What Does a Carbon Project Feasibility Study Cost — and What Are You Actually Buying?

The range and what drives it

In the voluntary carbon market, feasibility study costs exist across a wide spectrum:

What you are actually buying

A feasibility study is not a document. It is a risk assessment. The question you are asking is: if I commit $150,000–$500,000 to developing this project, what is the probability that it fails at validation, produces significantly fewer credits than projected, or creates reputational exposure for the buyers of those credits?

A study that produces an optimistic projection using standard assumptions does not answer this question. A study that has interrogated additionality against current regulatory data for the specific jurisdiction, validated baseline carbon assumptions against regional field data, and documented a risk register that a VVB auditor can scrutinise — that answers the question.

The cost difference between a $7,500 specialist study and a $75,000 consultancy study does not typically reflect a difference in methodological depth. It reflects consulting overhead. The question to ask any provider is not what they charge — it is what their conclusions are based on, and whether that evidence will survive independent review.

The risk you are eliminating

A carbon project that reaches PDD development and fails at validation has typically spent:

Total wasted development spend on a failed project: $80,000–$270,000 direct costs, plus opportunity cost of 18–24 months and the internal resources allocated. For institutional buyers, there is also the reputational cost of being associated with a failed project — which KPMG's 2024 ESG due diligence study identified as a deal-stopper in over 50% of transactions where material ESG findings surfaced.
