3. 💻 Tech industry’s footprint on climate 💻 2020 4% (✈) ⇒ 8% (🚗) 2025 Greenhouse Gas Emissions / world 🏭
4. 2020 Warmest year in EU ever recorded 2070 󰏃 50 C / 90 F ⏫
6. 🛠 reduction, capture, compensation ⚠ Today’s myths ⚠ - individual/organization carbon neutrality - capture/compensation-only aka greenwashing
7. ICT: -45% GHG emissions by 2030
8. SRE x DevOps x Sustainability • Change is necessary to improve • Breakdown silos • No blame culture • Small/frequent changes are better than big promises
9. Redefining reliability “The ability for a system to fulfill a mission in some defined conditions” Client future Client satisfaction &
10. SLOs • Common objective across teams (tech, product, ...) • Tooling that enables to keep track of that objective • Drag focus and enable proactivity Without SLOs Reliability “We expect 100% uptime” No clear objectives Climate impact ⇒ “Digital is clean, it has no impact” ⇒ No objectives at all
