Understanding human behavior at the deepest levels is no longer an option. It’s an imperative.

When it comes to meeting our most urgent ecological challenges, our engagement and communications efforts require a fundamental fluency in how people not only think, but feel about our changing world. The greatest barrier facing engagement is not more education or awareness-raising. It’s how people may find it hard to process such challenging information, such as climate change threats, water and food security, threats to wildlife conservation, or our relationship with energy.

Renee Lertzman knows how to turn our aspirations for a better world into actions that make a difference. She works with leaders in business, government, NGOs, and academia to develop innovative research, insightful strategies, and transformative learning programs to engage stakeholders in responding to the most profound challenges of our time. Central to this is applying insights from psychosocial research, neurosciences and social sciences to how we can be more effective and impactful in our communications. Often this involves rethinking our assumptions when it comes to behavior change and the psychology of our current environmental challenges. Learn more about Renee…
