Bouygues reports detailed Scope 1, 2, and 3 emissions with SBTi-validated targets across all six business segments, but undermines credibility through intensity-based Scope 3 targets on buildings instead of absolute reductions. Critical gaps: no group-wide renewable energy commitment, zero water management strategy despite global operations, and unverified supplier engagement. A large conglomerate disclosing selectively.
