From a distance, the Ivanpah solar plant looks like a shimmering lake in the Mojave Desert. Up close, it's a vast alien-like installation of hundreds of thousand of mirrors pointed at three towers, each taller than the Statue of Liberty. When this plant opened near the California-Nevada border in early 2014, it was pitched as the future of solar power. Just over a decade later, it's closing.
For some, Ivanpah now stands as a huge, shiny monument to wasted tax dollars and environmental damage — campaign groups long criticized the plant for its impact on desert wildlife. For others, failures like this are a natural part of the race to find the winning solutions for the clean energy transition.
So, where did it go wrong?
First, the technology proved finnicky and never quite worked as well as intended, said Jenny Chase, a solar analyst at BloombergNEF. But perhaps the biggest problem for Ivanpah is that photovoltaic solar — the technology used in solar panels — became really, really cheap.
Ivanpahs's location in the sweeping, sun-drenched Mojave Desert may have seemed ideal for generating solar power, but it is also a habitat for threatened desert tortoises. While the plant's developers agreed to a series of measures to protect and relocate the animals, many environmentalists believed the plant should not have been approved. The other big issue was bird deaths. Reports of "streamers" — birds incinerated midair by the beams of intense heat from the mirrors — solidified opposition.

The global construction industry is closely monitoring outcomes from COP30 in Belém as debates over adaptation finance and emissions targets intensify. The summit’s negotiation gridlock between developed and developing nations exposes an ongoing failure to bridge the funding gap required for climate-resilient and sustainable construction across vulnerable regions such as Bangladesh. The absence of robust financial frameworks is delaying progress in carbon neutral construction and the implementation of Whole Life Carbon Assessment methodologies critical to achieving net zero Whole Life Carbon performance in buildings facing extreme weather risks.
Brazil’s role as both host nation and custodian of the Amazon shapes new tensions between deforestation, low carbon design policy ambitions, and land-use reforms that threaten global carbon footprint reduction progress. Any weakening of environmental safeguards could undermine decarbonising the built environment strategies and erode the circular economy in construction principles that underpin resource efficiency in construction initiatives.
In the UK, the Environmental Audit Committee has reaffirmed that nature-positive planning regulations are not impeding housing supply, strengthening the argument for sustainable building design and eco-design for buildings within urban policy frameworks. The Committee’s position supports the expansion of green infrastructure and sustainable urban development through data-led lifecycle assessment and Life Cycle Cost analysis tools linked to environmental product declarations (EPDs).
Industry leaders continue to push for measurable progress beyond declarations. Adoption of BREEAM v7 and low embodied carbon materials specifications signals growing attention to the embodied carbon challenge and the environmental impact of construction. Better integration of circular construction strategies and end-of-life reuse in construction practices would enhance building lifecycle performance while advancing the Circular Economy transition.
As the built environment sector moves toward net zero carbon buildings, practitioners recognise that tangible decarbonisation relies on aligning public policy, private finance, and innovation in sustainable building practices. The momentum from COP30 underscores that environmental sustainability in construction is not merely policy rhetoric but a technical and economic imperative demanding global coordination.
