However, it's sorely needed action. Globally, the company drew on just five percent green energy in 2017, while Greenpeace's tech report card gave Sony a very lackluster D-rating in the same year. The announcement also follows a recent damning report from the Intergovernmental Panel on Climate Change (IPCC), which warned that "limiting global warming to 1.5 °C would require rapid, far-reaching and unprecedented changes in all aspects of society."

So it seems that Sony is pulling it socks up, and its US operations are now closer to falling in line with the green achievements already seen in the likes of Facebook and Google. As Sam Kimmins, head of climate group RE100 said of Sony's announcement, "This shows the business community what can be done, and we encourage all major companies to follow suit."
