The Global Warming Potential of Building Materials: An Application of Life Cycle Analysis in Nepal

Traditional buildings in Sagarmatha National Park and Buffer Zone, Nepal, release significantly lower greenhouse gas emissions compared to semimodern and modern structures. A life-cycle assessment revealed that traditional buildings emit about one-fourth of the emissions of semimodern buildings and less than one-fifth of those from modern buildings per square meter of wall. While modern buildings with thermal insulation reduce long-term energy consumption for heating, their initial global warming potential remains higher due to commercial material use. Over 25 years, traditional buildings emit 20% more greenhouse gases than modern ones, underscoring the environmental benefits of using local materials like wood and stone. This study highlights the potential for reducing emissions in construction by prioritizing locally sourced materials.
