Deloitte has been named a Leader in the 2026 Verdantix Green Quadrant for Sustainability Consulting Services. This Verdantix Green Quadrant provides a detailed, fact-based benchmark of 15 of the most prominent sustainability consulting providers in the market across four service lines: sustainability corporate strategy; sustainability data management, reporting and disclosures; operational transformation; and sustainability financial advisory.
The Verdantix Green Quadrant recognizes Deloitte for its “market-leading view of innovation in sustainability consulting, embedding it not only in solutions and partnerships but also in how projects are structured and financed.” This analysis provides a graphical competitive positioning of four types of climate consulting providers: leaders, innovators, specialists and challengers. This marks the third edition of Verdantix’s evaluation, following earlier assessments in 2022 and 2024, and Deloitte was once again recognized as a Leader for its strong momentum and capabilities.
We’re proud of this recognition from Verdantix, which reflects how the sustainability consulting landscape continues to evolve. Today’s leaders understand that sustainability is a smart business decision. They’re focused on practical investments that can help strengthen organizational resilience, lower costs, and open new revenue streams. Deloitte is uniquely positioned to deliver on these expectations with innovation at the core of what we do. Our advanced technology and artificial intelligence (AI) capabilities enable measurable and scalable outcomes, and our end-to-end approach enables Deloitte firms to stay with clients through each stage of their sustainability transformation.
- Jennifer Steinmann, Deloitte Global Sustainability Business leader.
The Verdantix Green Quadrant highlighted how Deloitte’s work “draws on digital tools, ecosystem partnerships, and novel commercial models that focus on business priorities and accelerate outcomes,” noting that Deloitte offers “innovation as a systemic capability, not just a service add-on.”
The report also recognized Deloitte for its “comprehensive services for firms with ever-evolving sustainability priorities—Deloitte focuses on helping organizations navigate the evolving sustainability landscape by combining strategic advisory, innovation-led solutions, and operational transformation. This makes it a strong partner for firms facing competing priorities and diverse internal stakeholder demands, particularly when sustainability agendas evolve over time and clients need continuity. Deloitte’s scale and integrated capability set enable it to support end-to-end transformations while allowing organizations to stay with a single provider as their priorities shift from strategy to implementation and reporting.”
