This is the 15th consecutive year that Cummins released the Sustainability Report, which presented Cummins's sustainable development performance in 2017, including formulating and implementing various environmental protection goals and initiatives, and disseminating core safety standards to more people through community services. The proportion of female corporate leaders, and the number of global patents approved in the year. “We hope that through the actions of Cummins, the prosperity of the living and working communities will be promoted.†Recently, Cummins Chairman and Chief Executive Officer Tom Linebarger met with Fred Krupp, President of the American Environmental Association. Fred Krupp said, "We cannot just solicit and consume resources, but we should also create wealth for these communities and make continuous contributions." The main contents of the 2017 report include: Together with our customers, we achieved 340 cubic tons of carbon dioxide emission reduction. The company plans to reduce carbon dioxide emissions by 350 cubic tons by 2020. Through related activities such as education, environment, and equal opportunities that employees participated in, Cummins' corporate responsibility action covers about 3.3 million people. In 2017, nearly 1,000 work efficiency improvements were implemented within the company. In 2017, the proportion of Cummins women leaders was 23%. In 2010, the proportion was 16.42%. In the past five years, the annual R&D investment of the company has exceeded US$700 million for four years. The newly launched Cummins Customer Support Hotline handled more than 380,000 calls in 2017. At the same time, Cummins China also delivered a satisfactory answer to the community in terms of sustainable development. Beijing Foton Cummins Engine Factory has set up the world's largest solar power system, which uses solar energy to share some of the industrial power, which can reduce the annual emissions of 3,200 tons of carbon dioxide gas. Since 2015, Cummins has collaborated with international non-profit organizations in the development of professional children's safety courses and environmental education courses. They have jointly initiated the Cummins Powered Classroom Project and conducted safety and environmental education specifically for left-behind children in 12 schools nationwide. An alternative biotechnology system is used in the engine plant to improve wastewater treatment quality and utilization. Cummins actively participates in long-term initiatives to improve the community's environment: for example, in Wuxi and Fuyang, the “Green Taihu Lake†and “Green Han River†projects promote the ecological management of rivers and water sources, and promote the recycling of straw in Shanghai to reduce the pollution caused by straw burning. . In addition to the Sustainability Report, Cummins is also actively developing other sustainability-related reports, including the “Cummins GRI Data Manual†that meets the standards of the United Nations Global Reporting Initiative and the Water and Climate Archives of its Carbon Disclosure Project (CDP). The two reports will be released in June 2018 and July 2018 respectively. In the “News Weekly†2017 US Corporate Green Ranking, Cummins ranked 25th and was listed in the 2017 Dow Jones Sustainability Index North America list. This is Cummins's 11 consecutive honors since 2006.
