The Dow Jones Sustainability Index has named Nestlé as the leading food products company - with a score of 88%.
The world-wide Index is based on an analysis of companies' economic, environmental and social performance, including areas such as corporate governance, climate strategy, supply chain standards and labour practices.
Nestlé also achieved the maximum score for the second year running in the Climate Disclosure Leadership (CDP) Index and the Climate Performance Leadership Index, both of which are published in the Global 500 Climate Change Report 2013.
Neil Stephens, managing director of Nestlé Professional, said: "The Dow Jones Sustainability Index rating, which positions Nestlé as the number one global food company is significant recognition of the work we have been doing for many years.
"Take, for example, initiatives that have halved our emissions since 2002. That includes switching from long-distance road transportation to rail, investing in wind power to supply some factories, and burning coffee grounds to provide energy at our coffee factories in the UK.
"Earlier this year, we announced that Nestlé UK had achieved its zero food and packaging waste to landfill target across all its factories. This, in turn, led us at Nestlé Professional to launch a free on-line waste management course, sharing learning with the industry, and giving operators practical advice and guidance on waste prevention and management strategies."
