CHALLENGE
Tritax Management LLP is the investment manager of multiple entities, including publicly listed REITs and real asset private equity funds. As the largest logistics assets investor in the UK, Tritax faces unique challenges in advancing its ESG performance, particularly within the GRESB framework.
Savills has supported the GRESB submission for four Tritax entities since 2021. A key challenge in this process is that most of Tritax’s assets are with Full Repairing and Insuring (FRI) leases, meaning that operational control over sustainability initiatives is limited. This makes engaging occupiers on sustainability matters and improving the coverage and quality of utility consumption data critical challenges. Additionally, Tritax seeks to use GRESB not merely as a reporting exercise but as a strategic tool to drive tangible ESG improvements across its portfolio.

SOLUTION
To address these challenges, Savills developed a tailored and proactive approach to GRESB reporting and ESG integration for Tritax.
Bespoke Data Collection and Quality Enhancement
- We designed a customised data collection template that streamlines the process and facilitates more structured and consistent reporting across all entities.
- Our approach goes beyond simple data aggregation; we actively analyse the data for anomalies, inconsistencies, and gaps, ensuring that Tritax receives high-quality, actionable information rather than just raw figures.
- Through our rigorous data validation process, we provide targeted recommendations to both Tritax and its occupiers to improve data accuracy and completeness over time.
Enhanced Occupier Engagement
- We proposed a structured engagement strategy with occupiers, fostering early communication and collaboration to increase response rates and improve data accessibility.
- By working closely with Tritax, we successfully improved data submission rates, offering tailored guidance to support tenants in their sustainability reporting efforts.
Leveraging Data for Broader ESG Reporting and Strategy
- We repurpose the data collected for GRESB to support other reporting requirements, including corporate ESG disclosures, regulatory requirements, and investor communications.
- Our team provides Tritax with bespoke sustainability insights, leveraging GRESB performance data to inform strategic ESG initiatives beyond the reporting cycle.
Strategic ESG Advisory
- Rather than treating GRESB as a standalone reporting requirement, we use it as a tool to drive continuous ESG performance improvement.
- We regularly update Tritax on changes within the GRESB framework and evolving industry best practices, ensuring that their ESG approach remains aligned with broader market trends and regulatory developments.
- By benchmarking Tritax’s performance against industry peers, we identify opportunities for targeted ESG enhancements, helping Tritax remain a leader in sustainable logistics investments.

RESULTS
GRESB Performance Improvement: We successfully maintained and enhanced the GRESB star ratings across all Tritax entities, demonstrating sustained ESG progress year over year.
Occupier Data Coverage: Our engagement efforts resulted in a significant increase in occupier data coverage, with all entities achieving at least 70% coverage and one entity exceeding 90%.
Improved Data Quality: By addressing anomalies and inconsistencies in utility data, we helped Tritax and its occupiers enhance the accuracy and reliability of their sustainability reporting.
Strategic ESG Impact: Through our continuous advisory services, Tritax is better positioned to leverage GRESB insights for broader ESG strategy development, ensuring that sustainability considerations are embedded in their investment and asset management decisions.
