As a leading global renewable energy company, Yingli Green Energy understands that the legacy we leave as a corporate citizen is not simply based on the types of products we make, but also the methods we employ in our own manufacturing facilities.
Our production processes rely on a combination of various energy sources such as electricity, natural gas, heat and water. We set annual energy consumption reduction targets that meet or exceed Chinese and International Climate Change goals, and employ ways to utilize primary waste streams for secondary purposes. To help mitigate our electricity usage, we continue to build PV systems that generate electricity specifically for our manufacturing facilities, and now have over 20MW of our modules installed on site.
We are also committed to monitoring and reducing the emissions created by our manufacturing processes, including but not limited to GHG, PFCs and other air emissions. We’re proud to be the first company in the global PV sector to obtain Product Carbon Footprint Verification from TÜV Rheinland, a leading worldwide provider of technical services highly respected in the solar industry. TÜV Rheinland’s assessment was conducted in accordance with international carbon footprint standard PAS 2050:2011, a publicly available and universally applied specification providing a method for assessing the lifecycle greenhouse gas emissions of various goods and services.
In line with our continuous improvement efforts, we actively measure our waste streams and constantly strive to reduce them. Each year, we update our reduction targets in order to ensure that we maintain the most efficient and environmentally friendly manufacturing processes possible. One example is our long term agreement with SiC Processing AG, in which SiC will recycle exhausted cutting slurries for Yingli Green Energy through 2020. For the past 3 years, SiC has expanded its annual capacity for the recovery of exhausted cutting slurries generated by our production processes to 15,000 tons in 2009, 30,000 tons in 2010 and 60,000 tons in 2011.
Yingli Green Energy is developing a Corporate Sustainability Report, scheduled to be released later this year that will further detail our commitment to the environment and community.
