Greenhouse Gas

The LEARN Tool: Everything You Need to Know About its Exciting 2025 Updates

Launched in 2021, the Land Emissions and Removals Navigator (LEARN) Tool was designed to help communities easily measure greenhouse gas (GHG) emissions resulting from land use changes. The tool enables users to intuitively analyze how forests and trees impact GHG emissions using land use and land cover data. In its latest update, Blue Raster collaborated with the Woodwell Climate Research Center, ICLEI – Local Governments for Sustainability, and the World Resources Institute to expand its features, giving local governments and landowners even more tools to understand and manage the carbon stored in their forests and trees.

Blue Raster supported the initial development of the LEARN Tool to address a significant gap in existing carbon accounting methods. Traditionally, previously analyses have focused on measuring their emissions from energy and transportation sectors, while the emissions and removals from land-use change and forestry have been overlooked. However, these land-based emissions and removals are responsible for a significant proportion of the carbon footprint, particularly in rural areas.

What’s New in the LEARN Tool?

LEARN Tool

The latest iteration of the the LEARN Tool was built with the ArcGIS Maps SDK for JavaScript and utilizes geoprocessing and image services hosted in an ArcGIS Enterprise environment.

The updated analysis in the LEARN Tool now includes the latest maps of Mature and Old Growth Forests, along with their protected status, offering a more comprehensive view of forest ecosystems. In addition to reporting net GHG emissions, the tool breaks down the total forest area by age and protection level, while calculating the carbon stored within each category. This deeper insight allows communities to understand the critical role forests play in carbon sequestration and climate mitigation.

With this information, users can easily identify high-value areas for preservation, develop strategies to protect mature and old growth forests, and take actionable steps to reduce greenhouse gas emissions. By highlighting the connection between forest preservation and climate impact, the LEARN Tool empowers communities to make informed decisions that align with their environmental goals.

Blue Raster also enhanced the LEARN Tool’s greenhouse gas analysis module with the latest National Land Cover Database (NLCD) data and added the ability for users to customize carbon factors with their own data. The default carbon factors used by the tool are derived from the Forest Inventory and Analysis database, providing a reliable foundation for calculating greenhouse gas emissions. Now, users can upload local carbon data tailored to their specific community, enabling more accurate and precise analysis.

Finally, the tool’s user interface has been revamped, making it even easier to run analyses and interpret results. These updates provide users with greater flexibility, improved accuracy, and a more streamlined experience as they work to understand and address the role of forests in greenhouse gas emissions.

New Features in the LEARN Tool Expand Functionality for Assessing GHG Emissions from Land Use

As the effects of a warming climate become more apparent, it’s increasingly important to consider ways to mitigate the impact of greenhouse gases on the atmosphere. Forests play a key role in the climate crisis, as about a third of human emitted greenhouse gases are sequestered in trees and forests. Analyzing the impact these forests and tress have using land use and land cover change data is a great way for municipalities to get a read on the effects of greenhouse gas emissions in their own communities.

Blue Raster is pleased to release the new build for the LEARN (Land Emissions and Removals Navigator) Tool. Built in partnership with Local Governments for Sustainability (ICLEI) and the World Resources Institute (WRI), the LEARN Tool allows for community inventorying of the effects of land use change on greenhouse gas emissions. This tool empowers policy makers, local governments, and community members to make informed decisions on environmental and climate policy.  Blue Raster developed the LEARN Tool to address a significant gap in existing carbon accounting methods. Traditionally, previously analyses have focused on measuring their emissions from energy and transportation sectors, while the emissions and removals from land-use change and forestry have been overlooked. However, these land-based emissions and removals are responsible for a significant proportion of the carbon footprint, particularly in rural areas.

LEARN Tool ScreenShot 1

The LEARN Tool simplifies the process of assessing a community's net greenhouse gas balance. Users can quickly select their area of interest by searching for a municipality name or uploading their own shapefile. With intuitive sliders, users can configure their desired land cover and tree canopy data and choose data for forest and land cover change between 2001 and 2019, as well as data for trees outside of forests for the selected time frame. The analysis is generated for the chosen location and time frame, and users can compare their results against other cities and municipalities. The tool provides emission factors, removal factors, and harvested wood products as view factors for the selected comparison area, with the option to download the results as a PDF or CSV file.

