Apple does not merely want its offices and facilities to run on clean energy. It wants to help the world’s most populous country do the same, too.

Apple on Thursday announced a new investment fund in China to promote clean energy use in the country. Apple and 10 partners will jointly invest $300 million over the next four years to develop clean energy projects that can create the renewable energy equivalent of powering 1 million homes.

“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.

The fund, named China Clean Energy Fund, will not be managed by Apple but by a third-party group that specializes in sustainable energy investments, according to Apple.

Apple for years touted its focus on reducing its greenhouse gas emissions in its global facilities and manufacturing processes. In April, Apple announced all its global facilities — including the Apple Park campus in Cupertino — reached 100 percent renewable energy. In China alone, Apple generates over 485 megawatts of wind and solar energy across six provinces.

But Apple is still responsible for a huge amount of emissions due to its massive global manufacturing infrastructure. Apple reported in 2017 that the company produced 27.5 million metric tons of carbon emissions, according to its latest Environmental Progress Report. Seventy-seven percent of Apple’s carbon emissions stemmed from manufacturing.

Apple’s China Clean Energy Fund comes at a testy time between Beijing and Washington, D.C., as the two governments fire early shots in a growing trade war. Apple CEO Tim Cook has traveled to both capitals in hopes of heading off a trade war so Apple would not be caught in the crossfire, according to a New York Times report in June.

The Trump administration told Cook it will not place tariffs on iPhones but Cook nonetheless was worried China would retaliate against Apple in another way, the New York Times reported.
