Cultivating Impact: Exploring the Meaning of Personal Influence

Each one of us strives to make a meaningful difference in our own lives, in the lives of others, and in the world at large. It is essential to recognize that our actions are consequential. They contribute to the dynamics of our surroundings. Yet, how can we ascertain the true impact of our actions? Should we rely solely on subjective feelings or seek evidence of tangible consequences?

HASC Workshops @ the Community Festival

September 30, 2023

HSG Alumni celebrated the Community Festival on Saturday, 30 September for our alma mater's 125th anniversary. We partnered up with two other clubs and co-hosted two sessions:


In partnership with connexHR, we held a workshop on the role of HR for sustainability. Is sustainability a means to recruit Gen Z employees or is it an inherent aspect of HR? After all, sustainability also encompasses a social dimension, and what department could be more suited to address this than HR?

Our second session was a podium on sustainability in real estate, co-hosted with the MBA Alumni Sustainability Club. Our experts shared their understanding of what sustainability in real estate means and debated various aspects - from which building materials we should use and what building standards we should apply, over how real estate can be managed sustainably to whether we should renovate existing or build new houses. 

You can see some impressions of the sessions below and you can find all the pictures of the Community Festival here.

Healthy and sustainable convenience food by FELFEL 

May 11, 2023

You have probably heard of FELFEL. They are a popular start-up of HSG Alumni, so they are frequently featured in our alma mater's communication. They provide employees at offices without a canteen with tasty meals, often partnering with known food brands like Tenz, Paul & Lulu or Tibits.

As part of their sustainability commitment they source from local family enterprises, strive to provide healthy menu options and delivery their meals in recyclable boxes. Of course nobody is perfect, but FELFEL strives to improve its sustainability performance. Hence they are d
oing a full sustainability analysis of their business and they agreed to share and discuss the results with us! FELFEL guided us through a company visit and shared with us their newly developed sustainability report with their main initiatives. See some impressions of the event below.

Insuring for a changing climate with 

March 14, 2023

The insurance industry is highly affected by climate change, as natural disasters occur much more frequently and result in higher claims payments. It is thus essential for insurers to adapt their strategies to changing circumstances and to promote the mitigation of and adaptation to a warmer climate among their customers.

We were thrilled to discuss the arising challenges faced by the insurance industry with Linda Freiner, Group Head of Sustainability at Zurich Insurance, and to learn about Zurich's sustainability strategy.  Linda Freiner explained how sustainability is embedded in the company’s strategy. She elaborated that, as part of their commitment, they take on non-sustainable customers and help them on their sustainability journey, rather than turning them down. Next to the engagement in their core business, Zurich supports projects on several topics, such as climate adaptation and social equity, through the Zurich Foundation.
After their insightful input, the HASC members and Zurich employees networked over an Apéro richer.


See below some pictures of the event.

Valentine's Day Stamm @ Kasheme

February 14, 2023

Yes, you read right, we hosted a Stamm on Valentine's Day. And no, there wasn't be any speed dating. (Although we had some fun debating the idea.) We organised a regular Stamm, where everyone - single or taken - was welcome.

Online event: Plastic is evil! Or is it?

January 18, 2023

We kicked-off this new cycle of events with Kim Bauer, member of our Board, working for Aldi Suisse. She is responsible for all things packaging and explained that packaging only represents 4% of total product's greenhouse gas emissions. Nevertheless, packaging is a hot topic in our society and it is much more complex to address than one might think. In fact, Kim explains, it is a lot about changing customer behaviour - depending on how many times you use it, a cotton bag might be much worse in terms of its carbon footprint than a single-use plastic bag. We had lively discussions about how to solve this problem. Of course, recycling is important, but is it really as efficient as we hope? In the end, it all comes down to one thing: We have to significantly reduce the amount of plastic waste that we generate.

November Stamm @ Kraftwerk

November 16, 2022

As one of our aims is to facilitate networking and exchange among sustainability-interested peers, we want to establish our Stamm as a regular get-together to meet new people and catch up with old acquaintances. Thus, we plan to schedule a Stamm every other month.

This Stamm took place on Wednesday, 16 November at 7pm at Kraftwerk (Selnaustrasse 25). It was great seeing ou all there

Are you hungry for change?

October 27, 2022

The planted.experience was a blast!  A big thank you to everyone who joined the factory visit - and above all to Valérie for giving us a tour.

It was apparent from your numerous questions regarding positioning and production that there is a general curiosity and desire to learn more about the growing market of plant-based sources of protein. Thanks to our well-versed guides we are confident that you went home with many new insights and an appreciation for their innovative production technologies. 

The mix of attendees also showed the potential of plant-based alternatives for the environment. As not all of us are willing to give up meat completely, the availability of products with similar taste and texture can help meat-lovers to replace some of their consumption with plant-based alternatives. We hope the factory visit planted an idea ;)

Planted produces delicious plant-based proteins including Schnitzel and chicken chunks, focusing on the perfect bite. Inspired by nature, the company pioneers a novel biostructuring approach that combines protein structuring and biotechnology. Using various proprietary technologies, Planted designs and structures alternative proteins in any size, shape, and fibrous texture and is convinced that biostructured proteins will outperform animal meat in the future in terms of taste, sustainability, health, efficiency and price.

Visit @Resilux

April 6, 2022

We had the exclusive opportunity to visit Resilux, a leading company in the PET packaging industry. CEO and HSG Alumna, Jana Walker, welcomed us personally. We received a guided tour on the topic of circular economy on-site in Bilten and were able to take a closer look at the bottle-to-bottle PET recycling technology. In the end, we had time to network over a FELFEL snack.

What do doughnuts have to do with economics?

March 24, 2022

Developed by University of Oxford economist Kate Raworth, doughnut economics is a visual framework for sustainable development. The framework combines the concept of planetary boundaries with the complementary concept of social boundaries in a doughnut-shaped model - hence the name.
The main goal of the new model is to re-frame economic problems and set new goals that meet all twelve social foundations without overshooting any of the nine ecological ceilings. 

In this online event, we received an introduction to this framework by Dave Brühlmeier, certified practitioner of the Doughnut Economics Action Lab. He elaborated on: What does it mean? How can its goals be reached? What role do companies - and we as employers and employees - play within this framework?
Afterward, time was given to discuss the theory, its practical applicability as well as advantages and challenges of doughnut economics. We hope you all had a sweet time during this online event.
