- Abstract: Carbon offset programs are critical in the fight against climate change. One
emerging threat to the long-term stability and viability of forest carbon
offset projects is wildfires, which can release large amounts of carbon and
limit the efficacy of associated offsetting credits. However, analysis of
wildfire risk to forest carbon projects is challenging because existing models
for forecasting long-term fire risk are limited in predictive accuracy.
Therefore, we propose an explainable artificial intelligence (XAI) model
trained on 7 million global satellite wildfire observations. Validation results
suggest substantial potential for high resolution, enhanced accuracy
projections of global wildfire risk, and the model outperforms the U.S.
National Center for Atmospheric Research's leading fire model. Applied to a
collection of 190 global forest carbon projects, we find that fire exposure is
projected to increase 55% [37-76%] by 2080 under a mid-range scenario
(SSP2-4.5). Our results indicate the large wildfire carbon project damages seen
in the past decade are likely to become more frequent as forests become hotter
and drier. In response, we hope the model can support wildfire managers,
policymakers, and carbon market analysts to preemptively quantify and mitigate
long-term permanence risks to forest carbon projects.

We use machine learning to generate estimates of shade-tree cover and carbon stocks across a West African region.
We find that existing shade-tree cover is low, and not spatially aligned with climate threat.
But we also find enormous unrealized potential for the sector to counterbalance a large proportion of their high carbon footprint annually.

A carbon market is a market-based tool that incentivizes economic agents to align individual profits with the global utility.
We propose an adaptive mechanism design framework, simulating the market using hierarchical, model-free multi-agent reinforcement learning (MARL)
Numerical results show MARL enables government agents to balance productivity, equality, and carbon emissions.

This proposal paper describes the first systematic comparison of forest carbon estimation from aerial imagery, satellite imagery, and ground-truth field measurements.
Aerial imagery is significantly more expensive to collect and it is unclear by how much the higher resolution improves the forest carbon estimation.
Our initial results show that forest carbon estimates from satellite imagery can overestimate above-ground biomass by more than 10-times for tropical reforestation projects.
