Frequently asked questions
How much does a carbon offset cost?
Voluntary offsets range widely — from a few to over 100 per tonne — depending on the project type and quality.
Are all offsets equal?
No. Look for independently verified projects (for example Gold Standard or Verra) and check permanence and additionality.
Should I offset or reduce?
Reduce first, then offset what you cannot avoid.
