Energy-efficiency carbon offsets avoid carbon dioxide (CO₂) emissions because they develop energy-efficient mechanisms, which use less energy to perform tasks. This can then mitigate climate change and have positive impacts on public health. So, we had to ask: What are energy-efficiency carbon offsets really, and could they help us mitigate climate change?

Energy-efficiency carbon offsets are a specific type of carbon offset that develop and improve systems requiring less energy to perform tasks. Energy-efficiency projects reduce CO₂ emissions immediately, strengthening our natural carbon sinks and aiding in the transition away from fossil fuels.

Keep reading to find out all about what energy-efficiency carbon offsets are, how they work, what their project life-cycle is, how effective they are, their pros and cons, and how they can help mitigate climate change.

The Big Picture of Energy-Efficiency Carbon Offsets

Carbon offsets play an important role in mitigating the effects of global climate change by reducing greenhouse gas (GHG) emissions beyond what we each can achieve through individual actions. Energy-efficiency carbon offsets are a specific type of carbon offset that upgrade conventional systems into ones that use less energy to perform the same task. 

What Are Energy-Efficiency Carbon Offsets

Carbon offsets are reductions in GHG emissions that are used to compensate for emissions occurring elsewhere. They are measured in tons of CO₂ equivalents and are bought and sold through international brokers, online retailers, and trading platforms.

Energy-efficiency carbon offsets are a specific type of carbon offset that upgrade conventional systems into ones that use less energy to perform the same task.

How Are Carbon Offsets Defined

Carbon offsets play a crucial role in reducing our carbon footprint, the amount of CO₂ emissions associated with an individual or an entity. 

“Carbon footprint: the amount of greenhouse gasses and specifically carbon dioxide emitted by something (such as a person’s activities or a product’s manufacture and transport) during a given period”

Merriam Webster

Basically, a carbon footprint is the amount of carbon emitted by an activity or an organization. This includes GHG emissions from fuel that we burn directly (e.g., heating a home and driving a car) and GHG emissions from manufacturing the products that we use (e.g., power plants, factories, and landfills). 

One way to reduce our carbon footprint is via the use of carbon offsets. These are reductions in GHG emissions that are measured in tons of CO₂ equivalents and are bought and sold through international brokers, online retailers, and trading platforms. 

“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 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 can range anywhere from a couple of hundred tons of CO₂ per program per year to thousands of tons of CO₂ per program per year. 

How Are Energy-Efficiency Carbon Offsets Defined

Energy efficiency describes products or systems that use less energy than conventional systems to perform the same task. Energy-efficiency carbon offsets are a specific type of carbon offset that upgrade conventional systems into energy-efficient ones. 

“Energy efficiency: the use of less energy to perform the same task or produce the same result.”

U.S. Department of Energy

Examples of energy-efficiency projects include: 

• Energy-efficient solutions for disadvantaged households
• Energy-efficient buildings use less energy to heat and cool
• Energy-efficient facilities use less energy to manufacture goods
• Energy-efficient transportation reduces fuel usage

How Do Energy-Efficiency Carbon Offsets Work

Energy-efficiency carbon offsets avoid CO₂ emissions because energy-efficient mechanisms use less energy. And because our energy is often generated by fossil fuels or in unsustainable ways, the less energy we use, the less carbon we emit.

Some of the most common energy-efficiency projects involve energy-efficient cookstoves, water filtration programs, and co-generation facilities. Overall, these projects save money, increase the resiliency of our power grid, positively impact public health, and mitigate climate change. 

How and When Do Energy-Efficiency Carbon Offsets Reduce Your Carbon Footprint

Upgrading to energy-efficient methods is one of the most meaningful ways you can help preserve the environment and combat global climate change. Energy efficiency avoids carbon emissions immediately and also provides numerous benefits in addition to climate change mitigation.

How Do Energy-Efficiency Carbon Offsets Reduce Your Carbon Footprint

Energy-efficiency offsets help eliminate CO₂ emissions from direct fossil fuel combustion and from indirect electricity generation. By using energy-efficient appliances and methodologies, we reduce the amount of CO₂ entering our atmosphere. 

When Do Energy-Efficiency Carbon Offsets Reduce Your Carbon Footprint

Energy-efficient mechanisms begin reducing CO₂ emissions immediately upon installation or implementation because they use less energy to perform tasks. Avoiding carbon emissions immediately also leads to immediate reductions in atmospheric carbon and climate change mitigation.

What Could Prevent Energy-Efficiency Carbon Offsets From Being Realized

To be beneficial, energy-efficiency offsets must be additional, meaning that carbon emissions reductions would not have occurred without intervention. But energy-efficiency projects are often not additional because many projects receiving revenue now would have been built regardless. The large demand for energy-efficient practices, in general, means that the infrastructure could have been built independently of energy-efficiency carbon offsets. 

