At the 9th meeting of the Conference of the Parties to the Convention on Biological Diversity serving as the meeting of the Parties to the Cartagena Protocol on Biosafety, the Parties decided, inter alia, to consider at the 10^th meeting (due to take place in October 2020 in China) whether additional guidance materials on risk assessment are needed for (a) living modified organisms containing engineered gene drives and (b) living modified fish, and to establish an ad hoc technical expert group (AHTEG) on risk assessment. The AHTEG has now been established and it will meet online from 31 March to 3 April 2020. Documents for the meeting are available at https://www.cbd.int/meetings/CP-RARM-AHTEG-2020-01.
