I'm modelling a fishing activity which include some antifouling paint emissions in the ocean. My problem is that I cannot select any provider for the output "antifouling paint emissions". I compared my results with SimaPro and I get much lower marine toxicity impact because of that. Do you know how to fix this issue?

Thanks for your time!

Providers are only selected when the output is a product or waste flow. In your case it sounds like "antifouling paint emissions" should be treated as an environmental flow - a direct release to the environment with no further modifications.

If this is a brand new flow you are creating, you can then add it to your LCIA method with whatever characterization factor is appropriate, or use the characterization factor from another database such as what you are using in SimaPro.
