Nestlé, parent company of Purina PetCare achieved a high rank for sustainability and human rights issues on a ratings system, the Dow Jones Sustainability Index (DJSI), with an overall score of 92 out of 100 on the 2016 index.

The DJSI is an independent benchmark that measures the performance of the companies across three dimensions: economic, environmental and social. Nestlé received industry-best scores in all three dimensions.

To create the index, Dow Jones and RobecoSAM, an investment firm, invited the world’s largest 3,400 companies from developed and emerging markets to take part in its annual Corporate Sustainability Assessment (CSA). The CSA consists of over 100 financially relevant questions.

RobecoSAM’s DJSI index report on Nestlé noted that the company uses life-cycle assessment to evaluate the sustainability of their supply chain, including the 760,000 farmers supplying directly to Nestlé. To safeguard those farmers and others, Nestlé trained 11,242 employees on human rights.

Nestlé sustainability examples

Nestlé received an environmental score of 100 in recognition of projects like one in Switzerland, where Nestlé recently partnered with local farmers to open a biogas plant, which uses manure from cattle to generate renewable energy for a bottled water factory and the Swiss power grid.

Earlier in 2016, five of Nestlé Purina’s factories in North America, which create dog food, cat food and litter, achieved zero waste to landfill status. This marked Purina’s first zero-waste facilities in North America. Nestlé has committed itself to be landfill free worldwide by 2020.

In 2013, Nestlé installed a solar array on a pet food manufacturing facility in Atlanta Georgia. The array contains nearly 1,900 solar panels, which produce more than 585,000 kilowatt hours of energy each year. The energy powers equipment in various areas of the pet food production facility, including processing, packaging and warehouse.
