In 2019, Cemasys funded the planting of 150.000 mangrove trees in the Thor Heyerdahl Climate Park in Myanmar. We see this as a unique opportunity to contribute to mitigating climate change and improving the socio-economic conditions of the local community. Planting new forests bind CO2 from the atmosphere; one new mangrove tree can bind approx. 1 tCO2 over a twenty-year period. Mangrove forests are also breeding grounds for fish populations and foster biodiversity and crucial habitats for otherwise threatened and endangered animal and plant species.

Cemasys was one of the world’s 100 first climate neutral companies. We have signed the Climate Neutral Now pledge (UNFCCC) and adhere to the methodology for all our clients that calculate, reduce, offset, and communicate their emissions. Climate Neutral Now is an initiative that encourages the offsetting of emissions by supporting green projects that reduce, avoid, or remove greenhouse gas emissions.

In 2020, we joined the UN Global Compact as a Participant member. The initiative allows partnerships and collaborations in the work needed to reach the UN Sustainable Developments Goals (SDGs). Through our membership, Cemasys participates in regional and international engagements and resource development.


As the only Nordic consulting firm, Cemasys is a long-time accredited CDP (Carbon Disclosure Project) provider and Silver Partner. We receive training and exclusive insight into the CDP’s methodology as well as close support from the CDP staff. This means that our clients receive the very best support from our team who have unique insight into the best practices for responding to the CDP questionnaire.


Through the CDP we are also recognized as an accredited Science Based Target provider. In our collaboration with the Science Based Target initiative (SBTi) we help companies develop ambitious and meaningful emission reduction targets as an integrated part of their sustainability strategy and help develop plans to reach these targets.


S-Hub is an organization that brings together the sustainable business community in Norway and coordinates collaboration and activities, and to build knowledge on sustainability topics. Cemasys has been a member of S-Hub since 2017.

To strengthen our sustainability work, we engage in A Sustainable Tomorrow. It is a modern meeting place where knowledge is spread, and networks are created in order to increase sustainability in business. With the Global Goals as a starting point, new ideas and multidimensional collaboration are generated that lead to increased business value. A Sustainable Tomorrow arranges, among other things, an annual sustainability and future conference to bring together sustainable actors from business, the public sector, civil society, and academia.
