Walmart and HP are two examples of companies that are leveraging their buying power to increase sustainability throughout their supply chains.
Wal-Mart has launched a number of sustainable supply chain programs, including its Sustainability Value Network which directly involves its suppliers in a number of green initiatives. Wal-mart also implemented a supplier packaging scorecard, that formally rates suppliers on their progress toward developing sustainable packaging, as well as their ability to help Wal-Mart reach the company's sustainability goals to reduce waste, use renewable energy and sell sustainable products.
In 2008, HP published a set of guidelines to make their supply chain more sustainable. The guidelines help multinationals to better equip their suppliers. This initiative focuses on assisting small and medium-sized business to effectively compete in the global market while improving environmental standards.
Although there are barriers that need to be overcome, sustainable supply chains are part of a trend that is sure to continue.
