PPPs in Colombia: Policy Lessons

PPPs in Colombia: Policy Lessons

Latin American countries have introduced private participation in the transport sector to decrease the economic resources spent in projects’ time line. This private participation has also increased the development of corridors in which governments have taken more presence, allowing trade, either at the regional or international market level. However, the path followed by those countries has involved adjustments in regulations, laws, policies, risk management, financing, and guarantees. Read Book Chapter

The Life Cycle Assessment of Jet Fuel Production and Consumption – A Methodology for Saudi Arabia’s Aviation Sector

The Life Cycle Assessment of Jet Fuel Production and Consumption – A Methodology for Saudi Arabia’s Aviation Sector

Life cycle assessment (LCA) is a comprehensive methodology that contributes to informed decision-making and addresses environmental challenges across different sectors. The methodology has significantly evolved from its first development by the Coca-Cola Company in 1969 to its standardization by the International Organization for Standardization. The flexibility of LCA in environmental impact assessments in various industries, activities, and products has enabled it to support sustainability goals and initiatives such as the Paris Agreement and the European Union’s circular economy action plan. Specifically, in the air transportation sector, LCA has been applied in specific case studies involving fuel options, combustion emissions, and aircraft technologies to reduce climate impacts and achieve net-zero targets. The International Civil Aviation Organization has also developed a methodology to evaluate life cycle greenhouse gas emissions for aviation fuels that aligns with the Carbon Offsetting and Reduction Scheme for International Aviation sustainability criteria.

Identifying Emerging Challenges and Priorities for Aviation Decarbonization

Identifying Emerging Challenges and Priorities for Aviation Decarbonization

Decarbonization of the aviation sector has emerged as a global concern because the sector contributes 2%-3% to total global greenhouse gas emissions. Thus, it is critical for us to understand the associated emerging challenges. We determine key research priorities for achieving effective and equitable net-zero aviation by examining journalistic reports from a research perspective. Furthermore, we adopt this approach because journalistic reports frequently shed light on emerging energy economics, policy and sustainability issues before they are thoroughly examined in the scholarly literature. Specifically, we first derive overarching themes by summarizing and categorizing the wide-ranging scope of recent media investigations of aviation decarbonization.

Worldwide intraregional and interregional air passenger traffic volume distribution

Worldwide intraregional and interregional air passenger traffic volume distribution

Aviation, like other transport modes, is essential for the economy; it facilitates business and trade, allows people to connect with different regions/cities, and generate tourism. Air traffic at the country or regional level is quite interesting by analyzing and comparing its relative contribution to the worldwide air transport volume of passengers, considering domestic and international transport. As a result, the impact and importance of aviation for passengers vary by geography, giving a better understanding of how regions concentrate passengers’ air traffic volume. It also provides a global overview of the development and concentration of future growth.

Worldwide Intraregional and Interregional Air Freight Traffic Volume Distribution

Worldwide Intraregional and Interregional Air Freight Traffic Volume Distribution

Freight by air does not comprise a significant share of the worldwide tonnage due to its cost compared to land (road and rail) and sea transport. However, air freight is important for commodities that either have high values or are time-sensitive. For instance, documents, perishable products, electronics, pharmaceuticals, or emergency shipments of spare parts are commonly shipped by air. Although the demand for air freight could have a more important role in landlocked countries or developing regions where land transport infrastructure is scarce, it is limited because of the imbalances between inbound and outbound flows. Consequently, considering freight traffic volume worldwide concentration and distribution among countries or regions is remarkable when compared with its relative contribution to the global freight volume.

Aircraft seating capacity designation by selected airlines in Europe, the Middle East, Africa, Asia/Pacific, North America, and Latin America

Aircraft seating capacity designation by selected airlines in Europe, the Middle East, Africa, Asia/Pacific, North America, and Latin America

Aircraft capacity utilization is one of the main factors in an airline’s productivity. It is also vital when analyzing both energy efficiency and greenhouse gas emissions (GHG) in the aviation sector per passenger. In fact, the energy consumption by passengers in aviation has enormous variations due to two main factors: a. the aircraft characteristics; and b. the occupancy rate—the maximum aircraft capacity used. Although airlines have different aircraft fleets with varying seating configurations, the aircraft are usually broken down into the following general categories: a. small narrowbody aircraft with 150 seats or less in a two-class configuration; b. large narrowbody aircraft with 151 seats or more in a two-class configuration; and c. widebody aircraft with a two-aisle configuration. In addition, flight length classification criteria can alter from one airline carrier to another with no global standard agreed on, but routes are typically categorized into long-, medium-, or short-haul; however, certain aircraft are well known as long-haul flight operators depending on the aircraft’s technical characteristics.

The Implementation of the Carbon Offsetting and Reduction Scheme for International Aviation and Its Challenges for Aviation

The Implementation of the Carbon Offsetting and Reduction Scheme for International Aviation and Its Challenges for Aviation

The aviation sector is a fast-growing industry that contributes significantly to greenhouse gas emissions and climate change. To address this issue, the International Civil Aviation Organization (ICAO) set aspirational emissions goals and introduced the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). CORSIA aims to cap carbon emissions from international flights by 2020 through the use of sustainable aviation fuels (SAFs) and other measures. The eligibility criteria for SAFs include a 10% reduction in greenhouse gas emissions compared to fossil fuels and compliance with sustainability criteria. However, challenges remain, such as the limited production capacity and higher cost of SAFs. CORSIA’s implementation is voluntary for participating states in the first phase but will become mandatory in the second phase. Increasing participation, ensuring the integrity of offset credits, and addressing technological and documentation challenges are essential for the successful implementation of CORSIA and the decarbonization of the aviation sector.
