The annual greenhouse-gas emissions of a planned neutrino experiment could be on a par with the production of 1000 cars. That is according to a new analysis that finds the main source of emissions of the Giant Array for Neutrino Detection (GRAND) project is different during the construction and operation of the project. The authors say their work is the first published assessment of greenhouse-gas emissions of a large-scale physics experiment and provides a methodology that could be used for future facilities >"Team finds that the annual greenhouse-gas emissions from the Giant Array for Neutrino Detection will be similar to the production of 1000 cars"
