The corporate travel software provider onesto has expanded its sustainability offering through a new partnership with SQUAKE. Together, they enable precise calculation, management, and compensation of CO₂ emissions from business travel.
onesto is the first Online Booking Engine (OBE) provider in DACH to fully integrate SQUAKE’s technology infrastructure into its platform, including the Carbon Verification Protocol (s (CVP™). The result is a seamless, end-to-end system that operates quickly, securely, and without any need for additional plug-ins or installations.
Once activated, users can instantly access reliable CO₂ data embedded directly into their daily workflows - improving efficiency while supporting auditability.
The integration also enhances existing CO₂ displays in search results and introduces emissions as a new sorting criterion. Companies benefit from scalable configuration, high security, and sustainable cost efficiency - a solid foundation for long-term, climate-conscious business travel management.
Through the integration, onesto customers can access SQUAKE’s tools for both carbon measurement and compensation. CO₂ emissions can be compensated per trip or collectively at company level via certified climate protection projects.
Two product levels are available:
An adjustable CO₂ budget helps companies reduce emissions already at the booking stage. To support effective implementation, onesto and SQUAKE also offer joint workshops to help organizations achieve their sustainability goals.
This integration creates real value for our customers, empowering them to make business travel more sustainable. Together, we’re developing solutions that make emissions transparent, enable targeted reduction, and support climate-friendly travel decisions.

At SQUAKE, our mission is to make sustainability simple and transparent for every company. This partnership with onesto shows how climate solutions can become a natural part of business processes - allowing companies to track, manage, and reduce their emissions with precision.
