Workforce Heat Resilience: An Actionable Framework to Close the Execution Gap

Extreme heat is a growing structural risk to global economic stability, affecting over 2.4 billion workers and potentially causing $2.4 trillion in productivity losses by 2030. Despite this, a significant 'execution gap' exists: while over 80% of surveyed leaders view heat as an urgent risk, only 28% have implemented interventions. The report introduces the Workforce Heat Resilience Roadmap, a seven-step process to move from initial risk assessment and business case development to the piloting and scaling of engineering, administrative, and personal protective equipment (PPE) solutions. Case studies from companies like Bayer, Mahindra Group, and JINGDONG Logistics demonstrate that proactive measures—such as hydration protocols, cooling infrastructure, and AI-enabled warning systems—can reduce workplace incidents and improve ROI.

• Extreme heat poses a severe global threat to worker health and economic output, with over 2.4 billion workers exposed to excessive heat, resulting in at least 22 million injuries and 18,000 deaths annually. Without significant mitigation, the International Labour Organization (ILO) projects a global GDP reduction of $2.4 trillion by 2030.
• There is a substantial 'execution gap' in corporate responses to heat risk; although 82% of surveyed senior leaders agree that extreme heat is an urgent and major risk, approximately 50% have not started systematic assessments and only 28% have implemented or scaled interventions.
• Heat-driven work-time losses can significantly impact corporate earnings, with illustrative models suggesting these losses may amount to roughly 5-7% of earnings by 2027 across various company sizes and geographies.
• The report defines extreme heat as a wet-bulb globe temperature (WBGT) of 25°C or higher, the threshold where work capacity typically begins to decline for physically demanding labour.
• Heat impacts are not limited to direct employees but cascade across the value chain: upstream, they cause volatility in supply quality and cost; downstream, they shift demand patterns, such as the record 14 million air conditioner units sold in India in 2024.
• Effective heat resilience requires a combination of interventions based on the hierarchy of hazard controls: engineering controls (e.g., cooling centres), administrative controls (e.g., work-rest cycles), and personal protective equipment (e.g., cooling vests).
• Acclimatization—gradually increasing heat exposure over 10-14 days—is a critical but underused intervention, as 80% of worker heat-related illnesses occur within the first four days of a job.
• Vulnerable groups, particularly women in the informal economy, face higher risks; research by SEWA and Harvard found that indoor heat indices in low-income homes can be up to 10°C higher than outdoor readings, affecting sleep and recovery.
• Proactive heat management can yield high financial returns; for example, a food and agriculture company in Latin America saw a 60% return on investment from its heat stress management programme.
• Scaling heat resilience requires integrating protocols into the broader operating model, including standard operating procedures (SOPs), governance, and incentive structures, as demonstrated by Ingenio San Antonio's 94% reduction in hospital-treated acute kidney injury.
