Our Impact Journey
Start of the Journey

In the year 2020, Calisen embarked on its sustainability journey with a pledge to make a positive impact. This marked the beginning of our commitment to creating a more sustainable future for all.

Setting the Foundations

In 2021, we laid the groundwork for our sustainability efforts. We established a set of ambitions that were supported by a comprehensive strategy and policy. This foundation enabled us to take our first steps towards making a meaningful difference.

Collecting the Data

Throughout 2022, our focus was on data collection and target setting. Collaborating with internal and external stakeholders, we ensured the compilation of a complete data set that serves as a baseline for our future goals. This data-driven approach empowered us to make informed decisions.

Taking Action and Beyond

As we step into 2023 and beyond, our emphasis is on taking tangible actions to deliver on our commitments and aspirations. This year will see us translating our data and ambitions into impactful initiatives that drive positive change and create a more sustainable world for everyone.

Our Achievements

Lifetime Emissions Assessment

After assessing and measuring emissions across our processes and supply chain, we now have the actionable data to reduce our carbon footprint.

Expanding Electric Fleet

to reduce our carbon emissions, we will continue to increase the number of zero-emission fleet vehicles and charging stations.
