Kew Gardens, one of the world’s most celebrated botanical institutions, has introduced the Carbon Garden, a new permanent attraction designed to deepen public understanding of carbon’s crucial role in sustaining life on Earth. Originating as a modest private garden in 1759, Kew has evolved into a sprawling 300-acre UNESCO World Heritage Site renowned for its botanical research and conservation. The Carbon Garden, which opened in late July 2025, forms part of Kew’s ambitious, decade-long sustainability strategy launched in 2021, aiming to operate as a “Climate Positive” institution by 2030.

The garden functions as a living laboratory highlighting the interplay between plants, fungi, and the carbon cycle, emphasizing their combined capacity to mitigate climate change. Visitors can explore a variety of themed areas where 35 new trees and around 6,500 plants demonstrate not only carbon capture through photosynthesis but also broader ecosystem services such as water conservation, flood control, and soil erosion prevention. Informational panels strategically placed throughout the garden provide insights into the carbon cycle, enriching the educational experience. The site is designed to encourage visitors to consider practical, everyday actions to support planetary health, fostering climate advocacy through immersive learning.

At the heart of the Carbon Garden stands a striking pavilion commissioned from Mizzi Studio, an interdisciplinary practice based in London and Malta. The pavilion’s organic form, inspired by the symbiotic relationships between plants and fungi, features a curvilinear base that broadens before contracting and expanding at the canopy, evoking fungal fruiting bodies. Jonathan Mizzi, studio director, expressed hopes that the pavilion would symbolise a harmonious future grounded in renewable natural materials and scientific wisdom. A key element of its design is its use of low-carbon stone foundations and a natural fibre composite for the canopy, which not only minimises environmental impact but also functions to capture rainwater. This feature irrigates the surrounding rain garden, composed of native grasslands, wildflower meadows, and hedgerows, chosen specifically for their carbon sequestration potential and biodiversity benefits.

This development ties into broader efforts at Kew, which include a net-zero renovation plan for the site’s historic glasshouses, further signalling the gardens’ commitment to climate-positive operations. Funded in part by the Biffa Award, the Carbon Garden aligns with Kew’s longstanding mission to combine scientific research with public engagement, aiming to inspire visitors and school groups alike through interactive educational programmes held under the pavilion canopy.

By integrating innovative garden design with climate science, Kew Gardens’ Carbon Garden not only serves as a beautiful public space but also as a pilot project exploring practical strategies for climate resilience in the UK’s changing environment. This initiative underscores the critical transition from raising awareness to galvanising collective action for environmental sustainability, a message increasingly vital as the global climate crisis intensifies.
