Introducing a groundbreaking open-access journal dedicated to advancing sustainable aviation practices. This journal aims to elevate the discussion, share innovative research, and drive impactful change in the aviation industry.

The Journal of Environmentally Compatible Air Transport System (JECATS) is a not-for-profit international scientific journal dedicated to the publication and public discussion of aspects of the air transport system with a focus on the environmental implications. JECATS publishes original research and review articles that especially, but not solely, combine areas of aerospace engineering, fuels, environmental analysis, climate change, economics, aviation climate mitigation, circularity and policy analysis. It includes aviation transport-related aspects and environmental effects from local to global scales. Research articles and review articles are considered for peer-reviewed publication.

These are complemented by invited perspective articles and communications contributions. JECATS ^[1] publishes special issues of the conferences of the non-profit international association ECATS AISBL (Association internationale sans but lucratif, www.ecats-network.eu)
A two-stage publication process involving the scientific discussion forum JECATS Discussions (JECATSD) is considered, in order to
• foster and provide a lasting record of scientific discussion;
• maximize the effectiveness and transparency of scientific quality assurance;
• enable rapid posting of new scientific results;
• make scientific publications freely accessible.

The journal’s topics resemble the scope and working areas of ECATS that combine aeronautical engineering, environmental and climate science and economical aspects. The interdisciplinarity is an important aspect and necessary for the needs of sustainable aviation.
