What is BSI Flex 702 about?

Protecting our natural environment is key to supporting biodiversity and can be achieved by scaling up investment in nature. One approach is through nature markets, which facilitate generating, storing, and trading nature credits. Biodiversity markets, a subset of nature markets, specifically support the variety of living organisms.

BSI Flex 702 adds requirements for biodiversity investment projects to BSI Flex 701’s nature market principles, enabling the integrity of UK biodiversity markets.

Note: BSI Flex 701 establishes an overarching framework and 22 core principles to help guard against greenwashing, support environmental outcomes and boost confidence. You can download a copy of BSI Flex 701 here.
