Aiming for extra than simply internet zero

Local weather specialists throughout the globe agree: if we will’t drastically cut back carbon emissions, our planet will face catastrophic penalties. Microsoft has operated carbon impartial since 2012, and in January 2020 Brad Smith introduced our dedication to going carbon damaging by 2030. This isn’t a objective we will attain in a single straightforward swoop—it should take time, dedication, and plenty of small steps that coalesce into one thing larger.

Because the cloud enterprise grows, our datacenter footprint grows. In our journey towards carbon damaging, Microsoft is taking steps to roll again the impact datacenters have on the surroundings. Reaching this objective will take many steps, together with the implementation of progressive applied sciences which have but to be developed.

Many firms are reaching for internet zero emissions, however we’re taking it even additional. We’re not simply lowering our output to zero. We’re dedicated to lowering our emissions by half, after which eradicating the carbon we’ve emitted since 1975, to really go carbon damaging.

The journey to carbon damaging

A giant a part of going carbon damaging means utterly altering the best way datacenters function. Datacenters have adopted some sustainable strategies round cooling, together with open-air and adiabatic cooling. These strategies have helped to drastically cut back the water and power consumption of datacenters, however they’re not sufficient. At the moment, datacenters and the backup that powers them in peak load instances rely upon fossil fuels like diesel. Microsoft is working to alter that.

Our formidable targets to chop down our carbon footprint have necessitated exploration into numerous applied sciences. With every type of expertise, we’re figuring out the most effective mixture to implement primarily based on our general objective in addition to the precise datacenter areas and their native wants.

Liquid immersion cooling


Liquid immersion cooling is predicted to not solely assist remove water consumption however to decrease power consumption, at a minimal, by 5 to 15 %. As an additional profit, this closed-loop cooling system results in fewer server racks and smaller datacenter configurations. Datacenters take up a large quantity of area of their present configuration, making this an enormous benefit.

Grid-interactive UPS batteries


Grid-interactive Uninterruptible Energy Provide (UPS) batteries assist to stability provide and decrease power demand on the grid by directing microbursts of electrical energy to datacenters or the grid as wanted. These batteries retailer power at near 90 % effectivity and clean out intermittency from renewables. As we proceed to discover this expertise additional, we may doubtlessly prolong the period of the batteries from a couple of minutes to a number of hours—doubtlessly utilizing these long-duration batteries as a alternative for conventional backup turbines.

Clear energy backup


Clear energy backup has the potential to simply exchange typical diesel with much less dangerous emissions. Artificial diesel causes much less hurt to the surroundings and offers a much-needed bridge to utilizing renewables. Artificial diesel may even be utilized in diesel turbines with none modifications, lowering emissions on the best way to carbon damaging.


Hydrogen gasoline cells present an alternative choice for inexperienced backup power to datacenters and are nearly two instances extra environment friendly than combustion engines. The one output is food-grade steam that’s then recaptured and reused.

Energy your sustainability targets

These small steps add as much as one thing large. In response to a 2018 research, workloads on Azure could be as much as 98 % extra carbon-efficient than when working on conventional on-premises datacenters, and we’re making extra investments in the way forward for sustainability. By shifting your workloads to Azure, you’re making certain that your workloads are powered by datacenters with decreased emissions and lowered power consumption. We’re dedicated to not solely lowering our personal carbon footprint but additionally serving to you cut back yours.

Work with us towards a carbon-negative future.
