Some oil and gas giants are being pushed by shareholders to adopt more climate friendly strategies.

An environmental law charity is suing the directors of a global oil company, arguing their climate strategy is not adequate to meet current targets, supported by other shareholders. Elsewhere, a group of investors in another fossil fuel giant, recently unseated multiple board members in an effort to force a change of direction.

How effective is this form of activism?
