Estimating carbon emissions from fossil fuel extraction in biomass-rich areas

FEBAC (Fossil Fuel Extraction in Biomass-Rich Areas Calculator) is an open-source tool we developed in partnership with Earth Insight that helps analysts estimate the potential carbon dioxide emissions from fossil fuel extraction activities in forested areas worldwide. It covers emissions from the extraction, transport, and combustion of fossil fuels as well as the deforestation associated with the process of extraction, including biomass and soil carbon release.

FEBAC provides flexible, scenario-based analyses for different data availability and project contexts, supporting climate change mitigation efforts by quantifying the impact of fossil fuel extraction. This information can be pivotal for decision-makers, researchers, and advocates working to make the consequences of oil, gas, and coal development more transparent.

With FEBAC and a limited amount of information about any forested geographic area with fossil fuel reserves, you can estimate the emission impact of future fossil fuel extraction in that area.

Key features of FEBAC include:

Customizable Analysis: Perform country, project, or block-level analyses with flexible scenario timelines. Clear instructions and a step-by-step guide simplify data entry.

Emission Estimates: Calculate both lower-end and higher-end emissions based on land disturbance and fossil fuel extraction and combustion up to the year 2100.

Data-driven Insights: Uses open-source data from Global Forest Watch (land carbon) and Energy Institute (fossil fuel data), among other academic sources as cited in the technical reference.

User-Friendly Interface: Designed for analysts with varying expertise, the tool simplifies complex data and generates reliable emissions estimates.

How It Works

FEBAC requires two types of data inputs:

  1. Fossil Fuel: An estimate for either reserves, extraction rate, and/or production expansion targets for the project(s) of interest.
  2. Land Disturbance: The area of the project block(s) to be developed and a specification of the expected level of disturbance (Low-Medium-High).

FEBAC accordingly estimates country- or region-specific fossil fuel project lifetimes and calculates emissions from the extraction, transport, and combustion of the fuel. FEBAC also estimates country-specific carbon content in forest biomass and soil, and deforestation rates due to fossil fuel extraction activities, to calculate emissions from land-use change. The tool produces two emission estimates:

  1. Lower-end estimate: Likely emissions based on typical project lifetimes and land disturbances.
  2. Higher-end estimate: Potential emissions, considering longer project lifetimes, including data on non-proved reserves (probable, possible) and more extensive forest disturbance.

These estimates are contextualized by comparing them to annual country-level greenhouse gas emissions.

Get Started

To use FEBAC, download the tool and open it in Microsoft Excel (highly recommended for optimal performance). Follow the instructions within the tool to enter data and run emission scenarios.
