Apple Inc on Tuesday called on its global supply chain to take new steps in addressing their greenhouse gas emissions and take a comprehensive approach to decarbonization.

The company will evaluate the work of its major manufacturing partners to decarbonize their Apple-related operations, including running on 100 percent renewable electricity, and will track its yearly progress.

About 55 Chinese companies that are suppliers of Apple, including display panel manufacturer BOE Technology Group Co Ltd, have promised to run on 100 percent renewable electricity so as to decarbonize their Apple-related operations.

Tim Cook, Apple's CEO, said in a statement that "Fighting climate change remains one of Apple's most urgent priorities, and moments like this put action to those words".

"We're looking forward to continued partnership with our suppliers to make Apple's supply chain carbon neutral by 2030. Climate action at Apple doesn't stop at our doors, and in this work, we're determined to be a ripple in the pond that creates a bigger change," Cook added.

As the impact of climate change is increasingly felt around the world, Apple also announced new initiatives and investments aimed at helping decarbonize the global economy and promote innovative climate solutions for communities.

These include significant investments in renewable energy in Europe, partnerships to support businesses transitioning to clean energy, and new support for projects that advance natural carbon removal and community-driven climate solutions around the world.
