Overview
ABSTRACT
The present article is a study, which illuminates the broad range of solutions offered by tribology to reduce CO2 and increase sustainability. Consistent application of the existing technologies for reducing friction and wear results in a medium/long-term reduction potential of >6-10 gigatons of CO2 or >15-26% of the 37.9 gigatons of CO2 emitted globally in 2019. In the future, humanity will use more efficiently resources to reduce energy and resource consumption without having to forego comfort. With its wide range of offers, tribology supports this technological revolution significantly.

INTRODUCTION
Compared to the CO 2 issue, the public debate perceives resource sustainability as an objective of secondary importance. Everyone talks about global warming, but the term sustainable development remains vague. Tribology has made significant contributions in both areas, offering enormous potential for both reducing CO 2 emissions and saving resources. Therefore, an easily understandable presentation of these important contributions is absolutely essential.

Both a technology and a science, tribology has a broad and solid industrial base. The aim of this study is to present how tribological research and developments can contribute to sustainable development through wear protection, condition monitoring, maintenance, repair and recycling, thereby contributing to resource conservation and increased material efficiency. As a key interdisciplinary technology, tribology will help reduce excess CO 2 emissions by 2040 or 2050. In the medium term, friction reduction will contribute to primary energy savings of between 8% and 13%, while wear protection and condition monitoring offer similar, not yet exact, quantifiable contributions to reducing CO 2 emissions as extending the service life of machines and their components generates less material consumption, thus reducing CO 2 emissions associated with the extraction and processing of raw materials. This study illustrates the solution approaches selected based on available...
