No. 2023-017

Dear Madam/Sir,

In decision 15/27, the Conference of the Parties (COP) to the Convention on Biological Diversity requested the Executive Secretary to organize a peer-review process on annexes I to VI to this decision, which contains draft guidance, advice and a compilation of information on various matters related to invasive alien species. The COP also requested the Secretariat to make the outcomes of the peer review available for consideration by the Subsidiary Body on Scientific, Technical and Technological Advice, with a view to making recommendations to the COP at its sixteenth meeting (paragraph 2).

Decision 15/27 contains the following annexes:
(I)     Draft methods for cost-benefit and cost-effectiveness analysis which best apply to the management of invasive alien species;
(II)    Draft methods, tools and measures for the identification and minimization of additional risks associated with cross-border E-Commerce in live organisms and the impacts thereof;
(III)   Draft methods, tools and strategies for the management of invasive alien species as it relates to prevention of potential risks arising from climate change and associated natural disasters and land-use change,
(IV)    Draft risk analysis on the potential consequences of the introduction of invasive alien species on social, economic and cultural values,
(V)     Draft use of existing databases on invasive alien species and their impacts, to support risk communication,
(VI)    Draft additional advice and technical guidance on invasive alien species management.

The peer-review process will contribute to identify whether there are any important gaps of information or factual errors in the content of the annexes. At the same time, the peer review will provide an opportunity to consider the relevance of the annexes in the context of the Kunming-Montreal Global Biodiversity Framework and, in particular, towards the achievement of target 6.

The annexes are available for peer review at alongside the template for peer-review comments. Please note that only comments submitted using this template will be considered.
