Found on seabeds from Alaska to Australia, seagrass meadows are one of the most widespread coastal habitats on Earth. While they cover just one thousandth of the ocean floor, these marine plants play an important role in aquatic ecosystems — from providing nursery grounds for marine species, to storing up to 18% of the ocean's carbon.
But this vital underwater habitat is in decline — with a loss of about 7% a year globally — due to factors like coastal development, climate change, overfishing and pollution.
ReefGen, a company that's working to repopulate lost seagrass habitats around the globe, wants to help. Five years ago, ReefGen was formed by Google X cofounder Tom Chi, who witnessed the decline of coral reefs close to his home in Hawaii and turned to engineering and robotics for solutions.
ReefGen first engineered a robot named Cora that plants coral plugs onto reefs to help regenerate them. Cora provided the foundation for Grasshopper – the startup's seagrass planting iteration.

England’s first Land Use Framework sets a benchmark for sustainable construction by embedding integrated planning across housing, energy and nature. It defines a new standard for sustainable building design that prioritises whole life carbon assessment and reduction of embodied carbon in materials. Projects that combine housing density with renewable energy generation and biodiversity enhancement will align most effectively with environmental sustainability in construction.
Policy efforts to allow single wind turbines up to 30 metres on business or public estates without full planning consent will stimulate low carbon design and accelerate the shift to energy-efficient buildings. Rising electricity costs reinforce the commercial value of life cycle cost analysis and lifecycle assessment in both retrofit and new build strategies. The focus is moving from headline technologies to fabric upgrades, controls, demand management and end-of-life reuse in construction—core aspects of circular economy in construction models that aim to cut the carbon footprint of construction portfolios.
Nature-based solutions now underpin green infrastructure policy. Research into moss and other renewable building materials shows the potential of green construction interventions to manage stormwater and pollution through low-impact construction techniques. These examples affirm the circular construction strategies and eco-design for buildings that the industry must mainstream to achieve net zero carbon buildings.
Developers integrating whole life carbon measurement, resource efficiency in construction and sustainable material specification will not only strengthen environmental performance but also reduce project risk within the evolving regulatory landscape. The transition towards a circular economy, carbon neutral construction and sustainable urban development is positioning the sector closer to net zero whole life carbon delivery, redefining sustainable building practices across the UK and beyond.
Whole Life Carbon is a platform for the entire construction industry—both in the UK and internationally. We track the latest publications, debates, and events related to whole life guidance and sustainability. If you have any enquiries or opinions to share, please do
