News Summary
A new report by the World Economic Forum and Boston Consulting Group warns that climate-driven health impacts could cause over $1.5 trillion in lost output over the next 25 years. The findings indicate significant productivity losses across sectors including food and agriculture, built environment, and health care, while also emphasizing the need for proactive adaptation strategies to mitigate future economic burdens.
Belém
New global report warns that climate-driven health impacts could cost the global economy more than $1.5 trillion in lost output over the next 25 years. The report, prepared by the World Economic Forum with Boston Consulting Group (BCG), finds that workforce illness linked to climate change will cut productivity across multiple sectors and that the estimate covers only a subset of affected industries, suggesting the full economic toll could be larger.
Most important findings
The report estimates that climate-driven health impacts may lead to over $1.5 trillion in lost output from certain health-related illnesses over the next 25 years. This figure only includes losses in three sectors—food and agriculture, the built environment, and health and health care—meaning additional sectors could face further productivity losses not captured in the total.
The report is titled “Building Economic Resilience to the Health Impacts of Climate Change.” It models the economic cost of lost productivity arising from seven major health risks exacerbated by climate change and covers the period between 2025 and 2050.
Sector-level impacts and breakdown
- Food and agriculture: Losses due to climate-health impacts could total $740 billion, with significant implications for global food security.
- Built environment: Projected productivity losses total $570 billion as rising heat, infrastructure stress, and disease affect workers and operations.
- Health and health care: The sector could lose $200 billion in productivity from climate-related workforce illness, while increased disease rates may heighten demand pressures on services.
Why the costs could be higher
The $1.5 trillion estimate only accounts for losses in the food and agriculture, built environment, health and health care sectors, suggesting that the total economic burden could be greater. The analysis relies on health data drawn from scientific literature and economic cost data from the International Labour Organization and World Bank; gaps in data and effects on other industries mean the real cost could extend beyond the modeled estimate.
Business risks and adaptation priorities
The study highlights that climate change is accelerating health risks such as extreme heat and infectious diseases, making adaptation a crucial business priority. Companies are advised to protect worker health and build operational resilience to avoid higher adaptation costs later. Delays in integrating health-focused resilience strategies into business practices will increase risks to human health and productivity and raise future adaptation costs.
Investing early in adaptation could also create commercial opportunities. Examples of potential innovation include climate-resilient crops, heat-stable medications, cooling technologies for workers, and novel insurance models for climate-health protections. The insurance industry is expected to see a significant rise in climate-health claims, presenting both cost pressures and opportunities for new products.
Data, policy and finance needs
The report calls for coordinated global efforts to build health resilience. That requires supportive policies, improved climate-health data systems, and innovative financing solutions to support employers, health systems, and communities in adapting to evolving risks.
Timing and context
The findings of the report were released in anticipation of the World Economic Forum’s Sustainable Development Impact Meetings and the upcoming COP30 climate conference in Belém, Brazil. These meetings, taking place from September 22 to 26, 2025, will focus on sustainable development and health adaptation strategies.
By quantifying sectoral productivity losses and naming adaptation pathways, the report frames both the risks to business continuity and the possible economic opportunities from early action on climate-related health threats.
