Cooper Parry's footprint rose 31% in two years to 8,545 tCO2e in its 2025 financial year, almost all of it from its supply chain, even though its direct emissions fell 94% and its electricity is now renewable under certificates. Its targets are SBTi-validated, but its supply-chain targets are per employee and it allows offsets for up to 10% of residual emissions. Only part of its data is assured, by a consultancy it pays.
