Canadian Satellites Tracking Climate Change from Space: The New Eye in the Sky

0 Comments

While climate change policies often focus on land-based actions, Canada is advancing its leadership in space-based climate science. Through satellites like RADARSAT Constellation, GHGSat, and the upcoming WildFireSat, Canada is building one of the world’s most advanced environmental monitoring systems from orbit.

Canada’s Earth Observation Fleet

Canada’s key climate-focused satellites include:

  • RADARSAT Constellation: Launched in 2019, provides daily radar imaging in all weather conditions.
  • GHGSat: Montreal-based company tracking methane and greenhouse gas emissions.
  • WildFireSat: Launching in 2026 to track wildfire emissions and spread.
  • International Missions: Canada collaborates on ocean and polar monitoring via Sentinel and Argo.
These systems support Canada’s environmental policies, disaster response, and scientific research.

How Satellites Help Fight Climate Change

Satellites provide tools to:

  • Track emissions: Identify methane leaks and industrial hot spots
  • Monitor ice melt: RADARSAT maps Arctic sea ice for navigation and research
  • Detect wildfires: WildFireSat offers real-time fire intelligence for emergency services
  • Verify carbon budgets: Data supports emissions reduction frameworks and carbon trading systems
They convert climate pledges into measurable, visual data.

Canadian Leadership in Space-Based Climate Tech

Canada leads in:

  • Open-access satellite data policies
  • Public-private innovation via GHGSat and CSA partnerships
  • AI-driven satellite event detection systems
  • Influence in global climate discussions (e.g., COP meetings)
This strategy blends diplomacy, technology, and environmental protection.

Challenges and the Road Ahead

Remaining challenges include:

  • Limited Canadian launch platforms
  • Processing large data volumes quickly
  • Securing long-term funding for next-gen satellites
Despite this, satellite-based climate monitoring offers one of the highest ROI tools in Canada’s climate policy toolbox.

Conclusion

Canada’s climate satellites are becoming essential to policy verification, disaster response, and environmental transparency. These high-tech orbiters are not just tools — they are Canada’s climate eyes in the sky, quietly watching the Earth and helping shape its future.
