As the climate conference goes into its fifth day, with huge amounts still unresolved, there were reports that activists had blockaded the entrance to the centre

Some more pictures of this morning’s protests are coming through. And my colleague Oliver Milman has arrived at the scene and says Cop president Andre Correa do Lago is now talking to the protesters.

My colleague Dharna Noor has this update on the day ahead.

Negotiations at Cop30 are moving along, but it has become clear which issues will become major sticking points. Among those problems: trade, transparency regarding emissions reporting and finance, and the need for countries to regularly submit action plans (known in Cop-talk as “nationally determined contributions”) to draw down planet-heating pollution. We’re hoping to have an update on these challenges on Saturday from Brazilian officials.

Parties are also working through disagreements on finance for adaptation to the climate crisis. But Cop is not merely about politicians’ negotiations. This year, the conference has also sparked a colorful array of events held by civil society groups. “That’s where it’s really all happening,” Susana Muhamad, former environment minister for Colombia, told my colleague Jon Watts and I on Wednesday evening.
