AT&T has strong operational emissions reduction (52% absolute cut since 2015) and comprehensive Scope 1/2 reporting with third-party assurance. Weaknesses are clear: no Scope 3 absolute reduction target, no RE100 commitment despite renewable energy claims, minimal nature/biodiversity disclosure, and mixed climate lobbying including opposition to Texas environmental regulations.
