Nature-based carbon projects
Forestry, mangroves, peatland restoration, regenerative agriculture — nature-based carbon does more than fix CO₂. The trade-offs explained.
The fundamentals
Forestry, mangroves, peatland restoration, regenerative agriculture — nature-based carbon does more than fix CO₂. The trade-offs explained. The project type 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.
Where this fits in the supply mix
Across the global voluntary carbon market, project types fall into roughly four buckets — nature-based avoidance (REDD+, forest conservation), nature-based removal (afforestation, biochar, mangroves), engineered removal (DAC, enhanced rock weathering), and emission reduction (renewable energy, methane capture, fuel switching). Each has its own permanence profile, additionality argument, monitoring methodology, and price band.
The category that matters most for any given buyer depends on what they're trying to achieve. A corporate buyer with a 1.5°C-aligned SBTi target needs to show emission reductions inside its own value chain first, and then can use removal credits for the residual that cannot be eliminated. A traveller offsetting a stay is in a different position — they aren't trying to neutralise their entire footprint, they're trying to add one credible tonne of climate benefit to the transaction.
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.
