Sustainability in Carl C

Carl C. A/S is part of the value chain for developing infrastructure for renewable energy to ensure a stable future for the next generations. However, the process requires a construction phase. This phase involves deforestation, heavy machinery, safety-related risks, etc., where ESG provides a common designation to gather a company's responsibility in one word.

With ESG (Environment, Social & Governance), the impact of a company's decisions on the world is considered, where the three pillars create the criteria for evaluating a company's sustainability performance.

For Carl C. A/S, sustainability is becoming part of our culture to make responsible decisions and ensure the best solutions for our customers. Therefore, the concept is integrated and worked on at all levels of the organization. The board decides the strategic direction and selection of goals, while data is collected at every project.

The process of becoming more sustainable requires the entire organization to work together. Especially the people working in production have relevant expertise in knowing how we can optimize our work and integrate new initiatives. Therefore, the report and our sustainability progress are based on a collective corporate effort to be the preferred supplier in the industry.
