To date there is no single, silver-bullet solution to removing carbon and other harmful greenhouse gases.
Large-scale carbon removal or negative-emissions technologies will be essential to reach the Paris 1.5C climate target. Today however, many are only just emerging and still have some limitations, including the time to scale and cost (1).
Equally, the most common carbon removal solution today - afforestation and reforestation - has well recognized limitations in its permanence and vulnerability to disturbance (2).
At Climate Responsible, we believe that a portfolio of carbon removal solutions is the most robust way to mitigate your business' carbon footprint, delivering impact across multiple immediacy and durability horizons.
Solutions we use
We have evaluated carbon removal technologies from providers across the globe to identify those that truly are carbon negative (including the carbon footprint of their operation) and that provide a durable, timely impact. You can find out more about what we look for in those evaluations here and the removal solution lifecycle analyses here.
Our Carbon Removal Certificates are build from engineered sequestration solutions including Direct Air Capture and Bio-Oil, Enhanced Weathering solutions, and natural sequestration through Mangrove Afforestation, all of which meet our acceptance criteria.
Removing Greenhouse Gases straight from the atmosphere
Reacting atmospheric CO2 with minerals
Turning organic waste into a liquid for underground storage
Planting and restoring mangrove ecosystems
We have selected this set of carbon removal solutions after analyzing numerous scientific studies and academic papers. No single solution is perfect, but we have found that portfolios combining these offer an optimal combination of effectiveness, scalability and - by varying the proportion of forestation - cost.
The best summary of the academic research is the 2018 study by the Royal Academy of Engineering, which compared seven of the most promising Negative Emission Technologies (carbon removal solutions) to assess their feasibility, effectiveness, and side-effects.
Innovation in carbon removal will be critical to long term climate management and we are constantly searching for new solutions to introduce to our portfolios. If you have a potential carbon removal solution you would like us to evaluate for inclusion in our CRC, please contact us with its LCA to discuss further.
