Eighteen years ago this week, I was running the press office for Interbuild 2008 at Birmingham's NEC.
Seven months pregnant and merrily taking a plaster cast of the foot of legendary environmental activist, David Bellamy (as you do!) to mark the opening of the exhibition’s ‘Eco Village’ trail.
Just your average day in PR!
Known for his booming, gravelly voice, hyper-energetic presentation style, and distinctive beard, David Bellamy inspired an entire generation to care about ecology, biodiversity and environmental issues long before it became a mainstream political movement. Looking after David that day in the press office green room, as he gently recounted many bygone tales, I was also fascinated to learn that this larger than life man had adopted several children from across the globe.
From PR Stunts to Net-Zero Mandates
As the photo memory resurfaced this week, it prompted me to reflect and look back at how the industry I have worked in, for almost 30 years has changed and adapted since this image was captured - in particular, how sustainability in the built environment has shifted up a gear over the past two decades too.
Back then, we threw around buzzwords and engineered PR stunts to shine spotlights on new products that merely looked and felt a bit greener. Sustainability was mainly focused on improving basic operational energy performances and efficiencies with products such as heat pumps and pushing government backed grants to encourage home owners to adopt better forms of loft insulation. There was the odd bit of global warming climate talk too.
Engineering Responsibility
Gone are the days when "green building" simply meant adding recycling bins to a commercial scheme.
Driven by strict climate targets and engineering breakthroughs, the built environment and building materials industries are now required to balance structural integrity with genuine environmental responsibility. Clean technology is no longer an afterthought; it is now actively baked into modern architecture and design. And we have moved beyond standard solar rooftop panels with energy-generating windows, and sleek solar facades, whilst massive leaps have been witnessed in off-grid solar lighting and battery technology to support critical infrastructure programmes.
In parallel, heavy manufacturing is tackling its biggest hurdles. The production of concrete and cement, historically responsible for roughly 8% of global carbon emissions, has undergone critical, industry-wide optimisation to drastically reduce its reliance on carbon-intensive manufacturing. Concurrently, ultra-low energy building concepts have graduated from individual, niche eco-homes into the baseline blueprint for large-scale social housing and commercial developments.
Data and Closed-Loop Futures
The way we design and construct has been completely overhauled by software, data automation, and circular design principles. Traditional, linear supply chains are rapidly shifting toward closed-loop systems centered on retention, restoration, and reuse. Buildings are increasingly engineered to be taken apart at the end of their lifecycles, ensuring materials can be repurposed rather than sent to landfills. Advanced projects now use digital logs to track exactly what materials are inside a building, where they came from, and how they can be safely recycled decades down the line.
The Next Generation of Strides
Sustainability hits us a bit heavier than it did in 2008 and is no longer an optional path. Over the past 20 years, sustainability has evolved into a mainstream business, regulatory, and financial priority:
The 2000s (The PR Era): Sustainability was largely driven by Corporate Social Responsibility (CSR). It was treated as a philanthropy or marketing exercise, completely decoupled from core financial planning.
The 2010s (The Framework Era): The launch of the UN SDGs (2015) and the Paris Climate Agreement shifted the conversation toward measurable targets. Investors began demanding Environmental, Social, and Governance (ESG) metrics to assess long-term risk.
The 2020s (The Regulation Era): Today, sustainability is a matter of strict legal and financial compliance. Frameworks like Europe's Corporate Sustainability Reporting Directive (CSRD) mean sustainability data must be as transparent, auditable, and rigorous as financial accounting.
My son will soon turn eighteen and step out into the big wide world. Perhaps our global green efforts are slowly growing up too.
