Our Commitment to a fossil-free internet by 2030
Our commitment
At Heatherstack, we are committed to ensuring that the hosting and data center infrastructure we use will be powered by 100% fossil-free energy every hour by 2030.
This means that for every region in which we operate, the hosting infrastructure we use – including those purchased or rented from other providers – will operate using 100% fossil-free energy and this generation will be supported by credible claims based on the Green Web Foundation’s provider verification criteria.
For questions about this commitment, please contact Joe Lovell at [email protected]. A machine-readable summary of our hosting suppliers is published at heatherstack.com/carbon.txt.
