We promote sustainable business

We would like to help companies as much as possible so that the steps taken will be easy, innovative and will allow the creation of new business opportunities and preservation of competitiveness. 
We are aware that it is difficult to know where to start how to take into consideration the climate changes and introduce sustainability in your business. Due to the large scope of challenges in front of us, the lack of information and limited funds to start a change, many of them are not sure how to act. Whether you are at the start in the field of sustainability or you just need some kind of confirmation that you are on the right way, we can suggest you what steps you can take already today to make a progress as fast as possible.

Green Star

Green Star is the first certificate in Slovenia for introduction of sustainable aspects and climate action in the company business. It is a tool to help economy on the way of green transition and in reaching the climate neutrality.

Green Star

Green Star Club is designed for the exchange of experience and practices in the field of green transformation and sustainable business among the recipients of the Green Star Certificate. The meetings take place at the seat of recipients, who are also CER members.


We look for new and green solutions which decrease the use of energy and materials, reduce waste, increase the use of clean energy and are more energy efficient. Moreover, we present them with the purpose of acceleration of cooperation and integration with other members.


Through the various awareness-raising campaigns, we bring closer the recent and professional issues to a wider public. In the past, we ran a national campaign For a better indoor air quality and Champions of green transformation.


We take part in various European projects, through which we enable the development of new green services, products and technologies to our members. At the moment, we take part in a project SmartMOVE, addressing the challenge of sustainable mobility and DESIRE, which would like to create more sustainable, integral and beautiful premises at the locations across the EU.


We are a partner of various international organizations enabling our members to access the international information and involvement in the international activities. On the local level, we cooperate with foreign chambers of commerce and embassies.

Green Star certificate

promotes the sustainable business and climate action

We encourage companies to start to collect, measure and report on emissions. We invite you to join holders of the Green Star Certificate and gain an insight into your own business, recognise areas where you could improve and create a positive reputation among your shareholders.

We have developed the Green Star Certificate in order to empower companies and encourage them to create higher added value with a lower impact on the climate and environment.



Awareness-raising campaigns

Through various awareness-raising campaigns we would like to increase the knowledge and general public awareness about sustainability and similar issues, change shareholders’ attitudes towards the seriousness of climate changes, and empower companies and general public to take action and change their habits. 

We cooperate with various experts as well as companies that would like to actively move towards cooperation and present their experience, good practices and innovations in the field of green technologies. 


We promote inclusion in EU and national projects

We take part in various European projects, enabling our members to develop green services, products and projects. 

At the moment, we are taking part in three projects, namely SmartMOVE, DESIRE and KCDM 3.0.


Opinions of our members
with whom we are writing green stories.

  • With CER and our business partners, we are constantly searching for and developing new solutions in the field of sustainable development. We encourage and promote good sustainable practices that contribute to reducing the carbon footprint and bring a better future for the environment. We see CER membership as an exceptional opportunity to share experiences, knowledge, and innovative approaches to identify new opportunities for a sustainable future.
    Miha Mermal, Chief Marketing Officer and Chief Sustainability Officer, BTC d.d.
  • As a society, we are facing many environmental and sustainability challenges. If we want to successfully address them and contribute to active changes, we need to be connected and decisive. CER is the only association in Slovenia that covers a broad spectrum of sustainable activities. Therefore, the effects are not just aggregated but rather multiplied. And this is what makes CER unique and brings exceptional results.
    Marko Lukić, CEO and Owner, Lumar IG d.o.o.
  • ELES has developed a sustainable strategy up to 2050, where we balance the objectives of the company's essential capital development and prepare the company to respond to changes in the social, business, and natural environment. We see CER Sustainable Business Network as a promotor of green technologies, green innovations, and circular economy in Slovenia and beyond. This is why ELES decided years ago to become an active member of CER.
    Jana Babnik Gomišček PhD, Advisor to CEO, Eles d.o.o.
  • Over the years of its existence, CER has truly established itself as a beacon for energy efficiency, and more recently, as an advocate of a comprehensive approach to sustainability. Through its activities, it has a positive impact on legislators, politicians, companies, and end users.
    Saša Bavec, Managing Director Systems Division, Knauf Insulation
  • CER has undoubtedly become the central driver of the green transition in Slovenia. It unites the most advanced Slovenian companies with research and academic spheres. The knowledge and experience of its members and its professional team make CER the key interlocutor for decision-makers on the national and local levels and enables the organization to join the discussion on all relevant social topics. Because of CER's active role in the green transformation, I do not worry about the future of Slovenia, despite many hurdles that still need to be overcome.
    Slavko Ažman, Head of Business Management, Porsche Slovenija
  • CER is an association of Slovenian companies that invest the most in sustainable development and the green transition. CER enables its members to speak unanimously to decision-makers and search for the best solutions and policies that could make Slovenia one of the most aware and advanced countries in circular economy and in the fight against climate change.
    Bojan Stojanović, EU Project Manager, Petrol
  • Decarbonization of the economy, energy efficiency and the transition to renewable energy sources can only be achieved through integration, cooperation, and strong partnerships. CER in particular is an excellent platform for companies from different sectors to combine knowledge and experience and, thus, develop sustainable business models. The NLB bank, which is also the first financial institution to become a CER member, strongly supports sustainable development and will therefore continue to cooperate with CER Sustainable Business Network in paving the right way for the future.
    Andrej Lasič, Member of the Management Board, NLB d.d.
  • Today, after a 12-year journey, CER Partnership as a sustainable business association represents the first and the most prominent advocate and promoter of the green economy and the opportunities that investments in the green transition bring to our society and economy.
    Gregor Benčina, President at EBS Group
