Aston has strong operational carbon data and a credible 2028 net-zero commitment backed by a £35.5m funded energy centre project. Supply chain emissions remain poorly mapped, renewable energy penetration is minimal at ~11%, and Scope 3 methodology gaps are acknowledged. No SBTi validation weakens target credibility.
