Each year, Future 500 releases a Top 10 report of what we predict will be the most critical issues driving stakeholder engagement in the coming year. It consists of a breakdown and analysis of the key issues based on interactions with a broad range of stakeholders – funders, activists, companies and policy makers, to name a few. From politics to energy production, ocean acidification to deforestation, 2015 will continue to present a wide range of challenges that will require stakeholder attention.
