On 16 June, more than 200 leaders from government, business, science and civil society gathered in Baarn for the National Summit on Nature-Based Carbon Removal. Organised by Climate Cleanup together with Oncra and the provinces of Gelderland, Utrecht, Noord-Holland, Zuid-Holland, Noord-Brabant and Drenthe, the summit focused on one central question: how do we accelerate the…
Some weeks ago (April 30 – May 3), 140 people gathered on Bart van Beuzekom‘s land in the tiny Portuguese village of Cidadelhe. Not just to dance and listen, but above all to dig. Over a few mornings, they built 69 Smilands together: small landscape interventions that hold rainwater and gather dew on ground that…
When Hajna talks about her work, two things come through quickly: she loves data, and she believes in frontrunners. As one of the people behind Oncra‘s (carbon credits certification platform, initiated by Climate Cleanup) Land Stored Carbon certification, she helps farmers, including food foresters and land stewards, quantify what their land is doing for the…
By Tamara Szilágyi-Hajdú, May 2026MA Gender Studies | BSocSC Politics and International Relations Tamara wrote this piece as part of her thesis research, conducted during her time at Climate Cleanup. Introduction The concept of climate justice points out that climate change is a symptom of a system of oppression, a system of extraction and exploitation for…
Dutch farmers are increasingly turning to the Paulownia tree — also known as Kiri wood — for its fast growth, high timber yield, and the extra income it generates through verified CO₂ certificates. Unlike traditional crops, Paulownia can be harvested after just 8 to 10 years, and the tree regrows straight from the stump, offering…
Robert Pol is 62 years old, married, and the father of thirty-year-old twins. He works as a senior innovator at Van Aalsburg, a family business now in its third generation. “A wonderful title,” he calls it himself. His work? Developing new products based on willow. “When I was six years old, I already wanted to…
Somewhere off the coast of Mexico, a vessel moves slowly through open water. It’s not fishing. It’s not surveying. It’s hunting seaweed. Why? To take carbon out of the atmosphere, while buying fragile coastlines a little more time. That vessel is the latest chapter in a story that started 25 years ago, underwater. A career…
An interview with Laura Rooseboom, board member at Climate Cleanup From “boring finance” to meaningful impact “I used to work in traditional asset management,” Laura Rooseboom says with a smile. “Investing in everything and anything. But honestly? I found it quite boring.” What she was missing was purpose, and innovation. Not just new ideas, but…
What does it take to transform the way we build, grow food, and relate to the planet? In this conversation, Jelle de Bijl (Certification Manager at Construction Stored Carbon) and Gijs Tolmeijer (Business Developer for both Climate Cleanup and Oncra), both working at Climate Cleanup, sit down to talk about their work, what drives them,…
What if the problem is not that we don’t know enough, but that we’ve forgotten how to truly see? For Marie-Claire Greve, photographer and long-time ambassador for Climate Cleanup, the starting point is not urgency, but attention. Not crisis, but connection. And, more fundamentally, a renewed sense of value. “The moment people begin to feel…
Coming back from the European Carbon Farming Summit in Padua on 17-19 March, one thing is clear: carbon farming and certification are entering a new phase. The conversation is shifting: from pilots and promises to systems, standards, and scalability. Hajna Tijssen from Oncra noted down a few reflections of the summit: 1. Carbon farming as…
Bamboo Village Uganda develops several bamboo afforestation projects in Uganda. Bamboo acts as a natural carbon sink: it removes CO2 emitted from the atmosphere and stores it in the soil and the plant. The benefits of Bamboo Village Uganda’s project extend beyond environmental impact. The project actively invests in the local community and generates a…
Woody Builders creates commercial buildings that work with nature instead of against it. Using wood, technology and bio-based materials, they design structures that store CO₂, reduce emissions and offer healthier, more inspiring places to work and live. Thanks to their Oncra certification, their wooden designs are not only environmentally sustainable, but also financially sound and future-proof, giving…
Last week, our Construction Stored Carbon lead Sacha was in Brussels to attend the EU Expert Group on Carbon Removals. Under the Carbon Removals and Carbon Farming (CRCF) Regulation, the EU will enforce certification methodologies for permanent carbon removals (1), carbon farming (2) and carbon storage in (building) products (3). These methodologies are developed in…
The European Commission has opened public consultation on the draft rules for certifying carbon farming across the EU: the Carbon Removals and Carbon Farming Regulation (CRCF). This is your chance to shape how farmers and foresters get certified and paid for storing carbon. Feedback deadline: 19 February 2026 on the EU’s “Have Your Say” portal….
To maximise the amount of carbon your store in a biobased building, it is key to calculate the carbon storage of different designs quickly, easily and accurately. Having an accurate and understandable calculation method also enables everyone in the value chain, from developer to tendering municipality, to set clear goals. These two worlds, of design and goal-setting,…
Tijdens de eerste koolstofvastleggingstafels brachten we ondernemers, marktpartijen, beleidsmakers, investeerders en experts samen om te verkennen hoe we koolstofvastlegging met natuurgebaseerde oplossingen kunnen opschalen op Nederlandse bodem. De energie was hoog en de bereidheid om samen door te pakken is groot. Hieronder delen we de belangrijkste uitkomsten van de werksessies en de vervolgstappen. Uitkomsten werksessies…
