The Asia-Pacific (APAC) region faces outsized health impacts from climate change due to its unique combination of high population density, vulnerable health systems, and frequent exposure to extreme weather events. This places immense strain on public health infrastructure and social stability. These climate-related health impacts challenge the private sector, disrupting businesses as declining health among workers, consumers, and communities drives lower productivity, supply chain disruptions, and reduced market demand.
Climate Impacts on Workers, Consumers, and Communities
Workforces are on the front lines of climate-related health risks. Nearly 75% of the labor force in APAC is now exposed to excessive heat. This leads to dehydration, heatstroke, and fatigue, especially for outdoor and factory workers. Globally, heat causes 22.85 million work injuries and 19,000 deaths annually, nearly half in APAC.
In Tamil Nadu, extreme heat and poor ventilation cause heat rashes and urinary infections among women garment workers, leading to absenteeism and production delays. For example, within just one week of May 2024, 13 women garment workers reported symptoms including rashes and increased white discharge. In Vietnam, Typhoon Yagi caused 2.3 million lost workdays, damaged 550 healthcare facilities, and exposed workers to disease, stress, and unsafe conditions. In South and Southeast Asia, farmers face rising pesticide poisoning and mental health challenges from crop failures and climate-related economic stress.
Climate shocks also disrupt logistics and supply chains, limiting consumers’ access to nutritious food, clean water, and healthcare. In 2023, Cyclone Mocha crippled supply routes across Bangladesh and Myanmar, causing widespread shortages of food and medical supplies. These disruptions not only harm public health but also reduce demand and purchasing power in affected markets.
At the community level, climate-driven displacement and infrastructure damages are undermining social and economic stability. Between 2010 and 2021, disasters triggered by climate hazards displaced over 225 million people across APAC. These events drive disease outbreaks, sanitation crises, safety risks, and local economic collapse, weakening consumers and reducing workforce availability.
Private Sector: From Risk to Responsibility
As cascading risks intensify, the private sector has both the opportunity and responsibility to act. Businesses across APAC are uniquely positioned to play a catalytic role in strengthening climate and health resilience. A growing number of companies are beginning to shift from reactive crisis response toward proactive investment in systems that protect health, livelihoods, and business continuity—demonstrating how targeted innovation can reduce health risks while building long-term economic resilience.
In India, ITC Agribusiness supports farmers via ITCMAARS, using AI, big data, and local weather forecasts to guide crop planning, irrigation, and nutrient management. The platform promotes crop diversification and regenerative practices, boosting yields and income while reducing health risks like pesticide exposure and heat stress.
In Nepal, Microsoft has partnered with GSK and the Centre for Health and Disease Studies to deploy Microsoft Premonition, an advanced disease surveillance and early-warning platform. Combining AI-powered predictive analytics, robotics, and autonomous “biological weather stations,” the system monitors disease-carrying organisms and forecasts outbreaks of vector-borne illnesses such as malaria and dengue—both of which are exacerbated by climate change. This enables public health authorities to respond proactively, reducing the risk of large-scale health crises.
In Indonesia, Nestlé’s Nespresso brand operates the Café Seguro program, a weather-index crop insurance initiative designed for smallholder coffee farmers. By using real-time satellite-based climate data to trigger automatic payouts during extreme weather events like droughts or heavy rainfall, the program allows farmers to recover faster and protects them from the psychological and financial stress of repeated climate shocks.
Scaling Resilience Through Collective Action
Many companies across APAC have already recognised the opportunity to better protect the health of their employees, consumers and communities where they operate, and their pioneering initiatives demonstrate what is possible. The path forward requires moving from pockets of innovation to mainstream adoption—embedding climate-health adaptation into core business strategies. In sectors like agriculture and manufacturing, integrating climate risk assessments into labor policies and leveraging digital tools for real-time risk insights can help mitigate both economic and health impacts.
Resilient supply chains are another imperative. Consumer goods, healthcare, and life sciences companies can lead by developing climate-resilient products while strengthening logistics networks and diversifying suppliers to withstand extreme events. Financial institutions can expand inclusive insurance and credit products to protect vulnerable populations and reduce systemic recovery costs. Meanwhile, technology and energy firms can accelerate the deployment of predictive tools, early-warning systems, and emergency-response platforms to safeguard both people and infrastructure.
Collaboration will be critical to scaling these efforts, given that climate–health risks are too complex for any one sector to address alone. Leading companies are increasingly partnering beyond their value chains—working with governments, civil society, and industry peers to develop shared solutions. In agriculture, consumer goods and fashion brands are investing in regenerative practices and climate-smart technologies to boost farmer resilience and secure supply chains, while in healthcare, life sciences and MedTech companies support climate-ready clinics and physician training—demonstrating that collective action can drive long-term, scalable impact.
Leading the Path to Resilience
The private sector in APAC stands at a crossroads. The scale of the challenge is undeniable, but so too is the opportunity to lead. By embedding health outcomes into climate strategies and investing in systemic resilience, businesses can protect their workforce, secure their supply chains, and create shared value for consumers and the communities they depend on. The call to action is urgent and unambiguous: act decisively, invest with foresight, and forge partnerships that enable a future where climate resilience and health equity advance together.
