Special Announcement:
Welcome to RSI's new website

Welcome to our new RSI website, launched October 1st, 2020.

RSI is proud of its accomplishments and contributions to the field of risk science over the last fifteen years, and is pleased to be able to share its experiences with our many clients and stakeholders worldwide.

We hope that our new website will help you appreciate the world of risk, and what RSI can do to help you in understanding, managing and communicating risk.™


Understanding Risk

Risk is real. It can appear suddenly, or gradually over decades. Being prepared, and understanding the best course of action is not an option, it is a responsibility.

Managing Risk

Risks do not resolve themselves. Regardless of whether a risk is imminent or long-term, managing risk wisely and rationally is critical. Effective risk management is the key to risk solutions.

Communicating Risk

When people are at risk, what you tell them matters. Knowing what to say, how and when, is as important as gaining their trust with sincerity and evidence. Communication is part of the solution.

Understanding, Managing and Communicating Risk 24/7

In addition to individual services, RSI provides integrated risk retainer options, offering clients the benefits of ongoing, on-call risk expertise.

What is risk?

Is it what we tell our children to avoid, before we tell them how many people die from not wearing seat belts? Is risk a scientific discipline like epidemiology,  toxicology or clinical science? Is risk what good leaders factor into all their decisions?

Perhaps risk is all of the above, as well as anything that leads to harm including loss of life, loss of livelihood, loss of commercial viability, even loss of peace.

Can something be done about risk? Can lives and livelihoods really be influenced, even saved, by experts in risk science working with data, models, theories or even expert opinion?


| risk |

uncertainty, precariousness, gamble, peril, threat, a situation involving exposure to danger, a situation regarded as likely to turn out well or badly without certainty, a process or strategy lacking sufficient evidence and/or planning

endanger, imperil, jeopardize, take a chance with, advance without precaution, act or fail to act in such a way as to avoid something unpleasant, unwelcome or unsafe

'at risk' – exposed to harm or danger, as in: "23 million people in Africa are at risk from starvation." | 'take risks' – to take a chance, as in: "Often in life you have to take risks to make progress."

safety, certainty, security, preparation, caution, mitigation, comfort, benefit

In the real world, risk is anything and everything that lacks certainty. Every one of us, every parent, every citizen, every company, government or organization lives it every day.

Understanding, Managing and Communicating Risk is more than a tagline, it is at the heart of what RSI does, and how it does it.

For years, Risk Sciences International has laboured to build the best team, keep their knowledge current, challenge them with demanding projects, and keep them grounded in real-world needs. RSI understands that when dealing with risk, there are consequences to poor choices; RSI staff know this and are constantly reminded of it by the very work they perform.

From day one, the challenge RSI set for itself was to understand risk by employing specialized experts able to deliver solutions across sectors. RSI experts hail from multiple sectors ranging from public health, to urban infrastructure, to simulation and modeling, to communication, and more. The company includes both academics and highly technical staff. Its tools are geared to take on any challenge. Whether the project requires the most advanced algorithms, the most thoughtful risk policy analyses, or the most impactful risk messaging, RSI experts understand what is needed.

Understanding risk, diagnosing, simulating, surveilling... all these are essential, but so too is the ability to accompany a client through the thick of the storm. Beyond understanding, RSI helps manage risk. The company has the operational expertise to guide and work with clients who have no time to waste. The team is both motivated and trained to respond day and night, at a moment's notice. Fortunately, many risk events are not solved by racing against the clock, but because some are, RSI is ready. Whether the project calls for a new risk prevention strategy, a convening of stakeholders, or the development of a technological solution, RSI delivers.

Increasingly, communication is a critical component of a risk response. From the simplest news release to the most complex international campaign or a highly technical communiqué, RSI has the expertise and experience to make a difference. Of note, is RSI's ability to deliver substantive content. Unlike traditional risk communication agencies, RSI's communication experts have the benefit of an in-house scientific team. Using evidence is the foundation of building trust, RSI knows how to gather and use that evidence to advantage.

Understanding, Managing and Communicating Risk 24/7

RSI believes strongly in the added value of building long-term relationships. To this end, RSI has established extended ties with key clients, whereby relevant RSI core services are delivered within the framework agreement of an annual retainer package supplemented, as needed, by individual projects. This annual approach guarantees that RSI is ready-to-respond at a moment’s notice, without the wasted time associated with getting-to-know the client when a project begins.

Combining a retainer with as-needed services is the ultimate form of risk preparedness.

More than ever,

More than ever,
risk science matters.

Our world is constantly threatened by natural and climate disasters, public health challenges and pandemics, infrastructure failures, chemical spills or conflicts. There is risk in everything we do as individuals, companies, organizations or governments. It is essential that all those working in the field of risk science – including RSI – intensify their efforts.

In our own lifetime, the Bopal disaster, Chernobyl, 9/11, hurricane Katrina, the Tōhoku earthquake or more recently the COVID-19 outbreak, have all taught us that you can never be too informed, too ready, or too willing to take on the responsibility of mitigating risk.

It is our common duty, to do everything in our power to improve quality of life and life expectancy by better understanding, managing and communicating risk.

Before Tōhoku earthquake After

The challenge: On March 11, 2011, the 9.1 magnitude Tōhoku earthquake, and ensuing tsunami, hit Japan. It was the most powerful earthquake ever recorded in Japan. The tsunami reached heights up to 40.5 meters (133 feet) obliterating most of the region. The wave traveled at 700 km/h (435 mph) and reached 10 km (6 mi) inland. Officially, there were 15,899 deaths, 6,157 injured, 2,529 missing, and a total of USD 360 billion in damage.

"We must move away from assessment and management to anticipation and prevention."

Daniel Krewski

The event also caused a level 7 meltdown at the Fukushima Daiichi nuclear power plant that took several months to stablize.

The response: Four years later, in March 2015, UNISDR – the United Nations International Strategy for Disaster Reduction – informed by risk scientists, held its World Conference on Disaster Risk Reduction in Tōhoku. The conference produced the Sendai Framework, a document to guide efforts by international development agencies to act before disasters instead of reacting to them after the fact.

Risk science matters.
