The secretary presented working paper HDH-12-06. The secretary had proposed at the 11th meeting to submit the final report at the 67th GRPE in January 2014, which consequently would delay GRPE adoption to June 2014. The updated roadmap, which is shown on page 7 and had been agreed at the 11th HDH meeting, was confirmed by the larger group of this meeting, and will be reported to GRPE 65 for approval.

The secretary suggested to hold the 15th HDH meeting during the week of 21 October 2013. The proposal was agreed. The secretary will ask the ICCT for confirmation.
