Greenhouse Gas Reduction Potential Through Bioheat for Remote Communities in Northeastern Ontario

open access: yesGCB Bioenergy, Volume 18, Issue 7, July 2026.
Heating infrastructure in remote areas has high potential for fuel switching, possibly leading to decreased greenhouse gas emissions. Using a simplified life cycle analysis approach, we show that woody residues from the forest industry have the potential to reduce greenhouse gas emissions compared to commonly used fossil fuels.
