Publication: Keys to Energy-Efficient Shipping

Abstract

This report quantifies the extent to which energy efficiency measures can reduce greenhouse gas (GHG) emissions and fuel costs in global shipping. Drawing on a fleet-wide analysis across key vessel segments (bulk carriers, container ships, and tankers), it assesses the untapped potential of technical and operational efficiency measures through to 2050. Findings show that maximizing energy efficiency can cut global shipping’s GHG emissions by up to about 40% by 2030, exceeding current IMO interim targets, while simultaneously lowering the costs of the energy transition. Roughly half of these potential GHG savings by 2030 pay for themselves, offering savings of up to $220 billion annually in total costs as green fuel supply chains develop, and helping to build resiliency against fuel price volatility and rerouting shocks. The report highlights the role of short-term operational measures (such as forms of port call and speed optimization) and medium-term technical innovations (for example, wind-assisted propulsion) in achieving substantial efficiency gains. It identifies persistent economic, behavioral, and organizational barriers to uptake and illustrates them through deep dives on port call optimization and wind-assisted propulsion, showcasing innovative industry initiatives being applied to overcome these barriers. Finally, the report offers targeted recommendations for policymakers, industry, ports, and financiers to accelerate the adoption of energy efficiency solutions at scale.

Power More With Less: Scaling Up Energy Efficiency for Growth and Energy Security

Energy efficiency is a transformative, low-cost solution that can fast-track access to affordable and secure energy and boost economic growth. Amid soaring power demand, driven in part by air conditioners, heavy industry, and, increasingly, data centers needed to power artificial intelligence, energy efficiency can help countries avoid overspending on new energy infrastructure, importing fuels, and taking on more debt for their energy sectors.

2025 Global Gas Flaring Tracker Report

Highlights

  • In 2024, flaring surged by 3 billion cubic meters (bcm) to 151bcm, the highest level since 2007. The top nine flaring countries continue to account for three-quarters of all flaring, but less than half of global oil production.
  • More than half a billion people still lack reliable access to electricity. The associated gas wastefully burned each year is equivalent to Africa’s total annual gas consumption.
  • 389 million tonnes of carbon dioxide equivalent (MMtCO2e) emissions, including 46 MMtCO2e in the form of unburnt methane, were released by flares in 2024.


The latest Global Gas Flaring Tracker, an independent report of gas flaring worldwide, reveals that global gas flaring volumes rose to 151 bcm in 2024 from 148 bcm in 2023. This is the highest level since 2007. Flaring Intensity, the amount of flaring per barrel of oil produced, has remained largely unchanged in the last fifteen years.

The top nine flaring countries continue to account for three-quarters of all flaring, but less than half of global oil production. If captured and used, the gas flared could have helped provide energy for some of the world’s most energy-deprived people.

The increase in gas flaring in 2024 highlights the need for oil producers to rapidly accelerate efforts to end routine flaring and minimize pollution from oil and gas operations. The World Bank’s Global Flaring and Methane Reduction (GFMR) Partnership estimates that in 2024 flaring released 389 million tonnes of CO2e, with a significant portion in the form of unburnt methane.

The report highlights that countries committed to the Zero Routine Flaring by 2030 (ZRF) initiative performed significantly better than countries that have not made the commitment. However, while some countries have made progress reducing flaring, the overall increase in 2024 underscored the need for governments and operators to prioritize flaring reduction projects.

The report calls on governments and operators to act now to end routine gas flaring and reduce methane emissions from oil and gas production.

The World Bank’s annual Global Gas Flaring Tracker is a tool for monitoring and understanding the state of flaring worldwide and the progress made towards achieving Zero Routine Flaring by 2030. GFMR, together with the Payne Institute at the Colorado School of Mines, has developed global gas flaring estimates based upon observations from a satellite launched in 2012 and operated by the U.S. National Oceanic and Atmospheric Administration. The advanced sensors of this satellite detect the heat emitted by gas flares as infrared emissions.

About GFMR

GFMR is a multi-donor trust fund supported by governments, companies, and multilateral organizations committed to ending routine gas flaring and reducing methane emissions from the oil and gas sector. GFMR provides catalytic grant funding, technical assistance, policy and regulatory reform advisory services, capacity building and institutional strengthening for methane and flaring reduction projects. For example, GFMR mobilized $11 million to detect and repair methane leaks in Uzbekistan’s gas distribution network. The project has already eliminated 9,000 tones of methane emissions per year, with further reductions of 100 thousand tonnes of methane emissions expected each year.

Tracking SDG 7 – The Energy Progress Report 2025

Highlights

  • In 2023, the number of new electricity connections outpaced population growth, increasing global access to electricity to 92%. While this means 19 million fewer people are without electricity compared to the previous year, 666 million people are still without power. In addition, this rate of growth is not fast enough to ensure universal access to electricity by 2030.
  • 85% of the world’s population without electricity lives in Sub-Saharan Africa, up from 50% in 2010. In 2023, 35 million people in this region got electricity, but due to population growth, the number of people without electricity only decreased by 5 million, from 570 million in 2022 to 565 million in 2023.
  • Most people without electricity live in remote areas, places facing conflict or violence, and low-income regions, making it hard to expand the electricity grid. However, new technologies and business models for decentralized renewable energy (DRE) – such as solar home systems and solar mini grids- offer flexible solutions for these areas. These solutions are expected to help over 561 million people worldwide in 2023, and they provided 55% of new electricity connections in Sub-Saharan Africa from 2020 to 2022.
