Indonesia Carbon Sequestration Calculator & Policy Analysis

This repository contains the Indonesia Carbon Sequestration Calculator, a FastAPI-based web application designed to calculate the required forest and coastal areas necessary to achieve Indonesia's 2050 Net Zero carbon emission targets. The computational logic is grounded in the IPCC 2006 Guidelines Volume 4 (AFOLU) Tier 1 methodology.

Key Features of the Calculator:

  • Dynamic Emission Modeling: Utilizes a 3-point emission model (Initial Year, Peak Year, Target Year 2050) to project the required carbon sequestration volume.
  • Land-Use Allocation: Computes the balance between existing available forest/coastal areas and the required new planting allocations.
  • Customizable Sequestration Variables: Allows adjustments for forest and coastal sequestration rates, root-to-shoot ratios (including below-ground biomass), degradation rates, and localized risk factors.
  • Interactive Data Visualization: Generates projection charts mapping emission trajectories against required mitigation efforts over time.

Included Analytical Report: In addition to the software, this repository includes a critical analysis report on the proposed "Compliance-Based Sequestration Certificate Scheme" for Indonesia (modeled after Australia's LGC scheme). The analysis evaluates logic gaps in translating energy-based models to biological carbon sectors, specifically addressing:

  1. Permanence and Reversal Risks in forestry.
  2. The Ex-Post Financing dilemma for capital-intensive restoration projects.
  3. Additionality concerns between "Existing" vs. "New" carbon sinks.
  4. Structural demand limits within state-owned enterprises (e.g., PLN).

Technical Stack: Python 3.11, FastAPI, Uvicorn, Jinja2, Pydantic.
