Many of our suppliers operate in regions where water stress is a growing threat. We work with suppliers to improve water management in their operations and drive responsible withdrawal and discharge. In 2016, the most recent year data is available, production suppliers withdrew 31 million cubic meters of water associated with HP, 30% less than in 2015. This decrease reflects water withdrawal reductions among many of our suppliers, due to conservation projects ranging from awareness campaigns and improved maintenance to process efficiency improvements and water recycling. Stronger supplier water accounting practices also contributed to year-over-year variations in data. By the end of 2016, 80% of our suppliers, by spend, had set water withdrawal reduction goals. To identify supplier sites in water-stressed areas, we use water risk assessment tools such as the World Business Council for Sustainable Development’s Global Water Tool and the World Resources Institute’s Aqueduct Water Risk Atlas tool. For those sites as well as sites that manufacture water-intense product types or report high water intensity, we also assess suppliers’ water management strategies to identify how they can reduce impacts on local environments and communities. When appropriate, we work directly with suppliers and encourage them to use the Global Social Compliance Programme Environmental Reference Tools to enhance water use practices and other aspects of environmental performance. To further drive improvements, in 2018 we are adding water stewardship criteria to our supplier Sustainability Scorecard. See additional data and HP’s 2017 water footprint.
In 2016, the most recent year data is available, our suppliers generated 121,000 tonnes of nonhazardous waste associated with HP, no change from 2015, and they produced 51,000 tonnes of hazardous waste, a 6% increase compared to the prior year. The increase in hazardous waste volume is due to a major supplier including an additional stream of hazardous waste in its reporting, demonstrating better overall measurement and reporting. By the end of 2016, 62% of our production suppliers, by spend, had set waste-related goals.
Building on a successful zero waste to landfill project in Brazil, we launched a similar pilot project in 2017 at a site of a major supplier in China, with the objective of diverting more than 95% of waste from landfill through reduction, reuse, and recycling. This supplier is pursuing third party zero waste certification. We hope to expand this program to additional suppliers in China.
Greenhouse gas emissions:
Through December 2016 (the most recent year data is available), first-tier production supplier- and product transportation-related GHG emissions intensity, calculated as a three-year rolling average, increased by 4% compared to 2015. However, between 2015 and 2016 one-year intensity decreased by 6%. As we continue engaging our suppliers to become more energy efficient and use energy from renewable sources, we expect to achieve our goal of a 10% intensity reduction by 2025. WWF has publicly supported this goal,3 confirming the rigor of our goals-setting process. This goal is part of our suite of GHG emissions reduction goals that are components of our SBTivalidated science-based target.
We also advanced toward our goal of helping suppliers reduce their carbon footprint by cutting two million tonnes of CO2 emissions between 2010 and 2025. As of December 2017, our suppliers had achieved 53% of this target through new and ongoing energy efficiency projects, energy management programs, and renewable energy use motivated by engagement with HP. Combined, these efforts have avoided more than 1.05 million tonnes of CO2 emissions through 2017, and saved our suppliers $86 million in electricity costs alone.
