Take Action Today

The most recent IPCC report is clear: we need carbon removal to achieve global net zero by 2050 and to stay within the Paris Agreement’s 1.5°C warming target. Alongside drastic decarbonisation, impactful and durable carbon removal solutions are essential to address businesses’ residual emissions.

We Align With The Core Carbon Principles

UNDO’s carbon removal solution of enhanced rock weathering (ERW) embodies our unwavering commitment to the globally accepted ICVCM Core Carbon Principles. As we navigate the challenges of climate change, we offer businesses a credible path to environmental responsibility.

Permanent Carbon Removal

By choosing our solution, businesses can be confident that carbon is locked away securely for 100,000+ years. This sets us apart from other carbon offsetting methods, ensuring lasting sequestration and a meaningful, measurable impact on global climate efforts.

Methodology and Alignment with UN Goals

We follow the ICROA-certified methodology, in addition to aligning with global aims including the UN Sustainable Development Goals such as Climate Action and Life on Land.

Agricultural Partnerships and Co-Benefits

Our collaboration with agricultural partners goes beyond just carbon removal. Academic studies show that our solution boosts crop yields and bolsters soil health, supporting local farming communities.

Every year, natural rock weathering removes 1 billion tonnes of CO2. By spreading crushed silicate rock on agricultural land, UNDO dramatically accelerates this geological process. This combination of nature and innovation has the potential to address 40% of global CO2 removal targets.

Soil Health

Adding mineral-rich silicate rock to agricultural land improves soil fertility, leading to higher crop yields. At scale, this process has the potential to improve global food security and aligns seamlessly with established EU Soil Standards.

Community Empowerment

By supplying farmers with silicate rock and collaborating with local contractors, we’re not only boosting rural economies but also establishing a carbon removal solution rooted in the Oxford Offsetting Principles.

Ocean Health

The bicarbonate ions released during the rock weathering process counteract ocean acidification, directly benefiting marine ecosystems and strengthening the health of our oceans.

Circular Efficiency

Utilising an aggregate by-product, like basalt, resonates with our commitment to circularity. With an estimated 600 million tonnes of basalt rock available globally, we’re turning Earth’s mineral resources into an effective carbon removal solution.

Nature-inspired Innovation

By accelerating a natural geological process, our approach locks away carbon at an unprecedented rate, seamlessly merging time-tested methods with advanced technology.

Aligned for Impact

Our carbon removal solution, aligned with the ICROA-endorsed Puro Standard methodology, demonstrate our unwavering commitment to authentic and impactful climate solutions.

Safe and Effective

We ensure that the silicate rock used is thoroughly screened and vetted, ensuring it’s always safe and effective for spreading on agricultural land.

Prioritising Affordability

As one of the fastest-scaling carbon removal technologies, we’re on a mission to drive down the cost per tonne to make climate solutions more accessible.

Case Study

Our Partnership with Microsoft

UNDO is Microsoft’s first supplier for carbon removal via ERW, supporting Microsoft’s commitment to becoming carbon negative by 2030 and removing all of its historic CO2 emissions by 2050. In 2023, we spread 25,000 tonnes of mineral-rich basalt rock on agricultural land in the UK, which will permanently remove approximately 5,000 tonnes of CO2 over the next 20 years.

Carbon Offsetting For Businesses

Start, continue or accelerate your business’ decarbonisation journey with an approach that effortlessly integrates into your carbon strategy. With UNDO’s trusted carbon removals, your business can align its ambitions with real-world climate solutions.

Conduct a comprehensive assessment of the entirety of your business’ emissions, including direct and indirect emissions. UNDO collaborates with a range of partners who can guide you through this crucial step, helping you establish a clear and actionable carbon benchmark.

It’s not just about decreasing your carbon footprint but striving to eliminate it. Identify and implement strategies to minimise emissions, targeting business operations suitable for decarbonisation. The Science Based Targets initiative (SBTi) emphasises the need for businesses to rapidly reduce emissions and set near-term targets that halve emissions by 2030.

After first rapidly decarbonising, it’s estimated that approximately 10% of residual emissions need to be offset with high-permanence carbon removals. Aligned with the Core Carbon Principles and in harmony with the guidelines set by the SBTi, UNDO’s technology provides a robust solution to removing your business’ hard-to-abate emissions –  bringing you closer to net zero.
