Hey fellow impactful ninja ?

You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.

  • Most of these links are informational-based for you to check out their primary sources with one click.

  • But some of these links are so-called "affiliate links" to products that we recommend.

Why do we add these product links?

First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.

And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.

What do these affiliate links mean for you?
  1. First, and most importantly, we still only recommend products that we believe add value for you.

  2. When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.

  3. And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.

What do these affiliate links mean for us?
  1. When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.

  2. When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).

  3. And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.

What does this mean for me personally?

You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.

Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

Stay impactful,

Carbon capture and storage (CCS) practices store carbon dioxide (CO2) in various natural reservoirs. Partnered with carbon offsets, CCS could play a crucial role in mitigating climate change. So, we had to ask: what are the best carbon capture and storage offsets?

The best carbon capture and storage offsets are offered by Climeworks, The Arbor Day Foundation, REDD.plus, SeaTrees, and Husk, which offer direct carbon/air capture, reforestation, afforestation, REDD+, blue carbon, carbon mineralization, and agricultural carbon offset projects.

Keep reading to learn more about the best carbon offsets for carbon capture and storage, how these carbon offset projects work, what their respective offsetting costs are, and what your best way would be to offset your carbon emissions. At the end of the article, we’ll also share with you what the biggest carbon offsetting limitations are and why reducing your carbon footprint is more effective than offsetting it.

Here’s What All the Best Carbon Capture and Storage Offsets Have in Common

Carbon offsets are reductions in carbon emissions that are used to compensate for carbon emissions occurring elsewhere. They are measured in tons of carbon dioxide (CO2) equivalents and are bought and sold through international brokers, online retailers, and trading platforms on what is known as the global carbon offset market. 

Carbon Offset: a way for a company or person to reduce the level of carbon dioxide for which they are responsible by paying money to a company that works to reduce the total amount produced in the world, for example by reforestation”

Oxford Dictionary

Carbon capture and storage (CCS) is the combination of two processes, CO2 capture and long-term CO2 storage in various reservoirs to minimize its effect on the atmosphere.

Carbon Capture and Storage: the process of trapping carbon dioxide produced by burning fossil fuels or other chemical or biological processes and storing it in such a way that it is unable to affect the atmosphere, with the aim of mitigating the effects of global warming.” 

Oxford Languages

CCS can occur via two main methods:

  • Artificial methods: The result of carbon capture. The captured carbon is compressed into a liquid and transported via pipeline, ship, or tanker before being pumped deep underground, often at depths of 1 kilometer (0.6 miles), and sequestered in depleted oil reserves, coalbeds, or saline aquifers. 

Carbon Sink: a forest, ocean, or other natural environment viewed in terms of its ability to absorb carbon dioxide from the atmosphere.

Oxford Dictionary 

CCS is also commonly referred to as carbon sequestration because carbon sequestration is the next step after CO2 has been captured.

Some of the most common CCS offset projects include:

How Effective and Efficient Are Carbon Capture and Storage Offsets

In terms of effectiveness, carbon capture and storage (CCS) offsets can permanently remove carbon from the atmosphere, can remove emissions quickly, and can reinforce our carbon sinks, depending on the type of capture and storage. However, they do not reduce your own carbon emissions, which can lead to greenwashing.

In terms of efficiency, CCS offsets can be cost-effective, can continue to avoid carbon emissions after their project lifespan, and have low rates of carbon re-emission, depending on the type of capture and storage. However, they may also lack permanence, and may not yet be scaled to compensate for our global emissions. 

CCS offsets are effective at mitigating climate change because:

However, CCS offsets can also lack effectiveness because they do not reduce your own carbon emissions, which can lead to greenwashing. This occurs when emissions are only offset and not reduced from the source, and the consumer is deceived into thinking they are offsetting their emissions but in reality, they are not.

CCS offsets are efficient at reducing CO2 emissions because:

  • Reforestation, afforestation, REDD+, blue carbon, and agricultural offsets are some of the most cost-effective methods of carbon emission reduction, averaging less than $50 per ton of CO2 offset. 
  • Trees continue absorbing carbon long after they mature, which means reforestation, afforestation, and mangrove blue carbon projects can continue to reduce carbon emissions long after the trees have been planted.
  • DCC/DAC offsets can have low rates of carbon re-emission when plants are operated by low-carbon electricity. And carbon mineralization offsets store carbon permanently, even if rocks are broken.

However, CCS offsets can also lack efficiency because:

What Are The 6 Pros and 6 Cons of Carbon Capture and Storage Offsets

Carbon capture and storage (CCS) offsets can be permanent, immediate, cost-effective, have low rates of carbon re-emission, and reinforce our carbon sinks depending on the specific type of offset. They also allow us to reduce carbon emissions in ways we wouldn’t be able to accomplish individually.

