11. The Chair of the IWG on Measurement Uncertainties (MU) under GRBP introduced WP.29-187-06. The representative from the EC reminded that in most emission legislation, measurement uncertainties were already taken into account in setting the emission limits. The Chair of the IWG on MU gave the example of UN Regulation No. 117 where uncertainty was greatly underestimated that might lead to revised way to set-up limits in the future. The Chair agreed measurement uncertainties were already included in emissions legislation and the definitions of emission limits. GRPE agreed to look at future progress of the IWG on MU and the inclusion of the uncertainty table in other UN Regulation before committing to include the proposed uncertainty table into the relevant GRPE legislation.
