“…Ekeh et al [40], in Kampala, Uganda, used the GHG emission factors found in the study by Pennise et al [33] to compare with emissions from charcoal production in a CH 4 -free process technology ("PYREG methane-free charcoal production equipment"), using wood from a sustainably managed plantation. The established FU was 1 kg of charcoal at the C2G boundary and analyzed the GWP.…”

New technologies and emissions controls have been developed for the production of charcoal, but are not widely used in the industry. The present study seeks to evaluate the potential environmental impact of these new technologies as compared to traditional ones. A Life Cycle Assessment (LCA) of Brazilian charcoal produced with different technologies without and with the combustion of the gases in burners or furnaces was carried out. The inclusion of furnaces for the combustion of gases reduces all categories of potential environmental impacts by approximately 90% in both a circular masonry kiln and a rectangular masonry kiln with gas combustion. In the process of producing charcoal (gate-to-gate system boundary), in terms of climate change, the rectangular masonry kiln with gas combustion was approximately 63% less impactful than the circular masonry kiln with gas combustion. In the gate-to-gate analysis, the rectangular masonry kiln with gas combustion presented the best performance when not considering NO 2 and SO 2 . Considering these emissions, there were changes in the impact categories of particulate matter emission and terrestrial acidification, and the circular masonry kiln with gas combustion presented better performance (for cradle-to-gate system boundary). The process in a rectangular masonry kiln without gas combustion presented a greater contribution to the categories of terrestrial impact ecotoxicity (98%), due to the emission of acetic acid especially.

In many regions of Sub-Saharan Africa, charcoal plays an important role as energy source but is widely perceived as a major driver of deforestation and forest degradation. This narrative, however, is mostly based on research within primary production regions. Though space-borne remote sensing applications can be useful in monitoring such large-scale production modes, environmental effects of household-level production are less easy to assess. Therefore, the present study employs an unmanned aerial system (UAS) to assess the impact of small-scale charcoal production on the vegetation density in the immediate vicinity of production sites. The UAS data was complemented by field measurements and very high-resolution WordView-2 satellite imagery. This approach revealed only small differences between charcoal production sites and reference plots which were usually evened out after 20–25-m distance to the plot centre using a concentric ring analysis. Results further show that a distinction between different land-use practices is difficult, even with the high spatial resolution provided by a UAS. Thus, more research and new approaches are needed to evaluate the role of small-scale charcoal production in deforestation and forest degradation processes against the background of other human activities. However, to exploit the full potential of UAS for monitoring environmental effects in charcoal producing areas, official regulations need to be clearer and more reliable.
