In 2026, environmental issues have become a strategic challenge for all organizations, whether it’s anticipating regulatory changes, managing their transition, or meeting the growing expectations of stakeholders. Given the complexity of these challenges, decision-makers need concrete feedback and reliable analysis to guide their choices, mobilize their teams, and anchor action on the ground. To support this movement, we have selected ten speakers who can offer both practical insights and inspiring perspectives on environmental transformation. Their voices help open up new perspectives and effectively equip those who are committed to making a difference.
