Apple announced on Friday that three more suppliers in China will use 100 per cent renewable energy in manufacturing its products by the end of 2018, reports Xinhua.
"As Apple continues our renewable energy efforts, we're thrilled to work alongside our manufacturing partners to advance China's green future," said Lisa Jackson, vice president of environment, policy and social initiatives at Apple, in an email to Xinhua.
The tech giant earlier saw four major suppliers commit to doing so by the end of next year in a supplier clean energy programme. according to Jackson.
Three more suppliers in China -- Sunwoda, Compal and Biel -- will join this programme and power all Apple production with renewable sources, Jackson said.
To fulfill this commitment, Compal Electronics, a final assembly supplier for iPad, is constructing solar panels totalling 12.6 megawatts across 224,000 square metres of rooftop space at its facilities in Nanjing and Kunshan in east China's Jiangsu Province.
Sunwoda Electronics, a Shenzhen-based battery supplier, has built a 50-megawatt solar farm in central China's Henan Province. The solar plant, which is 90-per cent owned by Sunwoda, will produce more clean electricity than the power that Sunwoda uses in battery production for Apple.
Biel Crystal Manufactory, a glass supplier in Huizhou of south China's Guangdong Province, derives 50 per cent of its energy from wind and solar. The company vows to increase the proportion to 100 per cent in 2018.
"These companies are leading the way to a greener supply chain in China, demonstrating that protecting the environment also makes good business sense," said Jackson.
In recent years, Apple has made efforts to improve the environmental impact of its production and operation.
Jackson said Apple is now powering 96 per cent of its global facilities, including offices, retail stores and data centres with renewable energy.
Meanwhile, Apple will continue to plant or protect enough fast-growing forests around the world to meet its growing paper demands in product packaging, Jackson said.
