On November 23, 2016, the first cleaner production evaluation index system of photovoltaic industry --Cleaner Production Evaluation Index System of PV cell Industry, jointly prepared by representative photovoltaic enterprises of China under the leadership of Yingli Green Energy and China National Institute of Standardization and the support of China Photovoltaic Industry Association and World Wildlife Fund, was officially released after being jointly approved by National Development and Reform Commission, the Ministry of Environmental Protection and the Ministry of Industry and Information Technology. This is very significant for guiding PV cell enterprises to promote cleaner production in an in-depth way, improve the level of energy conservation and emission reduction and pollution prevention and control, and promote the sustainable development and environmental friendliness of PV cell industry.

On May 27, 2011, Yingli and WWF China officially signed a MOU on the Yingli being selected as Carbon Emission Reduction Pioneer and the third-party technical advisor have also begun to formally assess Yingli's greenhouse gas emissions and work out a cooperation program for its joining in the Carbon Emission Reduction Pioneer Project.

On January 29, 2013, Yingli officially joined WWF “Carbon Emission Reduction Pioneer” Project. It became the first enterprise which joined “Carbon Emission Reduction Pioneer” Project in the photovoltaic field of both China and the world, and set a series of greatly look-ahead goals of greenhouse gas emission reduction. As of 2015,

(1) The strength ratio of greenhouse gas emission of manufacturing photovoltaic component per megawatt decreased by 13% in 2010;

(2) The strength ratio of greenhouse gas emission of products and services purchased decreased by 7% in 2010;

(3) The strength ratio of greenhouse gas emission of upstream logistics transport decreased by 10% in 2010;

(4) At least 4% of the total power consumption of the company is from renewable energy;

Meanwhile, Yingli will join hands with WWF to launch green production standards for the photovoltaic industry to reduce energy consumption, increase the proportion of renewable energy use, and reduce greenhouse gas emissions.

Through continuous efforts, Yingli has fulfilled ahead of schedule the commitment to the “Carbon Emission Reduction Pioneer” Project, which was originally planned to be fulfilled by 2015.

On January 20, 2012, Yingli declared that its polycrystalline photovoltaic component and monocrystalline photovoltaic component had finished its life cycle assessment of carbon footprint. The assessment is carried out in accordance with the PAS 2050:2011 international carbon footprint standard, which is an open standard for providing methods for assessing greenhouse gas emission within life cycle of a variety of products and services. The evaluation is controlled and certified by TUV Rheinland Group. According to the assessment results, the reduction of carbon dioxide emissions of the PV components of Yingli Green Energy will be much higher than the emissions during the next 25 years. It is reported that Yingli Green Energy is the first photovoltaic enterprise which passed the carbon footprint certification of Rhein TUV products in the world.

Since 2009, Yingli has held the system design workshop for four times. It invited well-known companies, research institutes and design institutes of PV upstream and downstream industry to attend the workshops, and provided a good platform for the industry to set standards, train talents and communicate and output. Up to now, it has fostered over 500 experts for the industry, which has promoted the overall development of the industry and built a bridge for exchange and communication.

The training class for developing countries

Approved by the International Cooperation Division of the Ministry of Science and Technology, Yingli opened the technical training class for developing countries in 2015 and 2016, and opened “the international training class for photovoltaic technology and its application” in Baoding City. It has trained nearly 40 students from 16 developing countries, such as Russia, Columbia, Thailand, Nepal, Brazil, Pakistan, India and Philippines, most of whom are technical backbones who are engaged in photovoltaic industry, technology and application in their country. Through receiving Yingli’s training, they have systematically studied the basic theory, preparation technology and application system knowledge of photovoltaic, thereby enhancing the level of photovoltaic technology and providing talents in photovoltaic for developing countries.

On September 21st, 2005, the “Renewable Energy Legislation Training Class”was opened in Baoding. As the organizer of thistraining class, Yinglilaid a foundation for the promotion and implementation of Renewable Energy Law in China. Meanwhile, the training class is also the first renewable energy training activity held by the National People's Congress.
 

Yingli is the first enterprise which suggested promoting and protecting the development of photovoltaic industry by legislation at the National People's Congress. Yingli is also the first enterprise which participated in the national renewable energy legislation for consecutive two times.
