This week marked the start of the civil trial against BP over its role in the 2010 explosion at the Deepwater Horizon oil rig that killed 11 men and caused the worst spill in U.S. history. District judge Carl Barbier warned of a lengthy trial, one that could last up to three months if a deal isn’t reached earlier, and if the first three days of the trial are anything to go by, BP is in for a battery of tough questions about its safety record and procedures. As much as $17.5 billion in damages is hinged on the legal question of whether the company was “grossly negligent” in causing the deaths and the subsequent spill. Climate Desk caught up with Dominic Rushe at partner publication, the Guardian, who has been covering the trial as it unfolds.
