Image Descriptions (1 of 2):
1: View of Earth from space cutting across diagonally so that Earth is taking up the bottom right corner. A thin red stripe stretches above the atmosphere and fades at one end. White text on the slide reads: As the world warms, what happens to the extra heat and CO2?
2: White text over an image of Earth from space. A smaller panel on the right shows a bright red swath taken from a sea surface temperature data visualization. Text reads: As more greenhouse gases are added to Earth’s atmosphere, our planet gets warmer. Most of this heat is absorbed by the ocean.
3: A haze of bright red covers most of the image. The red fades into orange and yellow towards the top. White text reads: So far, the ocean has absorbed around 90% of the added heat from decades of global warming.
4: Satellite image of Earth. A tan strip of land lines the left side. A blue-green ocean swirls on the right. White text on screen reads: As the ocean warms, it alters the global climate – from global temperature to weather patterns to sea level.

Ocean governance reforms now carry direct consequences for sustainable construction and environmental sustainability in construction. The UN High Seas Treaty and proposed protections for the Antarctic Peninsula introduce stricter environmental impact assessments for offshore and coastal developments, signalling an era of detailed whole life carbon assessment in marine-related infrastructure. Developers of subsea cables, interconnectors, and COâ‚‚ pipelines will contend with extended consenting processes and biodiversity restrictions that influence material selection, eco-friendly construction practices, and low carbon design decisions across multiple jurisdictions. The evolution of marine spatial planning aligns with circular economy in construction principles, recognising supply-chain carbon exposure as both a design and compliance issue.
Trade policy disruption poses further challenges to sustainable building design. Prospective tariffs on low-carbon materials—such as green building materials, steel, engineered timber, and heat-pump components—threaten project timelines and budgets. Anticipated responses include regional procurement strategies, adoption of sustainable material specification, and more rigorous evaluation of embodied carbon in materials and life cycle cost performance. Demands for verifiable environmental product declarations (EPDs) and building lifecycle performance metrics are expected to rise as clients seek transparency for carbon neutral construction targets.
Climate volatility is reshaping low-impact construction strategies, particularly in flood-prone and mountainous regions. Designers must adopt adaptive lifecycle assessment frameworks that prioritise redundancy, attenuation, and slope stability. These approaches support net zero whole life carbon goals and reduce the carbon footprint of construction, reinforcing resilience and resource efficiency in construction.
The policy debate on decarbonisation is shifting toward measurable outcomes. Governments are preparing performance-linked procurement and finance mechanisms that embed whole life carbon benchmarks into material supply chains. The accelerating move toward net zero carbon buildings, green construction, and BREEAM V7 standards signals the transition from intent to implementation. Markets for low embodied carbon materials and circular construction strategies are scaling at pace, defining a new baseline for sustainable building practices and comprehensive whole life carbon accountability across the global built environment.
