NHS Wales Emissions Surge 20% Despite Decarbonization Targets

As of November 2025, NHS Wales is facing a significant challenge in its efforts to reduce carbon emissions. According to the latest data, total emissions from the healthcare system have risen by 20% since 2018-19, despite targets to decrease them by 16%.

The NHS has attributed this increase to its suppliers, and has vowed to work closely with outside firms "to minimize environmental impact". Interestingly, emissions from areas outside the supply chain, such as buildings and transport, have decreased by nearly a quarter over the same period, which the NHS has hailed as "significant progress".

However, the overall picture remains concerning. NHS Wales has a duty, under Welsh government criteria, to reach net zero by 2050. But a recent report by the Climate Change Committee found that Wales was falling behind on the actions needed to fight climate change.
