what are nature-based solutions?
Nature plays a dual role as a source of emissions and as a natural carbon sink. For these reasons nature can play a critical role in climate mitigation strategies.
Action must be taken to eliminate deforestation and to halt nature loss. At the same time, protecting, restoring and enhancing ecosystems can improve the ability to withdraw carbon from the atmosphere.
Companies in all sectors can catalyse action that preserves or enhances existing carbon stocks as part of an effort to compensate emissions as they transition toward a state of net zero emissions.
Nature-based Solutions (NBS) work with and enhance nature to help achieve Greenhouse Gas Removal. NBS prevents climate change impacts while slowing further warming.
Types of Nature-based Solutions
Growing new trees and improving the management of existing forests. As forests grow they absorb CO2 from the atmosphere and store it in living biomass, dead organic matter and soils.
Companies with land-use intensive business models (e.g. due to consumption or production of agricultural commodities) should aim to eliminate deforestation from their supply chains.
Restoration of peatlands and coastal wetlands to increase their ability to store carbon. This also prevents carbon release through further degradation, often providing a number of other co-benefits.
Applying nutrients to the ocean to increase photosynthesis and remove atmospheric CO2.
Increasing ocean concentration of ions like calcium to increase uptake of CO2 into the ocean, and reverse acidification.
Enhanced terrestrial weathering
Ground silicate rocks spread on agricultural land react with CO2 to remove it from the atmosphere.
Incorporating partially-burnt biomass into soils. Biomass is grown and burned in the absence of oxygen (pyrolysis) to create a charcoal-like product which can stabilise organic matter when added to the soil. Biochar can be produced by a range of existing technologies, including pyrolysis, gasification and hydrothermal carbonisation.
Soil carbon sequestration
Changing agricultural practices such as tillage or crop rotations to increase the soil carbon content.
ggr removal technologies
There are various types of Greenhouse Gas Removal (GGR) technologies which recapture already emitted greenhouse gases from the atmosphere and ocean.
Nature-based Solutions (NBS) work with and enhance nature to help achieve Green House Gas Removal. These solutions prevent climate change impacts while slowing further warming.
The Need for Collaboration
Innovation depends on collaboration, often between unlikely partners, and it often involves the adaptation and application of technologies from other industries.
