Explore any project site. Shortlist the ones worth pursuing.
Screen potential carbon project sites anywhere, on the same trusted data that project developers, standards bodies, and rating agencies rely on. Narrow a pipeline of prospect sites to the ones worth funding, under one annual subscription.

Until now, there was no low-cost way to screen dozens of candidate sites before committing to monitoring spend.
Free tools rely on modeled or composited biomass estimates, which means early site decisions often rest on uncertainty that is hard to quantify.
Every new prospect means re-running ad hoc analysis by hand, so results aren’t comparable across sites, analysts, or partner consultancies.
Draw a polygon, rectangle or circle on the map, or upload a shapefile, KML or GeoJSON. Screen one project or a whole shortlist.
Get instant carbon stock, change, forest cover, average density, CO₂e and the full annual time series once the project boundary is defined.
Save sites and notes in one org-wide workspace, synced across devices, and export any analysis as CSV for your models.

Chloris is the biomass data carbon markets trust most: measured and recognized by Verra. Explorer puts that same record behind every site you screen. Answers in minutes that you can stand behind.
Explorer reports measured, field-calibrated above-ground biomass from one consistent pipeline, not a composite of modeled or open-source layers.
Screen every prospect in Explorer first, so your budget goes only to the sites with the strongest case for development.
Triage a candidate site in under three minutes, and narrow 50 candidates to the 3–5 worth deeper due diligence.
Saved sites, notes and CSV exports are shared org-wide, so every analyst screens against the same record.
Chloris is an officially recognized Verra data provider. Validated with airborne LiDAR and spaceborne GEDI.

Screen sites for REDD+ biomass loss, ARR eligibility and IFM baselines at volume, using one consistent dataset across every analyst and project.
Screen and shortlist project sites before committing budget, and take the strongest sites forward with a consistent biomass history from 2000.
Compare a project’s claimed carbon stock and land-use history against an independent annual record since 2000, in minutes, before you commit capital.
Free tools show forest-cover change or a single-year biomass snapshot. Explorer gives a consistent annual biomass history since 2000 for the area you draw, with CO₂-equivalent.
No. Explorer provides the carbon-history input; methodology fit stays with your team or consultant.
No. Explorer shows what a site has held since 2000, which is the starting point a growth curve is anchored to.
No. Explorer is for assessment and decisions. A full Chloris data license is available for PDD and formal reporting.
Split it into parts, or talk to us about other solutions.
Explorer covers the pantropics and CONUS. Sites outside that area aren't available yet.
It uses the same biomass layer, so there's no re-baselining. Today you re-upload the polygon in the platform.
The number of users is unlimited. Saved analyses are shared across your organization. Number of analysis per organization is 100 annually.
CSV of any saved analysis, date-stamped. A printable PDF summary is in development.
12 months, matching the annual contract.
Viewer is a Free screening tool: pre-processed biomass estimates at 30m, on an annual record since 2000. Pan areas of interest and see a global record of carbon dynamics with no cost or commitments.
