The Great Pacific Garbage Patch is a significant source of airborne microplastics and nanoplastics, but there are many other places where tiny plastic particles can be whipped up into the skies, including from landfills, roadside litter and car tires.
A team of scientists from China and the US have studied the makeup and behavior of these plastics, and found they are contributing to global heating, according to a new study published in the journal Nature.
They wanted to know whether particles scattered sunlight back into space — meaning they would have a cooling influence on the planet — or whether they absorbed sunlight, which would have a warming impact.
Previous research has suggested microplastics' contribution to global warming was negligible, but analyses have often assumed particles were clear, the report scientists said. What they found was a rainbow of colors.

Urban development is entering a transformation defined by measurable sustainability metrics rather than aspirational targets. Cities are adopting climate‑sensitive planning and sustainable building design that minimise energy use through form, materials and orientation. This shift aligns with environmental sustainability in construction and growing regulation around the carbon footprint of construction. Green infrastructure, vegetation and renewable building materials are being treated as core components of modern planning, establishing a foundation for eco‑friendly construction that directly contributes to net zero carbon goals.
Developers are implementing Whole Life Carbon Assessment frameworks to evaluate emissions across every project stage, from material sourcing to end‑of‑life reuse in construction. This marks a decisive move toward Whole Life Carbon accountability and Life Cycle Cost transparency. Attention to embodied carbon in materials has intensified as research converts into practice, prompting low carbon design strategies and renewable material substitution across supply chains. Lifecycle assessment and life cycle thinking in construction are no longer academic exercises but commercial tools for carbon footprint reduction and improved building lifecycle performance.
Digital innovation in procurement is enabling Circular Economy in construction models that support resource efficiency, circular construction strategies and low embodied carbon materials. Firms integrating BREEAM and forthcoming BREEAM v7 standards demonstrate how measurable sustainable building practices create long‑term value while decarbonising the built environment. Policy frameworks targeting net zero whole life carbon and carbon neutral construction now influence investment decisions across both private and public sectors.
The convergence of regulation, consumer demand and corporate responsibility signals that sustainable construction has become an operational standard. The sector’s competitive advantage increasingly depends on measurable sustainability credentials, from eco‑design for buildings to verified environmental product declarations (EPDs). As the industry redefines its purpose around durability, efficiency and circular economy principles, sustainable urban development emerges as the benchmark for global growth.
