Xbox has officially unveiled the Xbox Developer Sustainability Toolkit which is aimed to help creators reduce energy consumption and measure carbon emissions during game development processes.

The Xbox Developer Sustainability ToolKit includes resources that include:

• Power Monitor tools
• Certification reports
• Power consumption dashboards
• Best practices

Ubisoft and 343 Industries were named as early users of the Xbox Developer Sustainability ToolKit with 343 Industries able to reduce energy use by 15% without impacting the player experience at all.

Ubisoft and Xbox are co-developing an energy-efficient eco-mode for users.

Microsoft is reportedly gauging interest for an Xbox Game Pass ad-supported tier subscription with a new user survey exploring the potential addition of a $3 subscription tier that would provide more features and benefits.

According to Windows Central, the survey suggested that a potential $3 subscription tier offering come with features, such as allowing users to play new first-party Xbox titles six months after launch, and would include Xbox’s slate of exclusive titles as well.

Multiplayer and EA Access games would also be accessible in this new potential tier offering.

With Game Pass reportedly falling short of it’s target in growth, back in October, it makes sense that they are exploring new tier offerings.

Xbox boss Phil Spencer has discussed the thinking behind Microsoft’s decision to abandon their plans to release a streaming-only version of its games console, for now, which was confirmed back in May.

The project, known as Keystone, as the topic of conversation as Spencer was interviewed on an episode of The Verge’s Decoder podcast.

“The console we built that now people have seen, Keystone, was more expensive than we wanted it to be when we actually built it out with the hardware that we had inside, and we decided to focus that team’s efforts on delivering the smart TV streaming app” Spencer explained.

Microsoft announced a partnership with Samsung earlier this year to bring an Xbox Cloud Gaming app to Samsung’s Smart TVs and Spencer said that the company is “really happy with the results there” thus far.

Spencer added that Xbox is “still focused” on the project but that pricing has proven to be difficult as they try to align it appropriately within the market.

“I don’t want to announce pricing specifically, but I think you’ve got to be $129, $99, like somewhere in there for [Keystone] to make sense in my view, that we just weren’t there,” Spencer said. “We weren’t there with the controller. And I love the effort. The reason it’s on my shelf is the team rolled up their sleeves and in nine months they built that thing. And a bunch of us took it home and it worked. It worked really, really well.”
