The climate crisis needs better forest monitoring

Thriving forests are essential for limiting global heating. To better track forest emissions and hold the right people accountable, we need accurate, reliable, and up-to-date data. That’s where Sylvera comes in.

Shortcomings hinder current
measurement efforts:

High uncertainties

Conventional methodologies result in either underreporting or overestimation of GHG emissions.

Insufficient coverage

Limited data on the forest carbon cycle - geographically, and across ecosystems.


Data gaps, method variations, and reporting issues erode monitoring efforts.

State-of-the-art tech

We’ve pioneered the world’s most accurate measurements of above-ground biomass for forests and discovered two critical facts: carbon stocks have been significantly underestimated, and emissions from forest loss and degradation may be greater than what was previously thought.

Sylvera already uses cutting-edge laser scanning technology to collect this data on the ground. We’re now expanding our capabilities to collect calibration data for further carbon pools (below-ground biomass, soil, and others), and to validate the resulting models with direct measurements of carbon in the atmosphere.

We're seeking funding opportunities to make our proprietary data sets accessible and ensure this information is actionable for the widest possible audience.

case study
hectare highly-accurate above-ground biomass map

In 2022, we partnered with the Government of Mozambique through the Monitoring, Reporting and Verification Unit of the National Fund for Sustainable Development to produce a highly-accurate 50,000 hectare map of the above-ground carbon stocks in Mozambique, using multi-scale lidar and machine learning. The data collection completed was equivalent to scanning seventy thousand football pitches, making this the most laser scanned forest in the world.

greater accuracy than conventional methodologies

Our proprietary measurement system is underpinned by methods that are up to 13 times more accurate than conventional methodologies. Using these methods, we found classical approaches significantly underestimated the carbon stock of the sampled area. This was greatest for large trees (those above 40 cm in diameter), which only represent 10% of all trees in the study area by number, yet make up 50% of the total carbon stock.


These findings will be used to calibrate a state-of-the-art monitoring, reporting, and verification (MRV) system over the subtropical forests of Zambezia province, and demonstrate that these forests are more valuable as carbon stores than previously thought. These results are currently being prepared for publication (Demol et al., in prep).



Terrestrial laser scans were collected from six 1 hectare plots, providing high-density point clouds describing tree structure down to individual leaves.


Individual trees were segmented from these point clouds, and their woody structure modelled using cylinders, enabling whole-tree volume estimation.


These volumes were combined with species information from conventional inventory measurements, to generate highly-accurate 10m resolution above-ground maps.


To upscale our measurements, we collected 2,000 hectares of slow-flying and 50,000 hectares of fast-flying airborne lidar data, at different heights above the canopy.


We extracted various independent metrics from our airborne data, including canopy height maps, terrain, and forest structure…


…and used machine learning and our 1-hectare above-ground biomass maps as training data to upscale our estimates to six 300 hectare areas, and again to span an incredible 50,000 hectares of miombo woodland.


Finally, we used proprietary machine learning methods, applied to satellite data, to unlock full coverage over the entire province of Zambezia.

Our team

We have built a team of experts, including a dedicated field science unit who collect calibration data on month-long expeditions in key forested areas around the world. This capability allows our in-house data scientists to build highly accurate machine learning models, integrating data from satellites and other sources, to accurately predict forest carbon stocks.
