In this workshop we will enable participants to plan a project to estimate the carbon footprint of their digital archive. We will share how the CLOCKSS archive approached this, including how and when we engaged key stakeholders along the way, and explore ways that this could be generalised to be more broadly applicable throughout the international digital preservation community.

CLOCKSS began by setting out to find friends who could help us find a path. We were so lucky to find colleagues involved in the DIMPACT Project (https://dimpact.org/about). The DIMPACT community is focused on calculating and ultimately reducing the carbon footprint of digital communication and media companies and includes publishers such as Cambridge University Press, Elsevier, Institute of Physics Publishing, Oxford University Press, and Taylor & Francis.

We began by developing a component/functional map of our digital archive, and documenting:
1) The component parts of the system 
2) At a high level, how these components work 
3) How and where the service is used

Our aim was to unpack the ‘preservation’ black box that was part of the broader DIMPACT project diagram for all of digital publishing. 
 
The next step was to:
 
1.     Identify the significant energy-using components used to provide, maintain and deliver the preservation service and where each component was geographically located. For example, CLOCKSS securely preserves content in 11 different universities located in 7 countries.

2.    Identify how the preservation service is used, e.g. by how many users, the quantity or duration of service used per user, what devices the service is consumed on, what proportions of users use what kinds of devices, where the service is used (e.g. university, office, or home), etc. 

For each system component we then gathered relevant data (e.g. electricity source carbon intensities and usage and volumes of data transferred).

Finally, the carbon footprint will be estimated and we will be armed with the information to understand where and how we can make changes to reduce this. 

Now it is time to find friends, including those in the Digital Preservation Coalition, so that we can continue the journey together!
