The conference was originally scheduled to be held in October 2020, but was delayed due to the
COVID-19 pandemic. It was rescheduled to be held in April 2022 in
Kunming, China, but was postponed again, for a fourth time due to
China's zero-COVID policy, to the third quarter of 2022 according to the UN secretariat office on March 29. In May 2022, China requested Canada to assume the host responsibility. The
Canadian Minister of Environment and Climate Change Steven Guilbeault met with representatives from the
High Ambition Coalition in early June 2022 and these representatives asked Canada to host COP15. The
Prime Minister of Canada Justin Trudeau approved the proposal. In June 2022, the UN secretariat for the Convention on Biological Diversity and China's environment ministry said in separate statements that the meeting would be held in December 2022 in
Montreal, Canada, where the secretariat is based, though China would remain the president of the summit. This arrangement is consistent with previous practices of moving the meeting to a different country, such as the
2017 United Nations Climate Change Conference (
Fiji held the presidency while
Germany organized the meeting for practical purpose) and the
2019 United Nations Climate Change Conference (
Chile maintained the presidency despite the meeting being moved to
Spain due to
political instability in Chile). While the host countries of previous COPs had one to two years to organize the conference, Canada had just five months to prepare for the arrival of 18,000 delegates from 196 CBD member states, non-governmental organizations, industry groups and academia. This is the second time Montreal served as the host city for a UN Conference of Parties meeting, the first time being the
COP11 climate change conference in 2005. Montreal also played host to the negotiations for the
Montreal Protocol. ==Development==
