Economic Denial: A New Threat to Climate Action, Warns COP30 President

As the world turns its attention to the forthcoming COP30 climate summit in Belém, Brazil, André Corrêa do Lago, Brazil’s ambassador for climate change and president of COP30, has issued a stark warning: while traditional climate denial is waning, a more insidious form of resistance is rising—“economic denial.”

Unlike climate denial, which disputes the science of global warming, economic denial challenges the feasibility and benefits of climate action. Corrêa do Lago argues that this new opposition, rooted in skepticism about the economic viability of climate solutions, could severely hinder global efforts to address the climate crisis.

The Shift from Scientific to Economic Resistance

Corrêa do Lago observes that the global consensus on climate science has grown significantly in recent years. The physical reality of climate change is no longer widely disputed. However, resistance has shifted toward questioning the economic rationale for action—focusing on the perceived costs, disruptions, and competitiveness concerns of climate policies.

This kind of denial, often promoted by populist leaders and certain business sectors, questions whether shifting to a low-carbon economy will actually result in positive outcomes. Critics claim that decarbonization efforts will harm industries, jobs, and economic growth.

Corrêa do Lago points to past administrations, such as that of former U.S. President Donald Trump, as examples of how populist politics can fuel public doubt about climate-friendly economic measures. Such skepticism often results in the rollback of important environmental policies and delays in investment toward green infrastructure.

The Economic Case for Climate Action

Despite this backlash, a large body of research supports the economic benefits of tackling climate change. Influential reports, including the Stern Review and findings from institutions like the OECD and UNDP, have consistently demonstrated that the costs of inaction far outweigh the investments required for sustainable development.

Nevertheless, Corrêa do Lago notes that many governments and companies still fail to factor climate risks into their economic planning. This omission, he warns, leaves countries unprepared for the long-term consequences of climate inaction and undermines the credibility of climate commitments.

To counter economic denial, Corrêa do Lago calls on economists, financial institutions, and development agencies to better communicate the tangible gains of climate action. He believes it’s essential to show that green transitions can create jobs, boost innovation, and lead to more resilient economies.

COP30: A Platform for Adaptation and Collective Action

The upcoming COP30 summit in Brazil is expected to play a vital role in strengthening global climate governance. One of its key focuses will be on adaptation—ensuring countries not only reduce emissions but also prepare for the inevitable impacts of climate change.

Corrêa do Lago emphasizes the importance of linking climate negotiations with on-the-ground implementation. He argues that it’s time for global agreements like the Paris Accord to move beyond paper commitments and translate into structural solutions. This includes reinforcing Nationally Determined Contributions (NDCs) and encouraging tangible actions at the national and local levels.

He also highlights the pivotal role of cities in this fight. Urban areas are often at the frontline of climate impacts and are key to implementing adaptation strategies. By empowering local governments and sharing success stories, Corrêa do Lago hopes to inspire broader, more effective participation in climate solutions.

A Global “Mutirão” Against Climate Change

Corrêa do Lago invokes the Brazilian concept of a “mutirão”—a collective effort or community-driven task—to describe the global collaboration needed to overcome the climate crisis. He envisions COP30 as not just a diplomatic event, but a turning point where diverse stakeholders come together to pool knowledge, resources, and political will.

He believes that only through collective action—spanning governments, businesses, civil society, and individual citizens—can the world move toward a truly sustainable future.

Conclusion

The battle against climate change is no longer a debate about science but one about economics and political will. As COP30 approaches, André Corrêa do Lago’s warning about economic denial serves as a critical reminder that resistance to climate action is evolving. If left unchecked, this form of denial could delay the urgent transition the planet so desperately needs.

The hope now lies in coordinated, transparent, and inclusive strategies—ones that prove climate action is not just necessary for the environment, but also a path to lasting economic prosperity.
