Carbon Trust Launches Water Standard

Coca-Cola Enterprises, Sainsbury’s, Sunlight and Branston are the first four organizations to achieve the Carbon Trust’s water reduction standard, launched today.

Carbon reduction is no longer enough, according to the consultancy, with water the new frontier in the battle against climate change — and businesses globally are not acting fast enough. The new Carbon Trust Water Standard is intended to spur companies into measuring, managing and reducing their water use.

According to a Carbon Trust study of 475 senior executives of large companies in Brazil, China, South Korea, the UK and the US published late last year, only one in seven firms has set a target on water reduction, or publicly reported on water performance. Of those businesses that do see water as a priority risk, two-thirds listed water availability as an issue.

To achieve the Carbon Trust Water Standard organizations must:

  • Measure water input from mains supply, surface water abstraction, groundwater abstraction and rainwater collection.
  • Measure water output as trade effluent.
  • Demonstrate reductions over time in both water inputs and wastewater produced. This can be done either in absolute terms, or in water intensity reduction in relation to turnover or product.
  • Achieve a passing score of 60 percent on a qualitative assessment of water governance, measurement and management. This assessment includes a site visit.

Carbon Trust worked with Sainsbury’s, Coca-Cola Enterprises, Sunlight and Branston — the four companies that have already adopted the Carbon Trust Water Standard — to develop the methodology for the new standard.

Paul Crewe, Sainsbury’s head of sustainability, engineering, energy and environment, says the grocer will achieve its target of a 50 percent relative reduction in water use by the end of next month, from a 2005/6 baseline. The company achieved this through a number of water-saving measures that form part of its 20×20 Sustainability Plan, including eradicating underground leaks, installing pre-rinse spray taps and low-flush toilets in all of its stores and investing in rainwater harvesting.

Coca-Cola has implemented a number of water-saving measures including using ionized air instead of water to rinse product packages prior to filling, reusing treated wastewater for landscape irrigation and truck washing, and advanced monitoring of water use and efficiency. The company set a goal in 2008 to improve water efficiency systemwide by 20 percent by 2012, compared with a 2004 baseline. Coke achieved that goal in 2011.

  1. Why is there no conversation about the CO2 that both packaged and dispensed sparkling beverages release into the environment?
