For developers and students

Tech challenges, ready to pick up.

Real problems people have written down in open-source issue trackers, developer threads and the gaps in public data. Every one is sourced, has a brief and a builder's kit, and is sized so a first version fits a weekend, a few weeks or a semester.

    A script that pulls monthly generation by source from NL Hydro's PDF reports into a CSV from 2018 to the latest month, and a pull request to Electricity Maps adding a source-based fallback power mix for the Newfoundland zone, with the method written down.

    Web developers using CO2.js can't produce a standard Software Carbon Intensity score for their site.

    Solved looks like

    An sci() function in CO2.js that takes operational emissions, embodied emissions and a functional unit and returns a score, with unit tests based on the SCI specification and a documented page-visit example.
