This one-page report contains my computation of our our total (direct + indirect) household carbon footprint for 2022.

We needed to buy about 4.5 tonnes of CO₂ to achieve net zero emissions for the year. This amount was somewhat larger than last year primarily due to reduced solar PV exports resulting from lower solar production under the prevailing La Nina weather conditions.
