Online retail giant Amazon has announced plans to make alf if its shipments carbon neutral by the year 2030.

The company, which ships millions of packages a year to shoppers, said that it will achieve that goal by switching to renewable energy sources and by asking suppliers to reimagine their packaging.

So, Amazon will be relying more on solar energy, and hopes to find way to cut packaging waste like other big companies including McDonald and Coca-Cola have announced. The company will also push for more deliveries to be made using electric vans.

“It won’t be easy to achieve this goal, but it’s worth being focused and stubborn on this vision and we’re committed to seeing it through,” Dave Clark, Amazon senior vice president of worldwide operations, said.

The new programme is being called Shipment Zero, and the company says that it is planning on publishing its carbon footprint later this year.

The new effort follows after the company spent two years mapping its carbon footprint, and determining how it can cut its carbon emissions and usage across the company.

Amazon is among the largest companies in the world, and has regularly jostled with the likes of Microsoft , Apple, and Alphabet to hold the title of most valuable company.

The company’s rival Microsoft has also engaged in climate conscious initiatives, including a $50m pledge in 2017 to fund an initiative to use artificial intelligence to take on the world’s environmental concerns.

Microsoft has also implemented an internal carbon tax that challenges different visions to cut carbon emissions or contribute to a company fund to work on energy improvements.
