A breath of fresh air 😮💨
For the past 17 years, @nasa’s Aura satellite has watched our air get cleaner.
Nitrogen dioxide (NO2) is released into the atmosphere from burning fossil fuels, such as coal power plants or gasoline and diesel vehicles. This air pollutant has been linked to health problems including asthma. NASA’s Aura satellite has been measuring NO2 for nearly two decades.
This animation shows the yearly average NO2 from 2005 to 2022. You can see the air get cleaner. The cleaner air is primarily due to environmental rules that have helped reduce air pollution from power plants and cars.

Video Description: A data visualization of average nitrogen dioxide levels over the United States as measured from space from 2005 to 2022. At the start of the animation, dark purple spots are seen over major cities throughout the country indicating high levels of air pollution. Rural areas are shown in light blue indicating low nitrogen dioxide levels. The dark purple spots fade into orange and then yellow as you move away from large city centers, however most of the Northeast is some shade of yellow-purple. As time moves forward the dark purple spots slowly shrink and fade leaving the majority of the map light blue with only small concentrations of dark purple over New York and Los Angeles.
Sustainable construction is moving from ambition to enforceable systems change, with electrified buildings, resilience and whole life carbon now shaping development strategy. Calls for a UK 2035 electrification target covering heat pumps, solar, batteries and clean technologies put pressure on developers to align sustainable building design with low-carbon power, flexible demand and on-site generation. Fabric-first design remains vital, but net zero carbon buildings will increasingly depend on operational performance, smart controls and credible whole life carbon assessment.
Global energy markets are accelerating the shift. Forecasts of a 4,800GW rise in renewable capacity by 2035, supported by China’s clean-tech export strength, are changing the economics of building services. Heat pumps, battery storage and intelligent controls are becoming core infrastructure for energy-efficient buildings, not optional upgrades. Future-ready assets will need low carbon design capable of using variable clean electricity while protecting occupiers from volatile fossil fuel costs and reducing the carbon footprint of construction over time.
Regulation is tightening around measurable performance. The Future Homes Standard is forcing design teams to reassess roofs, floors, comfort, ventilation and commissioning, while building-controls specialists are urging ministers to turn efficiency policy into practical support for businesses. BREEAM, BREEAM v7 and lifecycle assessment frameworks are becoming more important for demonstrating environmental sustainability in construction, linking embodied carbon, operational energy, life cycle cost and building lifecycle performance in a single evidence base.
The next phase of green construction will demand stronger action on embodied carbon in materials, low carbon construction materials and sustainable material specification. Developers, architects and contractors face growing pressure to use environmental product declarations (EPDs), low embodied carbon materials, renewable building materials and green building products to prove carbon footprint reduction. Circular economy in construction is also moving up the agenda, with circular construction strategies, resource efficiency in construction and end-of-life reuse in construction becoming central to net zero whole life carbon delivery.
Climate adaptation is now a capital planning issue. New flood and coastal-defence schemes in England and Wales show that green infrastructure, sustainable urban development and low-impact construction must protect assets from climate risks already locked in. Sustainable architecture and eco-design for buildings can no longer treat resilience separately from decarbonising the built environment. The industry must deliver eco-friendly construction, carbon neutral construction and sustainable building practices that reduce the environmental impact of construction while preparing communities for more extreme weather.
