Raising the bar for sustainable events

By Louise Thomsen

How often do we as event coordinators ask ourselves: how can I minimize the plastic use, the waste, the paper? I could also reverse the question and ask: Could we imagine a smarter, more efficient and even more inspiring new way to host events?

Copenhagen Business School hosts a significant number of conferences and other events throughout a year and all carry the opportunity to be managed more sustainably. But, what makes an event sustainable? In June, the Sustainable Consumption Conference hosted by the VELUX Endowed Chair in Corporate Sustainability at CBS became the first pilot conference for implementing sustainable initiatives at a bigger event at CBS.

Hosting events is a wasteful affair

We all know exactly what to expect when attending a conference. You receive a name tag when you register, which you usually throw in the waste bin when you leave. You get a plastic bottle of water, and when you are done with that, or even before you are done, you get another one. You get the conference programme and the participant list which you look at a couple of times before that goes into the waste bin. Often printed in colour.

Now, imagine attending a conference with no plastic bottles, no paper, no meat, and no food waste. Imagine, how this conference would increase the level of awareness, communication and engagement between the participants and the hosts. And ignite fruitful discussions because we would realize, how much we can actually achieve with little changes in our everyday lives.

Sustainability taken to new heights

On June 27-30, more than 200 scholars and policy practitioners participated in an international conference on sustainable consumption at Copenhagen Business School, The conference topic Sustainable Consumption naturally raised the question how a sustainable conference could look like at Copenhagen Business School? No attempt at all to satisfy the conference’s title would be more than hypocritical.

In order to make sure that the sustainability initiatives implemented at the conference were the most sustainable solutions and had a high impact factor, the conference organizers allied themselves with a group of students from the Danish Technical University (DTU) who were doing a course on Life Cycle Assessments.

The students received 2 cases

  1. How should the conference supply water?
  2. How should the conference be catered?

Over the course of 4 months, the DTU student teams collected data from CBS and carried out life cycle assessments taking into account various impact factors such as production, transportation, use and disposal etc. Based on the results, all conference meals were vegetarian, and all conference participants received one glass bottle that could be filled from water dispensers throughout the entire conference.


The conference participants also received information about the sustainability initiatives that they could expect prior to the conference. The findings from the life cycle assessment were communicated on posters and on the back of the staff t-shirts. All conference staff engaged with the participants and assisted with water bottles and waste sorting. Furthermore, the conference participants were continuously encouraged to share feedback and discuss the attempts made with each other and the staff.

Implemented sustainability initiatives at the Sustainable Consumption Conference

  • Each conference participant received one reusable glass bottle, which replaced single-use plastic bottles for the distribution of water throughout the conference.
  • Every meal served at the conference was vegetarian, reducing the environmental impact of the conference’s catering by 44% compared to meat-based meals.
  • Participants were asked to sort their waste throughout the conference, using designated bins for paper, plastic, food, and general waste.
  • The conference was largely paperless. Programs and other general information were made available in ways that reduced the need for paper, such as printed posters and an app with, among other information, the timetable.
  • The lanyards for name tags were made from recycled polyester, and both name tags and lanyards were collected for reuse after the conference.
  • Food waste was minimized by asking participants to give notice in advance about which meals they were going to participate in, and any leftover food was brought to a nearby centre for homeless people.
  • All conference staff wore a sustainable and organic cotton t-shirt with key sustainability messages on the back.

Invitation to a learning journey

When hosting an event at CBS, you are in touch with many different stakeholders who have procedures on how to efficiently meet requests on catering, waste handling, or cleaning. This means that it must be a collaborative effort if you want to change the existing structures. Engagement and communication are key.

We should not get carried away by the belief that the easiest solutions to implement will necessarily be the most impactful or more environmentally significant than our starting point. There is a big difference between solutions that carry a high degree of reducing CO2-emissions (real impact), and solutions that have the purpose of creating awareness. Both aspects are highly important. However, we should be aware of when we spend resources on one or the other and communicate this clearly.

I want to invite you to think about how we can improve our ecological footprint when we host events at CBS and elsewhere. As you will soon learn, there is no such thing as a “sustainable event”. However, there are well-founded decisions and much to learn if we dare to ask the question:

How can we raise the bar for sustainable events?

Creating a whole conference to have a significantly reduced amount of waste, use of paper and plastics is a big challenge. But many people also wonder, what they can do as individuals to limit climate change, if there is anything at all.
This issue is treated in another edition of the Sustainability Seminar Series at the department of Management, Society and Communication at CBS.

