New report exploring the material flow of steel and potential for green steel in the shipping sector. This report looks to start a discussion around the non-fuel related GHG emissions in the maritime sector and actions that can be taken to reduce them, through e.g., using materials with lower embodied GHG emissions in shipbuilding and embedding circular economy principles into the vessel lifecycle, among others. Green steel and shipping looks at the material flow of steel in the shipping sector and explores some of the drivers and barriers to increase uptake of green steel in shipping.
