Do you write reusable code?
It perhaps goes without saying that it is inefficient to reinvent the wheel, yet it happens daily in web design projects around the world. The carbon footprint of a website includes the emissions of the team that created it, from their office energy to travel emissions. When we write code that can only be used once but which serves common purposes, we waste not just time but also energy.
Writing reusable code might not be a fit for every project, but it does help make our work more commercially efficient and delivers results with lower carbon emissions.
