Businesses today face growing pressure to meet Environmental, Social, and Governance (ESG) targets, yet turning sustainable intentions into consistent impactful actions is no small feat. Many find themselves searching for a practical, cost-effective way to make these ambitious goals a reality.
That’s where behavioural science comes in. In this blog, we’ll explore how subtle, yet highly effective techniques like “nudging” can influence decision making to foster sustainable practices and create lasting change, empowering businesses to make a meaningful impact and secure ESG goals.
What’s a Nudge?
A “nudge” is something which influences decision making without restricting freedom of choice, in the context of sustainability, it involves structuring choices so that employees, customers and stakeholders naturally gravitate towards and instinctively choose eco-friendly options, reducing both environmental impacts and costs The concept was popularised by Thaler and Sunstein in their book, “Nudge: Improving Decisions About Health, Wealth, and Happiness”1. The power of nudging lies in its ability to shape choice architecture, where small changes in the way options are presented can lead to significant behavioural shifts.
Nudge Theory’s Potential in Sustainability
Unlike costly traditional methods like education or financial incentives/penalties, nudging acts on the cognitive processes that drive our behaviour. Nudge theory has the potential to transform our efforts towards sustainability by designing environments and systems that make sustainable options the default, driving large-scale environmental impact with minimal resistance.
Implementing nudges can save time and money. It’s the obvious choice, so why haven’t we heard about it more?
How Nudge has been Underutilised in Sustainability
Like many of us, I strive to make eco-conscious choices. I avoid single-use plastic, reduce my meat consumption, and walk whenever possible. Yet, despite my efforts, I’m guilty of “indulgences” that outright contradict my sustainability efforts—I prefer paper to Word, I don’t think I’ve ever had a shower that lasted less than 5 minutes, and I drive to work multiple times a week. While these personal actions affect my individual carbon footprint, they also tie into a larger narrative: the carbon footprint of the organisations and systems I am part of.
This reflects a broader problem. Despite our growing awareness of environmental challenges, we’ve largely failed to drive widespread, impactful changes in sustainability at scale. For example, recycling rates in England have stagnated at around 40% for the past decade, with no significant progress despite government backed efforts to promote more sustainable waste management practices¹. Yes, people and businesses often have the best of intentions, but we are not always ethical or consistent decision-makers. Research shows that there is an “intention-action gap”—the disconnect between what we say we value and how we actually behave.
This is where Nudge Theory and behavioural science could be transformative but remain underutilised. Although nudging has already achieved hugely impressive results in sectors like health and finance, it’s only just beginning to be applied with equal force towards environmental goals. Imagine the potential for ESG targets: small changes to infrastructure, defaults, and communication, that make eco-friendly behaviours the easy, default option.
In construction, this means making green building practices, such as energy-efficient materials and sustainable designs, the default when consulting with clients. In supply chain and procurement, this looks like designating eco-friendly suppliers as preferred vendors. In the Energy Sector, this could mean automatically enrolling new customers in green energy tariffs a. And in hospitality, it can be as simple as placing a card in the bathroom, informing guests that “Most other guests staying at this hotel reuse towels”.
Systemic environmental change requires behavioural shifts on both individual and collective levels, and Nudge Theory provides a powerful, under-leveraged tool for driving these shifts. By tapping into behavioural science, we can close the intention-behaviour gap and create sustainable systems that stick, ultimately leading to larger, long-term environmental impacts.
Okay, you’ve sold me, what’s next?
Whether your organisation is working towards a Net Zero target, aiming to reduce emissions by 20% over the next 10 years, or planning to cut energy consumption and operational costs, Caja can support these ambitions directly. Using nudge-based interventions, we can help organisations increase sustainable practices in ways that save resources, cut expenses, and enhance employee engagement.
Behavioural insights give your organisation a competitive advantage, particularly as consumers, investors and regulators demand meaningful ESG data. With behavioural science techniques, you can maximise the impact of your strategy by fostering a culture where sustainable practices are embedded in everyday decisions.
Let’s Nudge the Needle on Sustainability
With ESG targets on the line, nudging presents a promising avenue for driving sustainable behaviours. Our case studies demonstrate our success in applying this approach in various sectors, and we’re ready to help bridge the gap between your sustainability ambitions and actionable results. Let’s work together to embed sustainable choices into daily operations.
The shift to a greener future isn’t just about individual choices, it’s about reshaping systems. Let’s connect and discuss how Caja can bring your ESG goals within reach.
