Foreword The International Conference on Gears in Garching near Munich, Germany, is an established platform for researchers on and manufacturers of gears and transmission systems. At the 10th issue of the conference in September of 2023, gear experts discussed the latest developments and research results from the powertrain industry and academia. Given the increasing challenges of climate change and its impacts, acting in compliance with the UN Sustainable Development Goals is mandatory for all engineers today. Gear engineers must consider these objectives in their research and development activities and provide solutions that meet the technical requirements and contribute to achieving the UN goals. Greenhouse gas (GHG) emission is a primary driver for climate change. Reducing GHG emissions should be an urgent action for the combat against climate change. Therefore, the research on efficiency is assigned a key role. Several contributions in this report discuss the possibilities for further improvement in efficiency from different points of view, like gear design or lubrication. Other subjects of the conferences are Responsible Consumption and Production. H...
