The multilateral assessment (MA) process is part of the international assessment and review (IAR) process for developed country Parties. The IAR process is conducted under the Subsidiary Body for Implementation (SBI) and aims to promote the comparability of efforts among all developed country Parties with regard to their quantified economy-wide emission limitation and reduction targets.

The IAR process comprises two steps: a technical review of the national reports of each developed country, followed by the MA of the progress towards achieving the economy-wide target by developed country Parties.

The MA process entails three stages:

• the preparation for the MA before the SBI working group session - encompassing a three-month "questions and answers" period; more
• the international assessment during the SBI working group session; more
• and the completion of the Party record after the SBI working group session. more

The second round of the IAR started in January 2016, with the submission of the second biennial reports from Annex I Parties and the technical review of these reports by international expert review teams. 24 Annex I Parties have been multilaterally assessed during the MA session in Marrakech, Morocco, SBI45, while 17 Annex I Parties were multilaterally assessed during SBI 46 in Bonn, Germany (May 2017). The MA of Belarus has been postponed until further notice.

	1 to 28 February 2017: submission of questions by any Party to the 18 Parties under MA - using the MA portal;
