With financial support from The European Climate Initiative (EUKI), HCWH Europe launched a pilot project to support six European hospitals in measuring their carbon footprint, including greenhouse gas (GHG) emissions from the use of anaesthetic gases. During the project, (which ran until March 2018), HCWH Europe worked with hospitals from France, Germany, Poland, Portugal, Spain, and Sweden to measure emissions and share data.In order for the EU to meet its 2030 climate and energy package targets, countries must set national goals for different economic sectors. While healthcare makes up an estimated 5% of European GHG emissions, very few health systems have measured their carbon footprint or set emission reduction targets.To be able to set national and European targets for the healthcare sector, the sector must first track and measure its emissions. Very little data about...
