  These are the proceedings of the first teacher training of the Erasmus+
project No. 2020-1-PT01-KA203-078646 -- Sustrainable. The full title of this

Development Training and Education and the interested reader may know more

  The flagship contribution is the organization of two summer schools on
sustainable software production. The first summer school is moved due to the
Corona pandemic. It is now scheduled for July 2022 in Rijeka, Croatia. This
summer school will consist of lectures and practical work for master and PhD
students in the area of computing science and closely related fields. There
will be contributions from Plovdiv University, University of Ko\v{s}ice,
University of Coimbra, University of Minho, E\"otv\"os Lor\'and University,
University of Rijeka, Radboud University Nijmegen, University of Pula,
University of Amsterdam and Babe\c{s}-Bolyai University.
  To prepare and streamline this summer school, the consortium organized a
teacher training in Nijmegen, the Netherlands. This was an event of five full
days on November 1-5, 2022 organized by Ingrid Berenbroek, Mart Lubbers and
Pieter Koopman on the campus of the Radboud University Nijmegen, The
Netherlands. Sustainability is one of the themes within the strategy of the
Radboud University called `A Significant Impact', see

Sustainability plays an important role in education, research, and management.
  The contributions were reviewed and give a good overview of what can be
expected from the summer school. Based on these papers and the very positive
and constructive atmosphere, we expect a high quality and pleasant summer
school. We are looking forward to contributing to a sustainable future.
