Contest on visualization of sustainability assessment data

Now more than ever we need high-quality sustainability assessment to avoid the climate and other environmental crises. However, this research community is hindered by a lack of expertise in information visualization. You are cordially invited to participate in an open contest on the visualization of sustainability assessment data. With a prize fund of €2000, this could be your chance to help people make better decisions through information visualization, while also earning a nice reward! The contest Github repo is https://github.com/Depart-de-Sentier/visualization-contest-2022, and this includes the example input and results data, the contest rules, and the submission procedure. Please note the following:

• The submission deadline is January 16, 2023, at 12:00 UTC.
• The contest prize fund is sponsored by the ecoinvent association (https://ecoinvent.org/)
• Contest entries must include working open source code such that your ideas can be used in sus

Brightway ❤️ SimaPro

SimaPro CSV is a standard format for data interchange, but is currently difficult to import into Brightway due to the following:

• The list of elementary flows in SimaPro differs from that used in ecoinvent (which is the base data in Brightway). While there are matching lists from GLAD, these lists do not include SimaPro. Note that there are two difficulties here: a) SimaPro fixes some naming weirdness in ecoinvent, which results in different names; b) SimaPro includes additional flows which don't have direct matches in ecoinvent.
• The formula language in SimaPro is mostly Python compatible (i.e. can be eval-ed). However, there are some functions which need to be rewritten, and I don't have the SimaPro formula language specification.
• SimaPro adapts some modelling concepts from ecoinvent; the most prominent is to change the system modelling of waste treatment to make the numerical signs more reasonable. These values n
