AWS Achieves 100 Percent Renewable Energy in 2025

AWS Sustainability: Hitting 100% Renewable Energy in 2025

AWS achieved its goal of powering operations with 100% renewable energy in 2025. But for enterprises, sustainability is now a board-level priority. Here’s how AWS helps you measure and reduce your cloud carbon footprint.

AWS Sustainability Milestones

Customer Carbon Footprint Tool

AWS provides free carbon footprint reporting in the Billing Console:

# Access carbon footprint data via API
import boto3

sustainability = boto3.client('sustainability')

# Get carbon footprint summary
response = sustainability.get_carbon_footprint_summary(
    StartDate='2025-01-01',
    EndDate='2025-12-31'
)

print(f"Total emissions: {response['totalEmissions']} MTCO2e")
print(f"Avoided by AWS efficiency: {response['avoidedEmissions']}")

Reducing Your Cloud Carbon Footprint

1. Use Graviton Instances

ARM-based instances use up to 60% less energy for the same workload.

2. Choose Efficient Regions

3. Optimize Idle Resources

• Stop dev/test instances outside business hours
• Use Spot Instances (repurpose unused capacity)
• Right-size over-provisioned instances
• Delete unused EBS volumes and snapshots
