Climate Change & Environmental Speakers

Climate change and environmental speakers play a crucial role in making people aware of the damage that is being done to our planet. Since 1850, global temperatures have risen by about 2°F, driving extreme weather, habitat loss and biodiversity decline. The World Health Organization warns that climate-related health damage could cost $2-4 billion each year by 2030. These speakers use powerful data, real-world examples and compelling stories to highlight the urgency of the crisis.

By showing the visible and hidden impacts on our air, oceans, wildlife and communities, climate change and environment speakers inspire audiences to take responsibility, adopt sustainable choices and work collectively to protect planet Earth.

Climate change refers to long-term shifts in global temperatures and weather patterns, largely driven by human activities such as burning fossil fuels and deforestation. It matters because these changes are already affecting ecosystems, economies and human health on a global scale. According to the World Health Organization, climate change is expected to cause around 250,000 additional deaths per year between 2030 and 2050, due to factors such as heat stress, malnutrition and disease. This highlights the growing urgency of addressing climate change, as its impacts extend far beyond the environment to directly affect human wellbeing and global stability.

Climate change and environment speakers cover a wide range of topics focused on sustainability, environmental impact and future-focused business strategies. Common areas include climate science, carbon reduction and net zero goals, as well as renewable energy, circular economy and sustainable innovation. Many also explore ESG (environmental, social and governance) strategies, corporate responsibility and how organisations can reduce their environmental footprint. In addition, speakers often address climate risk, policy and the long-term implications of environmental change, providing practical insights that help businesses adapt, stay compliant and contribute to a more sustainable future.

The leading climate change and environment speakers include Nigel Topping, Christiana Figueres, Tom Rivett-Carnac, Alexandra Palt, Lucas Joppa, Chris Hines, Liz Bonnin, Kate Brandt, David Howell and Chadden Hunter. These experts are recognised for combining scientific knowledge, policy expertise and real-world business insight to help organisations better understand climate change, sustainability, net zero strategy and environmental innovation.

Industry-leading platforms such as The Sustainability Speakers Agency bring together a global roster of these experts, connecting organisations with thought leaders who are actively shaping the future of sustainability and environmental progress
