Carbon Credits for Business | Corporate Offsetting
Carbon credits for business use help organisations take measurable climate action. GreenTonne gives you access to verified credits from the world's leading registries, along with bulk purchasing, API integration, and retirement certificates for ESG reporting.
Why Carbon Credits for Business Matter
Businesses face growing pressure from regulators, investors, and consumers to demonstrate measurable climate action. As a result, GreenTonne provides a direct path to voluntary carbon offsetting through verified credits from Verra VCS and Gold Standard registries. Whether you support voluntary climate action or strengthen internal sustainability reporting, our platform delivers the transparency your organisation needs.
How to Buy Carbon Credits for Business
Calculate Your Business Emissions
First, estimate your corporate carbon footprint using the GreenTonne emissions calculator. You can also integrate directly with our API to automate calculations. As a result, you can track Scope 1, 2, and 3 emissions categories in one place.
Choose Verified Carbon Credit Projects
Next, select from hundreds of verified projects worldwide. Then filter by credit quality, geographic location, and project type. You can also choose co-benefits such as biodiversity, community development, and clean water access.
Retire Credits and Report Your Impact
Finally, retire purchased credits directly on the registry and receive detailed retirement certificates. Consequently, you can use these certificates in your annual sustainability reports, CDP disclosures, and ESG documentation with full serial number traceability.
Carbon Credits for Business: API Integration
Integrate carbon offsetting directly into your business workflows with the GreenTonne REST API. For example, you can automate credit purchasing, retirement, and certificate generation programmatically. In addition, you receive webhook notifications for transaction events including purchase confirmations, retirement completions, and certificate issuance. This makes it ideal for e-commerce platforms and travel booking systems. Logistics providers can also offer offsets at transparent prices.
Carbon Credits for Business: ESG Retirement Certificates
Every credit retired on GreenTonne generates a verifiable retirement certificate that records the transaction fields buyers commonly retain for review and reporting. Specifically, each certificate includes the registry name, project details, vintage year, quantity retired, unique serial numbers, retirement date, and a public verification URL. As a result, you can share certificates directly in annual sustainability reports, CDP climate change questionnaires, GRI disclosures, and investor presentations. Moreover, every offset is independently verifiable on the underlying registry, which gives your reporting full traceability.