Behavioural change in the work environment: a first review on MSC’s sustainable food policy.

By Jan Bauer.

  • MSC reviews six months of its sustainable food policy
  • Setting defaults can be highly effective
  • Guiding principles for the “right” defaults are not always easy to determine

During the summer 2017, the Department for Management, Society & Communication (MSC) at CBS hold a competition among its members to come up with ideas to foster sustainable behaviour within the daily work-life of the department. In addition to talking the talk in lectures and research, MSC hosts the CBS center for Corporate Social Responsibility, we also wanted to walk it.

Among many interesting submissions, the newly founded sustainable infrastructure task force (SIT) awarded the best idea, based on the potential impact and the feasibility of application within MSC. An idea to reduce the consumption of meat was declared as the winner. According to many studies, the reduction of meat reduces CO2 emissions and is associated with various health benefits.

Despite this evidence, banning meat in the department would have certainly and rightfully created substantial backlash. Banning meat would have unlikely been supported by a majority of the department members or its leadership as it can be arguably considered as an overly strong infringement of individual freedom.

Behavioural policy and the power of defaults

Based on a behavioral policy approach, the new food policy, publicly discussed in a department meeting and implemented in October 2017, ultimately changed the choice architecture of the way people order meals for meetings and events. For a trial period of six months, all meals became vegetarian by default; meaning that people get a vegetarian meal unless they actively opt-out and order a meat-based dish with a short email reply or by ticking a button (see example from a recent workshop invitation).

This idea is based on the principle of libertarian paternalism, which aims to steer peoples’ behaviour without restricting the freedom of choice and has been famously advocated by our colleague Cass Sunstein.

The power and controversy about purposefully setting defaults is often discussed in the context of organ donation. There is little doubt about the fact that people’s inertia to register as a donor can be linked to preventable deaths under the opt-out rule. The Netherlands recently change the default on the issue, but not all countries are expected to follow their example.

Predominant support for a sustainable default rule

The trial period of our food policy helped to understand the difficulties of implementing such a policy, e.g. what to do when you cannot ask participants. But it also aimed to collect data on how many vegetarian and meat-based meals were ordered. After the end of the trial period, a survey was conducted to elicit peoples’ attitudes towards and experiences with the policy.

More than 90% of the self-reported food orderings were vegetarian and the survey revealed that a majority supports to expand the policy beyond the trial period. However, the policy was not exclusively received with praise. Different concerns were raised about the policy, including the perception not feeling free to publicly speak up against such an initiative aimed and officially framed to “save the planet”.

Guiding principles: scientific evidence or democratic process?

I am confident that this pilot project will resolve its remaining issues, but the process itself has been a valuable learning experience and sparked some reflection. One issue is the rather simple question on what guiding principle should the default be selected in such an example. Two ideas come to mind instantly: assuming there is corporate interest in the health of employees and low CO2 emissions, the scientific evidence suggests that the vegetarian default should be the preferred way. However, decisions based on naturally broad scientific claims might miss important case-specific aspects, neglect the (corporate) culture and individual preferences.

Alternatively, setting the default by a democratic process might suffer from limited debate for such a morally loaded topic and individual biases against the abstract value of one’s own long-term health or reducing global warming. In principle, the aim should be to maximize overall welfare and nudge people to be “better off as judged by the themselves”. For reasons outlined above, it is not always easy or even fully clear, how and when individual judgement of such a policy should be assessed.

Judgement at the right time

When it comes to the food itself, having the light, vegetarian meal could be judged as less appealing before or during lunch when being extremely hungry, but evaluation might already change shortly after the meal. Reflecting on a meal in a satiated state can alter the importance of different aspects. Research suggests that hunger shifts preferences towards more palatable and less healthy foods, but also repeated exposure to a specific food increases preference for it. Hence, only 30 minutes could make all the difference, but potential benefits to health and environment might manifest in 30 years and only by then alter retrospective evaluation of such a policy.

Even though there is no natural default, most people like eating meat despite potential adverse health effects, including myself, which makes justifying any default rule difficult. In our case, all approaches we tried point towards the same result, which makes us hopeful to do the right thing. A decision to prolong the experimental policy by another year was recently made in the Department Forum. However, it is important to keep in mind that at its worst, this specific policy presents a die-hard meat lover with a vegetarian meal that he forgot to opt-out of – a hopefully rare event I am nevertheless sorry for.