Also, centralized solutions are easier to keep track of by nature. But energy-efficiency solutions are decentralized, whereby power is generated at or near locations where it will be used. Therefore, there are different standards for different types of energy-efficiency practices. Appliances, lighting, buildings, cooking, and fuels are held to different standards, making it difficult to standardize energy efficiency as a singular entity. 

What Is the Project Life-Cycle of Energy-Efficiency Carbon Offsets

To fully understand reforestation offsets, we must assess each stage of its life cycle. This life-cycle assessment (LCA) is a method to evaluate the environmental impacts of products and materials. Over the years, companies have strategically used LCA to research and create more sustainable products. So, we had a look at the LCA for reforestation offsets! 

Building of Energy-Efficiency Carbon Offsets

CO₂ emissions at the building stage occur upon the construction of the energy-efficiency technology and transportation of the technology to various project sites.

Many components are required to construct energy-efficiency mechanisms, and building these components requires machinery that emits CO₂. For example, there are many different types of cookstoves (e.g., griddle, rocket, forced-air, gasifier) that all have different components. Water filtration systems, cookstoves, and co-generation facilities also all have a carbon footprint due to the construction and transportation of the technology to the project site.

Operating and Maintaining of Energy-Efficiency Carbon Offsets

There are very few CO₂ emissions or waste products associated with operating and maintaining energy-efficiency projects, making the carbon footprint of this phase low. 

CO₂ emissions at this stage are associated with the operation of the technology (e.g., water filters, cookstoves, and cogeneration facilities) at the project sites. And because these technologies use less energy to operate, they generally have a lower carbon footprint. For example, clean cookstoves can emit 50-80% less carbon than traditional wood-burning stoves. 

End-of-Life of Energy-Efficiency Carbon Offsets

The end-of-life of energy-efficiency offsets would include the end-of-life of the technology or anything that negates the project’s effectiveness.

The life expectancy of energy-efficiency solutions varies depending on the specific solution.

Therefore, water filtration systems, cookstoves, and waste cogeneration facilities would all have different lifespans. If properly maintained, these technologies are built to last.

It is also important to note that in order for energy-efficiency offsets to be effective, they must replace the formerly inefficient method, not just be an addition. For example, clean cookstoves projects can only avoid carbon emissions if people discontinue open-fire cooking. But in reality, many continue to cook over open fires as well as use clean cookstoves. This can actually lead to an increase in overall carbon emissions.

Tubeho Neza (“Live Well”): An Example Project of Energy-Efficiency Carbon Offsets

The Tubeho Neza (“Live Well”) project is a Rwandan clean cookstoves project. It was launched by DelAgua in 2013, in partnership with the Government of Rwanda, to transform the lives and environment of rural African communities. It is one of the largest programs of its kind which has helped avoid CO₂ emissions and pull families out of poverty.

To date, the project has provided over 6 million Rwandans with 1.3 million stoves, free of charge. The stoves use small twigs and branches, which people can collect without cutting down trees, using 71% less wood than a traditional fire and thereby reducing deforestation.

The Rwandan cookstoves project is certified by the Verified Carbon Standard and also adheres to multiple UN Sustainable Development Goals. You can visit DelAgua’s website and contact a representative to purchase your carbon offsets.

How Effective and Efficient Are Energy-Efficiency Carbon Offsets

In terms of effectiveness, energy-efficiency carbon offsets help reduce deforestation and strengthen our natural carbon sinks, and bolster energy security to help transition away from fossil fuels. However, they can also lack additionality, and they do not reduce your own carbon emissions, which can lead to greenwashing.

In terms of efficiency, energy-efficiency carbon offsets avoid carbon emissions immediately, promote energy decentralization, and are relatively cost-effective. However, they can also lack standardization and monitoring.

Energy-efficiency carbon offsets are effective at mitigating climate change because they:

• Reduce the demand for wood fuels, thereby reducing deforestation and strengthening our natural carbon sinks
• Bolster energy security by providing reliable, affordable access to fuels and energy sources that emit less carbon than traditional fossil fuels

However, energy-efficiency carbon offsets can also lack effectiveness because they often lack additionality because many projects receiving revenue now would have been built regardless.

Energy-efficiency carbon offsets are efficient at reducing CO₂ emissions because they:

• Avoid carbon emissions immediately after installation of the technology
• Promote energy decentralization, whereby power is generated at or near locations where it will be used
• Are relatively cost-effective when compared to other methods of carbon emission reduction

However, energy-efficiency carbon offsets can also lack efficiency because they often lack standardization and monitoring due to them being a decentralized solution.

Also, energy-efficiency carbon offsets 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. This is why we should first reduce our emissions before relying on offsets.

How Could You Offset Your Own Carbon Footprint With Energy-Efficiency Carbon Offsets

The market for carbon offsets was small in the year 2000, but by 2010 it had already grown to represent nearly $10 billion worldwide. The voluntary carbon offset market (VCM) is where everyday consumers can purchase carbon offsets to offset their carbon emissions. 

