We have developed an assessment tool, to assist us in making our capital investment more sustainable and carbon efficient. The Carbon and Sustainability Assessment Tool (CAST) allows us to compare different solutions in terms of the contribution over their lifetime to carbon emissions and overall sustainability. The tool was fine-tuned on the real life example of our sludge strategy, highlighting the option of maximising use of our existing sludge incinerator, rather than constructing an additional one. We are starting to make use of this tool in our planning for our next five-year investment cycle. We are running the detail of bespoke solutions through the model to help in our decision making, and we are using CAST to generate carbon curves for more generic investment for use in the cost estimating stage.
