Cemasys Climate Park

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.

Climate Neutral Now

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.

UN Global Compact

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.

CDP Accredited Provider

As the only Nordic consulting firm, Cemasys is a CDP silver climate change consultancy and SBT partner in the Nordics and US. 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.

A Sustainable Tomorrow - Best at meetings that make sustainability happen

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.
