The levels of carbon dioxide in our atmosphere are now higher than ever in human history. The need of the hour is to reduce the amount of greenhouse gases in the atmosphere to control serious issues such as Global Warming and Climate Change.

In this article, we will discuss one such strategy - Carbon Offsets.

Carbon offset comes from the most basic idea: You give something, you get something or Quid Pro Quo.

With this idea, if you emit X amount of CO2 into the atmosphere in one location, you can offset it by investing in a carbon-reducing activity in a different location to compensate for part or all your carbon footprint.

Carbon offsetting is used to compensate for your emissions by funding an equivalent carbon dioxide saving elsewhere.

An organization takes actions like planting trees, building wind farms, solar power plants, etc., to compensate for their carbon emissions. If they compensate enough to offset their carbon footprint, they effectively become carbon neutral.

Carbon offsets fall under two broad categories:

1. Carbon Emissions Avoidance

Carbon emissions avoidance is a technique which results in future emissions being avoided or reduced. Organizations take up some common types of emissions avoidance such as renewable energy projects, forest conservation or management or carbon capture and storage. These methods are further explained below.

2. Carbon Removal

Carbon removal projects physically remove existing carbon from the atmosphere. This can be through a natural process or through technological innovations. For e.g., afforestation and reforestation are natural methods of carbon removal.

Direct air capture (DAC) is a chemical process of removing carbon from the atmosphere directly. Large fans draw air into the DAC plant. Different chemical processes such as Electro swing and Solid/Liquid DAC are used to re-release air into the atmosphere devoid of CO2.

Carbon Offsetting works in 4 major steps:

• Step 1: An individual or company can pay a broker to remove a portion of carbon from the atmosphere, often in another part of the world.
• Step 2: The customer calculates their emissions level.
• Step 3: The broker then charges a fee based on that level.
• Step 4: The broker will then invest a portion of that money in a project that reduces carbon emissions.

Organizations and individuals pursue carbon offsetting voluntarily or to comply with regulations.

Individuals can make donations or purchase an offset credit. This money promotes carbon storage or reduction, such as planting/saving trees, developing wind or solar farms, etc. You can do this to help offset your carbon emissions.

Carbon Offsets allow businesses that can't immediately reduce their emissions to balance things out by buying emissions reductions somewhere else. Businesses focus on becoming carbon-neutral or achieving net-zero emissions through carbon offsetting.

Some examples of carbon offsetting projects are the following:

• Forest Regeneration: Tree planting projects restore areas facing deforestation. An organization helps renew forest land natural or artificial means.
• Supporting Regenerative Farming: Farmers grow crops using technology and techniques to maximize resources and reduce waste. This technique focuses on soil quality and protecting biodiversity.
• Investing in Climate Projects: Climate projects that focus on researching, developing and marketing sustainable alternatives to everyday problems/products that can help reduce excessive carbon emissions.
• Building Renewable Energy: These projects replace fossil fuel use with clean, renewable energy, such as that generated from wind or solar farms.
• Waste and Landfill Management: One major problem with landfills is the significant emission of methane gases. Through waste and landfill management projects, organizations invest in capturing methane gas from such places.
• Securing Renewable and Sustainable Modes for Operations and Functioning: This project aims to improve the efficiency of existing infrastructure by upgrading building insulation, using cleaner energy, developing and implementing efficient operations, etc.
• Carbon Sequestration: These projects promote carbon capture and storage to put carbon in places where it's unlikely to be released back into the atmosphere. They take carbon out of the air and store it in soil, swamps, trees and even in rocks.

There are many organizations that monetize carbon removal/reduction techniques through 'carbon credits'. It is important for individuals and corporations who truly want to make a positive impact on the environment to verify these carbon-offsetting institutions.

This helps in accurate reporting, data tracking and transparency that will not only build credibility, but also help authorities and agencies better their climate actions and plans.

There are several quality markers to look out for when verifying successful carbon offsetting, such as:

Carbon offsetting is possible because climate change is a non-localized problem. Greenhouse gases mix throughout the atmosphere, so reducing them anywhere contributes to overall climate protection. While in theory carbon offsets seem like a golden idea, their efficiency remains in question.

Most offsets available on the market don't reliably reduce emissions. A carbon offset requires to have the feature of 'additionality'. The project must accurately measure the amount of CO2 being kept out of the atmosphere. This process requires transparency and well-documented standards and protocols to verify that the project is doing everything it claims.

Although carbon offsets have appealing benefits, it is difficult to verify their environmental benefits. Yet, they are now the backbone of environmental policies of many of the biggest polluters of the planet.

Offsets are not the only answer to climate change. It seems like an easy solution but to have actual impact, more real and hard work is required.

So, what can be done?

If you really want to make a difference,

• Start reducing the engagement in carbon-creating activities in the first place that would make more of a difference.
• Prioritize carbon removal, instead of reduction; projects which offer innovative and permanent storage solutions.
• Rather than opting for projects that invest your money towards planting more trees or saving forests, opt for clean-energy projects – anything from distributing efficient cooking stoves to capturing methane gas at landfill sites. Energy-based projects such as these are designed to make quicker and more permanent savings along with offering social benefits.

Carbon offsetting can help reduce carbon emissions and mitigate the effects of climate change, but it can't solve the problem entirely on its own.
