Measuring carbon emissions at the Canada-France-Hawaii Telescope

Measuring the carbon emissions of the CFHT in 2019 reveals that the per employee emissions are 16.5 tCO(2)e, six times above the recommendation of the Paris Agreement, with similar to 63% due to the electricity consumption of the summit facility and similar to 25% to out-of-state air travel. Concerted efforts are underway to reduce this figure.
