Security staff had to step in to protect Shell Chief Executive Wael Sawan and the company’s board of directors on Tuesday, as climate protesters attempted to storm the stage of a shareholder meeting that took place in London, per Reuters.

The protesters reportedly managed to prevent Shell Chairman Andrew Mackenzie from being able to start the energy company’s yearly general shareholder meeting by an hour. The report noted that the activists were singing and shouting, which resulted in them having to be escorted out by security staff. However, the outrageous behavior is almost certainly going to do little in the way of changing the energy company’s way of doing business.
