The Yemen completed its TNA process in 2024 as part of the TNA IV project. It has decided its priority sectors and technologies for both mitigation and adaptation. Over the past years, the country assessed barriers and identified measures for priority technologies. Yemen successfully completed its TNA in 2024.
Yemen’s water resources, agricultural sector and coastal zones are highly impacted by climate change. Climate change-related impacts on the country include, among others, changes in the rainfall patterns that are triggering drought, extreme flooding and an increase in storm frequencies and severity. The country is exposed to pests and sudden disease outbreaks, as well as rises in sea level.
Such climate change-related hazards are a major concern, especially since the country’s economy is largely dependent on the natural resources of its rural areas, where more than 75% of the population lives. Engaged in farming and pastoralism activities, the rural population is therefore highly reliant on favourable climatic conditions for their livelihoods.
Yemen’s NDC sets out a goal of a 1% reduction in GHG emissions by 2030 compared to a business as usual scenario and an additional 13% reduction achievable under certain conditions, which would bring the total GHG reductions to 14% below business as usual emissions levels by 2030. In its NDC, the country focuses on energy efficiency, renewables, fuel switching, nuclear power, and carbon capture and storage.
The Barrier Analysis revealed institutional capacity constraints; financial constraints; geographic and social diversity as major impediments, however following the TNA there are already projects aligned with TNA priorities: water‑management, agriculture resilience interventions, rehabilitating irrigation canals, restoring farmland, improving water supply and sanitation, and deploying renewable energy, solar systems even in critical infrastructure like hospitals.
Prioritised Technologies for Mitigation & Adaptation
The TNA identified and ranked the top 4 technologies per priority sector for Yemen:
| Sector | Ranked Priority Technologies |
| Mitigation – Energy | 1. LED lighting 2. Off‑grid and on‑grid solar PV systems 3. Wind turbines 4. Solar water heating Technology Needs Assessment+1 |
| Mitigation – Transport | 1. Bus Rapid Transit (BRT) 2. Improving by‑roads (road infrastructure) 3. Hybrid vehicles 4. (also natural‑gas or improved‑efficiency vehicles implied) Technology Needs Assessment+2Technology Needs Assessment+2 |
| Adaptation – Water | 1. Saline‑water desalination 2. Rainwater harvesting 3. Diversion facilities & channels 4. Wastewater recycling / reuse UNFCCC+1 |
| Adaptation – Agriculture | 1. Irrigation‑saving techniques 2. Water‑harvesting & storage for agriculture 3. Agricultural soil management & conservation 4. Reuse of treated wastewater / greywater |
