We do enhanced rock weathering
We spread crushed silicate rock on local farmland to permanently remove CO2. Nutrients in our rock are released during weathering, which enriches soils and increases crop yields.
How does the subscription work?
We've made CO2 removal quick, easy and impactful for individuals.
Choose Your Package
Choose the package that fits your lifestyle and environmental aspirations, then simply complete the signup to start making a meaningful impact.
Start UNDOing
For every month you’re subscribed, we spread the amount of rock required to remove the CO2 ordered in your package. The rock starts removing CO2 as soon as it is spread.
Understand Your Impact
We'll keep you informed about the positive impact of your subscription, showing how your choice makes a difference. With the flexibility to modify or cancel anytime, your subscription can align with your lifestyle.

A planet fit for the future
Join us in our mission to fight the climate crisis by permanently locking away CO2, ensuring a liveable planet for your loved ones and future generations.
ERW has the potential to lock away up to 4 billion tonnes of CO2 per year – 40% of global removal targets. Not only does this help keep the planet liveable for future generations, but it also delivers many co-benefits for local communities.
Soil Health
Silicate rock is mineral-rich. By spreading it on agricultural land, we’re increasing soil fertility, crop yield and global food security.
Green Jobs for Local Communities
Our nutrient-rich silicate rock is given to farmers for free, reducing fertiliser costs for rural farming communities. Rather than importing machines and talent, we work with local contractors.
Ocean Health
The alkaline bicarbonate ions created during the weathering process are eventually washed out to sea, where they help deacidify our oceans and are used by marine creatures to build their shells.
Permanent
Unlike tree planting, ERW ensures that carbon is locked away for 100,000+ years. Once the CO2 has been removed, it’s locked away for geological time scales.
Rapid
When you support us, the rock will be spread within weeks of subscribing. The rock begins enriching the soil and removing CO2 straight away.
Energy Efficient
UNDO uses existing infrastructure, from the trucks that haul our rock to the farm machinery that spreads it, ensuring our operations have a 95% carbon efficiency for basalt and 90% for wollastonite.
“I subscribe to UNDO because I believe durable carbon removals are crucial to solving the climate crisis and because enhanced rock weathering is durable, scalable, and comes with a host of agronomic co-benefits.
I want my son to inherit a planet with a stable climate, healthy soils, and abundant crops, and UNDO is playing a part in that.”
“I’m a co-founder of the Green Runners and our environment, climate change and sea levels are important to me. I love what UNDO are DOING and once I understood the ‘science’ behind it, it seemed like a no-brainer for me to sign up to help reduce or offset some of my carbon footprint.
My hope for the future is that more people understand (through education and simple actions) that they can make a difference. Sometimes it feels like we are on our own, but as the community builds, there will be a tipping point as lots of individuals create a substantial change.
I want my grandchildren to live in a stable ecosystem that is not threatened by wildfires, severe flooding, rising sea levels and poor air quality and this can only happen if we reduce (UNDO) carbon.”
“For me, I subscribe to UNDO as I want to do my bit in the fight against climate change. I understand that carbon removal is a more powerful way of approaching this rather than offsetting and I believe UNDO are at the cutting edge of this sector.
I think everyone should contribute an amount they can afford and help us protect the planet.”
“Having calculated my personal carbon footprint I realised that to stop, or at least reduce climate change, we are all going to have to do our bit. Yes, Governments need to act, and businesses, but ordinary individuals particularly in richer Western nations need to bear some burden. Having set in motion a plan to insulate my house, install a heat pump and buy an electric car, the next step is to try to mitigate carbon emissions that result from my lifestyle that are largely out of my control. For me that is a love of travelling, particularly flying.
I have been a subscriber to UNDO since November 2022 and have found their website easy to use and their periodic email updates informative about their operations. I would recommend them to anyone wanting to do their bit by helping to clean up some of the carbon emissions which, let’s face it, we have all made in our lives so far.”

- Choose your package and complete the signup.
- For each month you subscribe, we spread the precise amount of rock needed to capture the CO2 specified in your subscription.
- The rock starts removing CO2 as soon as it is spread and will keep removing for decades until the full amount is sequestered, giving your subscription long-lasting value.
- For order processing, each subscription is recorded with a standard delivery date of 2040. Delivery is best effort, reflecting the long-term timeframe over which carbon removal is delivered.
- We will send you an email every time you purchase CO2, delivering you insights on the impact of your subscription.
- No strings attached – you can cancel your subscription anytime.
Your subscription begins funding our rock-spreading operations immediately. We run spreading events regularly (occasionally, due to the farming year and weather, an event may move to the following month) and we ensure the amount of rock we spread matches the amount of CO2 covered by your subscription.
The weathering process begins as soon as the rock is spread, with the full amount of CO2 gradually and permanently removed over the lifetime of the silicate rock (around 20 years). We’ll keep you updated on the total CO2 removed thanks to your subscription.
For order processing, each subscription is recorded with a standard delivery date of 2040. Delivery is best effort and reflects the long-term delivery window for carbon removal.

- The product you are purchasing is the removal of carbon dioxide from the atmosphere using UNDO’s enhanced rock weathering technology.
- Currently, this product is tied to our 20-year silicate carbon product. We will spread silicate rock on farmland, which starts removing CO2 as soon as it is spread and continues gradually removing CO2 over the next 20 years.
- The full amount of carbon removal associated with your purchase is expected to be delivered within 20 years, on a best-effort basis. For order processing, each subscription renewal is recorded with a standard delivery date of 2040.
- If you’re subscribed with us, we repeat this process every time your subscription successfully renews. Once removed, the carbon is locked away permanently.
- We’ll update you with your total impact on an ongoing basis.
- If you have purchased a subscription, it will automatically renew (either monthly or annually) on the same day that you signed up for it.
- No strings attached – you can cancel your subscription anytime.
