Bombas gives no Scope 1, 2 or 3 figure; the Commons says it measures emissions with a third party but does not share the numbers. It publishes no emissions figure, so the size deduction (0.70x) applies. No renewable electricity information and no reduction target were found. The Commons found no detail behind its 100% recycled packaging claim, and its take-back bag with For Days shares no results. B Corp certification since December 2017 is not evidence of reductions, and donating an item for each one sold is a social programme. No environmental regulatory action was found; a federal lobbying filing naming it could not be read.
