There are over 213 million businesses worldwide that help drive our global economy. But these businesses are also responsible for a large amount of carbon emissions that contribute to climate change. So, we had to ask: What are the best carbon offsets for medium & large businesses?

The best carbon offsets for medium and large businesses are Terrapass, Carbonfund, and Cool Effect. In addition, Climeworks is the most effective but also most expensive carbon offset option and Climate Vault locks away carbon permits from the compliance market.

Keep reading to learn more about the best carbon offsets for medium & large businesses, 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 Offsets for Medium & Large Businesses 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 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 planting trees”

Oxford Dictionary

When you purchase carbon offsets, it’s important that they actually make a difference in total carbon emissions. To achieve that, the following are key criteria:

• Carbon offset projects have to be effective (different projects have different effectiveness rates)
• Carbon offset projects have to be additional
• Carbon offset projects have to be permanent
• The claims from carbon offset projects have to be verifiable

(For a full overview, check out our guide on how to choose carbon offset projects that actually make a difference.)

Carbon offset costs: The business side of Climeworks is a B2B operation where costs may be evaluated after personal contact. 

How to get your carbon offsets: To learn how Climeworks B2B solutions could help your business with its climate goals, contact their sales team.

Climate Vault: Locking Away CO₂ Emissions For Good

Climate Vault is an organization that works with supporters, organizations, and individuals to reduce and eliminate carbon footprints. They participate in the mandatory carbon market, also known as the cap-and-trade market. Their mission is to reduce CO₂ emissions significantly while also continuing to support technology that can remove CO₂ already in the atmosphere.

“Make net zero a reality, right now”

Climate Vault

Project overview: Climate Vault has taken a different approach to reduce CO₂ emissions. First, they purchase carbon permits issued to businesses on the cap-and-trade compliance market. Then, they store them in their vault so that emitters cannot use them. Since the number of carbon permits is finite, this decreases the overall amount of CO₂ that emitters are allowed to emit. 1 permit translates to 1 metric ton (1,000kg) of CO₂ vaulted, making their approach easily measurable and verifiable. 

Carbon offset costs: The business side of Climate Vault is a B2B operation where costs are determined after contacting a Climate Vault team member.  

How to get your carbon offsets: Contact the Climate Vault team to inquire about offsetting your business.

How to Choose Carbon Offset Projects Actually Make a Difference

The following information is a summary for you based on our full guide: “How to Buy Carbon Offsets That Actually Make a Difference”

Purchase carbon offset projects with high effectiveness rates. The offset programs in order of most to least effective are:

• Direct CO₂ removal: Machines remove CO₂ directly from the air. Effective at reducing emissions in the short and long-term because they are additional and permanent.
• Renewable energy: Investing in projects that build and maintain renewable energy sites globally. There is no additionality because renewables are becoming a greater share of our energy mix, with or without the help of offsets.
• Energy efficiency improvements: The creation of products or systems that use less energy than conventional systems to perform the same task. However, if products are replaced too quickly, the amount of CO₂ required to produce the new product would exceed the amount of CO₂ saved with the new product.
• Carbon sequestration: The long-term storage of carbon via forestry practices. Not an effective way to reduce emissions in the long-term because there is no guaranteed permanence.

If – and only if – they are both additional and permanent, carbon offsets can help reduce your overall GHG emissions to balance off your personal carbon footprint to fight climate change – at least in the short term. But they can be much more effective if they meet certain key criteria and project standards.

Here are key criteria to look for in a carbon offset program:

• A clearly defined protocol that determines which types of projects are eligible and how emission reductions will be measured

• Independent third-party verification of compliance with the protocol

• Registration of offsets in an offset registry, which tracks each credit with a unique serial number to ensure it is only used once 

• Transparency in project implementation and reporting 

If used correctly, carbon offsets can provide environmental, economic, and social benefits that go beyond reducing carbon emissions. They have the potential to instigate meaningful environmental change and begin to reverse some of the effects of climate change. 

Carbon offset project standards assure transparency and quality in the creation, quantification, and verification of offset projects. This way you can ensure that the project is actually reducing CO₂ emissions. The following are recognized carbon offset standards:

• Verified Carbon Standard (VCS): Considered the world’s leading voluntary GHG program, with 1700+ projects having removed 630+ million tons of CO₂ from the atmosphere. Examples of projects include hydropower in Turkey, forest conservation in Peru, and landfill gas capture in China.

