All Magnificent Seven companies fall short of a 1.5°C climate pathway, Morningstar says

All seven Magnificent Seven companies remain misaligned with a 1.5°C climate pathway, according to Morningstar Sustainalytics' Low Carbon Transition Ratings published Oct. 14. Nvidia shows the highest implied temperature alignment at 2.5°C, Meta follows at 2.3°C, and Tesla sits at 1.8°C despite carrying the group's highest climate management score.

Morningstar ties the exposure to the AI buildout: Alphabet, Amazon, Meta and Microsoft face heightened climate transition risk as operators of hyperscale data centers and AI infrastructure. The compute behind large-scale AI models means more data centers, higher electricity demand and higher greenhouse gas emissions; absolute emissions across the group have been rising.

Morningstar flags water scarcity, data privacy, cybersecurity, labor management and business ethics as emerging concerns. Reported Scope 2 emissions — indirect emissions from purchased energy — can vary significantly depending on whether a firm uses market-based or location-based accounting, Morningstar notes.

Morningstar says climate management practices across the group are generally well-developed.
