Our mission statement

Our mission is to encourage, motivate and activate Slovenians towards a sustainable, healthy lifestyle that “gets into our blood” and becomes our new habit. Through our daily choices, we are responsible for 72% of the world’s greenhouse gas emissions. To reduce them, we need to change mindsets and habits about diet, mobility, consumption and the way we live. Our aim is to help individuals adopt positive and healthy behavioural patterns for a sustainable lifestyle.

How to change your lifestyle? Easy, you only need 21 days!

Lifestyle change takes time and a high level of motivation. Medical research and professional literature state that we can build a habit in 21 days and make it part of our lifestyle in 90 days. Build sustainable healthy habits through 21 day cycles presented through sustainable challenges that are delivered through useful content over 90 days.

Do you know what your carbon footprint is? Do you know how to create a sustainable lifestyle?

We offer workshops on sustainable development. The aim of the workshops is to encourage individuals to change their habits towards more sustainable eating and consumption behaviour, mobility and lifestyle. To make it easier to establish new, sustainable and healthy habits, the Institute will also organise a 21-day sustainability challenge together with our partners, sustainable companies. The Sustainability Challenge will encourage participants to eat healthily, engage in sustainable mobility, take part in sporting activities and take responsibility for the environment. By actively participating in the 21 Days Sustainability Challenge, you will be able to access attractive prizes from our partners and will be more motivated to build new habits.

I am first a proud mum of two beautiful girls, then the founder of Sustainable Challenge 21, a Master in Development Management and an internationally certified yoga teacher. Despite a long career in development in the financial industry, my life today is dominated by my passion for yoga and my desire to help individuals build positive habits, a strong self-image and a healthy, sustainable lifestyle.

Patricija Kožuh
Master's degree in psychosocial support from the Cognitive Behavioural Approach, Faculty of Applied Social Studies in Nova Gorica

During my studies, my desire to nurture the mental and spiritual world of human beings opened the way for me to explore two practices that are very popular and interconnected today – mindfulness and compassion. In particular, the meditation retreats, the participation in the design and delivery of the mindfulness courses, the psychotherapy and the professional and compassionate support I received from the teachers during the training sessions have been valuable experiences for me. Recently, however, my heart and eyes have been reopened, above all by my fresh role as a mother and by the everyday dynamics and charms of family life.

Miha Lukanc
Bachelor's degree in economics, Faculty of Economics, University of Ljubljana

I am a proud dad to a 13 year old son and a 10 year old daughter. I am a passionate sportsman who much prefers to be on a bike instead of a car.
