Booking Holdings has cut operational emissions 85% since 2019 and secured SBTi-validated net-zero targets by 2040. But the company ignores its massive indirect footprint—facilitating 1 billion+ annual room nights—excluding guest travel emissions from Scope 3. Regulatory action forced termination of its greenwashing 'Travel Sustainable' programme in 2024, and biodiversity and water risks remain entirely unmanaged.
