Why a Portfolio Approach to Carbon Credits is Best

As more companies deepen their commitment to sustainability and explore the Voluntary Carbon Market (VCM), the question of how to best purchase carbon credits becomes increasingly critical. While it may be tempting to purchase and retire credits from individual projects based on ease of purchasing, location, stories, or price, building a carbon credit portfolio from multiple projects offers several key benefits for buyers looking to drive meaningful climate action.

Trust the Experts

Experts across science and industry agree that buyers should consider a portfolio approach when purchasing carbon credits. The Oxford Principles for Net Zero Aligned Carbon Offsetting, widely regarded as “best practices” in the field and endorsed by the World Economic Forum, recommend diversification across project types, while transitioning to removals with long-term storage over time.

Oxford Principles for Net Zero Carbon Offsetting

Experts like World Business Council for Sustainable Development (WBCSD) with Bain & Company have suggested that companies use portfolios to mitigate risk while pursuing their climate leadership goals and follow the “Oxford Principles” to do so. 

The Four Key Benefits of a Portfolio Approach

Much like financial portfolios, carbon credit portfolios allow buyers to balance risk and impact by diversifying their investments. Here’s a closer look at the benefits:

  1. Mitigate Risk: Like any market, there is risk involved in the VCM. Reduce risk by investing across several projects so that you’re not dependent on one specific project’s outcome or even one project type.
  2. Diversify Impact: Support projects across various project types and geographies to influence multiple beyond carbon factors like community, biodiversity, and ecosystem benefits.
  3. Balance Impact & Affordability: Stick to your budget by creating the right mix of differently priced projects for a price per tonne that works for you.
  4. Build a Sustainable Future: Support a range of project technologies to reduce the need for avoided emissions projects while helping novel technologies get to scale, building the groundwork for a future where we can be investing only in long-term carbon removal projects.

Mitigate Risk

Despite rigorous due diligence and monitoring safeguards, it is impossible to fully eliminate the risks that exist in the carbon market, as with any market. Projects can face challenges such as environmental disruptions, delayed construction timelines, or regulatory changes. For example, a reforestation project could be impacted by a wildfire or an Enhanced Rock Weathering (ERW) facility could face a years-long delay awaiting permit approval. 

A portfolio approach reduces your overall risk and minimizes overreliance on one specific project or technology, to ensure that the overall investment remains resilient. 

Diversify Impact

All projects provide different benefits that go beyond their climate impacts based on project type, geography, and specific project activities. For example, the Katingan Mentaya peatland conservation project in Indonesia provides biodiversity benefits by preserving a vast area of peat swamp forest, protecting numerous endangered species like proboscis monkeys and Sunda pangolins. Meanwhile, the Heartland Methane Abatement project in Oklahoma plugs orphaned oil wells which supports community and environmental health, as unplugged wells leach toxic chemicals that pollute the air and contaminate groundwater. 

By investing in a portfolio of projects, you’re able to maximize and diversify your overall impact.

Balance Impact & Affordability

With a wide variety of project types, there is a huge range in the price per tonne of each project. For example, a high-quality natural gas leak repair project can cost <$10/tonne, while a Direct Air Capture (DAC) project can cost up to $600-$1,000/tonne. It would be impossible for most organizations to achieve their climate goals of supporting the necessary range of projects while sticking to their budgets, by investing in just one project or project type.

Portfolios enable organizations to strike a balance between high-cost, high-impact removals and more affordable reduction projects. This ensures alignment with best practices while staying within budget.

Build a Sustainable Future

According to the IPCC, we need to achieve net zero carbon emissions by 2050 to meet the Paris-aligned goals and avoid the worst impacts of climate change. In order to do so, we need to be avoiding and reducing our emissions now, and removing any residual emissions. There are currently technological and financial constraints that limit the amount of carbon we can remove, but supporting the most promising technologies in the space is critical to catalyzing development of their technologies in a way that helps them scale. While we’re not there yet, we hope that over time we will have collectively reduced emissions to a point where we are able to invest only in removal projects and reach net zero.

Portfolios play a vital role in this transition by supporting:

  1. Avoidance projects to address immediate carbon emissions
  2. Removal projects to accelerate technological advancement and cost reduction, paving the way for a future where removals dominate the market

The only way to secure a sustainable future for ourselves is to support a range of projects through a high-quality portfolio.
