Additionally, many methods are still being developed and not yet scaled up to tackle the magnitude of the problem. The main way to slow climate change is an obvious one: Stop releasing greenhouse gas emissions. Emissions reduction strategies decrease the release of greenhouse gases into the atmosphere from a specific activity or across a certain area. According to a 2013 [study](https://www.nature.com/articles/nclimate2009) supported by the National Institute of Environmental Health Sciences, reducing emissions could help prevent millions of premature deaths brought on by air pollution[ during the following century.](https://www.niehs.nih.gov/research/programs/geh/geh%5Fnewsletter/2013/12/spotlight/reducing%5Fgreenhouse%5Fgas%5Femissions%5Fcan%5Fimprove%5Fair%5Fquality%5Fand%5Fsave%5Flives%5F.cfm) Reducing carbon emissions not only improves overall air quality and safeguards human health—it is absolutely essential in the fight against climate change. Beyond the reduction of emissions (ultimately achieved by ending the use of fossil fuels), there are a few other ways to reduce the amount of carbon in our atmosphere. But there are a lot of similar sounding terms thrown about in this space. Here’s what you need to know. ## **Carbon Dioxide Removal** Carbon dioxide removal (CDR) involves taking this greenhouse gas out of the atmosphere and storing it underground or under the ocean floor, ideally for a very long time. There are both nature-based and technology-based approaches to CDR. The two main strategies for removing carbon from the atmosphere are tree planting and forest restoration or conservation efforts, and direct air capture (DAC), according to a World Resources Institute report released in 2020\. Trees have been[ one of the best CDR](https://www.edf.org/article/carbon-capture-fight-climate-change-stop-climate-pollution) tactics for thousands of years because of their ability to sequester and store carbon as long as they stay standing. Earth’s forests have a net absorption of [7.6 billion metric tons annually](https://www.wri.org/insights/forests-absorb-twice-much-carbon-they-emit-each-year), which represents about one-third of annual global emissions. DAC, on the other hand, vacuums carbon dioxide out of the air. ## **Direct Air Capture** DAC facilities use giant fans to suck carbon dioxide out of the atmosphere and either store it underground in geological formations, or reuse it (like for synthetic fuel and concrete). [Carbon Engineering](https://carbonengineering.com/) in Canada and [Climeworks in Switzerland](https://climeworks.com/) are two examples of companies developing this type of technology. Climeworks has built the world’s largest DAC plant in Iceland, which began operating in 2021\. The facility, known as Orca, is capable of capturing 4,000 metric tons of carbon annually (equivalent to the emissions produced from 504 homes’ energy use in one year) and pumping it underground where, when mixed with water, the gas will cool and turn into stone. There are currently [19 DAC facilities](https://www.iea.org/reports/direct-air-capture) operating around the world. The International Energy Agency states that an average of 32 large-scale plants need to be built annually between now and 2050 to reach global climate goals. ## **Carbon Sequestration** Carbon sequestration refers to how—through biological, chemical, and physical processes—carbon dioxide is naturally removed from the atmosphere and locked away in the planet’s soils, oceans, trees, and rocks. For instance, as a tree grows,[ photosynthesis captures carbon dioxide](https://www.edf.org/article/carbon-capture-fight-climate-change-stop-climate-pollution) from the atmosphere and stores it in the trunk, branches, leaves, and roots. Carbon sequestration, however, also has its limitations. For instance, deforestation, wildfires, and other disturbances to the world’s woodlands cause around 8 billion metric tons of CO2 trapped in trees to be lost, [according to the Environmental Defense Fund](https://www.edf.org/article/carbon-capture-fight-climate-change-stop-climate-pollution). This is why strategies to slow climate change often involve an emphasis on stopping deforestation, restoring cleared areas, and enabling damaged woods to regrow. Other limitations exist, as well. Global warming is already reducing the ocean’s ability to absorb carbon. Additionally, carbon sequestration requires farmers to not till or plow their fields, disturbing the soil, because carbon dioxide that has been[ stored in the soil may be released back into the atmosphere, defeating the original purpose of keeping carbon dioxide out of the atmosphere.](https://envirobites.org/2019/03/08/keeping-carbon-in-the-ground/) A shift to regenerative agriculture is occurring in some places of the world, which emphasizes the importance of soil health and adopting different practices so as to not disturb it. ## **Negative Emissions Technology** Carbon removal technologies are also referred to as negative emissions technologies (NETs). The potential of NETs to[ rapidly remove](https://www.eesi.org/articles/view/carbon-removal-strategies-a-broad-overview#:~:text=One%20major%20benefit%20is%20the,generating%20economic%20growth%20and%20jobs.) carbon dioxide on a massive scale is one key advantage in comparison to natural systems, which are slower to absorb carbon and sometimes face external threats (like wildfires). However, while large-scale NETs are considered critical to meeting ambitious international climate change targets, these technologies still largely remain in the research and development phase, or are not yet scaled up. Facilities built so far remove just a tiny fraction of the carbon dioxide that scientists say is necessary to make a difference. But governments are getting behind these efforts. The [U.S. Department of Energy announced in May 2022 that it would provide $3.5 billion](https://www.energy.gov/articles/biden-administration-launches-35-billion-program-capture-carbon-pollution-air-0) to groups developing direct air capture and related technologies. In addition, the U.K.’s Department for Business, Energy, and Industrial Strategy announced in July 2022 the equivalent of a $64 million investment in carbon removal technologies. ## **Carbon Capture and Storage** A close cousin to both carbon dioxide removal and carbon sequestration is carbon capture and storage (CCS), which involves, for example, capturing CO2 from point sources, like a coal plant’s smokestack, and then permanently storing it underground or under the ocean floor; in fact, the [International Energy Agency](https://www.iea.org/reports/the-role-of-co2-storage) predicts that CCS could be responsible for removing as much as 20% of total CO2 emissions from industrial and energy production facilities. Removing carbon as soon as it is burned and either storing it underground or using it to improve oil and gas recovery is a more common and fully established approach than direct air capture. But the implementation of commercial-scale CCS is costly, which creates a big barrier to widespread use. Additionally, “the deployment of CCS has been hindered by uncertainty in geologic storage capacities and sustainable injection rates,” according to the [scientific journal _PNAS_](https://www.pnas.org/doi/full/10.1073/pnas.1115347109). Other reports note the problem of[ leakage](https://www.frontiersin.org/articles/10.3389/fenrg.2018.00040/full) of CO2 from stored carbon. ## **Carbon Stock Protection** Then there’s the approach of carbon stock protection, which separates forest areas that should be preserved as[ High Carbon Stock (HCS) and High Conservation Value (HCV)](https://highcarbonstock.org/protecting-high-carbon-stocks-and-high-conservation-values-in-palm-oil-complementary-or-competing-approaches/) from degraded lands with low carbon and[ biodiversity benefits that could be developed](https://highcarbonstock.org/#:~:text=The%20High%20Carbon%20Stock%20Approach&text=The%20High%20Carbon%20Stock%20%28HCS,values%20that%20may%20be%20developed.). In the context of wildlife survival and reducing carbon emissions, restoration efforts should strive to reduce net emissions of greenhouse gasses, maximize the capacity of habitats to store and reduce pollution, and[ preserve and enhance biodiversity.](https://www.eea.europa.eu/publications/carbon-stocks-and-sequestration-rates) _This article is part of a series on key topics in the climate crisis for_ [_time.com_](https://time.com/) _and CO2.com, a division of TIME that helps companies reduce their impact on the planet.
