It covers the environmental, social, and governance columns rather than treating ESG as a synonym for carbon, explains why embodied carbon and asset lifespan carry far more leverage than endpoint energy, and is blunt about the widely reported figures that will not survive assurance, including the avoided-emissions credit on your disposition certificate.
