Tilbury Douglas faced the challenge of aligning with increasingly stringent environmental regulations while also reducing its carbon footprint across various operational scopes. The company had already established a strong sustainability framework under its People, Planet, Performance (PPP) strategy but required a more robust carbon offsetting approach to meet its ambitious net-zero targets.
Key challenges included:
Tilbury Douglas needed a reliable partner that could support their carbon offsetting strategy with transparency and efficiency.
Tilbury Douglas adheres to strict carbon reporting regulations, including Annual Carbon Audits and the PPN 06/21 Carbon Reduction Plan (CRP), which publicly discloses emissions and reduction strategies. The CRP is updated annually and is mandatory for government projects exceeding £5 million (a requirement expected to expand to all public sector projects). Integrating carbon offsets into the CRP, enables companies to claim carbon neutrality.
Tilbury Douglas ESOS mandates energy regulations requiring annual progress reports and audits every four years. While ESOS primarily focuses on energy consumption (kWh) rather than carbon emissions, activities such as carbon offsetting and transitioning from diesel to HVO fuel can form part of a company’s action plan to demonstrate emissions reductions.
This structured approach ensures Tilbury Douglas remains compliant while actively reducing its carbon footprint.
After an extensive evaluation of nine different carbon offset providers, Tilbury Douglas selected One Tribe for its transparency, efficiency, and strong project portfolio. One Tribe provided the company with a streamlined process for for sourcing and procuring high-integrity carbon offsets, and ensuring compliance with sustainability regulations.
