Energy consumption, structural transformation and related carbon dioxide emissions of rural households on the Tibetan plateau

The use of solid fuels presents a dual challenge for rural household energy systems: transitioning to cleaner energy sources while reducing carbon dioxide (CO2) emissions. Particularly in the Tibetan Plateau (TP), which is highly sensitive to global climate change, addressing rural household energy consumption, structural changes, and related CO2 emissions is crucial for implementing targeted measures. Based on household-level survey data, this study analyzes the quantitative and structural changes in energy consumption patterns among rural households on the TP from 2001 to 2021, as well as their related CO2 emissions. The results indicate that: (1) Yak dung is the primary fuel for rural households on the TP and a major contributor to direct household emissions. (2) While cooking has shifted considerably towards a modern clean energy structure, heating continues to rely on solid fuels such as firewood, yak dung, and coal. (3) Commercial energy used by high-income groups for agriculture, transportation, and other purposes has resulted in an overall increase in total household energy consumption and related CO2 emissions. Policymakers must implement more effective measures to accelerate the transition to cleaner, modern energy sources for heating and cooking purposes.
