These are not mutually exclusive strategies. Back during the 1980s, activists in the US tried to get the Reagan administration to pass sanctions against apartheid South Africa. While Reagan stalled, they successfully got individual companies to stop doing business with South Africa. None of these individual actions stopped white-only rule in South Africa. Nor did anyone involved in the process think it would. But it was part of a worldwide movement that did ultimately lead to US sanctions and the end of apartheid. In fact, one of the things that encourages government action is seeing that the change being suggested has become mainstream. Businesses boycotting the oil and gas industries could be an effective part of that.
