How Much Carbon Does a Tree Capture (24 Species + Calculator)

A man wearing a scientist’s lab coat holds up a measuring stick to a dark cloud of co2 gas that has an arrow pointing to a leafy green tree in a field to measure how much carbon does a tree capture.

With various claims about the benefits of trees on reducing and reversing climate change, you might be wondering, “How much carbon does a tree capture?”

Trees are nature’s best carbon capture technology and have been working to clean the air since the first leafy frond appeared on Earth, and research shows that they are one of the best tools the planet has (at the moment) to help mitigate climate change.

But, all trees aren’t the same…certain species can store more carbon than others. (Check out the eco-power of the 24 below!)

How Much Carbon Does a Tree Absorb? Find Out With This Tree Carbon Calculator

As natural carbon sinks (or carbon reservoirs), trees capture carbon dioxide (CO2) from the atmosphere as they grow, but the amount of CO2 captured by a tree depends on its size, it’s age, and other factors, like the tree’s species and where it is growing.1

The calculator above estimates the average lifetime carbon benefits of any tree, based on its size. And, it shows equivalents, so you can see just how beneficial a tree is to the planet.

It uses the most up-to-date information from academic research and USDA Forest Service11 databases but doesn’t differentiate by species… for that, you’ll need to check out the information below.

Forests are also critical to ecosystems, providing habitat for animals and plants, many of which are vital to survival. Forests also provide a range of environmental services most people take for granted. For example, they absorb storm water and reduce flooding, protect water quality by filtering out pollutants and sediment from waterways, and provide shade to cool the cities.

Calculating How Much Carbon Does a Tree Absorb: DIY Steps

The calculator above will help you determine how many trees you need to plant to offset your carbon footprint. Others can also allow you to compare the different types of trees and calculate how much carbon dioxide your favorite tree can capture in a year.6

If you’re planting trees to offset your carbon footprint, it helps to know which species absorb the most carbon. Some tree benefits calculators12 determine which tree species you can grow to contribute the most carbon capture.

Follow these steps:

  • Step 1: Determine whether you are using the calculator for a single tree or a group of trees to determine how much carbon a tree captures.
  • Step 2: Enter the trunk circumference (single tree) or the number of trees, and the approximate age of the tree(s).
  • Step 3: View calculation results immediately, including how much oxygen the trees produce, and how much carbon emissions they store.

How Is Carbon Sequestered by a Tree?

Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one approach to reducing the amount of climate change-causing carbon dioxide in the atmosphere. Trees are the largest living organisms on earth and use photosynthesis to sequester carbon from the atmosphere. The carbon they take in is stored in the tree’s fibers (roots and other areas) as it grows.

Just by growing up, a tree will sequester carbon over its lifetime. This process is called biological sequestration. Carbon sequestration is basically the retention of carbon dioxide (being stored) by some process (trees are very good at it) in order to help fight climate change and greenhouse gas impact on the planet.

Carbon Sequestration

Carbon sequestration13 is the natural or artificial removal of CO2 from the atmosphere and storage of it in solid or liquid form to mitigate climate change. Most forms of biological sequestration are long-term and involve storing large amounts of biomass for a long time.

Biomass can be stored underground (geological sequestration), underwater (ocean sequestration), or on land (terrestrial sequestration). Forests effectively retain carbon because their biomass consists of large amounts of woody material that persists for decades to centuries after being established.

Carbon Sequestering Through Photosynthesis

Carbon is sequestered by a tree when absorbed from the air during photosynthesis and stored as carbon in the wood.8 Carbon sequestration occurs very efficiently in trees, particularly those that live for a long time, such as coastal redwood trees. Trees store 50% to 75% of the carbon they take up from the atmosphere in their wood, and the rest is released back into the atmosphere during respiration.

Photosynthesis only occurs during sunlight hours and is more efficient in warmer weather. The amount of carbon sequestered depends on its species, size, and life stage. In addition to the carbon sequestered by a tree’s trunk, roots, branches, and leaves, additional carbon is stored in the soil when the tree sheds its leaves or branches.

The amount of carbon that a tree can sequester over its lifetime depends on its size, species, and location. For example, larger trees generally sequester more carbon than smaller trees of the same species because they have more space to store it. And trees growing near oceans or in wet climates tend to grow faster and sequester more carbon than trees growing inland or in dry climates.8

Importance of Plants in Carbon Capture

Trees and other plants pull some carbon dioxide out of the atmosphere and store it as carbon in their trunks and branches. Forests and other green spaces are essential to reducing carbon footprint. Forests are particularly effective at sequestering carbon because trees can live for hundreds of years.

This is why tree planting carbon offset programs can deliver real reductions in carbon footprint amounts, when purchased from the top carbon offset providers. Some providers will have a one-month carbon offset product which would allow individuals to offset their average carbon emissions in a month.

It’s not just trees that sequester carbon14 — plants do it too. Grasslands can be more efficient at storing carbon than forests if they’re managed properly. For example, when grazing lands are managed using techniques like rotational grazing (where livestock move periodically, so the grasses have time to recover), these grasses can sequester more carbon than some forests.

What Happens When Trees Die?

