Website Carbon

Weather & Environment

Website Carbon API estimates the carbon footprint of any website by analyzing the data transferred per page load and calculating the resulting CO2 emissions based on the energy consumed by data centers, networks, and end-user devices that serve and render the page. As sustainability reporting becomes a growing expectation for Nigerian businesses, technology companies, and organizations seeking international investment or partnerships, the Website Carbon API enables developers to build green tech tools, sustainability dashboards, and web performance optimization workflows that include environmental impact metrics alongside traditional performance metrics.
