Apple has launched a new energy initiative designed to promote the use of clean energy in China.

On Friday, the iPad and iPhone maker -- which has just revealed a refresh of its MacBook lineup[1] -- said that $300 million will be invested in the next four years between Apple and 10 initial suppliers.

The China Clean Energy Fund's goal is to "invest in and develop clean energy projects totaling more than one gigawatt of renewable energy in China, the equivalent of powering nearly one million homes," according to the company.

In a statement[3], Apple said that by joining suppliers with renewable energy sources through the scheme, the company is renewing its commitment to addressing both climate change and the increased use of renewable energy sources within its supply chain.

"At Apple, we are proud to join with companies that are stepping up to address the climate challenge," said Lisa Jackson, Apple's vice president of Environment, Policy and Social Initiatives. "We're thrilled so many of our suppliers are participating in the fund and hope this model can be replicated globally to help businesses of all sizes make a significant positive impact on our planet."

Initial suppliers involved in the fund include Catcher Technology, Compal Electronics, Golden Arrow, Jabil, Pegatron, and Sunway Communication, among others.

China's pollution levels are an increasingly urgent issue. An environmental census[4] conducted earlier this year claims that pollution sources have risen by 50 percent over the last decade and there are now nine million sources of pollution in the country.
