Sustainability in education is moving from campus pledges to measurable requirements, even as emissions sources remain stubborn. For example, transportation still drives 29% of US greenhouse gas emissions in 2022, while learning and operations decisions in schools increasingly determine whether that footprint shrinks. This post connects curriculum, buildings, waste, and software tracking through the latest dataset findings to show exactly where education is making progress and where the gaps keep widening.
