The internet contributes 3.7% of global carbon emissions, making it a significant polluter. Scientists at the University of Exeter have developed a tool called Digital Impact for Species to analyze the environmental costs of websites. Users can input a URL to receive a rating and insights on its ecological impact. The tool calculates emissions, energy use, and water consumption, aiming to promote sustainable internet practices rather than shaming websites. Suggestions for reducing website footprints include using fewer images, simple navigation, and green web hosting.
