The ambitious Kew Carbon Garden project combines scientific research with beautiful design to inspire climate action through natural solutions.
Kew Gardens in London launched its most ambitious environmental project in years on July 25, 2025. The new Kew Carbon Garden showcases stunning plant displays and innovative design, demonstrating to visitors how nature can help mitigate the climate crisis.
This permanent garden transforms complex climate science into visual experiences that anyone can understand. Walking through the Kew Carbon Garden, visitors see exactly how plants and fungi capture carbon from the air and store it safely underground.
Living in Montreal, I know how challenging it can be to explain climate change to friends and family. The Kew Carbon Garden addresses this problem by allowing people to see the solutions with their own eyes. Instead of reading statistics about carbon dioxide, visitors experience how different plants actually remove it from the atmosphere.
The garden starts with a powerful visual display inspired by climate stripes from Reading University. These colourful plantings show how global temperatures have risen dramatically over time. Visitors see red and orange flowers, representing the hottest years, which creates an immediate understanding of climate change without the need for confusing graphs or numbers.
A striking coal seam display reveals fossilized plants, connecting today’s fossil fuel problems to ancient vegetation. This exhibit helps people understand that the oil and gas contributing to climate change actually originated from plants that lived millions of years ago. The irony becomes clear: plants created the problem unintentionally, and plants can help fix it intentionally.
The dry garden section within the Kew Carbon Garden prepares visitors for London’s future climate. Drought-tolerant plants, such as Parry’s agave and lavender, show what gardens might look like in 30 years as temperatures rise.

Thirty-five new trees have been planted throughout the garden, demonstrating nature’s ability to capture carbon. Trees remove carbon dioxide from the air during photosynthesis and store it in their wood, roots, and surrounding soil. In cities like London and Montreal, these trees also provide cooling shade, cleaner air, and flood protection during storms.
The rain garden shows how proper water management helps plants store more carbon. When soil holds the right amount of moisture, plant roots grow deeper and microorganisms thrive. These underground communities capture carbon and store it for decades or centuries.
Native grasslands, wildflower meadows, and hedgerows throughout the Kew Carbon Garden not only boost biodiversity but also store carbon. Scientists have discovered that diverse plant communities store more carbon than single-species plantings. When different plants work together, their root systems create complex underground networks that trap carbon more effectively.
A unique pavilion, designed by Mizzi Studio, sits at the garden’s centre, resembling a giant mushroom. This structure celebrates the partnership between plants and fungi, which work together to store carbon in soil. The building’s tilted roof directs rainwater into the rain garden below, showing how human design can support natural processes.
Kew Gardens employs over 500 scientists and 150 horticulturists who study how plants mitigate the effects of climate change. Their research reveals that grasslands, hedgerows, and woodlands capture much more carbon than previously thought. This discovery could change how governments and landowners manage natural spaces.
The scientists are also identifying which trees will survive future climate conditions. Using Kew’s collection of 11,000 trees, researchers test different species against heat, drought, and extreme weather. This work helps cities choose the right trees for long-term carbon storage and climate resilience.
For ordinary people, the Kew Carbon Garden provides clear actions anyone can take. Planting native species in home gardens, supporting local conservation projects, and choosing products from companies that protect forests all make a difference. The garden demonstrates that individual choices collectively contribute to meaningful climate action.
The project received funding from the Biffa Award through the Landfill Communities Fund and money raised by People’s Postcode Lottery players. This community support demonstrates how everyday people can fund large-scale environmental solutions. When lottery players buy tickets or communities support local environmental projects, that money creates real change.
Climate change can feel overwhelming when presented as abstract data, but visitors to the Kew Carbon Garden discover concrete solutions that work. Visitors leave understanding that plants and fungi are powerful allies in climate repair, armed with practical knowledge they can apply in their own communities and confident that nature offers real pathways to a healthier planet.
