Notpla's core product—seaweed packaging—delivers genuine nature and waste benefits, but the company's sustainability claims rest almost entirely on product design rather than operational rigour. Missing: quantified Scope 1/2/3 emissions, renewable energy targets, formal GHG reduction commitments, and a credible emissions trajectory despite rapid growth. B Corp certified and controversy-free, but transparency gaps are material.
