  The carbon footprint share of the information and communication technology
(ICT) sector has steadily increased in the past decade and is predicted to make
up as much as 23 \% of global emissions in 2030. This shows a pressing need for
developers, including the information retrieval community, to make their code
more energy-efficient. In this project proposal, we discuss techniques to
reduce the energy footprint of the MaRDI (Mathematical Research Data
Initiative) Portal, a MediaWiki-based knowledge base. In future work, we plan
to implement these changes and provide concrete measurements on the gain in
energy efficiency. Researchers developing similar knowledge bases can adapt our
measures to reduce their environmental footprint. In this way, we are working
on mitigating the climate impact of Information Retrieval research.
