Even if every person, company and country stopped emitting carbon tomorrow, the Earth’s temperature would continue to rise for years because of all the GHGs that have already been released. To ensure global temperatures remain within a safe range, it’s increasingly clear that carbon removal solutions need to play a much larger role in GHG reduction.
It’s estimated that, by mid-century, around 10 gigatonnes of carbon dioxide needs to be removed from the atmosphere each year. That will require a massive scale-up of carbon removal solutions. (It’s important to distinguish between carbon removal and carbon capture. Removal is the extraction of carbon dioxide that is already in the atmosphere, while capture is associated with preventing carbon dioxide from entering the atmosphere by intercepting it at the industrial source.)
Canada is emerging as a leader in this space with 40 organizations working on carbon removal initiatives. The suite of technologies, many still in the testing phase, includes highly engineered approaches, such as direct air capture (DAC), sequestering carbon in building materials and the production of biochar using pyrolysis, as well as solutions aimed at increasing the absorptive capacity of oceans, rivers and even mine tailings.
