Galey presented document REC-14-10. He said the same system showed 85% NOx conversion on the London bus cycle but only 47% on the WHTC. Himmen added that the conversion is determined by the moment when urea can be injected. May noted that this was on the cold-WHTC and asked what the conversion would be on the weighted WHTC. Galey said it would be near 60%. His concern is that BAT would not be able to meet the 60% NOx conversion. Baarbé suggested not reopening the discussion on the 60% figure.

At the side of this discussion, Martinez asked to get clarification from the UNECE secretariat on the applicability of the REC regulation in the CPs.
