This brief provides guidance for institutional investors on the use of natural climate solutions (NCS) in corporate climate strategies. Companies in all sectors are increasingly making climate commitments that rely on actions such as forest protection or reforestation to reduce emissions or remove carbon from the atmosphere. Often, these actions are used to offset the companies’ emissions in order to claim net-zero emissions status. NCS are critical to meeting the goals of the Paris Agreement. But their use to  offset corporate emissions is controversial. Investors are increasingly looking for guidance on this topic, given its potential to exacerbate climate risk or create reputational risk if NCS are used incorrectly.
