As businesses and individuals become more conscious of the need to reduce emissions, voluntary carbon markets are expanding. The market was valued at about $2 billion and is expected to grow to $50 billion by 2030.
Voluntary carbon markets trade various types of carbon credits, including:
- Removal credits are generated by projects that remove carbon dioxide from the atmosphere, such as reforestation or direct carbon capture and storage.
- Reduction credits are generated by projects that prevent greenhouse gas emissions, such as energy-efficient building construction, reducing emissions from deforestation and degradation (REDD), cutting methane emissions from agriculture or renewable energy investments. Sometimes, avoided emissions credits are referred to as a separate type.
To participate in the voluntary carbon market, companies and individuals purchase carbon credits from project developers responsible for generating high-quality credits. Once purchased, these credits can be used to offset emissions by submitting them to a carbon credit registry or donating them to a carbon offset project.
Carbon credits in voluntary carbon markets offer several benefits, including:
- Allowing companies and individuals to offset their emissions and reduce their environmental impact.
- Supporting the development of low-carbon technologies and projects.
- Creating jobs and boosting economic growth in developing countries.
- Raising awareness of climate change and encouraging emissions reduction efforts.
However, there are challenges in voluntary carbon markets, such as:
- Market complexity and opacity can make it difficult for buyers to assess credit quality.
- There is a risk of double counting, where identical emissions reductions are claimed more than once.
- Potential adverse social or environmental impacts of some carbon offset projects.
Carbon credits can be purchased in various ways: directly from project developers, through carbon offset providers, or via carbon markets. When selecting a carbon offset provider, it is crucial to ensure they are reputable and that their credits are high quality, often verified by third-party organizations like the Verified Carbon Standard or the Gold Standard.
Once purchased, carbon credits can be used to offset emissions in several ways:
- Submitting them to a carbon credit registry retires the credits and removes them from the market.
- Donating them to a carbon offset project supports the project and reduces emissions.
- Selling them to another company or individual is viable if you have excess credits.
Voluntary carbon markets provide a mechanism for offsetting emissions and reducing environmental impact while supporting low-carbon technologies and economic growth. However, buyers must navigate challenges such as double counting and potential negative impacts by choosing reputable providers and high-quality credits.
