For Researchers & Academics
Built for researchers and academics
No more manual data collection from six different registries. VCM.fyi provides a harmonized, daily-updated carbon market database with API access for reproducible research.
The challenge
Carbon market data is fragmented
Studying the voluntary carbon market means working with six registries that use different schemas, different terminology, and different data formats. Most research projects spend more time on data engineering than on the research itself. The result is smaller sample sizes, limited cross-registry comparisons, and findings that are difficult to reproduce.
No unified dataset
Each carbon registry has its own format, terminology, and data structure. Harmonizing data across Verra, Gold Standard, ACR, CAR, Isometric, and Puro.earth is months of work. Field names differ, credit taxonomies are incompatible, and project classification systems vary by registry. Researchers end up building bespoke data pipelines before any analysis can begin.
Manual data collection
Scraping registry websites, cleaning inconsistent records, and handling missing fields consumes research time that should go to analysis. Each registry has different export formats, pagination limits, and rate restrictions. What should be a straightforward data retrieval task becomes a multi-week engineering project that distracts from the actual research question.
Stale snapshots
By the time you have assembled a dataset, it is already outdated. Registry data changes daily with new issuances, retirements, and project updates. A static CSV downloaded three months ago misses thousands of new transactions, status changes, and project registrations. Reproducibility suffers when the underlying data keeps shifting beneath your analysis.
How VCM.fyi helps
One database, all six registries
VCM.fyi eliminates the data engineering bottleneck so you can focus on your research question. A single harmonized database with consistent schemas across all registries, programmatic API access for reproducible workflows, and daily updates so your analysis is never based on stale data.
Harmonized cross-registry data
One database covering all six major registries with consistent field names, normalized project types, and standardized credit categories. Updated daily. Every project record follows the same schema regardless of whether it originated from Verra, Gold Standard, ACR, CAR, Isometric, or Puro.earth, eliminating the months of data cleaning that typically precedes any cross-registry study.
REST API for programmatic access
Query projects, credits, transactions, and forensics data programmatically. Export datasets for statistical analysis in R, Python, or any tool that can make HTTP requests. The API supports filtering by registry, methodology, country, date range, and credit type so you can pull exactly the subset you need without downloading the entire database.
AI-powered analysis
Ask research questions and get source-cited answers drawing from the complete VCM.fyi database and real-time web search. Use the AI analyst to explore hypotheses, identify patterns across registries, or get context on specific projects and methodologies before committing to a full quantitative analysis.
Data coverage
The most comprehensive VCM dataset available
VCM.fyi aggregates and harmonizes data from Verra, Gold Standard, ACR, CAR, Isometric, and Puro.earth into a single queryable database. Every record is normalized to a common schema with consistent field names, project type classifications, and credit categories. The database refreshes daily from source registries so longitudinal studies can track changes over time.
