1. Select project type

To create a new screening project, first select the project type: REDD, ARR or IFM. Then click the Next button.

2. Fill out project details

Next, fill out the project details. This is basic information about your project.

The following project details are mandatory for population:

• Project name: user input text
• Country: select from the list of countries
• Jurisdiction: select from the list of jurisdictions (applicable for REDD projects only)
• Project Start Date: select from calendar pop-out; this will impact the ex-ante carbon potential (avoidance or removals) estimation, which is undertaken from the project start date

There are also several optional project details that could be populated:

• Description: user input text about the project

• Developer: user input text

• Methodology: user input text; note that this does not impact the results of the eligibility assessment or carbon calculations; it’s for informational purposes only

  

Click the Next button once you’ve finished filling out your project details.

3. Upload or draw your project area

Once these details are populated, the project area needs to be added. You have 2 options.

Uploading your project area

Click the Upload button to add an existing project area in geojson format (note, the CRS must be EPSG: 4326 - WGS 84, and file size <20 MB).

<aside> ⚠️

Warning: When uploading geojson files with a large number of features (>50), you will receive the following message:

“File contains a large number of features. To continue, the “dissolve geometry” advanced option is recommended. Alternatively, you can split or dissolve geometries yourself into 50 features or less.”

To resolve this, click on the down arrow next to “Advanced options” and check the box next to “Dissolve geometries”. This will combine all features into one by merging their shapes (while still retaining individual site boundaries) into a single multi-polyon.

<aside> ⚠️

Warning: When uploading very large geojson files (>512 KB), you will receive the following message:

“File size is very  large. This may result in poor performance or failure to load statistics results. Use advanced options to set a coarser precision to reduce the number of coordinates.”

To resolve this, click on the down arrow next to “Advanced options” and adjust the coordinate precision (m). Smaller values keep the geometries more detailed at the cost of computation performance, while bigger values make the geometries coarser (i.e., reduce the number of vertices) to improve performance.

Drawing your project area

Click Draw to use your computer mouse to draw an area within the central map panel. Right click to finish drawing your project area. Click Draw Another Feature at the top of the central mapping panel to add additional areas, if necessary. Then click the Create Layer button to save your features.

Currently there isn’t an option to search by place name or coordinates. To make finding your area easier, switch to the satellite view on the right-hand panel.

Upon successful upload or area creation, the central mapping panel will zoom to your project area. Click the Next button to proceed with setting custom project parameters.

4. Customise project parameters

Depending on the project type you selected in Step 1 above, you can now configure a number of parameters, to customise the results to your project area. A brief description of the parameters for configuration under each project type can be found below.

For REDD projects

For ARR projects

• Performance benchmark discount:
  • The performance benchmark discount (PBD) factor represents how much of the project's performance is estimated to have happened without the project. A value of 0% means no discount (all vegetation growth is attributed to the project) while a value of 100% means complete discount (the project shows no significant growth to comparable unmanaged areas). This helps account for natural processes or existing trends that would contribute to carbon sequestration independently of the project.
  • The default value is 0%.
  • The user can adjust the value between 0 and 100%, to reflect baseline performance expectations.

For IFM projects

• Forest regrowth duration:

  • The time taken (in years) for forest biomass to return to pre-harvesting level via natural regrowth.
  • The default value is set to 40 years, based on typical scenarios.
  • The user can adjust the value between 30 and 100 years.

• Forest sequestration rate:

  • The annual mean carbon sequestration (tC/ha/year) due to forest growth under the project scenario. This represents the carbon accumulation in above-ground biomass when forests are managed sustainably without harvesting.
  • The default value is 2 tC/ha/year, based on typical scenarios.
  • The user can adjust the value between 0 and 5 tC/ha/year.

Once you’re happy with your parameters, click “Save”. The tool will start doing eligibility checks and calculating carbon potential instantly.
