As the urgency to combat climate change grows, businesses are exploring tools to mitigate their environmental impact. Two prominent mechanisms—carbon credits and carbon offsets—have emerged as critical instruments in reducing greenhouse gas emissions. While both serve the ultimate goal of addressing climate change, they operate differently and cater to varied needs.
This blog unpacks the differences between carbon credits and carbon offsets, provides a clear comparison through a detailed table, and highlights case studies of real-world initiatives in India that exemplify their application.
Carbon Credits
- Carbon credits are permits that allow businesses to emit a specified amount of greenhouse gases. These are typically part of compliance markets, where governments or regulatory bodies set emission caps.
- Businesses can buy or sell these credits within the market to meet their regulatory requirements.
Example: A manufacturing company exceeding its emission limits can purchase additional credits from another company that has reduced its emissions below its allocation.
Carbon Offsets
- Carbon offsets, on the other hand, are generated by projects that actively remove or reduce greenhouse gases from the atmosphere, such as reforestation or renewable energy installations.
- These are traded in voluntary markets and are often used by companies looking to mitigate their emissions beyond compliance requirements.
Example: A tech company invests in a solar energy project to offset the emissions generated by its operations.
Key Differences Between Carbon Credits and Carbon Offsets
| Aspect | Carbon Credit | Carbon Offset |
|---|---|---|
| Definition | Permits that allow the holder to emit a specific amount of greenhouse gases, typically used within regulated compliance markets. | Reductions or removals of greenhouse gas emissions achieved through specific projects, often used voluntarily to compensate for emissions elsewhere. |
| Market Type | Primarily operate in compliance (regulated) markets where entities must adhere to emission caps set by governing bodies. | Predominantly function in voluntary markets, allowing organizations and individuals to offset their emissions by investing in environmental projects. |
| Purpose | Enable entities to meet legally mandated emission reduction targets by purchasing allowances to emit a certain amount of greenhouse gases. | Allow entities to compensate for their emissions by supporting projects that reduce or remove greenhouse gases from the atmosphere. |
| Creation | Issued by regulatory authorities as part of cap-and-trade systems; the total number of credits is limited to enforce emission reduction goals. | Generated through verified projects such as reforestation, renewable energy installations, or methane capture initiatives, each representing a quantifiable reduction in emissions. |
| Transaction Nature | Often involves trading between companies within regulated frameworks to ensure industry-wide compliance with emission limits. | Involves funding or investing in projects that actively remove or reduce emissions, often beyond what is required by law, to voluntarily mitigate one’s carbon footprint. |
| Price Determination | Prices are influenced by regulatory frameworks and can be higher due to strict compliance requirements. | Prices vary based on project type, location, and verification standards; generally, they can be lower than compliance market credits. |
| Example | A manufacturing company purchases carbon credits to comply with government-imposed emission caps. | A corporation invests in a reforestation project to offset the emissions from its operations, thereby achieving carbon neutrality. |
Examples of Carbon Credits:
1. EKI Energy Services Ltd
- Overview: EKI Energy has been instrumental in facilitating carbon credit payments to dairy farmers in India. Under the manure management program of the National Dairy Development Board (NDDB), farmers received payments for biogas plants, marking a significant milestone in India’s carbon credit landscape.
- Impact: More than 1,000 dairy farmers across seven states benefited financially, enhancing their livelihoods while contributing to sustainable agricultural practices.
Bagepalli Biogas Project
- Overview: This community-driven initiative in Karnataka promotes biogas as a cooking fuel, engaging local households to improve living conditions and reduce health risks associated with traditional cooking methods.
- Impact: The project serves 5,500 households and has been recognized for its sustainable development approach, generating carbon credits through reduced methane emissions from waste management.
3. Wind Power Projects in Andhra Pradesh and Madhya Pradesh
- Overview: Several wind power projects in these states not only contribute to renewable energy generation but also create social benefits for local communities.
- Impact: For instance, the 100 MW project in Andhra Pradesh provided clean drinking water infrastructure and improved health facilities, while the Madhya Pradesh project supported education by supplying school equipment and constructing toilets.
4. Tata Power’s Renewable Energy Initiatives
- Overview: Tata Power has engaged in various renewable energy projects that generate carbon credits through solar and wind energy production.
- Impact: Their commitment aligns with India’s broader climate goals, aiming for significant reductions in greenhouse gas emissions while promoting sustainable development.
Examples of Carbon Offsets:
1. Floating Solar Project in Tamil Nadu
- Overview: EKI Energy Services registered India’s first floating solar project under the Voluntary Carbon Market (VCM), which generates clean energy while mitigating CO2 emissions.
- Impact: This 24.7 MW project is expected to reduce approximately 38,376 tonnes of CO2 emissions annually, showcasing innovation in renewable energy solutions.
2. Infosys Community Offset Program
- Overview: Infosys has implemented a community offset program aimed at reducing firewood consumption significantly through sustainable practices.
- Impact: The initiative is projected to lower annual firewood consumption by 1.2 million tonnes over its lifespan, contributing to carbon neutrality goals.
3. Renewable Energy Carbon Offsetting Projects
- Overview: Various projects across India focus on transitioning from fossil fuels to renewable energy sources like solar and wind.
- Impact: These projects not only contribute to lowering greenhouse gas emissions but also provide economic benefits through job creation and community development.
Harnessing Carbon Credits and Offsets for Change
Carbon credits and offsets are two sides of the same coin, offering businesses pathways to mitigate their environmental impact. Carbon credits provide a direct mechanism to comply with emission regulations, while offsets enable organizations to go beyond compliance by funding meaningful environmental projects.
India’s progress in both areas is evident through innovative initiatives like the Bagepalli Biogas Project and the floating solar farm in Tamil Nadu. These projects demonstrate how businesses can leverage carbon markets to align with global sustainability goals while driving local benefits.
Whether through compliance markets or voluntary contributions, businesses have a unique opportunity to contribute to a greener, more sustainable future.
