+Introduction
+------------
+The GEIDCO IV project aims to design and develop two contrasting scenarios: a Business-as-Usual (BAU) scenario and the Global Energy Interconnection (GEI) 1.5°C scenario. 
+Under the GEI 1.5°C scenario, the project analyzes global and regional pathways toward carbon peaking and carbon neutrality. 
+This includes a detailed assessment of energy demand across regions, sub-sectors, and energy types, with a particular focus on end-use sectors such as industry, transport, and buildings.
+
+A key component of the project is the comprehensive life cycle assessment of core technologies in the new power system, including photovoltaics, wind power, hydro power, ultra-high voltage (UHV) transmission, and energy storage. 
+The study quantifies carbon emissions, energy consumption, and key resource requirements for these technologies at the end-use level. 
+Furthermore, by integrating the GEI carbon neutrality scenario, the project estimates global installed capacities for photovoltaics, wind power, hydro power, UHV transmission expansion, and energy storage deployment. 
+This enables an in-depth evaluation of the carbon and resource footprints of these technologies while considering the geographic distribution of critical resources needed for achieving global carbon neutrality.
