Environmental advocates and some scientific experts are raising serious concerns about Daikin’s decision to employ a new PFAS chemical that breaks down into trifluoroacetic acid, a pollutant that remains indefinitely in ecosystems and has potential reproductive toxicity. They warn that approving such chemicals risks perpetuating the accumulation of hazardous substances in the environment.
TFA's status as a "forever pollutant" means it does not degrade further and can contaminate waterways, potentially entering food chains and affecting biodiversity and human health. Critics argue that its possible reproductive effects heighten the stakes, especially as scientific studies continue to uncover links between PFAS exposure and various health problems.
This use could undermine global and European efforts to phase out PFAS chemicals, which are increasingly regulated due to their broad environmental persistence and toxicity. Allowing new PFAS production sets a precedent that may delay comprehensive restrictions and weaken precautionary principles designed to protect communities and nature.
Opponents call for stricter regulatory scrutiny, transparency, and the acceleration of safer alternatives development. They caution that depending on industries to self-assess risks and comply with existing standards is insufficient given the long-term consequences and past underestimations of PFAS hazards.
