The new European Union-mandated refrigerant HFO-1234yf increases safety risks, but not enough to pose an outright danger to motorists, according to Reuters.

The news service cites an analysis by Germany's Federal Motor Transport Authority, which also calls for more tests to definitively rule out any safety problems.

In January the EU began requiring new vehicles sold in the region to use the greener 1234yf refrigerant instead of R134a, the former industry standard material. Daimler AG refused, citing its own tests that indicate the new fluid could catch fire in a crash and create poisonous fumes.

A multitude of previous evaluations including several that describe Daimler's test as unrealistic have declared 1234yf safe.

The European Commission has given the German government until Aug. 20 to explain why it has allowed Daimler to ignore the refrigerant ban.