The Ecosystem Marketplace predicts the VCM can grow to $50B by the year 2050. And because energy-efficiency carbon offsets are effective and efficient at reducing carbon emissions, they could make up an increasingly larger share of this market. Below are our favorite energy-efficiency offsets.

How Can Energy-Efficiency Carbon Offsets Help Mitigate Climate Change

Climate change is a severe and long-term consequence of fossil fuel combustion. Energy-efficiency carbon 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 as a result of 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 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 Energy-Efficiency Carbon Offsets Specifically Help Mitigate Climate Change

Energy-efficiency offsets help eliminate CO₂ emissions from direct fossil fuel combustion and from indirect electricity generation. By using energy-efficient appliances and methodologies, we reduce the amount of CO₂ entering our atmosphere. And because higher levels of atmospheric carbon exacerbate global warming, less is better.

What Are The 7 Pros and 3 Cons of Energy-Efficiency Carbon Offsets

Energy-efficiency carbon offsets avoid carbon emissions immediately, improve air quality, reduce deforestation and strengthen our natural carbon sinks, promote energy decentralization, bolster energy security and help transition away from fossil fuels, are relatively cost-effective, and allow us to reduce carbon emissions in ways we wouldn’t be able to accomplish individually.

Energy-efficiency carbon offsets can lack additionality, standardization, and monitoring, and they do not reduce your own carbon emissions which can lead to greenwashing.

What Are the 7 Pros of Energy-Efficiency Carbon Offsets

Energy-efficiency carbon offsets have various pros that make them effective at avoiding carbon emissions.

What Are the 3 Cons of Energy-Efficiency Carbon Offsets

Understanding the drawbacks of energy-efficiency carbon offsets is important in order to effectively mitigate climate change.

What Are Better Alternatives to Energy-Efficiency Carbon Offsets

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

However, we can’t let this method be a guilt-free way to reduce carbon emissions. Energy-efficiency offsets must be used in conjunction with direct carbon reduction measures so that we are directly reducing emissions as well as avoiding them.

These reduction measures don’t have to involve drastic changes either. Actions that may seem small can have a big impact because those small changes add up! You can reduce your carbon footprint in three main areas of your life: household, travel, and lifestyle. 

Reduce your household carbon footprint:

• Wash with cold water: Washing clothes in cold water could reduce carbon emissions by up to 11 million tons. Approximately 90% of the energy is used to heat the water, so switching to cold saves also saves energy.

• Replace incandescent bulbs with fluorescent bulbs: Fluorescent bulbs use 75% less energy than incandescent ones, saving energy and thus reducing electricity demand and GHG emissions.

Reduce your travel carbon footprint:

• Fly less: Aviation accounts for around 1.9% of global carbon emissions and 2.5% of CO₂. Air crafts run on jet gasoline, which is converted to CO₂ when burned.

• Walk or bike when possible: The most efficient ways of traveling are walking, bicycling, or taking the train. Using a bike instead of a car can reduce carbon emissions by 75%. These forms of transportation also provide lower levels of air pollution.

Reduce your lifestyle carbon footprint:

• Switch to renewable energy sources: The six most common types of renewable energy are solar, wind, hydro, tidal, geothermal, and biomass energy. They are a substitute for fossil fuels that can reduce the effects of global warming by limiting global carbon emissions and other pollutants.

• Recycle: Recycling uses less energy and deposits less waste in landfills. Less manufacturing and transportation energy costs means fewer carbon emissions generated. Less waste in landfills means less CH₄ is generated.

• Switch from single-use to sustainable products: Reusing products avoids resource extraction, reduces energy use, reduces waste generation, and can prevent littering.

• Eat less meat and dairy: Meat and dairy account for 14.5% of global GHG emissions, with beef and lamb being the most carbon-intensive. Globally, we consume much more meat than is considered sustainable, and switching to a vegan or vegetarian diet could reduce emissions. 

• Take shorter showers: Approximately 1.2 trillion gallons of water are used each year in the United States just for showering purposes, and showering takes up about 17% of residential water usage. The amount of water consumed and the energy cost of that consumption are directly related. The less water we use the less energy we use. And the less energy we use, the less of a negative impact we have on the environment.

Because energy-efficiency offsets are an indirect way and not a direct way of reducing emissions, they alone will not be enough to reduce global carbon emissions significantly. Direct measures of emission reductions, such as reducing individual energy use and consumption, are better alternatives to energy-efficiency offsets. 

Final Thoughts

Energy-efficiency carbon offsets are a specific type of carbon offset that upgrade conventional systems into ones that use less energy to perform the same task. CO₂ avoidance occurs immediately, making energy efficiency an effective way to reduce CO₂ emissions. But they can lack efficiency due to additionality, standardization, and monitoring concerns.

Although energy-efficiency offsets can instigate meaningful change, 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. Offsets also do not reduce your own carbon emissions, which can lead to greenwashing.

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 energy-efficiency carbon offsets.
