Pichai said the company was expanding the pilot program to intersections in Rio de Janeiro, Brazil, and beyond. The effort is part of a series of initiatives Google is launching to give consumers "more sustainable choices." The company will also show "authoritative information" panels from the United Nations and other sources when users search on Google for information related to climate change, Pichai said. Today we're sharing new ways people can use our products to make sustainable choices, including tools to book flights or purchase appliances with lower carbon footprints, a Nest program to support clean energy from home, eco-friendly routes on Maps & more. The company is also introducing a new feature in Google Maps beginning in 2022 that will allow users to pick the most fuel-efficient driving route when navigating.

Amazon's 2019 Climate Pledge calls for a commitment to net zero carbon across their businesses by 2040. Since then, the company has reduced the weight of their outbound packaging by 33%, eliminating 915,000 tons of packaging material worldwide, or the equivalent of over 1.5 billion shipping boxes. With less packaging used throughout the supply chain, volume per shipment is reduced and transportation becomes more efficient. The cumulative impact across Amazon's enormous network is a dramatic reduction in carbon emissions. To make this happen, the customer packaging experience team partnered with AWS to build a machine learning solution powered by Amazon SageMaker.
