Environmental Stakeholder Committee
Experts from notable conservation and scientific organizations serve on ISSF’s Environmental Stakeholder Committee.
On a volunteer basis, ESC members offer their professional expertise to review and analyze information for ISSF initiatives. Like the Scientific Advisory Committee, the ESC advises the ISSF Board of Directors on sustainability issues and efforts, including ISSF conservation measures. ESC member involvement does not imply an endorsement of ISSF policy decisions.
Seafood Supply Chain Transparency
Our 2021 Annual Report includes a feature by ESC member Dr. Tom Pickerell of the Global Tuna Alliance on efforts to verify transparency in the seafood supply chain.