However, CCS offsets can lack permanence, can be relatively expensive, may not be scaled to compensate for our global emissions, can negatively alter ecosystems, and can be difficult to standardize, verify, and monitor, depending on the specific type of offset. They also do not reduce your own carbon emissions, which can lead to greenwashing.

#6: Carbon capture and storage offsets do not reduce your own carbon emissionsIf emissions are only offset and not reduced from the source, this could lead to greenwashing, when the consumer is deceived into thinking they are offsetting their emissions but in reality, they are not. 

How Can Carbon Capture and Storage Offsets Help Mitigate Climate Change

Climate change is a severe and long-term consequence of fossil fuel combustion. Carbon capture and storage (CCS) offsets can help mitigate climate change because they eliminate fossil-fuel-derived carbon from our atmosphere which, if left untreated, can remain there for tens of thousands of years and exacerbate the negative effects of climate change.

How is Climate Change Defined

Climate change is arguably the most severe, long-term global impact of fossil fuel combustion. Every year, approximately 33 billion tons (bt) of CO2 are emitted from burning fossil fuels. The carbon found in fossil fuels reacts with oxygen in the air to produce CO2

Climate change: changes in the earth’s weather, including changes in temperature, wind patterns and rainfall, especially the increase in the temperature of the earth’s atmosphere that is caused by the increase of particular gasses, especially carbon dioxide.

Oxford Dictionary

Atmospheric CO2 fuels climate change, which results in global warming. When CO2 and other air pollutants absorb sunlight and solar radiation in the atmosphere, it traps the heat and acts as an insulator for the planet. Since the Industrial Revolution, Earth’s temperature has risen a little more than 1 degree Celsius (C), or 2 degrees Fahrenheit (F). Between 1880-1980 the global temperature rose by 0.07C every 10 years. This rate has more than doubled since 1981, with a current global annual temperature rise of 0.18C, or 0.32F, for every 10 years. 

As outlined in the 2015 Paris Climate Agreement, we must cut current GHG emissions by 50% by 2030 and reach net zero by 2050

How Do Carbon Offsets Generally Help Mitigate Climate Change

Levels of carbon in our atmosphere that cause climate change have increased due to human emissions since the beginning of the Industrial Revolution in 1750. The global average concentration of carbon dioxide in the atmosphere today registers at over 400 parts per million. Carbon offsets can help prevent these levels from increasing even more.

When you hear the words “carbon offset”, think about the term “compensation”. Essentially, carbon offsets are reductions in GHG emissions that are used to compensate for emissions occurring elsewhere

Carbon offsets that meet key criteria and verified project standards, are additional and permanent, and are a part of projects that are carried out until the end of their lifespan have the best chance of reducing carbon emissions and therefore reducing climate change. 

When we offset CO2 we also slow the rate of global temperature rise, which in turn minimizes the effects of climate change. 

How Do Carbon Capture and Storage Offsets Specifically Help Mitigate Climate Change

Carbon capture and storage in general can specifically help mitigate climate change because it eliminates atmospheric carbon, which when emitted, can remain in our atmosphere for a long period of time

Reforestation, afforestation, and REDD+ offsets specifically help mitigate climate change because they plant more trees, and trees remove CO2 from the air as they grow. By increasing the number of trees on our planet, we increase the amount of carbon they are capable of storing. The more carbon our forests can absorb, the less carbon there is in our atmosphere. 

Blue carbon offsets specifically help mitigate climate change because they protect coastal and marine ecosystems, which are capable of absorbing more CO2 per acre than rainforests and at a rate 10x greater. 

Direct carbon/air capture and carbon mineralization offsets specifically help mitigate climate change because these methods permanently lock away CO2 for thousands of years with little to no re-emission.

Agricultural carbon offsets such as biochar, agroforestry, avoided grassland conversion, and CH4 capture can specifically help mitigate climate change because they reduce CO2 and CH4 emissions in one of the biggest industries worldwide.

Final Thoughts

Climeworks, The Arbor Day Foundation, REDD.plus, SeaTrees, and Husk are the best carbon capture and storage (CCS) offsets. Ecologi, One Tree Planted, The Ocean Foundation, Wildlife Works, Neustark, greenSand, and Vi Agroforestry also offer projects involving reforestation, afforestation, REDD+, blue carbon, carbon mineralization, direct carbon/air capture, and agriculture. Lastly, Terrapass offers a variety of CCS offsets for both individuals and businesses.

CCS offsets facilitate the long-term storage of carbon in various natural reservoirs. But for all of the good carbon offsets can instigate, they should not be seen as the only solution to climate change. They are effective at reducing CO2 in the short term, but in the long term, they fail to reduce CO2 enough. 

When used in conjunction with direct CO2 reduction measures, carbon offsetting can be much more effective. We should reduce our own carbon footprint as much as possible first, and only then choose the most effective CCS offsets.

Stay impactful,
