Our 2026 report: The Integrity Gap

This survey was conducted to understand how concerns about project integrity are influencing real-world investment decisions in nature and carbon markets.

We asked respondents a series of questions focused on three areas: how integrity concerns affect investment decisions, how leaders perceive the overall quality of available projects, and what would most increase their confidence to invest. The aim was not to measure intent alone, but to understand where and why action is breaking down.

58%

Of sustainability leaders say concerns about project integrity have delayed, reduced or prevented investment.

18%

Only 18% of Chief Sustainability Officers trust the majority of nature or carbon projects on the market.

#1

"Independent, science-based assessments" would most increase buyer confidence to invest in projects.

Earthly undertook this research against the backdrop of five years of assessing nature-project quality through Keystone 3.0, our project assessment framework across carbon, biodiversity, and people integrity. We have independently screened more than 1,000 nature projects and found that fewer than 9% meet minimum quality standards for environmental integrity, social safeguards, or long-term climate and biodiversity impact. This raises an important question: are the concerns we see in project data reflected in the experiences of decision-makers?

These surveys are providing clear answer - and a clear signal for change.
