Do you believe new construction materials will successfully reduce the environmental impact of modern building projects?
Published in early October 2026, the book Future Build: How Construction Can Heal Our Planet by Will Arnold details the environmental footprint of modern building practices. The work analyzes how sector-wide shifts in materials and construction methods are required to address the industry's significant global resource consumption.
Why it matters
The book highlights a major shift in emissions profiles, where embodied carbon in building materials now rivals the operational energy usage of modern homes. This evolution requires architects and clients to rethink material procurement and structural design to move beyond mere energy efficiency.
The construction industry currently consumes 50% of all annually extracted raw materials and accounts for one-third of global waste. While homes built in 1996 derived 80% of their total emissions from energy use, modern residential structures typically split their carbon impact 50-50 between energy and materials.
The players
Will Arnold
The author and engineer who led sustainable construction initiatives including the Rwanda Institute for Conservation Agriculture project.
The details
Future Build examines how systemic changes, such as the adoption of alternative cement, hydrogen-based steelmaking, and enhanced glass recycling, can mitigate the industry's 10% share of global emissions. The author emphasizes that these technical interventions are essential to reducing the carbon debt locked into buildings during the construction phase. Drawing on lessons from the 2018 Rwanda Institute for Conservation Agriculture project, the text outlines how early-stage decision-making by project owners influences the eventual environmental outcome.
Timeline
1996: A typical home relied on energy use for 80% of its total emissions.
2018: Will Arnold managed a project at the Rwanda Institute for Conservation Agriculture.
Early October 2026: Future Build: How Construction Can Heal Our Planet was published.
The Tech Race
Future Build recontextualizes the industry's sustainability goals by moving focus away from purely operational energy savings. It serves as a pragmatic guide for navigating the technical trade-offs inherent in shifting toward low-carbon materials like alternative cements and green steel.
Project owners and developers can use the framework in Future Build to set clearer sustainability targets during the initial design phase of new construction. The methodologies provide a technical basis for comparing the carbon lifecycle of traditional versus alternative building materials.
The takeaway
The trajectory of green building is moving from simple insulation improvements to the systemic decarbonization of raw materials. Readers can track this shift by monitoring the adoption of green steel and alternative cement standards in upcoming municipal building codes.
