Hi Jenna,
Thanks for posting. You're right that Pipeline is intended to replace static portfolio selection. However, Pipeline only works with data that's on our platform, and we unfortunately don't have the environmental data that you're using to calculate sustainability.
It is possible to use external data on our platform through Fetcher. Fetcher requires multiple rows of data for each stock, each row marked with the date that that data became available. If you have access to the environmental data you used in CSV format with multiple dates and data points for each stock, you could import that data into the backtester and do your calculations there. Or if you could change the CSV on the website to have dates as I described, you could use Fetcher on that. However, if that is too difficult, it seems like it would be fine for you to use a static portfolio in this case.
