Definition

Composite index which measures an economy’s position within global liner shipping networks. It is calculated from the number of ship calls, the container handling capacity of ports, the number of services and companies, the size of the largest ship, and the number of countries connected through direct liner shipping services. For each year, the value of the fourth quarter is considered.

Methodology

The composite index is calculated from the number of ship calls, the container handling capacity of ports, the number of regular liner services, the number of companies, the size of the largest ship, and the number of countries connected through direct liner shipping services. For each component, the country’s value is divided by the average value for the component in Q1 2023 and then is calculated the average of the six components for the country. The average across components for a given country and quarter is then multiplied by 100. The result is an average LSCI of 100 in Q1 2023. This scaling was applied in March 2024 for the whole series (from Q1 2006). This is a change from the previous calculation methodology where components and index were scaled to the maximum value in Q1 2006.

Definition

Composite index which measures perceptions of a country's logistics based on the efficiency of customs clearance process, quality of trade- and transport-related infrastructure, ease of arranging competitively priced shipments, quality of logistics services, ability to track and trace consignments, and frequency with which shipments reach the consignee within the scheduled time. The index ranges from 1 to 5, with a higher score representing better performance.

Methodology

The indicator presents data from Logistics Performance Surveys conducted by the World Bank in partnership with academic and international institutions and private companies and individuals engaged in international logistics. The Logistic performance index (LPI) uses a structured online survey of logistics professionals at multinational freight forwarders and the main express carriers. Each survey respondent rates eight overseas markets on six core components of logistics performance (the efficiency of customs and border management clearance, the quality of trade and transport infrastructure, the ease of arranging competitively priced shipments, the competence and quality of logistics services, the ability to track and trace consignments, and the frequency shipments reach consignees within scheduled or expected delivery times). The components are rated on a scale (lowest score to highest score) from 1 to 5. The eight countries are chosen based on the most important export and import markets of the country where the respondent is located, on random selection, and - for landlocked countries - on neighboring countries that form part of the land bridge connecting them with international markets. The method used to select the group of countries rated by each respondent varies by the characteristics of the country where the respondent is located. If respondents did not provide information for all six components, interpolation is used to fill in missing values. The missing values are replaced with the country mean response for each question, adjusted by the respondent's average deviation from the country mean in the answered questions. The LPI is constructed from the six indicators using principal component analysis (PCA), a standard statistical technique used to reduce the dimensionality of a dataset. In the LPI, the inputs for PCA are country scores the questions covering the main six components, averaged across all respondents providing data on a given overseas market. Scores are normalized by subtracting the sample mean and dividing by the standard deviation before conducting PCA. The output from PCA is a single indicator - the LPI - that is a weighted average of those scores. The weights are chosen to maximize the percentage of variation in the LPI's original six indicators.

Methodology

Data are derived from the International Energy Agency (IEA) World energy balances, with additional information at https://www.iea.org/reports/sdg7-data-and-projections; and from the United Nations Energy Statistics Database (http://data.un.org/Explorer.aspx?d=EDATA); both providing a breakdown of national energy flows by products over time. The indicator is calculated as the ratio of final energy consumption from renewables after allocation of electricity and heat (AFECREN) to total final energy consumption (TFEC), calculated from the flows in the energy balances. Final consumption of electricity and heat is allocated to renewables based on the share of the gross generation coming from renewable sources. In practice, this occurs by calculating the percentage of electricity and heat produced by each renewable source, multiplying the final energy consumption of electricity and heat by those shares, and then allocating the resulting quantities to each renewable energy source’s final consumption. For instance, if total final consumption table reports 150 TJ for biogas energy, while total final consumption of electricity is 400 TJ and heat 100 TJ, and the share of biogas in total electricity output is 10 percent and 5 percent in heat, the total reported number for biogas consumption will be 195 TJ (150 TJ+400TJ*10%+100TJ*5%). As a result of this method, it is implicitly assumed that energy losses between energy supplied and energy consumed are proportional to their shares in production across all technologies. Total final energy consumption represents the sum of the energy from all sources used in the industry, transport, buildings, and other sectors of final consumption. It is derived from the national energy balance and excludes quantities used for non-energy purposes.