The latest version of the LEARN Tool comes packed with new features that improve its functionality. Users now have access to 1m Tree Canopy Data within the Chesapeake Bay Watershed, courtesy of the Chesapeake Bay Program and Chesapeake Conservancy, providing users with valuable insights into how trees and forests impact greenhouse gas inventories. The inventory period configuration screen has also been upgraded with new toggle widgets, offering users greater flexibility in selecting between 30m and 1m data in their analyses. These new features enhance the user experience and expand the tool's capabilities, making it even more valuable for communities looking to reduce their carbon footprint.

Blue Raster is excited to roll out this tool in its final form to benefit communities across the country.

National Fish and Wildlife Foundation Carbon Benefits Calculator

Most of our daily activities create greenhouse gas emissions which exacerbate climate change. Organizations like the National Fish and Wildlife Foundation (NFWF) spearhead efforts to mitigate these negative impacts by funding initiatives that offset emissions and create a greener earth. Blue Raster partnered with NFWF to create a robust Carbon Benefits Calculator. This tool estimates and visualizes the carbon impact of past and planned conservation efforts, restoration, and improved land management activities of NFWF.

NFWF Carbon Benefits Tool

NFWF wanted to innovate and optimize their existing in-house carbon calculator tool that was hosted in Excel. Blue Raster understands the need for a spatially explicit, robust tool that provides real-time calculations and eliminates hard-coded values to improve usability and usefulness. Additionally, this new tool enables NFWF to assess activities in various locations over different time series quickly and easily.

Our team created a web application backed by geoprocessing services in Python scripts. The tool allows a user to upload a spatial polygon for an area of interest to calculate carbon benefits, expanding the previous functionality that only allowed analysis at the county level. These calculations are done with python logic and geoprocessing services that are uploaded to ArcGIS Enterprise. Converting the tool from a spreadsheet-based calculator to a real-time and streamlined web application allowed for faster, easier, and more comparable results.

This tool uses various raster datasets including national land cover and carbon stocks to calculate the different properties and values such as climate, location, size, carbon stock, and land cover of the user submitted area of interest. Then, the tool automatically takes those values from the raster data and calculates the carbon benefits that would result from the selected project. NFWF can use this tool to estimate the carbon benefits of various projects and events such as invasive species clearing, crop and livestock use, thinning, fires, land transformations, over a 30-year period.

Previously, Blue Raster built out the Where We Work web map for NFWF to help illustrate the extensive geographic reach of their mission and impact of their conservation programs. Also, we built a proposal reviewer application and aided in NFWF's ArcGIS Enterprise installation.

We are excited to continue our collaborative efforts and work with a long-time partner by supporting NFWF with the Carbon Benefits Calculator and ongoing conservation efforts.

Estimating Community GHG Emissions from Land Use Change

As communities around the United States seek to mitigate the impact of climate change by reducing their greenhouse gas (GHG) emissions, the importance of land use to the GHG balance has become more apparent. About one third of human caused GHG emissions each year are sequestered in forests and trees but most communities do not include forests and trees in their inventories. To help fill this gap, the World Resources Institute (WRI) and Local Governments for Sustainability (ICLEI) developed the Land Emissions and Removals Navigator (LEARN) tool.

GHS emissions imagery

The LEARN tool provides an intuitive step-by-step workflow for communities to assess their net GHG balance based on land-use and land-cover changes. Once users have selected or uploaded their municipal boundaries and inventory period, the tool calculates land cover change using National Land Cover Database (NLCD) data. Users can then explore a change image to quickly see where areas are being converted to and from forests.

As the characteristics of the forests within the municipality impacts the amount of carbon emitted or removed, the change image is then compared to a carbon stock map developed from US Forest Service data based on the age and type of forest. NLCD tree canopy data is also used to identify addition or removal of trees-outside of forests to ensure a comprehensive assessment. Forest disturbance data for insects, fires, and other disturbances are also incorporated into the GHG balance. Finally, users can input the value of GHG removals from Harvested Wood Products (HWP) within the inventory period as HWP continue to sequester carbon.

Once the user has gone through the four simple steps to complete the audit, they are presented with an easy-to-understand table showing their community’s Net GHG Balance and the source of the emissions and removals. A PDF report and CSV data are also available to provide detailed analysis of the land-use and land-cover change with charts and graphs as well as the carbon factors for emissions and removals used.

The LEARN Tool was developed using the Esri JavaScript API and ArcGIS Image Server to provide the analysis.
