This can incorporate the addition of biochar (charcoal produced from biomass) to soils, where the carbon can remain stored for hundreds or thousands of years.
Other nature-based solutions include restoration of coastal and marine habitats to ensure they continue to draw CO 2 from the air.Įnhanced natural processes include land management approaches to increase the carbon content in soil through modern farming methods. These involve the repurposing of land use by growing forests where there was none before (afforestation) or re-establishing a forest where there was one in the past (reforestation). Nature-based solutions include afforestation and reforestation. There are multiple ways of removing CO 2 from the atmosphere, most of which fall into three broad categories: (1) nature-based solutions, (2) measures that aim to enhance natural processes, and (3) technology-based solutions. What is the difference between carbon neutral and carbon negative? In the Intergovernmental Panel on Climate Change (IPCC) Special Report on Global Warming of 1.5☌, published in late 2018, almost all the pathways analysed by the authors relied to some extent on carbon removal approaches in order to achieve net negative emissions after 2050. Meeting ambitious international climate goals may require global CO 2 emissions to fall below zero in the second half of this century, achieving what is known as net negative emissions.
Becoming carbon negative requires a company, sector or country to remove more CO 2 from the atmosphere than it emits. This is a significant commitment from an individual company, and it underscores the potential for approaches using negative emissions, or carbon dioxide removal, to play an important role in meeting international climate goals.Ĭarbon neutrality, or “net zero,” means that any CO 2 released into the atmosphere from human activity is balanced by an equivalent amount being removed. What’s more, the company said that by 2050, it plans to have removed from the atmosphere all the carbon that it has emitted since it was founded in 1975.
Microsoft recently announced that it aims to become carbon negative by 2030.
