Our sustainable approach
At Calder Rivers Trust, we believe that sustainable design isn’t just a choice, it is an obligation. The health of our natural world is at the heart of everything we do, and that includes our digital footprint. Our approach to building our website reflects our commitment to a world where both our rivers and our climate can thrive.
By using compressed images, simplified code, and optimised content, we ensure our online presence aligns with our mission to protect nature. Through these practices, we have kept our environmental impact to a minimum.
Impact: Our homepage produces just 0.12g of CO₂ per page load.
Performance: This makes our site cleaner than 71% of all web pages tested globally.
Measurement: We track our footprint using Website Carbon, which calculates footprints based on data transfer, energy use, and the carbon intensity of the electricity used.
