Google’s parent company and one of the most powerful corporations in the world, Alphabet Inc has also been named as one of the most eco-friendly. That’s according to the 2020 Carbon Clean 200 list created by As You Sow, a non-profit which promotes corporate accountability. All offices and company buildings, including Google HQ in Silicon Valley (pictured), are powered by 100% renewable energy, which removes an estimated five million tonnes of carbon dioxide from the atmosphere each year. The company also issued the largest corporate sustainability bond in history in August, with all proceeds from the $5.75 billion (£4.21bn) injection going towards supporting environmental and social initiatives.
