Honeywell publishes sustainability reports but hides absolute emissions figures behind intensity metrics, masking whether actual pollution is declining. A systemic pattern of Superfund contamination across multiple states, $446M+ in environmental penalties, and active lobbying against US climate policy through industry groups directly contradict its carbon neutrality messaging.
