Introduction

The burning of fossil fuels has produced large greenhouse gas emissions. These gases, the principal of which is CO2, trap heat in the atmosphere; this drives climate change and its associated challenges, including global warming, drought, and flooding. Climate change mitigation involves reducing emissions of GHGs and removing the gases from the atmosphere. Carbon sequestration is one of the methods by which this can be achieved; by understanding this natural means of carbon dioxide storage, it can be enhanced in order to better remove CO2 from the atmosphere and bring the planet back from the brink of a climate crisis.

What is carbon sequestration?

Carbon sequestration is the storage of atmospheric carbon dioxide in carbon pools, such as the ocean and terrestrial ecosystems. It is a naturally occurring activity that is driven by biological, chemical, and physical processes.

What are the various methods of carbon sequestration?

Carbon sequestration falls into three groups: geological, biological, and physical.
