Correction to: Nature Food https://doi.org/10.1038/s43016-024-00949-4, published online 1 April 2024.

In the version of the article initially published, the right y axis of Fig. 1c was incorrect and has now been amended to “CO2 intensity (kt CO2 eq kt−1)” in the HTML and PDF versions of the article. This change does not affect any calculations, results or conclusions of the article.
