Reliable, high integrity carbon credits

We go above and beyond required certification to ensure that our project deliver maximum co-benefits.

Projects registered with Puro.earth

Our projects are registered with Puro.earth - the leading registry for high-tech engineered carbon removals.

Puro CORCs have established themselves as a secure and reliable carbon removal choice for leading businesses looking to support GHG removals, and buyers include Microsoft, Google, Shopify and SwissRe. Over 1.7 million credits have been issued and growing fast.

As of June 2026 the price of 1 CORC (1 ton of CO2 equivalent removed) is €140 and steadily rising.

Credit Integrity

We ensure that each of our projects deliver high value, certifiable benefits.

Feedstock selection

We seek out feedstocks with little alternative value, and in some cases causing environmental damage, and we site our plants close to source to minimize transportation.

Energy utilization

It is common for pyrolysis projects to vent excess heat generated, but we only choose sites where the energy has value in displacing higher emitting alternative sources.

dMRV

Our proprietary technology comes with robust and immutable performance measurement ensuring that accurate data is the foundation of all our carbon credits.

Biochar

We are proactive in the biochar market, actively engaging customers for who biochar can deliver the best outcomes, resulting in more sustainable practices in agriculture or materials.

Co-benefits

We choose our sites where the employment and social impact can deliver positive outcomes for local communities and increase economic and environmental resilience.
