IHG's total emissions have risen 7.2% since 2019 despite intensity improvements, and the company admits it will miss its 2030 SBTi target. A 46% absolute reduction is now unachievable; target review underway. Supply chain Scope 3 coverage is incomplete, renewable energy penetration across the 6,700-hotel estate remains marginal, and absolute waste and water consumption are not declining.
