What Does a Cat Have to Do With Carbon?
The average domestic cat has a carbon footprint of approximately 310 kg CO₂e per year — from food production, litter manufacturing, veterinary visits, and the supply chain behind every squeaky toy. Globally, with an estimated 600 million pet cats, that adds up to roughly 186 million tonnes of CO₂e annually — comparable to the total emissions of a mid-sized country.
It is a striking number, and it raises an obvious question: could you offset your cat’s carbon footprint? The voluntary carbon market says yes. For somewhere between $3 and $50, depending on the project and the credit quality, you can purchase carbon credits that theoretically neutralize Whiskers’ annual emissions.
But should you? And more importantly — does it actually work?
The Promise of Voluntary Carbon Markets
The voluntary carbon market (VCM) was built on an elegant idea: allow companies and individuals to fund emission reductions or carbon removals elsewhere when they cannot (or have not yet) reduced their own emissions to zero. In theory, a well-functioning VCM channels capital to projects that would not otherwise exist — renewable energy in developing countries, forest conservation, direct air capture, methane destruction.
At its peak in 2021, the VCM moved over $2 billion in transactions. Corporate net-zero pledges drove demand. Offset brokers multiplied. The narrative was simple: buy credits, claim neutrality.
The Integrity Crisis
Then the cracks appeared. A series of investigative reports in 2022 and 2023 revealed systemic problems:
- Additionality failures: Many forest conservation credits were protecting forests that were never at risk of being cut down. The “avoided deforestation” was avoiding something that was not going to happen.
- Over-crediting: Projects issued far more credits than the actual emission reductions they delivered. One major registry was found to have over-credited by as much as 90% on certain project types.
- Permanence questions: Forest-based credits assumed carbon storage for 100 years. Wildfires, illegal logging, and policy changes undermined those assumptions within a decade.
- Double counting: The same emission reduction was sometimes claimed by the project developer, the credit buyer, and the host country’s national inventory.
The result was a credibility collapse. Credit prices crashed. Major corporates pulled back from offset claims. The word “carbon neutral” became legally risky in the EU and several other jurisdictions.
What Comes Next: The Quality Pivot
The VCM is not dead — but it is being rebuilt. The Integrity Council for the Voluntary Carbon Market (ICVCM) has introduced Core Carbon Principles (CCPs) that set a quality floor for credits. The Voluntary Carbon Markets Integrity Initiative (VCMI) is defining credible corporate claims. New methodologies prioritize removal over avoidance, permanence over estimates, and measurement over modeling.
The market is splitting into two tiers:
- High-integrity credits (engineered removals, verified biochar, direct air capture): $30–150+/tonne, limited supply, growing demand from serious corporate buyers.
- Legacy avoidance credits (REDD+, renewable energy certificates in markets that already have clean grids): $1–5/tonne, oversupplied, declining credibility.
Back to the Cat
So can you offset your cat’s 310 kg of annual emissions? Technically, yes. But the quality of that offset matters enormously:
- A $1.50 avoidance credit from a questionable forestry project? Probably not delivering real climate benefit.
- A $45 engineered carbon removal credit from a verified biochar or DAC project? Likely real, permanent, and additional.
The difference between $1.50 and $45 is the difference between greenwashing and genuine climate action. And that gap is exactly what the market is now trying to close.
What This Means for Business
For companies navigating carbon strategy, the lesson from the VCM’s growing pains is clear: measurement before mitigation, mitigation before offsets. The regulatory world — CBAM, CSRD, SEC climate rules — is moving toward mandatory, verified emissions data. Offsets are a complement to reduction, not a substitute.
CarbonSig helps companies get the foundation right: accurate product carbon footprints, verified against international standards, ready for regulatory disclosure and commercial use. Once you know your actual emissions, you can make informed decisions about reduction strategies — and, if appropriate, which carbon credits are worth buying.
