As we stand in 2025, the urgency to implement effective carbon removal solutions has never been greater.
Understanding Carbon Removal: A Game-Changing Approach
Carbon removal, also known as carbon dioxide removal (CDR) or carbon sequestration, is the process of capturing CO2 from the atmosphere and storing it securely for long periods. This approach is essential because even if we halted all carbon emissions today, existing atmospheric CO2 levels would continue driving climate change for decades.
The Science Behind Carbon Removal
Carbon removal mimics and accelerates natural processes that have regulated Earth's carbon cycle for millions of years. Modern technologies have supercharged these processes, enabling carbon removal at rates that can meaningfully impact our climate crisis.
Carbon removal methods fall into two main categories:
Natural Solutions:
- Reforestation and afforestation
- Soil carbon sequestration
- Ocean-based carbon capture
- Enhanced weathering
Engineered Solutions:
- Direct Air Capture (DAC)
- Bioenergy with Carbon Capture and Storage (BECCS)
- Mineralization
- Biochar production
Experts agree that a diverse portfolio of these strategies will be necessary to achieve global climate goals.

Challenges and Controversies in Carbon Removal
Despite its promise, the carbon removal industry faces several challenges and criticisms:
Scalability and Cost
While carbon removal technologies have advanced rapidly, scaling them to the levels required to make a significant impact on climate change remains a formidable challenge. The Intergovernmental Panel on Climate Change (IPCC) estimates that we need to remove 10 billion tons of CO2 annually by 2050 to limit global warming to 1.5°C. Current global capacity is less than 1% of this target.
Critics argue that the focus on carbon removal may divert resources from emissions reduction efforts. A study published in Nature Climate Change suggests that for every dollar invested in carbon removal, at least ten dollars should be invested in emissions reduction to maintain a balanced approach.
Energy Requirements
Some carbon removal methods, particularly engineered solutions like DAC, require substantial energy inputs. A 2024 study by the International Energy Agency (IEA) found that scaling DAC to remove 1 billion tons of CO2 annually would require approximately 10% of global renewable energy production.
Environmental and Social Impacts
Large-scale deployment of certain carbon removal strategies, such as afforestation or BECCS, could compete with food production and natural ecosystems for land use. A report by the World Resources Institute estimates that dedicating 25% of global cropland to BECCS could threaten food security for up to 1 billion people.
Verification and Permanence
Ensuring the long-term storage of removed carbon and accurately measuring the impact of carbon removal projects remain ongoing challenges. The development of the ISO 14068 standard for carbon neutrality has helped, but implementation and verification across diverse projects and geographies remain complex.
The Path Forward: Integrating Carbon Removal into Climate Strategy
As we look beyond 2025, it's clear that carbon removal will play an increasingly vital role in our global climate strategy. However, it's crucial to emphasize that carbon removal is not a silver bullet or a replacement for aggressive emissions reductions.
