Hello!

I would like to know the source of the on site wastage percentage when United Kingdome has been selected in the LCA parameters.

Thanks!

José

Hi José!

The waste percentages for the UK (if you have used UK-specific wastage) are coming straight from the RICS guidance. If you check page 83, you will find the percentages references. The A5 scenarios also come from the RICS guidance.

You can view the RICS 2nd edition guide right here: [Whole\_life\_carbon\_assessment\_PS\_Sept23.pdf](https://www.rics.org/content/dam/ricsglobal/documents/standards/Whole_life_carbon_assessment_PS_Sept23.pdf)

Let me know if you have any further questions!

Thanks for the feedback!  
It would be nice to update the reference in the data card when the United Kingdome option is selected in the LCA parameters.

Hi José,

In the LCA parameters, we are updating the text to display the source behind the country as currently it just says ‘United Kingdom’ for the wastage scenario.

For the data card, we already display the information but it seems it currently displays the default source instead of the UK source. I have asked our team to look into this, thanks for bringing that to our attention!
