“Digital preservation exists to safeguard knowledge for the future. But as the volume of digital content continues to grow, so too does the need to better understand the environmental impact of the systems, storage, infrastructure, and workflows that support long-term preservation. That is why the release of the new Carbon Footprint Toolkit by the Digital Preservation Coalition marks an important moment for the digital preservation community. The toolkit has been designed to help organizations undertaking digital preservation understand, measure, and reduce the carbon footprint of their activities in a practical and proportionate way.”
