Carbon credits are a vital tool in the fight against climate change, enabling companies and individuals to offset emissions through various strategies. These credits come in three main types: Reduction, Protection, and Removal, each with distinct focuses, impacts, and applications. This article explores these types, detailing how they work, their environmental benefits, and practical examples of their use. By understanding the differences, stakeholders can make informed decisions about which carbon credits align best with their sustainability goals, contributing to global efforts to reduce atmospheric CO2 levels.

Reduction Carbon Credits

Reduction carbon credits focus on cutting emissions at the source, allowing companies to sell unused emission allowances to others within compliance markets. This approach targets direct emission reductions, such as through energy efficiency improvements or emission trading schemes like the EU ETS. However, its long-term impact is limited—it may shift emissions rather than reduce them globally, as one company’s reduction can enable another’s emissions. For example, a factory might install energy-efficient machinery, lowering its emissions and selling the surplus allowances. While effective locally, this method doesn’t address the global carbon stock, making it a partial solution.

Protection Carbon Credits

Protection carbon credits aim to preserve natural carbon sinks—like forests, wetlands, and oceans—that absorb CO2, preventing new emissions through conservation. These credits support projects such as forest protection initiatives or marine conservation efforts, which maintain ecosystems’ ability to sequester carbon. They offer moderate benefits by safeguarding existing carbon stocks; for instance, protecting a forest prevents deforestation that would release stored CO2. Web data shows that forest conservation projects offset 200 million tons of CO2e in 2024, per Verra. However, their impact is limited to prevention, not actively reducing atmospheric carbon, making them a complementary strategy.

Removal Carbon Credits

Removal carbon credits involve extracting CO2 directly from the atmosphere and storing it through natural or technological means, delivering high impact by actively reducing atmospheric carbon levels. Common examples include direct air capture (DAC), carbon capture and storage (CCS), and large-scale reforestation. For instance, DAC technology removes CO2 and stores it underground, while reforestation absorbs CO2 as trees grow—global reforestation efforts absorbed 150 million tons of CO2e in 2024, per the Global Forest Watch. This method addresses the root issue by lowering total CO2, making it a powerful tool for long-term climate mitigation.

Carbon credits play a crucial role in climate strategies, with Reduction, Protection, and Removal types offering distinct approaches. Reduction credits cut emissions at the source but may shift them elsewhere, offering limited global impact. Protection credits preserve carbon sinks like forests, moderately preventing new emissions. Removal credits, through methods like direct air capture and reforestation, actively reduce atmospheric CO2, delivering the highest impact. Understanding these types helps stakeholders choose the right credits for their goals, balancing immediate reductions with long-term carbon removal to drive meaningful progress in the global fight against climate change.
