Apple has blasted past this year’s clean energy goal by encouraging even more of its suppliers to use 100% clean energy.

Apple’s own operations have been running fully on renewables since last year, but of course, it’s huge manufacturing operation involves plenty of outside suppliers who don’t all have the same green ideals. Since last year, Apple has roughly doubled the number of “clean suppliers” in its supply chain, making 44 manufacturers using entirely renewable energy, which is a big step in the right direction.

“We’ve made it a priority to hold our suppliers accountable to the same environmental standards we observe and hope that our collaboration will show others what is possible,” said Apple’s Environment VP, Lisa Jackson. While we are proud of our announcement today, we won’t stop driving change within our industry to support the clean energy transition happening globally.”

The company has also allocated $2.5 billion in Green Bonds, used to fund environmental initiatives worldwide.

This means Apple has exceeded its original goal of bringing 4 gigawatts of clean, renewable energy into its supply chain by 2020 – it’s not only hit that target a year early but beaten it by a full 25%. Hopefully Apple won’t rest on its laurels, but use this to kick forward into even more ambitious initiatives to protect our environment and help combat climate change.
