Carbon Offset Cost Calculator
Offset budget by credit-quality tier, with tree-equivalent reality check.
What does neutralizing X tonnes actually cost? Depends entirely on quality: avoidance credits trade near ₹400–800/t, nature-based ~1×, verified removals 4× and up. Pick the tier honestly and budget accordingly.
For any business or project:Mitigation hierarchy: measure → reduce → then offset the residual with credits you can name and verify (registry, vintage, methodology). A tree absorbs ~22 kg CO₂/yr — "plant a tree" claims that ignore the 40-year wait are marketing, not accounting.
Screening-level estimate using published average emission factors. Audited disclosures (BRSR, GRI, CDP) require primary activity data and verified factors — confirm with your sustainability auditor.

Frequently asked questions
How much does it cost to offset a tonne of CO₂?+
Quality decides: bulk avoidance credits trade at ₹300–800/t, credible nature-based ~₹800–2,000, verified removals (biochar, mineralization, DAC) ₹3,000–30,000+. Cheap credits carry integrity risk that's increasingly a reputational cost — the tier selector prices the honest range.
How many trees offset a tonne of CO₂?+
A mature tree absorbs ~22 kg/yr, so a tonne needs ~45 tree-years — one tree growing 45 years, or 45 trees for one year, surviving drought, grazing and land-use change. 'We planted N trees' claims without survival accounting are marketing; the math here keeps it honest.
Should my business offset or reduce first?+
Reduce first, always: the mitigation hierarchy (measure → reduce → offset the residual) is what every credible standard and green-claims regulation now expects. Offsets bought instead of reductions are increasingly challenged; offsets bought after visible reductions are credible.
How do I avoid junk carbon credits?+
Demand four things: a named project, a recognized registry (Verra/Gold Standard/Puro), a recent vintage, and retirement in your name. Prefer removals over avoidance where budget allows. If a seller can't show the retirement certificate, walk.
