In order to use fonts digitally, font files need to be loaded and hosted creating emissions for both the host and user. Multiple fonts increase page load times and can cause issues for accessibility.

A lighter weight font for body copy keeps ink usage to a minimum when printing. https://medium.com/design-council/creating-climate-conscious-branding-8cc6ca4113bb
