Tanzania has established itself as a major participant at the COP30 climate summit in Belém, Brazil, by sending one of the world's largest national delegations.
According to provisional figures from the United Nations Framework Convention on Climate Change (UNFCCC), Tanzania registered 465 delegates for the summit, ranking 9th globally in terms of delegation size.
The Tanzanian delegation includes government officials, public institutions, the private sector, and civil society organizations.
A Global Gathering
The summit in Belém, which has seen more than 56,000 delegates sign up, is provisionally one of the largest in COP history. A total of 193 countries, plus the European Union, have registered a delegation.
While the host country, Brazil, naturally leads with 3,805 delegates, Tanzania is among the nations demonstrating a substantial presence. The countries with the most delegates registered, in order, are:
Notable Absences and Context
The provisional delegate total of 56,118 places COP30 as the second-largest in history, behind only COP28 in Dubai. The large turnout occurred despite reports of accommodation shortages and "sky-high" costs in the host city, which led Brazil to offer free cabins on cruise ships to delegations from low-income nations.
Meanwhile, the US—the world's largest historical emitter—made headlines by not sending a delegation of "high-level officials." This followed newly inaugurated US President Donald Trump signing a letter earlier this year to trigger a second US withdrawal from the Paris Agreement. The US is joined by Afghanistan, Myanmar, and San Marino as the only countries without registered delegations.
