Single climate project vs. climate project portfolio: How to choose

Companies looking to take responsibility for their ongoing emissions face a choice: support a single climate project or build a diversified carbon credit portfolio. Both approaches serve the same purpose, but the difference lies in the strategy behind it.
 

Key takeaways

• A single climate project works best when there’s a clear thematic or geographic link to your value chain, which is compelling storytelling.
• A carbon credit portfolio spreads risk across different technologies, regions, and project types, similar to an ETF.
• The two approaches aren’t mutually exclusive: companies can start with one project and evolve toward a combination over time.
• The SBTi recommends a balanced portfolio approach for addressing ongoing emissions.
• ClimatePartner’s Global Impact portfolio combines 12 projects across ten technologies and five continents.

When to choose a single climate project

Supporting a single climate project makes sense when it has a direct connection to a company's own business activities.

For instance, a food manufacturer sourcing raw materials from West Africa can support an afforestation project in the same region, contributing to emissions reductions while also strengthening supply chain resilience. Or a logistics company operating across Asia can support renewable energy projects in that region, creating a clear link between its business footprint and climate action.

Single climate projects are a strong fit when:

• there is a thematic or geographic connection to the company's own value chain
• a company wants to support a specific technology or region
• a compelling, communicable story is the priority, for example, for communications with customers or employees
• a company wants to develop its own project.

When to choose a carbon credit portfolio

The voluntary carbon market is complex. Quality standards, assessment methodologies, and regulatory requirements are constantly evolving. A single climate project carries concentration risk: natural disasters, methodological updates, or shifting frameworks can affect a project's performance.

A diversified carbon credit portfolio spreads the risk, much like an ETF in financial markets. It brings together different technologies, regions, and project types, creating a broader and more stable foundation for a company's climate action.

A climate project portfolio is particularly well suited when:

• risk diversification and stability are a priority
• a company has no strong preference for a particular technology or region
• broad impact across multiple technologies and continents is part of the communication strategy
• a company is working toward alignment with the SBTi Corporate Net-Zero Standard; the SBTi recommends taking responsibility for ongoing emissions through a balanced portfolio: near-term through high-impact projects with strong social co-benefits, and long-term through carbon removal projects.
   

How to combine a single climate project with a portfolio

A single climate project and a climate project portfolio are not mutually exclusive.

It’s possible to start with a portfolio to enter the market quickly with broad coverage. Over time, companies expand their portfolio by adding projects that are well suited to their strategy, supply chain, or corporate culture.

Others take the opposite path: years of supporting individual projects, followed by a move toward portfolio diversification. Both routes are valid. What matters is that the commitment is credible, transparent, and part of a broader climate strategy that keeps emissions reduction at its core.
 

ClimatePartner's climate project portfolio "Global Impact"

For companies looking to start with a diversified approach or expand their existing climate action, ClimatePartner has developed the climate project portfolio "Global Impact".

The Global impact portfolio brings together 12 carefully selected climate projects across ten technologies and five continents, from clean drinking water in Uganda to forest protection in Paraguay and regenerative agriculture across Europe. With 65% carbon reduction, 20% carbon avoidance, and 15% carbon removal projects, it offers a diversified contribution to global climate action.

All projects in the climate project portfolio "Global Impact" undergo ClimatePartner's multi-stage project integrity screening. Portfolio projects that have been externally assessed by rating agencies such as BeZero Carbon, Sylvera, and MSCI have received a rating of BB or higher. The portfolio supports all 17 UN Sustainable Development Goals and can be booked from as little as 1 kg of CO₂.
