A Wavestone study reveals that backups/resilience (29%) and identity and access management (16%) together account for 45% of the cybersecurity industry's carbon footprint. Encryption, contrary to expectations, has minimal climate impact due to decades of efficiency optimization. Practical recommendations include consolidating redundant IAM systems, reducing unnecessary log retention, and migrating contractor workstations to virtual desktop infrastructure. Backup redundancy remains the hardest area to optimize without increasing risk. AI-based security tools currently show negligible climate impact, though that may change by 2026–2027.
