a climate change and a “business-as-usual" scenario leads to a climate change relevance score, which provides an indication to policy-makers and managers of the change in importance of a particular programme if climate change is factored in. Pilot analysis suggests that the consideration of climate change increases the benefit of programmes managed by the Ministry by between 10 and 20 percent. An assessment of a major new investment in improved water distribution and diversion resulted not only in enhanced budget justification for the project but also informed redesign of diversion canals and flood control systems (UNDP, 2015). The analysis could support requests for funding from the Ministry of Economy and Finance, which introduced in 2016 a requirement in the national budget guidelines that climate-relevant programmes be identified (see Cambodia Climate Change Alliance, 2015 and Government of Cambodia, 2016).
