15 years of Responsible
& Sustainable Practices

The story behind
Sustainable Square
Sustainable Square was built on a simple belief: that sustainability, done properly, is a powerful lever for long-term organizational performance.
For 15 years, we've combined advisory expertise with technology to help organisations move from ambition to impact, working at the intersection of sustainability, finance, regulation, and technology.
Our approach blends strategic thinking with practical execution, ensuring sustainability translates into more than just frameworks or reports.
This is driven by a culture that values proactivity, resourcefulness, integrity, and reliability, where teams anticipate change, solve with creativity, act with transparency, and deliver work that clients can rely on.

Global Standards
Deep GCC market knowledge combined with global ESG frameworks — IFRS, GRI, TCFD, SBTi, CSRD, and more.
Integrated
Advisory + Technology,
Squarely gives advisory work a permanent data backbone. Strategy and technology move together, not in silos.

Every recommendation is anchored to measurable impact, from cost of capital to regulatory compliance.

That Sticks
We focus on strengthening internal capabilities so sustainability strategies translate into action.
The team
behind the work
Behind Sustainable Square is a team of experts and executors that understands sustainability from every angle: strategy, reporting, operations, and execution. Combining strategic thinking with practical implementation, our team helps clients move from ambition to action.
