%X Astronomical observatories have been identified as substantial contributors to the carbon footprint of astrophysical research. Being part of the collaboration that is currently developing the medium-sized telescopes in the Cherenkov Telescope Array, a ground-based observatory for very-high-energy γ-rays that will comprise 64 telescopes deployed on two sites, we assessed the environmental impacts of one medium-sized telescope on the northern site with a life-cycle assessment. We identified resource use and climate change as having the most significant impacts due to telescope manufacturing and energy consumption during operations. We estimate life-cycle greenhouse gas emissions of 2,660 ± 274 tCO<sub>2</sub>e for the telescope, 44
