Cirium announces deal that sees its aviation data power Perk’s next-gen flight emissions tracking

Cirium's step towards more a levelled-up corporate flight travel

Cirium, the global leader in aviation analytics, has announced a major step forward in sustainable travel, as it signs a landmark deal with Perk, the intelligent platform for unified travel and spend management. 

Through this agreement, Perk’s customers now have access to Cirium’s advanced flight emissions data via EmeraldSky, Cirium’s flight emissions tracking tool. 

It enhances visibility into the environmental impact of flight choices, helping businesses and travelers make smarter, sustainability-led decisions.  

For the first time Cirium’s flight-specific emissions data is marking a major leap forward for Corporate travel. 

The travel management platform is now leveraging Cirium’s forecast and flown emissions insights to provide travelers and businesses with accurate, transparent CO2 estimates at point of search.

Post travel, these insights feed into Perk’s intelligent reporting suite, supporting sustainability tracking and regulatory compliance for the 10,000 companies the platform supports worldwide. 

This integration strengthens Perk’s position as the "go-to platform for companies aiming to reduce business travel emissions responsibly and at scale", it said.

Jeremy Bowen, Cirium CEO, said: “Accurate flight emissions data is essential to monitor the travel industry’s path to reach sustainability goals, and Cirium is proud to be the trusted source behind one of the most widely used corporate travel platforms.

“This partnership with Perk reflects the growing demand for credible, science-based data for the flight portion of the travel experience, and thanks to EmeraldSky, Cirium can now provide this to customers across the world who prioritize sustainability when booking flights and choosing their routing.”

Jean-Christophe Taunay-Bucalo, president and chief operating officer of Perk, said: “We’re thrilled to partner with Cirium to bring trusted, high-quality flight emissions data into Perk. 

"CO₂ tracking is essential, but for most teams it’s been a manual, time-consuming task. By combining Cirium’s trusted data with Perk’s intelligent platform, businesses can eliminate that repetitive manual work and move beyond estimates to automated, reliable insights that support compliance and meaningful reductions.”

This news builds on Cirium’s long-standing relationship with Perk, and follows the Group’s 2025 acquisition of AmTrav, an existing Cirium customer, which focuses on the US market.
