Carbon emissions are the de facto currency of climate change, yet many companies struggle to quantify carbon emissions, especially in the supply chain.

Our researchers work with industry and stakeholders to develop and implement new methods to track and reduce carbon emissions across the supply chain. Two of our areas of focus, freight transportation and metals & minerals, are detailed below.

Do you have a question about your carbon footprint? Contact us at to learn more about how you can get involved.

Freight Transportation

What’s the climate impact of planes, trains, ships and trucks? 

MIT CTL works with companies to implement the GLEC Framework to improve transparency in freight supply chain carbon emissions. Our research helps companies establish a baseline carbon footprint for logistics activities, develop science-based climate targets, and create tangible strategies for tracking and reducing carbon emissions in collaboration with suppliers.

Metals & Minerals

How do we account for the climate impact of metals and minerals?

Metals and minerals are a key part of every day products as well as technology crucial to climate change mitigation – renewable energy technology and electric vehicles. We are building a new carbon accounting framework specific to metals and minerals that will connect end users with minerals producers, increasing transparency on carbon emissions along the supply chain.
