War and military intervention are damaging to the wider environment and the communities that rely on these environments. Concrete blast walls have become a major weapon in modern battlefield for protection against explosions and to restrict the movement of insurgents. However, the environmental and social impacts of their production and use remain under the research and policy radar as there are no frameworks for monitoring and reporting such scope III military emissions. We examined the extent of concrete wall used in Baghdad, the embodied carbon and socio-economic impacts on the populace using life cycle analysis techniques and content analysis of existing literature on the socio-economic effects. The concrete slaps littered in Baghdad altered the urban fabric, restricted movement of people and vehicles and increased economic hardships. The embodied carbon of these walls amounts to about 199 thousand tonnes C02e which is comparable with the carbon emissions from 43,282 average sized passenger vehicles on the road for one year. We recommend that robust framework for reporting military emissions be spelt out by the United Framework Convention on Climate Change and emissions included in national inventories.