Some carbon is released back into the atmosphere when trees die or are cut down unless it stays trapped in wood products such as lumber or paper. If trees are burned for fuel or left to decompose naturally, their stored carbon will become part of atmospheric CO2 and contribute to global warming for centuries or even thousands of years.

When a tree dies, most of its carbon is not released back into the atmosphere as CO2 but remains stored in forest soils, peat bogs, and wetlands, making forests an essential tool in reducing greenhouse gas emissions from fossil fuels. However, if trees are harvested and processed into long-lasting wood products such as lumber or pulp for paper, the dead tree will keep its stored carbon out of the atmosphere.7

If you build your home out of wood instead of steel and concrete, your home will hold that carbon until it eventually decomposes back into the soil as part of a forest ecosystem.

Which Tree Absorbs the Most CO2?

Several trees absorb CO2 more than others, with some types of trees absorbing enormous amounts. Some species have specific qualities that make them better at absorbing CO2. For example, some have a longer lifespan, and some grow faster than others. Mangrove trees are known for their high carbon sequestration abilities, as well as other marshy tree systems that have their roots based in waterways.

However, due to their lifespan and size, the Giant Sequoia tree takes the prize for storing the most carbon emissions during it’s life.

How Much Carbon Does a Tree Capture? By Species

When you think of trees, you probably think about their importance to the environment. But which trees absorb the most carbon dioxide, and what role do they play in our environment? While it is inevitable that all trees have an essential role in absorbing carbon dioxide, there are some more effective than others.

An acre of trees can sequester17 about two to five tons of carbon dioxide each year.

How Much Carbon Does One Tree Offset?

Although the general rule is about 120-150 pounds of carbon sequestration by a single tree, this total varies widely depending on what type of tree it is and where it’s located.

Maple trees absorb about 22 pounds of carbon dioxide each year.

Does Forest Management Matter?

Forests provide more than just protection from natural disasters and carbon sequestration. They protect water quality, provide habitat for wildlife, clean the air and give us a place to hike, bike, hunt, and fish.

Forest management is the process by which humans control and care for forests. You can use the Species Calculator to help you find out how much carbon a tree captures, based on it’s size, and it will help you in forest management.

Forest management18 is the practice of maintaining forests through harvesting, planting, and replanting. There are many things to consider in forest management, including what trees should be planted and who should regulate these efforts.

You can also participate in efforts to use trees for carbon capture as part of a comprehensive strategy for addressing climate change.

Planting Trees in Places Where They Never Existed Before

Forest management is designed to ensure that afforestation programs consider the risks of planting trees where no trees existed before. The new trees will not have any natural defenses against pests or fires. In addition, they will not provide shelter for wildlife species such as birds or animals that live in the forest canopy.

This is why afforestation programs can be dangerous. When a species in introduced where it didn’t exist before, the risks of invasive dangers is magnified.

Different species of trees need to be planted in the right areas.  When planting trees where no trees existed before, one must consider the following factors;

  • Soil Type – Forests are only sustainable in certain soil types. Growing on the wrong kind of soil will result in plant death, harming the environment and being frustrating and costly for all involved.
  • Topography – Different species of trees thrive in different altitudes and topographical locations. Forest management ensures that afforestation programs consider other types of topography and plant accordingly.
  • Climate – Most tree species can survive without human assistance; however, they all need a specific environment to thrive. The environment needs to be considered when planting trees in different locations; otherwise, they will not flourish.
  • Wind Patterns – Wind is a natural occurrence that can help or harm growing forests depending on its direction and frequency. Forest management ensures afforestation programs take into account wind patterns and plant accordingly to ensure maximum plant survival rates.

Many environmentalists argue that planting only native species in their natural habitat is the way to help reduce climate change.

The Dangers of Replacing Old Growth Forests

You can avoid some pitfalls when replacing old-growth forests.19 The risks emanating from old-growth forests are complex and dynamic ecosystems. Therefore, replanting them can be challenging. It’s essential to consider diseases and pests, native species, soil conditions, trees’ capacity to re-establish in the area, the natural disturbance cycle, and how it can affect new growth.

The expectation that new forest plantations can maintain biodiversity and ecological functions at the same level as the old-growth forest is often unfounded. The arrival of new species is an essential part of old-growth forest dynamics. Frequent disturbances by fire and wind create gaps in the canopy, which allow small tree species to grow up and eventually replace the older trees.9

Plantations typically have a dense uniform canopy with no gaps, preventing understory vegetation development.

When replacing old-growth forests, there are a few dangers to avoid. The risks emanate from:

  • The soil is not healthy. The original forest may have removed the nutrients from the earth.
  • Invasive plants and animals replace the old-growth forest. These species may be toxic to the new trees you plant.
  • The new trees are susceptible to diseases. They will suffer more because they are not adapted to the environment they were placed in.

The only way to effectively replace forests that were cut and cleared is to use native seeds and species that have survived.

The Root of the Matter

One of the most important and transformative things you can do today is to understand how much carbon a tree captures; since trees are an excellent means of carbon capture, and if we start planting more trees and protecting our existing forests, we can make huge positive changes to the climate. So, how much carbon does a tree capture… plenty, if the trees are allowed to flourish and do the job nature intended.
