Amesto is a Nordic accounting, software and professional services firm with small operational emissions. It reports Scope 1 to 3 emissions, but has no supplier engagement strategy, limited climate targets and little nature or waste disclosure. Its governance and reporting are stronger than its decarbonisation commitments, which go little beyond operational reductions.
