20. Mr. Rijnders has mentioned previously the possibility of updating R.115. Now that there will be new dual-fuel regulations added the scope of R.115 may need to be specified as pertaining to light duty vehicles while heavy duty applications in R.115 might have to be removed (in light of a new dual-fuel regulation that would incorporate heavy duty vehicles). It may make better sense to postpone the re-evaluation of R.115 until after the new retrofit document has been prepared.
21. There is general agreement by the group that there are other priorities for the various members and it is not so urgent that this should be tackled now.
