Why energy efficiency matters
Electricity that powers consumer electronics — including gaming consoles — is generated from a mix of carbon-heavy fossil fuels and renewable sources. Roughly 75% of the energy and carbon footprint across XBOX’s value chain comes from fossil-fuel electricity powering consoles globally, and about 50% of that segment is attributable to gameplay itself. Identifying and implementing energy efficiency measures for gameplay — without degrading the experience — is environmentally advantageous and directly benefits players through reduced energy bills and cooler, quieter hardware.“But I’m just one little game?” Not true. Consider a title averaging 0.35 kW on a PC device, played 10 hours/week, with 80,000 weekly active users:
- 0.35 kW × 10 hours = 3.5 kWh per week, per user
- (3.5 kWh × 80,000 WAU) × 52 weeks = 14,560,000 kWh per year
- 0.334 × 14,560,000 = 4,863 metric tonnes CO₂e per year
What we want to achieve
The XBOX Sustainability Toolkit aims to:- Highlight opportunities for energy efficiency that lower the energy demand and carbon footprint of players.
- Provide targeted data on the best areas to introduce efficiency improvements.
- Let developers see the baseline energy performance of their titles on XBOX Series X|S.
- Deliver detailed, actionable reports where inefficiency is observed.
- Partner with developers and publishers on a reliable testing process.
The XBOX Sustainability Toolkit
GDK and Power Monitor tools
Real-time energy consumption feedback down to the millisecond. Establish a baseline, measure GPU usage granularly, and pinpoint inefficiencies. Includes an API for custom profiling and a devkit front-panel Power Load % readout.
Dynamic Power States (DPS)
Let the driver dynamically scale GPU power based on rendering workload. One API call —
SetDriverHintX(DRIVER_HINT_SET_DYNAMIC_POWER, 1) — can unlock 10–15% additional savings on top of Sustainability Toolkit techniques.Certification power reports
Certification produces a bespoke Sustainability Power Report measuring your title’s power consumption across common in-game areas. Contact your Microsoft rep to request one.
Partner Center dashboards
Studio-level view of power, energy, and carbon footprint for every released title, updated monthly. Compare month-over-month to measure the impact of updates.
Energy Efficiency Essentials
A curated checklist of proven techniques from XBOX Game Studios and pilot partners — passive and opt-in optimizations you can adopt today.
Case studies
Real results from Call of Duty, Halo, Minecraft, Fortnite, Gears of War, ESO, For Honor, Star Wars Outlaws, and more.
Platform baselines
Compare your title against measured platform averages:- Lab platform baselines — power averages by in-game area (main menu, loading screen, active gameplay, constrained state, and more), captured by Certification with PIX across >200 titles.
- Global platform baselines — anonymized AC-power telemetry from XBOX Series X|S consoles in the field, broken down by feature (4K, 60 FPS, HDR, VRR) and genre.
