Environmental campaigners Extinction Rebellion will shut down their two remaining central London protest sites on Thursday, the group said in a statement.
Over 1,000 people have been arrested during the protests, which have lasted over a week, as part of the group's campaign of non-violent civil disobedience with the aim of stopping what it calls a global climate crisis.
"We know we have disrupted your lives. We do not do this lightly. We only do this because this is an emergency," the group said in a statement on Wednesday.
"Around the planet, a long-awaited and much-needed conversation has begun."
