The carbon footprint of a large rack mounted server is order-of-magnitude a ton of carbon a year. The first thing to understand is that doing things consumes time and energy and has a carbon footprint of its own. For a sense of proportion, a single economy flight between the USA and Europe is order-of-magnitude a ton of carbon.
