Summary of the Discussion Paper: Opportunities for Mitigating the Environmental Impact of Energy Use in the Middle East and North Africa (MENA) Region

Core Content

This paper discusses the opportunities for reducing the environmental impact of energy use in the Middle East and North Africa (MENA) region, focusing on greenhouse gas (GHG) emissions and particulate matter (PM) concentrations. It presents an analysis of energy efficiency improvements and their potential to reduce emissions and pollution levels across different sectors and countries in the region.

Main Objectives

• To analyze the links between energy efficiency and GHG emissions and urban air pollution in the MENA region.
• To create scenarios of emissions reduction under different energy efficiency improvement assumptions.
• To identify the country/sectors where energy efficiency improvements are most impactful.
• To benchmark the MENA region against other regions in terms of energy and GHG intensity.

Key Findings

1. GHG Emissions and Fossil Fuel Use

• The MENA region accounts for 5% of global GHG emissions in 2005, with Iran being the largest emitter, contributing 27% of the region's total emissions.
• The region's total GHG emissions are half of those in Asia (excluding China).
• The energy sector is the largest contributor to GHG emissions, accounting for 44% of total emissions in the region.
• The transportation sector contributes 22% of emissions, similar to the world average, while the industry sector contributes 20%.
• Most MENA countries rely heavily on oil and natural gas, with coal contributing minimally to emissions.

2. CO₂ Emissions by Fuel Type

• Oil contributes over 50% of CO₂ emissions in most MENA countries, with Yemen relying entirely on oil.
• Natural gas accounts for 39% of the region’s total CO₂ emissions, while coal contributes just 3%.
• The UAE and Iran have the highest CO₂ emissions from fossil fuels.

3. CO₂ Emissions by Sector

• The transportation sector is the largest consumer of total final energy, accounting for 31% of total final consumption (TFC), which is higher than the world average.
• The industry sector accounts for 25% of TFC, comparable to the world average.
• The energy sector is the largest emitter, contributing 44% of the region's CO₂ emissions.

4. Decomposition Analysis

• The decomposition analysis shows that energy efficiency improvements in the energy and other sectors have the highest potential to reduce CO₂ emissions.
• A 10% improvement in energy efficiency in the energy and other sectors could reduce total CO₂ emissions by 4–8%, with Israel achieving the highest reduction of 8.05%.
• A 10% improvement in the transportation sector could reduce total CO₂ emissions by 1–3.5%, with Iraq having the highest reduction of 3.5%.
• A 10% improvement in the manufacturing sector could reduce total CO₂ emissions by 1–3%, with the UAE achieving the highest reduction of 2.86%.

5. PM Concentrations and Damage Costs

• The MENA region has 90 μg/m³ of PM concentrations, which is 50% higher than the world average.
• Iraq has the highest PM concentration at 167 μg/m³, followed by Egypt, Kuwait, Oman, Libya, UAE, and Saudi Arabia.
• PM damage costs in the region are equivalent to 0.9% of the 2004 GNI, which is 1.8 times the world average.
• Iraq and Kuwait have the highest PM damage costs at 2.7% of GNI.
• Energy efficiency improvements in oil, diesel, and coal consumption can reduce PM concentrations by 7.8%, with Iraq achieving the highest absolute reduction.

6. Cross-Country Regression Analysis

• GDP per capita is the most significant factor in determining energy consumption and CO₂ emissions per capita.
• Other factors such as sectoral composition, hydrocarbon production, and energy prices also play a role.
• The analysis shows that MENA has high energy and CO₂ intensity in the manufacturing sector.
• The UAE has the highest energy and CO₂ intensity in the manufacturing and residential sectors.
• Due to data limitations, the paper is unable to confirm whether MENA is relatively energy-intensive when controlling for all other factors.

Conclusion

• Energy efficiency is a critical tool for reducing both GHG emissions and urban air pollution in the MENA region.
• The UAE and Iran are the most energy-intensive countries, with significant potential for energy efficiency improvements.
• The manufacturing and residential sectors in the UAE are the most energy and pollution-intensive and offer the greatest potential for emissions reduction.
• The transportation sector, while contributing a moderate share of emissions, also has potential for improvements.
• The study highlights the need for targeted energy efficiency policies in the MENA region to address environmental and economic challenges.
