The Green Course is developed to inform and to inspire your staff members to contribute to the organisation’s sustainability plans and strategy.

Welcome to the Green Course!

are Sanne and Ramona, and our mission is to enthuse and inspire as many people as possible about sustainability with our online course Building a shared sustainability mindset.

By inspiring employees to adapt a sustainability mindset, businesses can more easily and successfully implement their sustainability plan and goals with support and input of all staff members and departments.

Staff members are one of the most important stakeholders within an organisation. Executing policy and strategy without support from this group is very difficult and ineffective.

Change within an organisation is always difficult, whether it’s a new computer program or taking a sustainable direction. Therefore, we have structured this course according to the ADKAR change model.

“Truly integrate sustainability in your organisation.

From digging heels in the sand to true ambassadors”

Module 1: Oh no! What happened?

In the first module we go way back to find out what happened. The Earth is estimated to have been formed 4.5 billion years ago and consists of many complex ecosystems. In the past 250 years humanity thrived in numbers and welfare, but also started to bring imbalance to these billions of years old ecosystems. In this module we look back at the path that brought us to our current situation

Module 2: Our current situation and climate myths

The second module gives information on the current situation. It explains the Paris Agreement and the different pressures on our planet that we are currently facing such as excessive greenhouse gas emissions. We explain, for example, what CO2 and methane gases are and how they affect our planet.  The nine planetary boundaries are described and explained with clear examples.

Then we tackle a few climate myths and misunderstandings such as; The Earth is heating up by a few degrees, so what? I prefer warmer weather… or the Earth’s climate has always changed, so why is it a problem now?

Module 3: Future road map

When starting this module, you will understand the problems we are facing. In module 3 we explain what we need to accomplish to restore the balance. Important aspects to accomplish this are system thinking and a circular economy. A society where every company takes their responsibility of the complete chain.

In the last part of this module, we look at the predictions and the five scenarios from the latest IPCC report are explained. What will the future bring and how can we influence this?

Module 4: A good end…. 

At the end of this fun and exciting course we share examples of businesses that already made the change to a more sustainable strategy and business operations, and the benefits that they experience.

There is more…

Do you know that feeling when all of a sudden you see things crystal clear? This is what I should do!

We are Ramona Davidson and Sanne Vincenten, founders of The Green Course. We met back in 2014 when we were colleagues working both as account managers for the same client.  A very corporate role, but we always had great interest in the sustainability aspects of the role.

After an intense but very pleasant collaboration and countless long workweeks together, we both got pregnant. After our daughters were born, Ramona started her own business as a sustainability consultant. Sanne remained at the company but in a new role as sustainability manager.

Both experienced a reoccurring issue in their new jobs; to really implement sustainability plans and goals, you need the entire organisation. And to get everyone on board, takes a lot of effort. We expect and know that many of our sustainability colleagues have a similar problem. 

In our opinion you don’t need to be a sustainability expert to understand that our planet is not doing well. Various problems such as global warming have very serious and disastrous consequences if we don’t act fast. Although for some this does not hit home. There needs to be change to keep our lives (and those of future generations) habitable and comfortable. We want to trigger the intrinsic motivation of as many people as possible, to make change easier and faster.

Our mission is therefore: inspire everyone to adopt a sustainability mindset and lifestyle!

Per participant we plant a tree through Trees for All

Every year 3.5 billion trees are lost. With disastrous consequences for people, animals and climate. That’s why Trees for All invest in trees. How? They plant trees and restore existing forests and raise awareness about the need for trees. Close to home, but also further away through sustainable forestry projects in developing countries. The Green Course plants a tree on behalf of each participant of Building a shared sustainability mindset.
