> We will design and operate our datacenters to support society’s climate goals and become carbon negative, water positive and zero waste before 2030. [...]
> By 2025, we will procure 100% renewable energy on a global scale, both significantly expanding and decarbonizing local electricity grids.
> Our datacenter designs are more water efficient than traditional enterprise datacenters, and our plan by 2030 is to replenish more water than we consume locally.
