Hi, pardon me if my question is very naive as I am very new to One Click LCA. My question is, if we are to use a material that is not readily available for example, concrete with rice husk ash, how do we include that? what could be the easiest way? Any help would be greatly appreciated.

Hi there,

welcome to our community and thank you for your post!

There are two different approaches depending on the situation.

SCENARIO 1:

- You **have an EPD** ,
- _AND_: if you search for it in one of your tools that allow for the same data standard (see definitions [here](https://oneclicklca.zendesk.com/hc/en-us/articles/360015036980-Impact-Assessment-Categories-CML-TRACI-and-PEF)) that is used in the EPD, you **cannot find it**
- _AND_: You checked that the EPD is **[valid for the inclusion](https://oneclicklca.zendesk.com/hc/en-us/articles/360015064799-How-to-Check-If-Your-EPD-is-Valid-For-inclusion-in-One-Click-LCA)** in OCL-database

→ Please send the EPD (at best as .pdf) to [support@oneclicklca.com](mailto:support@oneclicklca.com). We will forward it to our Data Team and will let you know once it has been uploaded.

SCENARIO 2 (only for users with **Expert** and **Designer** licenses):

- You have an EPD that **doesn’t meet OCL criteria** for inclusion (see here), e.g. a project-specific or internally verified EPD
- _OR_: You have an EPD that meets the OCL criteria for inclusion, but you need to **use it right away** in your calculations

→ You can add this EPD as a [private datapoint](https://oneclicklca.zendesk.com/hc/en-us/articles/360015226180-Adding-Private-Data) to your [company account](https://oneclicklca.zendesk.com/hc/en-us/articles/360014816379-Setting-Up-a-Company-Account).
