Offsetting Project Marketplace

Offsetting works best as part of a broader reduction strategy, not a substitute for one. Our carbon offset marketplace gives you access to verified projects from around the world and closer to home, so the credits you purchase reflect genuine climate impact and stand up to stakeholder scrutiny.
HOW IT WORKS

A curated marketplace of verified carbon offset projects

Our marketplace brings together projects across a wide range of types and geographies, giving you the flexibility to build an offsetting portfolio that fits your strategy and values.

Range of Projects

Choose projects that align with your business and reporting requirements

Not all carbon credits are equal, and not all projects suit every business. Our marketplace is structured to help you filter and select with purpose:

  • Filter by project type, geography, standard and co-benefit category
  • See full project documentation, including methodology, verification status and credit vintage
  • Understand how each project contributes to relevant UN Sustainable Development Goals
  • Match purchases to your residual emissions after reduction actions have been applied

Offsetting decisions are also supported by your carbon expert, who can advise on project selection, portfolio mix and how to communicate your approach transparently in sustainability reports and disclosures.

"I have found Seedling to be a relatively easy and hassle-free method of carbon tracking. Their web app combines sleek design with AI features, making carbon reporting easy. My favourite feature so far is the AI that matches categories to the expenditure entered. This saves lots of time and is really accurate. The team (Henry) has also been really helpful, providing individualised support where needed."

"Seedling helped us understand our carbon footprint in a clearer and more structured way. With their guidance, we were able to identify areas we could improve, especially around imported ingredients and daily operations. Their guidance on next steps was practical and realistic, especially in areas like energy use and waste management, which are important parts of our daily operations."

"We spoke to a few emission tracking partners before we spoke with Seedling, and Seedling's offer seemed too good to be true but it wasn't! Super straight forward platform, able to get face to face advice when we needed it, not expensive. Would definitely recommend."

FAQs

Your questions answered

What are carbon offset projects and how do they work?

Carbon offset projects reduce, avoid or remove greenhouse gas emissions that would otherwise occur. When a business purchases carbon credits from a verified project, each credit represents one tonne of CO2 equivalent that has been reduced or sequestered. Credits are retired on your behalf, meaning they cannot be sold or used again, and the reduction is recorded against your residual emissions.

What is the difference between nature-based and energy-based carbon offsets?

Nature-based offsets sequester carbon through ecological processes, such as tree planting, peatland restoration or forest protection. Energy-based offsets avoid emissions by replacing fossil fuels or improving efficiency, for example through renewable energy deployment or clean cookstove distribution. Both are valid under most reporting frameworks, and many businesses choose a mix to balance permanence, co-benefits and cost.

Are UK carbon offset projects better than international ones?

Neither is inherently superior, but they serve different purposes. UK projects tend to be more expensive per credit but deliver visible domestic environmental and community benefits, which can be important for businesses with UK-focused stakeholders or nature recovery commitments. International projects often offer greater scale and biodiversity co-benefits. The right balance depends on your strategy, budget and reporting context.

How do I know carbon offset credits are legitimate?

Look for credits verified against internationally recognised standards such as the Verified Carbon Standard (Verra), Gold Standard or the UK Woodland Carbon Code. These frameworks require independent auditing, transparent methodologies and public registries where credits can be tracked and retired. All projects in our marketplace meet verified standard requirements, and full documentation is available for each one.
