073. paper vs. pdf: calculating the carbon cost (ks3)
Compare the environmental impact of printing paper versus sending digital files to find out which option truly has the lowest carbon footprint.
We are often told to "go paperless" to save the trees, but is sending an email or downloading a PDF actually better for the planet? Digital files still need electricity to travel and be stored. In this lesson, we will do the maths to compare the carbon cost of printing paper against the hidden environmental impact of our digital habits.
