Manchester Met has cut Scope 1+2 emissions 65% since 2005 and publishes audited sustainability data annually. The Ryebank Fields controversy — selling a 10-acre rewilded site to developers while promoting biodiversity campaigns — exposes a material gap between stated values and land-use decisions. Scope 3 reduction trajectory remains weak with only one year of verified data.
