Sustaining 5-Star Performance: How SGI Became First Among Their Peers With EVORA’s Support
"This strong GRESB 2025 result reflects years of structured, long-term work to strengthen our processes, improve data quality, and embed sustainability into our strategy. EVORA’s support has been key in strengthening our sustainability reporting and performance management, improving transparency, data reliability, and alignment with international best practices.”
- Roberto Loiola, CEO
The Challenge
The GRESB Infrastructure benchmark is becoming increasingly competitive, with the threshold for achieving a 5-star rating rising year on year.
Maintaining 5-star status is no longer a case of keeping performance steady, it demands continuous improvement, deeper data coverage and demonstrable progress across a broad set of sustainability indicators.
Against this backdrop of rising expectations, SGI continues to rely on EVORA’s expertise to refine their sustainability strategy and streamline their GRESB submissions.
Our Approach
EVORA has supported SGI with their GRESB Infrastructure submissions since 2021, focusing on closing gaps in sustainability performance and curating accurate, compelling evidence to meet GRESB’s rising standards.
In 2024, EVORA conducted a comprehensive Physical Climate Risk Assessment to identify climate-related hazards across the portfolio, quantify their potential impacts and prioritise mitigation actions.
The insights generated not only fed directly into SGI’s long-term resilience strategy but also strengthen this year’s GRESB submissions by demonstrating a proactive approach to risk management and climate adaptation.
Key Outcomes
EVORA’s strategic support has contributed to a consistent and significant improvement in SGI’s GRESB performance, reflected in their score progression:
| Year | GRESB Score out of 100 | Peer Score out of 100 | Peer Group Average | Star Scoring out of 5 |
| 2023 | 93 | 89 | 85 | ★★★★ |
| 2024 | 96 | 90 | 85 | ★★★★★ |
| 2025 | 99 | 94 | 93 | ★★★★★ |
The 2025 outcome places SGI 1st among its peers in the “Natural Resources Transportation Companies – Maintenance and Operation” category, further strengthening their infrastructure sustainability performance.
Alongside this achievement, SGI has successfully maintained a 5-star GRESB rating, demonstrating sustained commitment to sustainability leadership rather than one-off performance gains.
These results highlight the value of EVORA’s ongoing collaboration with SGI: strengthening both their internal sustainability performance and their external market reputation year on year.
