From this official Apple press release:

Apple® today announced a significant commitment by major supplier Lens Technology to run its Apple operations on entirely renewable energy. This unprecedented commitment, combined with zero waste compliance from all final assembly sites, furthers Apple’s efforts to help manufacturers lower their carbon footprint and reduce waste in China, helping to advance China’s transition to a new green economy.

Lens Technology has committed to power all of its glass production for Apple with 100 percent renewable energy by the end of 2018, as part of Apple’s industry-leading supply chain clean energy program announced last year. Lens is the first supplier to make a clean energy commitment for all of its Apple production, and will meet its goal through an unprecedented power purchase agreement with local wind projects.

Lens Technology is the first Chinese supplier to sign such a power purchase agreement, a notable first step in an important push by Apple. This will take time.

More immediately:

Apple is working with suppliers to help transform the environmental landscape in China, and is proud to announce all 14 of its final assembly sites in China are now compliant with UL’s Zero Waste to Landfill validation. The UL standard certifies all of their manufacturing waste is reused, recycled, composted, or, when necessary, converted into energy. Since the program began in January 2015, the sites have diverted more than 140,000 metric tons of waste from landfills.

And:

Apple has taken significant steps to protect the environment by transitioning from fossil fuels to clean energy. Today, the company is powering 100 percent of its operations in China and the US, and more than 93 percent of its worldwide operations, with renewable energy.

I can’t think of another company of size with this sort of self-awareness, this commitment to doing the right thing. Much respect, Apple.
