With the help of Black Box Partnerships, we picked 12 of the most forward-thinking organisations helping to make business travel more sustainable


SQUAKE’s end-to-end solution has been designed specifically for the travel industry as a single API plug-in to power precise carbon calculations for all types of activity, including flights, car and hotel according to national and international standards. Powering accurate carbon calculations and providing tangible compensation of all travel and transport related emissions, SQUAKE’s solution is fully customisable and partners can decide which calculation framework is most relevant to their product or programme. They can also create their own compensation portfolio to be selected from SQUAKE’s curated partner network, which includes certified climate protection organisations, as well as providers of innovative climate technologies and sustainable aviation fuel providers.

Black Box Verdict: SQUAKE’s carbon calculations are customisable and we particularly love that there is a ‘freemium’ entry level for small businesses. This Berlin-based business is one to watch.

eco.mio enables companies to achieve their climate goals while reducing costs. Its software seamlessly integrates into any online booking tool, incentivises employees to book greener travel options and allows companies to monitor the resulting carbon and cost savings through a performance dashboard. It determines company-specific benchmark behaviour of each planned trip at the point of sale. Its algorithm considers historical booking behaviours, pricing, market availability and the company’s travel policy.

Black Box Verdict: eco.mio meets the challenge of educating travellers and driving sustainable choices.


One of the leading online booking tools for meetings, off-sites and group stays, hubli offers hubli Green, a dedicated sustainability product for business travel and meetings, which allows meeting and event planners to choose venues and locations based on the lowest CO² emissions, book sustainable spaces and remove high waste items from meetings. Users have access to a ‘Where to meet?’ console allowing them to calculate the lowest carbon location for their meeting, including air, car, and rail travel options. Detailed pricing data per city also allows users to decide where to meet based on both CO² emissions and price.

Black Box Verdict: hubli Green easily enables businesses to put sustainability at the centre of their meetings, events and groups strategy.



Trees4Travel is an award-winning environmental ‘Tech For Good’ company providing carbon management technology to calculate and reduce emissions, through direct integrations into booking systems, API connectivity or simple file uploads. It calculates the impact of journeys, translates trips into trees, grows trees to restore forests, biodiversity and support indigenous communities, then reduces emissions today by connecting every tree to a UN CER renewable energy carbon credit. This year it launched Trees4Events, allowing any meeting to be a climate positive event from conception to compensation, ensuring events are not simply compensated but better planned from the outset to support the planet.

Black Box Verdict: This business is constantly evolving and we can’t wait to see what’s coming next from founders Nico and Elkie Nicholas.


CTM Climate+

CTM Climate+ sustainable travel programme consists of an ecosystem of services and technology solutions to help clients improve the sustainability of their travel programme by making more informed travel decisions. CTM’s proprietary online booking tool, Lightning, empowers the user to make more sustainable travel decisions by displaying carbon emissions for air, hotel, and car. It can filter and preference car results for EV and hybrid vehicles and sort flights and hotels by lowest emissions. The programme enables carbon offsetting at the final step of booking or end of the month, via CTM Climate+ or a client’s own offsetting solution.

Black Box Verdict: The investment made by this business to bring all important emissions data to the point of sale is admirable.
