Indonesia’s Drowning Land
Parts of the country's coastline are disappearing as sea levels rise
Indonesia is the world’s fourth most populous country and its largest archipelagic nation, comprising over 17,000 islands. With the majority of these islands sitting only one meter above sea level, coastal areas in many parts of the country are being threatened by rising sea levels caused by climate change. Deforestation, landscape reclamation, and the illegal extraction of groundwater by the industry on the coasts make these areas even more vulnerable to rising sea levels.
Sea level rise is often talked about as a potential future impact of climate change. But on the Indonesian island of Java, it is already threatening millions of people. Rising sea levels are already having a significant impact on coastal areas of Java, such as Pekalongan in Central Java and Karawang in West Java.

Progress towards sustainable construction is uneven yet gathering momentum. The UK government has launched Great British Energy, aimed at publicly owned clean energy generation. While not construction-specific, its success by 2030 could transform the carbon footprint of construction by providing a cleaner grid. A stable low-carbon energy supply underpins sustainable building design and supports net zero whole life carbon ambitions across the built environment.
In the United States, financial close on Massachusetts’ largest battery energy storage project promises better grid stability for low carbon design. Enhanced storage capacity creates more reliable access to renewable electricity, improving whole life carbon assessment outcomes for housing and commercial development. This shift towards energy-efficient buildings demonstrates how infrastructure investment feeds directly into sustainable architecture and sustainable building practices worldwide.
Macquarie’s US$350 million investment in solar and storage via Nexamp reinforces the integration of renewable building materials and decentralised clean energy into urban development. Sourcing electricity from localised systems allows eco-design for buildings to achieve measurable carbon footprint reduction. For large-scale projects, life cycle cost thinking in construction is increasingly impossible without accounting for such infrastructure, linked directly to lifecycle assessment and future BREEAM v7 updates.
Hydrostor has attracted major funding for compressed air energy storage, providing long-duration capacity essential for decarbonising the built environment. This kind of resilience directly supports sustainable construction by ensuring clean energy availability through both build and operational phases. It also complements whole life carbon strategies, reducing reliance on fossil fuels while supporting environmental sustainability in construction and measurable building lifecycle performance.
On resilience, Flood Risk America has developed an automatic flood gate that eliminates the need for manual intervention. This technology represents circular construction strategies in disaster adaptation, ensuring eco-friendly construction can withstand climate extremes. As urban areas pursue sustainable urban development, such measures demonstrate how resource efficiency in construction can align with climate resilience.
Warnings from the Environmental Services Association highlight the hidden risks in electrification. Battery disposal fires, costing billions annually, underline the environmental impact of construction supply chains beyond embodied carbon in materials and end-of-life reuse in construction. Safe disposal and sustainable material specification are critical to maintaining environmental product declarations (EPDs) credibility, reinforcing the broader shift toward circular economy in construction.
