Luxembourg has taken a clear stance against Solar Radiation Management (SRM). This technique aims to reflect some sunlight to combat climate change, but many experts view it as a risky manipulation of our natural systems. The government, in a recent report, stated they do not consider SRM a viable solution for climate change.
Currently, no SRM research projects are underway in Luxembourg. The Ministry of the Environment argues that these methods aren’t necessary for meeting the Paris Agreement’s climate goals. Studies from the Intergovernmental Panel on Climate Change (IPCC) underline this position, highlighting the potential risks of altering weather patterns, increased UV radiation, and the lack of impact on carbon dioxide levels. They also warn that relying on SRM could cause abrupt climate changes if these methods were suddenly halted.
Instead of SRM, Luxembourg is prioritizing Carbon Dioxide Removal (CDR). Unlike geoengineering, CDR focuses on reducing carbon emissions directly by capturing carbon from the atmosphere and implementing biological processes that enhance biodiversity and water protection. This approach aligns with a broader strategy to achieve climate neutrality by 2050.
Two notable CDR projects are currently in progress with backing from European funding. The Pyrah2 project aims at negative emissions in partnership with Goodyear SA and has received €655,376. Another project, BioPhenom, is researching biochar and is supported by €487,810.
These initiatives fall under Horizon Europe, the EU’s research and innovation funding program for 2021-2027. The Luxembourg government participates in discussions about funding priorities but acknowledges its influence is limited. The country is dedicated to strengthening CDR methods to ensure a sustainable future.
While Luxembourg is open to exploring SRM governance, it emphasizes the need for strict regulations and extensive environmental assessments. As the global conversation about climate solutions evolves, Luxembourg remains cautious, prioritizing proven methods that safeguard both the climate and public health.
