Reduce wildfire emissions

Emissions

Fire emissions vary based on fuel load, moisture, and weather. High-intensity wildfires generate the most emissions, especially in fuel-heavy ecosystems. Land managers can influence emissions through pre-fire planning, prescribed burns, and fuel management.

Reduce wildfire emissions

Fire emissions vary in composition and amount depending on the composition and quantity of fuels, the fuel moisture, and weather conditions during the fire (Hunter and Robles 2020). Wildfires that produce the greatest levels of emissions occur in ecosystems with high fuel loads, during weather events that drive fire growth faster than it can be suppressed. These conditions tend to correspond with higher-intensity and higher-severity fires, which consume more fuels and create more emissions. Land managers can, to an extent, influence the timing and quantity of emissions through pre-fire planning, both by implementing indigenous and prescribed fire actions; and through the management of fuels (North and Hureau 2011), either through removal or rearrangement.
