Hammerson reports falling, BDO-assured operational emissions and has a wind PPA and on-site solar, but its Scope 3 leaves out purchased goods, development materials and most occupier energy, and occupier data coverage fell to 18%. Its net-zero target covers Scope 1 and 2 only and is not SBTi-validated. No fines, lawsuits or greenwashing findings naming it were found.
