Obstacles to change include the primacy of having mission-critical capability and long equipment life cycles (which means fossil-fuel-powered equipment in use now, or coming into service shortly, will still be fielded in 2050). But defense forces can begin setting priorities for decarbonization by categorizing their emissions as those for which they are directly responsible and those resulting from the supply chain, and by how much emissions reductions would impact mission-critical initiatives (exhibit)."
