Data Collection – Big Tech Emissions + Energy

Every year, most large tech companies share a PDF (and if I’m lucky, an Excel file) of their greenhouse gas emissions (for their direct operations, for the power they consume, and for the indirect emissions from buying stuff and selling stuff), along with some information about how much energy they consume for their business.

As you know, big tech is facing rising scrutiny for their rising energy consumption, and their rising climate impacts. This collection doesn’t just gather their disclosures: I try to reverse-engineer the adjustments big tech companies are making to their emissions data, to get a clearer picture of their real climate impacts. Sometimes they use carbon offsets, sometimes they use suspect renewable energy certificates – and you end up with headline emissions numbers way lower than ‘unadjusted’, or ‘raw’, figures.

There are complications, nuances, weird exceptions and frustrating obscurity for each of these companies (particularly for scope 3), so please – email me if you are confused. This table shows the report version (the month it was published), the years each version covers, and how many data points exist for that version.

You are free to use this compilation of publicly available data for non-commercial or commercial purposes – but it’s very nice if you attribute it to me, because it takes time to collect and process this stuff 🙂
