Eleni Polychroniadou

The built environment contributes almost 40 percent to global energy-related greenhouse gas emissions.

With a background in environmental policy, Eleni Polychroniadou has spent her career trying to figure out how we address the climate crisis and make it something accessible that everyone can get involved in.

Sintali was launched in July 2020 by Eleni and co-founder Tom, with one clear mission: to make sure every building on this planet is green. They do that by verifying the impact of the built environment around the world, acting as an independent third party to validate sustainability claims made about buildings and ensure companies, governments and financial institutions are genuinely making a positive difference.
