Fiji Water has hit back at critics of its eco claims by becoming the first water brand to publish its carbon footprint. It hopes that by joining the Carbon Disclosure Project - a scheme that measures emissions for the entire supply chain - it can boost its green credentials, despite the long distance the water is transported.

"Having an accurate account of our footprint and ensuring transparency means we can focus resources to cut emissions," said Thomas Mooney, senior vice president of sustainable growth at the company. Fiji Water claims to have carbon negative status, offsetting its 85,396 tonnes of emissions by 120%.
