Engineered carbon removal (ECR) is crucial to achieving deep decarbonization by midcentury. It is a necessary complement to rapid emissions reductions and the transition to clean energy. The ECR working group convenes companies across the ECR value chain, including innovative engineered carbon removal startups, companies, and financiers. This working group is focused on direct air capture (DAC) and biomass with carbon removal and storage (BiCRS) solutions.
There is broad consensus that both urgent greenhouse gas emissions reductions as well as gigatons of carbon dioxide removal (CDR) will be needed to limit the rise in average global temperatures to below 2 degrees Celsius above preindustrial levels. In addition to the widespread deployment of nature-based removal solutions, new forms of engineered carbon removal (ECR) will also be necessary.
In the last several years, there has been rapid growth in public and private investment in ECR technologies, including direct air capture (DAC), biomass with carbon dioxide removal (BiCRS), enhanced rock weathering, and marine carbon dioxide removal (mCDR). Today, the rate of carbon being removed from the atmosphere through ECR is about four orders of magnitude lower than needed to meet climate goals, as most techniques are still in the pilot or demonstration phase of technological readiness.
A great deal of technological innovation, policy development, and private and public investment in carbon removal technologies has occurred over the past decade. However, to achieve the necessary 10,000-fold increase in annual ECR in the next 25–30 years, this momentum will need to grow exponentially.
The engineered carbon removal ecosystem: includes key components of the supply chain as well as important ecosystem forces. The operational supply chain excludes a “biomass feedstock” input into BiCRS because this working group is focused on shared infrastructure/resources between DAC and BiCRS. The ecosystem forces include key local, market, and government factors that will influence the long-term success of the ECR industry.
This factsheet reviews several types of engineered carbon removals, and each technology’s decarbonization potential. It also outlines the co-benefits of ECR, including job creation, investment opportunities, ecological protection, and improved air quality, among others.
Read the FactsheetThere is broad consensus that both aggressive greenhouse gas emissions reductions and gigatons of carbon dioxide removal (CDR) will be needed to limit the rise in average global temperatures to below 2 degrees C above preindustrial levels. In addition to widespread deployment of nature-based CDR solutions like reforestation and agricultural soil management, new forms of engineered carbon removal (ECR) will also be necessary. ECR offers several advantages, such as larger removal and scalability potential, greater durability, and more locational flexibility. This brief offers five policy recommendations focused on addressing the financial and market barriers to scaling this critical-path technology.
