We’ve just passed the 10th anniversary of the financial crisis. What’s your view of the banking sector and what happened 10 years ago?

What’s at the heart of banking? Understanding your risk and investing and lending money to private initiatives. What shocked me most in 2008 was that bankers didn’t know what was on their balance sheets. They didn’t understand the products, let alone understand the risk involved.

It seems to me there were some banks in the Netherlands, the United Kingdom and Germany that were run by amateurs. These amateurs spoiled the ethics of the profession, didn’t behave professionally and neglected their duties.

So what role should a bank play?

A bank is an institution serving society. It collects money, providing a safe place for people to save, and it enables entrepreneurs and investors by lending money for business to take place. A close relationship between banks and the real economy is of essential importance.

On the other hand, we now have this other debate on how banking can contribute to sustainability. Banks are called upon to do so, with challenges such as the United Nations’ Sustainable Development Goals (SDGs) and the national strategies for the Paris Climate Agreement.

We’re starting to get somewhere. We recently brought together the big banks in the Netherlands with a joint letter to government to encourage it to do more. There is a big conversation in my country around the target to halve CO2 emissions by 2030, and the government is responding to this, which is huge. It makes me optimistic when I see this isn’t only an issue for Triodos Bank.

How is Triodos Bank advocating for change in banking?

Our strategy is twofold. Firstly, we’re a bank focused on the real economy, taking into account people, planet and prosperity. So, we have a holistic approach focused on what is of benefit for the communities we finance. That is our basic approach and we have practised it for almost 40 years. This allows us to set an example of how to behave like a modern, socially-oriented bank, with a professional and real approach.

Secondly, advocacy. We bring proposals on how to change the financial system into the conversation. As a European bank, we are very much engaged in discussions in Brussels, on fiduciary duty, disclosure, defining sustainable finance, and other matters.

The basic paradigm that the financial sector is neutral is a lie. Society is starting to wake up to what the banks are doing with its money. The SDGs, and climate risk in particular, must somehow be integrated into financial regulations around the world.

Many people think it’s up to politicians to sort this out. What’s your view as an ex-politician?

At Triodos, we offer people the opportunity to be part of the solution, by opening a current account or a savings account with us. I’m aware that in many countries citizens are quite skeptical about what politics can do. The best answer I can give to that is this: don’t leave politics to other people who don’t engage. The best thing we can do is to step up and participate.

Business, the banking industry, NGOs, citizens and communities can all make a difference, but don’t leave politics to others. Step up if you’re not satisfied with the way politics are run in your country. That’s definitely a motivation for me. I want to be involved, because good politics impact on the course society is following. In my political years, I came across amazing people, good visions, and great ideas, as well as the opposite. But it was one of the best times of my life.

How do you react to the idea that being environmentally friendly is something only for the rich?

It isn’t and shouldn’t be the case. If we say that environmentally-friendly options are elitist, then we ignore the whole issue of how we exploit our planet and we may not act in time to combat climate change.

I think this is the reason why a holistic approach like the one from Triodos Bank is of great importance. I’ve never considered Triodos to be just a green bank. I think social inclusion and a fair distribution of wealth in society also coincide with our green agenda, creating opportunities to finance the fight against climate change. That is why in the Netherlands I was a member of parliament for the so-called Green Left, because these two stories belong together – a fair distribution of wealth is a very basic condition for a successful green economy and society.

What’s your dream? Where do you want to see Triodos Bank or banking in 10 years?

My dream is for Triodos to be ten times bigger than now, not because of direct growth but because we’ve inspired other banks, who use our model to do business. They’ll also look at the level of engagement of our employees. I think that there’s almost no company that equals that level. We have to be modest, but since joining I’ve seen work that Triodos Bank can feel very proud of. A bank is a people’s business, not a model, not a computer. If we keep that, bigger, institutionalised banks will be inspired by our heritage. If they do that, then we’ll make a significant impact.
