A new report highlights the urgent need for healthcare systems to adapt to the threats posed by climate change. The report, released by McKinsey, states that current solutions to help healthcare meet these challenges are “immature” and that scaling sustainability solutions is “critical for protecting vulnerable populations.
The 2023 UN Climate Change Conference (COP28) marked a shift in focus towards the connection between climate change and human health. The World Health Organisation has designated climate change as “the greatest threat to global health in the 21st century,” underscoring the pressing need to protect vulnerable populations such as women, children, the elderly, low-income earners, Indigenous and migrant groups, and those in lower-income countries.
The report suggests that health sectors should consider scaling existing programs to manage the risks exacerbated by climate change. For example, increasing vaccination efforts against cholera in areas with heightened flood risk is one viable approach. However, the report notes a significant financial barrier, estimating that the annual shortfall of investment needed to adapt health systems is between £21-£45 billion.
Adapting healthcare to climate challenges
To create change on this scale, new policy and financing models will be necessary. The report proposes several potential solutions, such as prioritizing areas for impactful and equitable innovations and deploying promising solutions drawn from the Health Innovation Exchange’s (HIEx) global call for climate and health innovations.
Climate risks can affect a wide range of health conditions, both directly and indirectly, impacting health systems’ ability to provide care due to effects on infrastructure, value chains, and health workers. The risks and outcomes will vary widely by locality, depending on local exposure and vulnerability factors. The report also notes that 120 countries endorsed the COP28 Declaration on Climate and Health, with £1bn in funding committed to addressing the issue.
The topic is expected to remain prominent at the 2024 G20 summit in Brazil and subsequent COP events in Azerbaijan and Brazil, where discussions will focus on climate-finance goals and nationally determined contributions.
