Anna Meegan, head of sustainability for Google’s devices and services unit, said in an interview that the company’s transport-related carbon emissions per unit fell 40 percent last year compared to 2017 by relying more on ships instead of planes to move phones, speakers, laptops and other gadgets from factories to customers across the world.

The company will offset remaining emissions by purchasing carbon credits, Meegan said.

Three out of nine Google products for which the company has detailed disclosures online contain recycled plastic, ranging from 20 percent to 42 percent in the casings for its Google Home speakers and Chromecast streaming dongles.

Writing in its bog,  Google committed to introducing some recycled plastic to products by 2022.

Sustainability standards werenow a part of Google’s hardware planning, Meegan said. Devices cannot clear the second checkpoint in the company’s design process unless they show that sustainable packaging and materials and ease of repair have been considered.

“We are fundamentally looking to build sustainability into everything we do”, she said. “It’s going to take us time to demonstrate progress.”
