Nine activists attached themselves to the revolving doors and windows of the central London office yesterday afternoon local time, the BBC reported.
Melbourne-based BHP spokeswomen confirmed with International Longwall News that a protest had taken place but would not comment further on the demonstration.
The protest was against the use of coal as an energy source.
One protester, Inez Carpentier, said mining giants such as BHP were undermining action on climate change.
“Expansion of the coal industry is unacceptable in the face of impending climate chaos,” he said.
Last week the same protesters took part in a week-long demonstration against German power company E.On’s plans to build a new coal-fired power station in Kent.
The Kent Climate Camp attracted 1500 people.
