Biochar in Catalunya. The easy way to take part.

If you live, work or run a business in Catalunya, you have probably been told that biochar is complicated. It is — at the registry and methodology level. At the buyer level, in 2026, it has become genuinely simple, provided you use a route that retires credits at the moment of action.

For a reader in Catalunya, the biochar route in 2026 mirrors the global structure — a UN-eligible registry issues credits, buyers retire them, the retirement record is permanent. Local regulatory frames (national ETS, CSRD transposition, disclosure rules) shape how the receipt is used downstream, but the underlying instrument is global.

The product surfaces below — hotels, marketplace, widget, B2B Corporate ESG, country / city representation, OSS affiliate, Goodness rewards — all route to the same registry-grade retirement record. The difference is the friction. A hotel booking takes 60 seconds. A widget install takes 5 minutes. A B2B integration takes a 15-minute call. Pick the rung that matches your situation in Catalunya and the rest is automatic.

How biochar actually works

Biochar credit issuance begins with feedstock certification: the project developer must prove the biomass would otherwise have decomposed (releasing methane or CO₂) or been burned in open piles. Verra's VM0044 and Puro.earth's methodology both require lifecycle analysis to confirm net negativity — accounting for diesel in feedstock transport, electricity for pyrolysis, and any methane slip from storage. Only the carbon permanently sequestered in biochar, minus all emissions in the supply chain, becomes the credit numerator. Production data are logged continuously: kiln temperature, residence time, feedstock moisture, and biochar yield. Post-pyrolysis, samples undergo elemental analysis (measuring fixed carbon and hydrogen-to-carbon ratios) to calculate carbon content, typically 60–85 per cent by mass. The biochar is then applied to farmland, pasture, or forestry soils under monitored conditions. Third-party verifiers — accredited by the registry — audit production records, lab reports, and soil-application GPS logs before credits are issued into the registry's serialised ledger. Retirement happens when a buyer purchases credits and instructs the registry to cancel them against a specific entity or event, preventing double-counting. Puro.earth, Verra, Gold Standard, ACR, and CAR all maintain public retirement logs showing serial numbers, project ID, vintage year, and buyer name (unless anonymised). Corporate buyers using the GHG Protocol's scope-3 guidance must retire credits in the same reporting year they claim neutralisation; forward contracts for future biochar deliveries do not count until the underlying tonne is produced, verified, and retired. Key registries include Puro.earth (Finland-based, engineered-carbon-removal focus), Verra (global, VM0044 biochar methodology), Gold Standard (co-benefits emphasis), American Carbon Registry (ACR, US focus), Climate Action Reserve (CAR, North America), and the European Biochar Certificate (EBC, soil-amendment quality plus carbon). Some projects list on multiple registries; buyers must check the registry of retirement to avoid double-issuance risk.

Who participates

Individual consumers engage biochar through climate-platform subscriptions (Wren, Klima, Patch portfolios) or direct purchases from producers like Pacific Biochar, Carbon Gold, or Oregon Biochar Solutions. A typical consumer subscription retires 0.5–1.0 tonnes per month for £8–15, though biochar often sits alongside forestry or direct-air-capture credits in blended portfolios. Transparency varies: best-practice platforms display project registry links and serial-number proof of retirement. Small and medium enterprises — restaurants, logistics firms, e-commerce shops — use biochar to address Scope 3 emissions from shipping or supply chains, often bundling removal with renewable-energy certificates. SBTi-aligned SMEs may reserve biochar for residual emissions (post-abatement) rather than baseline offsetting. Examples include UK craft breweries retiring biochar credits for barley-transport emissions and Scandinavian SaaS firms neutralising employee-commute footprints. Forward offtake agreements (committing to buy future tonnes at fixed prices) help biochar producers secure project finance. Large corporates and financial institutions dominate volume. Microsoft's $1 billion climate-innovation fund has multi-year biochar contracts with producers in the US and Australia; Stripe Climate allocates a portion of its £11+ million annual budget to biochar; and Swiss Re purchased 30,000 biochar credits in 2023 for internal neutralisation. Under CSRD, firms like Unilever, Nestlé, and HSBC must report financed and supply-chain emissions, driving demand for durable removals. Governments and multilaterals participate through pilot programmes: the World Bank's BioCarbon Fund explored biochar in Kenya, and the EU Innovation Fund co-finances pyrolysis plants in France and Germany, though public procurement of credits remains limited compared to corporate voluntary buyers.

How to take part via IMPT

IMPT offers one route among many for individuals and organisations looking to retire biochar and other high-quality carbon credits. Through partnerships with verified registries, the platform enables users to purchase fractional or whole-tonne credits — including biochar removal — and retire them on an immutable blockchain ledger for transparent proof. For example, travellers booking select hotels through IMPT's network automatically retire one tonne of certified CO₂ (which may include biochar in the project portfolio) per eligible stay, with serial numbers recorded on-chain. Corporate buyers can integrate IMPT's API or white-label marketplace to let employees or customers retire credits at checkout, embedding climate action into everyday transactions. Community and affiliate-site owners access an open-source widget to offer climate contributions without upfront cost, earning Goodness rewards (IMPT's non-tradable loyalty token) rather than cash commission — keeping incentives aligned with impact, not revenue share. B2B arrangements are tailored per market and regulatory environment (CSRD in the EU, ISSB in the UK, voluntary in other regions), with IMPT handling registry liaison, vintage tracking, and retirement documentation. This provides a simplified on-ramp, though buyers retain full responsibility for due diligence on project quality, additionality, and alignment with their own net-zero strategy.
