What does a Removal Unit (RMU) represent under the Kyoto Protocol?

A Removal Unit (RMU) under the Kyoto Protocol specifically represents one metric ton of greenhouse gas (GHG) reduction. This term comes from the context of carbon accounting and the efforts aimed at mitigating climate change by reducing emissions. The Kyoto Protocol established mechanisms for countries to create, trade, and bank RMUs as a way to meet their individual emissions reduction targets.

The correct choice highlights the importance of quantifying emissions reductions in measurable units, facilitating transparent tracking and trading of credits between countries. This approach enables nations to achieve their commitments under the Protocol by investing in projects that sequester carbon, leading to verified reductions in atmospheric GHG concentrations. Thus, the focus is on the tangible outcome of greenhouse gas reduction, which is a critical component of international climate policy.
