Maersk’s ambition to reaching net-zero
Global supply chains connect the world, keep economies running and choreograph the movement of goods and services that are essential to our way of life. They are also responsible for around 11% of global greenhouse gas (GHG) emissions.
As a key player in global logistics, Maersk is taking purposeful action to reach net-zero GHG emissions across our operations—to the benefit of our customers and society while reducing transition risks for our business and shareholders.
This large and complex challenge has many critical external dependencies. Therefore, our energy transition is an ongoing learning exercise and we continue to learn and adapt - always with our decarbonisation targets as an end-goal. Our approach is to decisively act and invest in areas we control, as outlined in our transition plan, while driving stakeholder engagement and advocating for progress in areas with external dependencies.

In 2024, Maersk became the first in our industry to set validated GHG emission targets, based on the Science Based Targets initiative’s (SBTi) new Maritime Guidance. Our commitment is to reach net-zero GHG emissions by 2040 from a 2022 base year, with key mid-term targets for 2030. The targets include specific and absolute targets to reduce emissions from Maersk’s own operations and across our supply chains.
Priorities and actions on climate change
To make our decarbonisation commitment a reality, Maersk focuses on providing innovative, low emissions logistics solutions to our customers, building scale and momentum. We invest in low emission fuels and technologies where we see supply chain decarbonisation opportunities such as batteries, electric trucks and barges, network planning software, and information sharing technology. We also work closely with regulators and other stakeholders to build robust policies that support our sector’s energy transition and accelerate and scale decarbonisation efforts.
Explore Maersk’s decarbonisation progress and priorities in our businesses:
2025 emissions
- Efficiency improvements in Ocean network and assets, including the implementation of the Gemini network, vessel retrofitting and voyage optimization, were not sufficient to offset the need for rerouting vessels around the Cape of Good Hope and increased air cargo transportation emissions.
- Increased sales of marine fuels and containers to third parties and taking delivery of 10 new dual-fuel methanol vessels led to a substantial increase in scope 3 (value chain) emissions.
- On the positive side, network and asset efficiency efforts helped keep 2025 scope 1 emissions consistent with 2024, despite a larger fleet. Scope 2 (purchased energy) emissions fell by 12% for the year due to our energy switch to renewables at sites including Morocco and Bahrain.
The largest opportunity to reduce emissions remains global regulations to close the price gap between traditional fossil fuels and low emission fuels, derisk investments, and allow this nascent market to scale. The energy transition of our industry is a difficult task, and we expect it to continue to be challenging going forward.

Climate related risks
As a global company, many Maersk operations are located in areas with risk exposure to the impacts of climate change. In 2025, Maersk conducted a climate risk assessment to evaluate physical impacts on land-based assets and operations covering more than 1,400 own and third-party assets (terminals, warehouses, offices, and data centers), to identify exposure to hazards such as flooding, storm surge, windstorms, heatwaves, and water stress.

Regulatory drivers
Regulatory debates also continue to impact our sector, as consensus and action on several topics critical to the energy transition remain elusive. While there has been promising regional progress in climate policy, more ambitious and impactful policies are urgently needed at a global level to add scale, derisk investments and avoid a patchwork of local policies which add complexity.
Maersk is committed to conducting all our policy outreach in alignment with the Science-Based Targets initiative (SBTi) goal of limiting global temperature rise to 1.5°C. We actively engage with policymakers and stakeholders to advocate for regulations and policies that support this crucial objective, ensuring our business strategies are in harmony with global mitigation efforts.
