What does decarbonising mining look like?
We know reducing carbon emissions is important—but how are mine sites around the world taking steps to shrink their carbon footprint?
Let's take action
With ambitious 2050 decarbonisation goals, many companies have 2030 target marks to see if they’re on track. What are companies doing now to ready the critical minerals needed for the energy transition, reduce carbon emissions, replace conventional energy sources, and remove carbon from the atmosphere?

Carbon in plants
Remote sensing—via planes, drones, and satellites—offers a quicker, less costly way to count the benefits of carbon sequestration.
Carbon Sequestration and Remote Monitoring
N/A
Mining companies can remove carbon from the atmosphere through carbon capture technologies, carbon sinks or sequestration. Natural resource-based industries can utilise land for storing carbon in both plants and soil. Remote sensing—via planes, drones, and satellites—offers a quick way to measure carbon sequestration in vegetation.
