Fire at COP30 venue in Belem, Brazil
United Nations climate talks at the COP30 summit in Belem, Brazil, were evacuated after a pavilion fire disrupted negotiations on Thursday, with 13 people treated for smoke inhalation, according to organisers.
Media reports from AP News, The Guardian and Sky News stated that the fire broke out in the pavilion area used for side events and exhibits.
Organisers said the blaze was brought under control in about six minutes.
The affected structures were described as reinforced canvas or fabric pavilions with three walls and a floor.
Brazil’s Tourism Minister Celso Sabino said the incident started near the China Pavilion, one of several national and thematic spaces in the zone.
Footage reported by AP News showed flames running along a wall close to pavilions for African countries and the Climate Live Entertainment + Culture Pavilion.
Para state Governor Helder Barbalho told local outlet G1 that early indications pointed to a generator failure or a short circuit in a booth.
According to The Guardian, the local fire department also reported that an electrical device, probably a microwave, was being examined as a possible source.
Evacuation, injuries and immediate fire response
Organisers said the fire department and UN security staff responded quickly to the incident in the blue zone of the venue.
They confirmed that people were evacuated safely from the site.
Thirteen individuals were treated on site for smoke inhalation and received medical support.
Officials said their condition continued to be monitored after the fire was extinguished.
AP News reported that the entire conference site was then closed for around seven hours.
When the venue reopened, attendees were allowed back into areas away from the damaged pavilions to collect belongings or resume meetings.
Security staff remained in place behind metal barricades to prevent access to the affected pavilion zone.
Curtains were used to shield the burned area from view as people re-entered the site.
Volunteer Gabi Andrade, who is from Belem and had been working on accreditations, described being guided out of the venue while seeing black smoke.
Gabi Andrade, a volunteer from Belem, said: “It’s so sad for us,
“We all worked so hard.”
Conference timetable and negotiations hit by venue closure
Reports stated that the incident came during the final scheduled days of COP30 negotiations.
The Guardian said talks had already missed a self-imposed deadline on Wednesday to complete an initial package of decisions.
According to the same report, the COP30 presidency had been preparing a fresh draft of the “mutirão” decision when the fire occurred.
That decision was expected to include a potential commitment to develop a roadmap to transition away from fossil fuels.
Planned meetings between the presidency and negotiating groups, including the Alliance of Small Island States, were cancelled or delayed after the evacuation.
An internal European Union ministerial coordination meeting and a later session with the presidency were also placed in doubt.
Sky News reported that delegates had travelled from many regions of the world to participate in in-person negotiations on climate action.
The outlet noted that the disruption added further difficulty to discussions already focused on how to close the gap between current warming trajectories and previously agreed temperature goals.
Construction conditions and cause of the fire under review
AP News reported that much of the summit site in Belem had been under construction shortly before the talks opened.
The venue included exposed beams, open plywood floors and metal mesh corridors around the convention centre.
Workers in hard hats were described as completing unfinished pavilions during a pre-summit event as leaders delivered speeches nearby.
The pavilion area where the fire occurred consisted of temporary structures erected for country and thematic exhibits.
Officials indicated that the precise cause of the fire remained under investigation.
Local authorities were considering both a possible generator failure and a short circuit involving equipment at a booth.
The Guardian reported that the fire department believed an electrical device, likely a microwave, may have been involved.
No fatalities were reported and authorities confirmed that the fire was contained to the pavilion zone.
Operational implications of the COP30 pavilion fire
The COP30 incident highlights the fire risks associated with temporary pavilions, extensive electrical equipment and ongoing construction work at major international events.
Emergency and disaster response managers involved in large conference operations may review how evacuation procedures function when a single zone fire requires full-site clearance.
Fire and rescue chiefs and senior officers will note that the blaze was controlled within minutes yet still led to hours of disruption for negotiations.
This dynamic underlines the need to balance rapid suppression, smoke control and safe re-entry protocols where political or diplomatic timetables are time-sensitive.
Facility managers for convention centres and exhibition complexes can draw lessons from the way unfinished structures, exposed materials and temporary generators interacted with high delegate density.
Standards and certification bodies may consider how guidance on electrical devices, temporary structures and emergency planning applies to global summits where many national pavilions operate within a shared envelope.
Architects and building services engineers working on modular or temporary venues may also review layout, compartmentation and access routes in light of an incident that originated in one pavilion yet led to whole-site impacts.
