What Makes a Carbon Credit Worth Buying?
A carbon credit is a tradable certificate that represents the verified reduction or removal of one metric tonne of carbon dioxide equivalent (CO2e) from the atmosphere. The principle is straightforward: a project that demonstrably reduces emissions earns credits. An organisation that purchases and retires those credits can count the reduction toward its own climate targets.
How a carbon credit is created
Not every emission reduction automatically becomes a credit. A project must first demonstrate that its impact is real, additional (meaning it would not have happened without the intervention), and measurable. The reductions are then independently verified by a third party before credits are issued in an official registry. This chain of measurement, reporting, and verification, commonly referred to as MRV, is what separates a high-integrity credit from an empty claim.
Katla Carbon's model is built around exactly this logic. The emission reductions generated by girls' education are quantified using peer-reviewed science, open-source datasets including the Shared Socioeconomic Pathways (SSP) framework, and IPCC emission factors, modelled over a 50-year period to capture how the climate benefits of education accumulate across generations. Every Katla project will undergo tri-annual monitoring throughout the implementation period and mandatory third-party verification upon completion.
Two types of markets
Carbon credits exist in two broad markets. Compliance markets are legally binding: companies or governments must acquire credits if they exceed regulated emission limits. Voluntary markets are chosen: organisations go beyond legal requirements because they have set their own net-zero or sustainability targets. According to the World Bank's State and Trends of Carbon Pricing Report 2025, carbon pricing instruments now cover around 28 percent of global greenhouse gas emissions and mobilised over $100 billion for public budgets in 2024.
Katla's credits will operate in the voluntary market, giving corporate partners a way to extend their climate commitment beyond their own value chain and into communities that are most vulnerable to the effects of climate change, while contributing directly to measurable progress on the UN Sustainable Development Goals.
Why integrity matters more than ever
The carbon market has faced justified scrutiny. A significant share of older offset credits lacked verifiable emission savings, eroding trust in the instrument as a whole. In response, global standard-setters have raised the bar. The Integrity Council for the Voluntary Carbon Market (ICVCM) has developed its Core Carbon Principles, ten science-based minimum standards that any credible credit must meet.
Integrity Label from the ICVCM
Katla's verification process is designed to reflect this heightened standard. When projects reach completion, all Katla Carbon credits will be audited by ISO 14065:2013-accredited verification bodies against ISO 14064-2:2019 requirements, with enhanced criteria covering additionality, permanence, and safeguards against leakage. Credits will be registered with blockchain-backed traceability, linking each credit directly to a specific student cohort and audit report. Verification and credit issuance follow upon completion of each project — once the girls supported have finished their education.
Girls' education as a project type also carries what Katla describes as inherent climate integrity: additionality is automatic because every additional year of schooling creates new, measurable reductions that would not otherwise exist; permanence is built in through the intergenerational impact of educated women compounding across decades; and leakage is systemically prevented because the intervention transforms entire communities rather than simply shifting emissions elsewhere.
What this means for partners
Carbon credits should never replace genuine emissions reductions within an organisation's own operations. When used responsibly, to address residual and historic emissions alongside real decarbonisation efforts, a high-integrity credit offers something that internal reductions alone cannot: the ability to collaborate on climate action that reaches far beyond the value chain. A Katla credit will connect a corporate climate commitment directly to a girl in Zambia who stayed in school, with a fully documented, verified, and traceable chain of evidence to back it up.
