While existing travel sites show the cheapest or fastest travel options, BookSmart24’s new app help you find the most CO2 and emission saving options for your chosen destination.

The platform empowers users to make smart and responsible booking decisions and understands that green travel doesn't have to be more expensive.

BookSmart24 aims to prevent CO2 emissions and other harmful emissions. BookSmart24’s SmartChoice shows users how to make booking decisions that are convenient and at the same time green and economical. Thanks to the app's clear and simple user interface, the end user is informed at a glance about the environmental impact of their trip.

A greener flight doesn't have to be more expensive. The cost difference for more CO2 efficient roads is often small. The platform calculates and compares the price, travel time and CO2 impact of each route based on its propriety algorithm.

SmartChoice prioritizes and recommends routes with the lowest carbon footprint, while ensuring fares and travel times stay within the estimated average of those routes. The app also adapts to the constantly evolving and rapidly changing mobility industry, and takes into account additional parameters including biofuels or the sustainability of airports or stations.

Currently, BookSmart24 serves several airlines. It also to soon focus on high-speed trains around the world, which will be later integrated into the app; this will allow consumers to combine train and plane connections in their travel planning.

The basic structure of the global high-speed global distribution system (GDS) has already been installed on the platform and the service will be provided in the coming weeks.

In the next phase, the city's multi-mobility concept (public transport, car-sharing, etc.) will be integrated into the platform to offer sustainable sightseeing trips around the world, with the goal to make BookSmart24 the global reference platform for sustainable travel.

In a statement American Airlines announced its investment in ZeroAvia, a leader in hydrogen-electric zero-emission aviation.

In addition to the investment, it has also signed a memorandum of understanding (MOU) with ZeroAvia and placed an order up to 100 engines of the company’s hydrogen-electric powertrain engine. These will power regional jet aircraft with zero emissions.

“Our investment in ZeroAvia’s emerging hydrogen-electric engine technology has the potential to play a key role in the future of sustainable aviation,” said Derek Kerr, American’s Chief Financial Officer (CFO). “We are excited to contribute to this industry development and look forward to exploring how these engines can support the future of our airline as we build American Airlines to thrive forever.”

ZeroAvia is working to achieve certain type certifications of its innovative propulsion technology that will pave the way for the engines to be incorporated into the regional jet market in the coming future. Its ZA2000-RJ powertrain is slated to be fitted into regional jets as early as the late 2020s.

“Having support from the world’s largest airline is a strong indication of the progress we’re making on the development of hydrogen-electric, zero-emission flight,” said ZeroAvia Founder and CEO Val Miftakhov. “We are focused on delivering sustainable travel, and are delighted that American, a visionary leader in the industry, sees ZeroAvia as a part of the future of aviation.”

This investment showcases another action on American’s path to achieve its aggressive climate goals, including achieving net-zero greenhouse gas (GHG) emissions by 2050.

In addition to the strategy and progress outlined in American’s recently published Environmental, Social and Governance Report, other recent sustainability efforts by the airline include:
