T-Mobile leads US telecom on emissions reductions and renewable energy, with SBTi-validated targets and 33% absolute cuts since 2020. Major weaknesses: no biodiversity policy, minimal water disclosure, and weak nature-risk assessment despite infrastructure footprint. Governance lacks executive pay-for-sustainability linkage.
Same formula for every company. No curve. No private weighting.
