The PlayStation 5 won't waste as much energy as the PlayStation 4, Sony has said.
In a post on the PlayStation Blog, Sony Interactive Entertainment boss Jim Ryan said the PS5's suspend gameplay feature will consume less power than the PS4's suspend gameplay.
Ryan said Sony estimates the PS5 suspend gameplay can be achieved at around 0.5 W.
"If just one million users enable this feature, it would save equivalent to the average electricity use of 1000 US homes," Ryan said.
The announcement comes as part of the Playing for the Planet alliance, a new partnership set to appear at the UN Climate Summit.
Ryan will be there, he said, alongside others from the video game industry "to make formal commitments to contribute to the efforts of the UN Environment committee".
Ryan said power consumption savings on PS4 had a real impact. "For context, we estimate the carbon emissions we have avoided to date already amount to almost 16m metric tons, increasing to 29m metric tons over the course of the next 10 years (which equals the CO2 emissions for the nation of Denmark in 2017)."
Elsewhere, Ryan said Sony will investigate potential PS VR applications that can raise awareness of climate issues and climate experts.
