Congratulations! You’ve presumably gone to some trouble to calculate your household’s carbon emissions, and this forum is for you to discuss your results with fellow users. You probably also have some ideas about features you would like to see added, deleted, or tweaked. In designing a calculator, we had to balance claims made on your time against desire for precision. IEEE Spectrum sought a reasonable balance, but please tell us how you think we can do it better.
