McKinsey reports 62% Scope 1&2 reductions and 100% renewable electricity, but its dominant emissions (Scope 3 business travel) are tracked only per-employee, not absolute. Most damaging: the firm refuses to disclose client emissions—orders of magnitude larger than its own—while investigative journalism and litigation expose it advising fossil fuel clients on climate delay strategies and promoting carbon schemes that undermine net-zero goals.
