Pimachiowin Aki World Heritage Project Area Ecosystem Services Valuation Assessment

This executive summary describes an economic valuation of ecosystem services within the proposed Pimachiowin Aki World Heritage site, conducted by the International Institute for Sustainable Development to support a UNESCO application. The assessment aims to demonstrate that the site's natural state provides higher value than current economic activity suggests, focusing on services such as carbon sequestration, air and water filtration, and recreation.

• The report provides conservative monetary estimates for specific services, including air filtration based on a value of $6.66 per tree, and the protection of natural landscapes based on a willingness to pay of $503 per household in Manitoba to double the size of protected areas.
• The estimated values are intended as a conservative baseline to initiate discussions with international, national, and local stakeholders rather than as perfectly accurate figures.
