Selected Climate Solutions that Mitigate Climate Change and Provide Co-benefits

There are many climate solutions that mitigate climate change and provide co-benefits, such as biochar, which can be placed in the soil to sequester carbon and enable it to grow more food. Given below is a list of selected climate solutions with co-benefits. This includes a list of 28 climate solutions in the Drawdown Lift Initiative by Project Drawdown. Launched in 2021, Drawdown Lift advances the evidence for and disseminates knowledge about climate solutions that boost well-being, strengthen resilience, and contribute to poverty alleviation in rural communities in Africa and South Asia.

In addition to mitigating climate change, implementing these solutions on a large scale will help people in developing countries adapt to climate change and mitigate additional major problems, such as the global food crisis and forced migration. As a result, implementing climate solutions with co-benefits can help reduce conflict and increase stability in developing countries. This is very important since human security experts have identified climate change as a security threat multiplier, and there is an urgent need to mitigate the other problems it is causing as well.

Given below are selected lists of climate solutions with co-benefits:

1) Four selected climate solutions that mitigate climate change and provide significant co-benefits:

a) A proven climate solution that removes carbon from the atmosphere generates considerable benefits and can be implemented on a global scale is biochar. This product is produced from biomass in an oxygen-limited environment and is already being produced by many organizations. Since producing biochar from biomass and incorporating it into the soil is an internationally recognized way of removing carbon from the atmosphere, substantial money can be earned by creating it. To view more information about biochar and the opportunity to implement it on a global scale, visit this webpage we created: Biochar Overview: What it is, its benefits and an opportunity to scale it globally

b) An innovative algae growing system that produces healthy food-grade oils on a substantial scale by Global Algae Innovations, which received a million-dollar Carbon Removal XPRIZE for this technology. This company calculates that their technology can be scaled up to produce enough healthy food-grade oil so that this oil can replace all the palm tree oil production, which would enable the areas containing these palm trees to be able to be returned to back to ecologically diverse rainforests. If this did occur, billions of tonnes of carbon dioxide would be captured yearly as these rainforests grew back.

c) Cactus farming can capture substantial carbon from the atmosphere while producing valuable products. There is already substantial cactus farming occurring in the world using different species of cacti, with several groups advocating for a large scale-up of this type of farming. For example, Regeneration International is promoting its Billion Agave Campaign to plant one billion agaves globally to draw down and store one billion tons of CO2. The International Center for Agricultural Research in Dry Areas (ICARDA) promotes the growing of spineless cactus pear (nicknamed the “green-gold”) as a source of fodder for livestock.

d) Bamboo rapidly sequesters carbon in biomass and soil and can thrive on degraded lands. Long-lived bamboo products can store carbon over time—video: Bamboo Harvesting and Manufacturing in a $100 Billion Industry. For more info, see Bamboo Production by Project Drawdown.

2) Shown at this link is a table of 19 selected solutions that mitigate climate change and provide co-benefits, which can be implemented in developing countries on a large scale: Selected Climate Solutions that Mitigate Climate Change and Provide Co-benefits.  This estimate includes solutions advocated by Project Drawdown through their Drawdown Lift initiative. The estimated impact of these solutions, if they were implemented globally, is in the range of 26 billion tonnes per year of CO2 reduced and/or sequestered. According to the Global Carbon Project, global CO2 emissions in 2022 were estimated to be about 40.6 billion tonnes annually. Therefore, if these climate solutions were implemented on a global scale, their impact would be very substantial.