• Gold Standard: A certification that seeks to maximize every dollar of climate and development funding. It has issued 134 million carbon credits from 1700+ projects based in more than 80 different countries. Examples of projects include solar power in India, efficient cooking and heating in China, and wind power in Indonesia.

• Climate Action Reserve (CAR): The premier carbon offset registry for the North American carbon market having issued over 150 million offset credits since its inception in 2001. Examples of projects include landfill gas capture in South Carolina and forest management in California.

• American Carbon Registry (ACR): The first private voluntary GHG registry in the world. Examples of projects include ozone-depleting substances in Arkansas and methane capture from mines in Kentucky.

Choosing carbon offset projects from any of the above project standard registries helps ensure that your project is verified and that it actually reduces CO₂ emissions.

What Are the Biggest Carbon Offsetting Limitations

In fact, there are 9 main carbon offsetting limitations that can make the current voluntary carbon market controversial and lead to confusion, inconsistencies, and a general distrust of the system. Have a look at the quick summary table below.

Why Reducing Your Carbon Footprint Is More Effective Than Offsetting It

The main argument against carbon offsets is that they don’t really reduce overall emissions. Instead of substituting offsetting carbon emissions, we should instead cut the emissions directly at the source. Basically, if we stop emissions from getting into the atmosphere in the first place, we won’t have to worry about offsetting. But have we done this? Have we cut emissions directly at the source? The data says no.  

The COVID-19 pandemic triggered the largest decrease in energy-related carbon emissions since World War II, a decrease of 2 billion tons. However, emissions rebounded quickly at the end of 2020, with levels in December ending 60 million tons higher than those in December 2019. This indicates that the earth is still warming at an accelerated rate, and not enough is being done to implement clean energy practices. 

When you buy a carbon offset, you are paying someone else to cut their emissions so you don’t have to cut your own emissions. This is why offsetting alone will not be enough to reduce global carbon emissions.

Carbon offsets are a good place to start if you want to get into the carbon-emission reduction game, but in order to be effective in the long term, we must not rely on them solely. Cutting emissions from the source and then offsetting the remainder is the best way to reduce our carbon footprint and provide the highest environmental benefits. If we fail to cut emissions first, we will fill up our carbon sinks and render them unusable. Preventing carbon emissions rather than reacting once they are already emitted is the best way to reduce overall emissions.

Carbon offsets reduce GHG emissions from coal, oil, and natural gas. Reducing your consumption of these, in turn, reduces your carbon footprint, which has huge impacts on environmental, economic, and public health. A reduced carbon footprint due to lower GHG emissions can mitigate the effects of climate change, improve public health, boost the economy, and maintain plant and animal diversity.

• Climate change: Reducing your carbon footprint plays a role in mitigating the side effects of global climate change. The more we reduce the amount of GHG emissions, the more we slow the rate of temperature rise, sea-level rise, ice melting, and ocean acidification.

• Public health: Reducing GHG emissions lessens the likelihood and severity of extreme weather events, improves air and water quality, maintains biodiversity, and supports a healthy food supply.

• Economics: Reducing GHG boosts the economy, especially when it becomes economically rewarding to innovate solutions that help protect our planet, fight climate change, and are based on clean energy.

• Plant and animal diversity: Protecting biodiversity protects human health because many plants and animals are used in modern medicines

Carbon offsets have the potential to instigate meaningful environmental change, but to make the greatest impact we must understand both their benefits AND drawbacks. 

Final Thoughts

Carbonfund, Terrapass, Cool Effect, Clear, Ecologi, Cooler, 3Degrees, Climate Vault, Climeworks, Selectra have the best carbon offset options for medium and large businesses looking to reduce their carbon footprint. They either have specific programs for medium and large businesses or have a variety of options for these businesses to offset different aspects of their companies. They are third-party verified, permanent, additional, and use the leading carbon offset standards.

Overall, carbon offsets can help reduce your overall carbon emissions to balance off the carbon footprint of your business to fight climate change – at least in the short term. But in the long term, direct methods of carbon footprint reduction are much more effective. Reducing your business’ carbon footprint first before relying on carbon offsets can make more of a difference in the fight against climate change.
