Derwent London reports comprehensive operational emissions data with PwC assurance, but embodied carbon from its demolition-led development model rose 43% in 2025, offsetting operational gains. Supply-chain mapping is incomplete, net-zero relies on offsets, and water targets are absent. The company's circular economy strategy and BNG delivery are genuine, but the business model itself drives embodied carbon escalation.
