Carbon credits you can trust

CNaught offers the simplest way to purchase high-integrity carbon credits, with our curated selection of science-backed portfolios. We help companies save time and avoid the complicated project selection process, enabling them to immediately reduce their carbon footprints and their risk of greenwashing–all at competitive prices.

CNaught also offers a carbon credit API for companies that want to programmatically offer carbon-neutral products and services to their customers.

Carbon credits are a critical tool for companies to mitigate the emissions in their value chain that they cannot currently reduce or avoid. But project quality is uneven, the market is opaque, and companies often are unsure what to buy, where to buy it, or how much to pay.

CNaught curates diversified portfolios made up exclusively of credits from projects that are highly rated by independent 3rd party agencies and that pass our internal diligence process. Diversification plus diligence helps you maximize impact while minimizing risk.

CNaught’s portfolio approach follows Oxford's Principles for Carbon Offsetting, supported by the World Economic Forum. CNaught’s portfolios are made up of four different categories of project types, which build on a paradigm laid out in the Oxford Principles. Consistent with Oxford, we weight our current portfolios toward the highest-impact technologies currently available at scale: the best avoided emissions projects. At the same time, we allocate a meaningful portion of our portfolios toward carbon removal projects with both short and long-term storage because it is critical that carbon removal solutions scale if we are to meet our climate goals. Over time we believe the weight of the portfolio will shift toward removal and longer-term storage as removal solutions scale and global progress on emission reductions also reduces the number of avoided emission projects.

It’s important to use a portfolio approach because similar to a financial portfolio, spreading investment across multiple project types and geographies mitigates risk, diversifies impact across factors like biodiversity and community benefits, and lets buyers balance impact with affordability rather than depending on any single project's outcome. CNaught’s portfolio approach aligns with experts in the industry like World Economic Forum and University of Oxford.

You can reduce greenwashing risk by buying only high-integrity carbon credits and being transparent about how you use them, which is the foundation of CNaught's approach. CNaught puts every project through a 7-step diligence process backed by ratings from all four leading agencies—BeZero, Calyx Global, Renoster, and Sylvera—and stands behind it with the CNaught Guarantee, so your climate claims stay credible and defensible. CNaught also gives you clear reporting and impact-sharing tools that help you communicate your progress in accurate, accessible language rather than vague or inflated claims.

CNaught runs every project through a 7-step diligence process that combines internal assessment with independent third-party ratings, and it's one of the only companies to use ratings from all four top agencies: BeZero, Calyx Global, Renoster, and Sylvera. Each project is evaluated across four quality pillars—additionality, over-crediting, durability, and double counting—and only projects meeting CNaught's integrity criteria are eligible for portfolios. In practice, this means that only about 15% of credits available in the voluntary carbon market will meet our due diligence requirements and be eligible for inclusion in our portfolios.

According to the Paris Agreement, we need to transition the global economy to net zero by 2050 to avoid the most severe consequences of climate change. While internal decarbonization efforts are crucial, it is not yet financially or technically feasible to transition to a zero carbon economy today. Carbon credits allow you to take immediate responsibility for 100% of your emissions by offering a flexible, cost-effective alternative to bridge the gap between current operations and future emissions reductions.

In addition to providing immediate climate impact, carbon credits deliver business value through brand building, stakeholder alignment, risk mitigation, and more.
