Scientists have scoured the depths of the ocean and outer space for microbes to help slow global warming. They're now looking at a new and unlikely place — inside your home.
A group called the Two Frontiers Project (2FP) is asking people in the United States to look for "weird microbial growth" at home, in a quest to find the next microorganism that could suck planet-heating carbon dioxide from the air or help break down environmental pollutants.
Extremophile microbes thrive in harsh environments and develop unique properties, which can be harnessed by the biotech industry and used in climate solutions, said Braden Tierney, the executive director of 2FP.
Though microbes live on every home surface, the group is especially interested in those that live in more extreme environments, including places with high temperatures such as dishwashers, air conditioners, microwaves, solar panels, hot water heaters and shower heads.

Wildfires destroying homes in the Midlands and Shropshire crews moving between fire and flood show why sustainable construction must now treat climate resilience as a core design requirement. Sustainable building design, low carbon design and eco-design for buildings need to account for overheating, fire risk, drainage capacity, defensible space and durable fabric performance.
Whole life carbon, embodied carbon and life cycle cost are becoming inseparable from safety, insurability and asset value, making whole life carbon assessment and lifecycle assessment essential tools for developers, councils and investors.
Karachi’s mangrove loss reinforces the construction value of green infrastructure and nature-based flood protection. Tidal creeks, mangrove belts and resilient coastal landscapes can reduce erosion, store carbon and protect communities, supporting environmental sustainability in construction without relying solely on hard engineering. For sustainable urban development, green construction and eco-friendly construction must prioritise site planning, biodiversity and building lifecycle performance alongside energy-efficient buildings and net zero carbon buildings.
Plans for a wind-turbine recycling facility in the Scottish Highlands point to a more mature circular economy in construction. Renewable infrastructure must address end-of-life reuse in construction, resource efficiency in construction and the embodied carbon in materials, especially composite blades and complex low carbon construction materials. The shift supports circular construction strategies, low embodied carbon materials and net zero whole life carbon targets, aligning with BREEAM, BREEAM v7 and wider expectations for environmental product declarations (EPDs). The strongest signal for decarbonising the built environment is clear: sustainable building practices must measure the carbon footprint of construction across design, use, maintenance and decommissioning.
