Carbon Offset
A credit representing one metric ton of CO2 equivalent avoided or removed from the atmosphere, purchased to compensate for emissions elsewhere. Quality varies widely by project type and verification standard.
Why It Matters
Direct emissions reduction (solar, efficiency) is always better than offsets. If you do purchase offsets, look for Gold Standard or Verra-verified projects.
