Article 6 of the Paris Agreement — explained
Article 6 is the part of the Paris Agreement that lets countries trade carbon reductions. It is also the most contested 14 paragraphs in international climate law.
The fundamentals
Article 6 is the part of the Paris Agreement that lets countries trade carbon reductions. It is also the most contested 14 paragraphs in international climate law. The policy category sits at the intersection of climate science, corporate accounting, and traveller behaviour — three audiences that rarely share a vocabulary, which is why so much of the public conversation about carbon ends up talking past itself.
To understand what's at stake, start with the unit. A carbon credit, an emission, a reduction, a removal, an offset — these all reduce to a single tonne of carbon-dioxide-equivalent (tCO₂e). Methane, nitrous oxide, hydrofluorocarbons, and other greenhouse gases convert to that same unit using IPCC global-warming-potential factors. Once everything is denominated in tCO₂e, the comparisons become possible.
The regulatory frame
Climate regulation in 2026 operates on three layers. International (UNFCCC, Paris Agreement Article 6), regional (EU ETS, CBAM, CSRD), and national (domestic carbon taxes, sectoral targets, disclosure requirements). The travel industry sits inside all three — CORSIA at the international level for aviation, EU CBAM for any goods imported into Europe, and a patchwork of national disclosure rules including the UK's SECR, France's Loi Énergie-Climat, and California's SB-253.
Hotels themselves are mostly unregulated for direct emissions, but they sit downstream of regulated electricity grids and upstream of regulated corporate buyers (every Fortune 500 hospitality account is now reporting Scope 3 hotel-stay emissions). The regulatory squeeze is therefore indirect but real — properties that cannot measure and disclose their carbon are losing contracts.
The IMPT angle
When you book a hotel through IMPT, one verified tonne of CO₂ retires automatically against your booking. The credit comes from a Verra- or Gold Standard-listed project, default-weighted toward removal-track methodologies (biochar and mangrove restoration). The retirement is recorded on-chain with your booking ID, queryable for life. No add-on fee, no upsell at checkout, no opt-in box.
It is not a perfect climate solution — no single travel booking is. It is, however, one of the cleanest carbon accounting units in the consumer travel category, and it survives the same questions you would ask of a corporate climate disclosure: is it real, is it additional, is it permanent, is it verifiable? The answer to all four is yes, and the registry record is one click away from your confirmation email.
What to do next
Two practical actions. First — if you've booked a hotel through any platform in the last year, check whether the offset they advertised actually retired to a registry serial in your name. Most don't. Second — when you next book travel, choose a platform where the offset is included by default rather than upsold at checkout, where the credit is removal-weighted rather than avoidance-only, and where the retirement record is queryable by your booking ID. That short checklist filters out roughly 90% of the marketing claims in the category.
Book a hotel — one tonne of CO₂ retired automatically.
Every IMPT hotel booking retires one Verra- or Gold Standard-listed carbon credit on your behalf. No add-on fee, no upsell, no catalogue. Just verified, on-chain retirement.
