  Software development companies are increasingly concerned about their impact
on the environment. This is translated into the incorporation of actions
related to software sustainability in their Corporate Social Responsibility
(CSR) document. CSR reflects a company's obligations to society and the
environment. However, we have found that companies do not always have the
necessary knowledge to be able to include actions related to software
sustainability. Moreover, there is still a lot of work to be done, as the
number of actions they incorporate is often insufficient. Taking all this into
account, we consider it essential for software development companies to have a
tool that allows them to assess their level of software sustainability, based
on the actions of their CSR, and to automatically provide them with a series of
improvements to advance their level of software sustainability. Therefore, this
paper introduces CSRE4SOC, a tool for the evaluation and monitoring of the
software sustainability level of software development companies according to
their CSR.
