Can Bushido (Samurai Code) help small businesses achieve environmental sustainability?

As the Chief Operating Officer of a small construction company, I’ve often faced the challenge of making environmental sustainability part of our daily work. Adopting eco-friendly practices can feel daunting for smaller businesses, which don’t have the resources of larger firms. However, I found unexpected inspiration in Bushido, the ancient samurai code.

Bushido emphasises values like integrity, discipline, and loyalty — qualities that resonate with me as I guide our company toward a more sustainable path. While the samurai applied these principles in their own way, modern businesses can use them to shape responsible, environmentally conscious operations, particularly in industries like construction, where sustainability is often seen as costly or complicated.

Here’s how I think Bushido can help small businesses make meaningful environmental progress, even with limited resources.

Gi, or rectitude, is about making the right choices, even when they’re difficult. For small businesses, this means committing to real environmental action rather than making efforts that look good on paper but don’t make a real difference.

At T Newman Ltd, integrity in sustainability means being honest about our efforts and prioritising long-term gains over short-term cost savings. Whether it’s reducing waste on-site or sourcing locally from eco-friendly suppliers, we focus on actions that truly matter. This means avoiding greenwashing and sticking to genuine efforts that align with our values.

Small businesses can build trust by staying true to honest practices and showing clients and stakeholders that they are serious about environmental responsibility, even if it takes time.

Yu, or courage, was a key trait of the samurai. Small businesses need the same courage to embrace sustainability, especially when resources are tight. Being bold doesn’t mean changing everything overnight — it means taking small, deliberate steps toward bigger goals.

In my role, I’ve learned that starting with smaller initiatives, like using sustainable materials, reducing waste, or switching to energy-efficient equipment, can lead to significant long-term benefits. Making these changes takes courage, especially when the upfront costs are higher, but the long-term impact makes it worthwhile.

For small businesses, courage is about understanding that you don’t need to do everything at once. Start where you can, and expand as resources allow.

Jin, or benevolence, reminds us that true sustainability is about caring for people and the environment. As a small construction company, we have a duty to reduce our impact — not just for compliance but for the greater good of our community and future generations.

This principle has led us to adopt practices that go beyond basic regulations. For example, we’ve worked to reduce the carbon footprint of our projects by using local suppliers and energy-efficient equipment. We’ve also committed to recycling and reducing waste. These actions may seem small, but over time they build a culture of environmental stewardship.

Benevolence in sustainability means recognising that our actions have long-term effects. It’s not just about profitability; it’s about building a business model that makes a positive difference.

Rei, or respect, is a core value in Bushido, and it can be applied to respecting the environment in business. For small businesses, this means understanding the natural systems we rely on and working in harmony with them.

At our company, we approach every project with care for the land, materials, and energy we use. This has led us to seek out more sustainable materials and implement practices like efficient site management to avoid unnecessary waste.

Respect also means working with like-minded suppliers and partners. Building relationships with those who share our values strengthens our sustainability efforts and promotes greener practices throughout the industry.

Makoto, or honesty, means keeping your word. In terms of sustainability, this means aligning our actions with our promises. Although it is simple to declare that we are going green, actual, quantifiable actions must support those declarations.

At our company, we ensure sustainability is more than just a marketing slogan — it’s part of our business strategy. This means regularly evaluating our practices, setting clear goals for reducing our impact, and being open with our clients about our progress.

Makoto is about being honest with yourself and others — admitting where there’s room for improvement and celebrating successes.

Meiyo, or honour, was about leaving a lasting legacy. For a small business, sustainability is about committing to a positive impact that lasts beyond profits.

In construction, where environmental impact can be significant, we’ve adopted practices that aim to reduce our footprint — not just for today, but for the future. From sustainable sourcing to energy-efficient operations, we strive to make choices that benefit both the industry and the environment.

Small businesses may lack the resources for immediate large-scale changes, but by integrating sustainable practices now, we can create a legacy of responsibility for others to follow.

Chugi, or loyalty, is about staying dedicated even when it’s difficult. Small businesses often face obstacles on their path to sustainability, like financial pressures or scepticism from others.

In our company, we’ve made tough decisions to stay true to our sustainability goals, even when it would have been easier to take shortcuts. This commitment has kept us on track, and over time, it’s made us a stronger, greener business.

For small businesses, loyalty means sticking to your sustainability goals, even when progress feels slow. Every small step counts.

Bushido offers timeless principles that can help small businesses embrace sustainability. Even with limited resources, we can make progress by adopting values like integrity, courage, respect, and loyalty.

Bushido is a reminder that sustainability is about mindset, not resources. By taking small, deliberate steps toward a greener future, we can create a business that not only survives but thrives — leaving a positive legacy for the environment and future generations.
