Text reading "Healthcare systems are essential to protecting people from the health impacts of climate change, yet the sector remains a significant source of greenhouse gas emissions and air pollution. 2026 Global Report of the Lancet Countdown."

Text reading "Global healthcare-related greenhouse gas emissions have increased by 26% since 2016. Yet, progress is underway. Since 2016, healthcare emissions have decreased in 41 countries, with over half achieving reductions through more efficient healthcare operations and decarbonised energy systems and supply chains.

Building low-carbon, climate-resilient health systems is critical to protecting health while reducing the sector's environmental impact. Find out more at lancetcountdown.org/2026-report/

🌾 The 2026 Global Report of the Lancet Countdown highlights the growing threat that climate change poses to food production and food security.

Climate change is placing growing pressure on food production: Rising sea surface temperatures and higher ocean CO2 threaten marine food productivity, putting the food security of coastal communities at risk. More frequent heatwaves and extreme droughts led to 127.9 million additional people experiencing moderate or severe food insecurity in 2024 compared to 1981-2010.

Growing water extremes are also creating new challenges for food security. Since 2003, 43% of land experienced long-term decline in water storage while another 37% has experienced a long-term increase. Together these hydrological extremes affect more than 80% of global land area, threatening crops, food supplies and sanitation (2026 Lancet Countdown).

Protecting food security and health requires more resilient food systems, secure food supplies and more sustainable agricultural practices. Find out more at lancetcountdown.org/2026-report/
