What is a carbon sink?

A carbon sink is anything that absorbs more carbon from the atmosphere than it releases – for example, plants, the ocean and soil. In contrast, a carbon source is anything that releases more carbon into…

Carbon sink

A carbon sink is anything, natural or otherwise, that accumulates and stores some carbon-containing chemical compound for an indefinite period and thereby removes carbon dioxide (CO2) from the atmosphere. Globally, the two most important carbon…

The Ocean, a carbon sink

A carbon sink is a natural or artificial reservoir that absorbs and stores the atmosphere’s carbon with physical and biological mechanisms. Coal, oil, natural gases, methane hydrate and limestone are all examples of carbon sinks.…

Carbon conservation and sequestration in ocean

Many coastal blue carbon ecosystems have been recently lost or badly degraded. There is a need to improve protection and consider restoration wherever practicable, through the design of novel and smart, cross-sectorial and multi-regulatory responses.


Could removing carbon from the ocean be a climate change solution?

By Rosanna Xia   04/13/23  
The ocean, after all, has long been a silent hero when it comes to climate change. It has absorbed almost one-third of the carbon dioxide released by humans since the Industrial Revolution — and more…

Why helping whales to flourish can help fight climate change

By Corinne Purtill   02/07/23  
The ocean is one of the planet’s great carbon sinks, absorbing nearly a third of the atmosphere’s greenhouse gas emissions. Swimming in its depths are the great whales, a population whose sheer physical mass allows…
