CNN Climate 1 year ago

The Trump administration quietly released key climate change data last week that has historically been accompanied by expert analysis from government scientists at the National Oceanic and Atmospheric Administration, CNN has learned. The lack of context minimized the government's own findings that atmospheric levels of carbon dioxide — the most abundant planet-warming gas in the air — jumped up by a record amount in 2024. Instead of issuing a public-facing web story with an explanation of the annual measurement, as the agency has at this time of year for about a decade, NOAA public affairs officials scuttled those plans and instead released the new data on X and Facebook on April 14, sources at the agency told CNN. The social media posts link to NOAA's CO2 data-tracking web page. The episode, along with recent budget and staffing cuts, illustrates the Trump administration's resistance to publicly distributing climate change-related data. The posts on X and Facebook, for example, did not call attention to the record-high rate of year-over-year increase in CO2 concentrations. NOAA has also suspended monthly climate press calls during which scientists would discuss global temperatures and the reasons for particular trends. There is no indication NOAA limited its scientists' ability to speak with the press about the annual CO2 data. A NOAA spokesperson did not reply to a request for comment.

Momentum in sustainable construction is now driven by tangible progress in materials and methods rather than declarations. The focus on reducing embodied carbon in materials and undertaking robust whole life carbon assessment is reshaping how developers, architects and engineers define sustainable building design. Initiatives such as the Reducing Plastics in Construction Summit reinforce the value of renewable building materials, eco-design for buildings and circular economy in construction frameworks to eliminate petroleum-based polymers and improve resource efficiency in construction.

Biobased composites, recyclable resins and modular approaches are being evaluated through lifecycle assessment tools that can accurately measure the carbon footprint of construction and inform sustainable material specification throughout each project stage. Digitisation is rapidly becoming integral to low carbon design and energy-efficient buildings. Advanced platforms now enable unified modelling of cost, performance and carbon, aligning lifecycle cost optimisation with environmental sustainability in construction.

TM2 Bygg’s software-led method illustrates how low carbon building processes built on data-driven insights help achieve net zero carbon buildings and deliver improved building lifecycle performance. At the policy level, regulators are reinforcing requirements for measurable reductions in embodied carbon and clear evidence of net zero whole life carbon outcomes. These shifts point toward an industry-wide transformation grounded in whole life carbon transparency and the adoption of BREEAM v7 and other sustainable building practices to standardise reporting.

The result is a market that values circular construction strategies, end-of-life reuse in construction and environmental product declarations (EPDs) as verification of a project’s environmental impact of construction. New renewable energy infrastructure, including next‑generation geothermal systems, could redefine the carbon footprint reduction potential of green building materials and low carbon construction materials. As baseload renewables expand, achieving carbon neutral construction and sustainable urban development becomes increasingly viable. The sector is moving beyond pilot projects toward a mature phase of green construction, integrating life cycle thinking in construction and decarbonising the built environment as core business practice.
