When HubSpot selected us as one of their favourite ‘green websites’, they were thinking about visual design, not sustainability. But it sparked a moment of reflection for us: what really makes a website sustainable?
Sustainability is now firmly embedded in mainstream business thinking. Organisations regularly evaluate their environmental impact across operations, suppliers, and infrastructure.
Digital presence, however, is still rarely examined with the same scrutiny. We don’t often think about the environmental impact of websites, yet every page load relies on servers, data centres, networks, and devices – all of which consume energy. Digital experiences have an environmental footprint, just like ‘real-world’ experiences.
But there is growing awareness of the energy demands of internet services, which has been reflected in recent industry coverage. When leading software development company HubSpot explored the topic of green websites, they looked at how brands communicate their environmental values through design and digital strategy. Within that discussion, our website was highlighted for its distinctive use of green within the site’s visual identity.
But while colour is a powerful brand signal, it also prompts a deeper question: what actually makes a website green?
The colour green has long been associated with sustainability, responsibility, and environmental awareness. It is one of the most commonly used visual cues for brands that want to communicate those values.
Yet visual identity alone does not determine environmental impact; a website’s footprint is shaped by decisions that sit well beneath the surface, including:
A site can look environmentally conscious while operating in a highly inefficient way.
Each visit to a website triggers activity across multiple layers of infrastructure. Data centres process requests, networks transmit information, and devices render content. Supporting systems such as cooling operate continuously. And at scale, even minor inefficiencies accumulate quickly: larger page sizes, unoptimised assets, and excessive scripts all increase resource consumption. Efficiency is not only a performance concern; it is an environmental one.
One of the most influential factors in a website’s operational impact is its hosting provider, as data centres differ significantly in how they source and manage energy. Some rely heavily on fossil fuels, while others prioritise renewable energy and invest in efficiency improvements. Selecting infrastructure with stronger sustainability credentials can materially reduce a site’s footprint, without altering its design or functionality.
As part of our own sustainability evaluation, we ran tigermarketing.co.uk through the Green Web Foundation’s verification system. The Green Web Foundation does not rely on marketing claims. It matches IP data against independently maintained datasets of verified hosting providers. This offers a practical way to assess infrastructure decisions that are otherwise invisible.
The check identified Google Cloud as the underlying provider – and confirmed our site is hosted green.
Being included within HubSpot’s exploration of green websites was an interesting moment for us; the reference centred on visual design, yet it highlights a broader consideration for any brand.
Colour communicates intent, while your choice of infrastructure defines your impact. When both point in the same direction, brand expression and operational decisions reinforce each other rather than existing purely at a surface level.
There is often a perception that sustainability efforts are restrictive, and even when it comes to web practices, people tend to assume that working towards a more sustainable online presence will be limiting. But in reality, they typically align with performance optimisation and user experience improvements. Efficiency-focused decisions commonly support:
A greener website is better for users, better for performance, and better for resource usage.
If you want to understand your business’s own hosting environment, start by using the Green Web Check tool. A quick test can reveal infrastructure choices that rarely feature in day-to-day discussions.
As digital infrastructure expands and becomes ever more resource-intensive, the idea of a ‘green website’ is moving far beyond visual branding and into operational reality. Efficiency, performance, and infrastructure choices are becoming increasingly important.
For brands that take both their online presence and sustainability seriously, this need not be limiting or restrictive. It’s a natural extension of responsible design and infrastructure decisions.
