What does zero carbon mean?

Zero carbon means the necessary and comprehensive decarbonization of all sectors. Fossil fuels such as coal, oil and natural gas will have to be completely replaced by renewable energies (such as solar, wind power and geothermal) – and raw materials in industry, replaced, for example, by ‘green’ hydrogen. The use of waste heat as green process heat is also of central importance as an element of the green heating transition. In a broader context, carbon cycles must be established – for example, CO2 from (industrial) processes and in the atmosphere can be turned into usable resources through the use of technologies such as Carbon Capture and Utilization (CCU), Carbon Dioxide Removal (CDR) and Direct Air Capture (DAC).

Why and to what extent is zero carbon relevant for you?

Humanity cannot afford to allow climate change to continue unchecked if we want to preserve the fundamental basis of life. Societies and economic players must take responsibility.

  • Future viability and corporate sustainability are at stake for all of us.
  • The EU Green Deal – with the associated Environmental, Social, Governance (ESG) and regulatory framework (taxonomy) – mean that companies must start laying the groundwork for a sustainable future today if they want to remain competitive.
  • This process starts with transparent sustainability analysis and the progressive reduction and replacement of fossil fuels and energy production systems with renewable technologies.
  • It also requires the tracking and further development of solutions – leading to entire business processes becoming climate neutral.



The first step towards zero carbon: our approach: a holistic carbon strategy

We help you develop a holistic strategy for carbon neutrality. We work according to the ‘measure, reduce, offset’ principle:

  • First, we carry out an analysis of the current situation and audit your carbon emissions. Based on the Greenhouse Gas Protocol, the focus is on direct emissions from combustion processes, indirect emissions from energy generation, and on all other indirect emissions from business activities.
  • We then examine and define your carbon savings potential and show you economically feasible measures to reduce carbon.
  • If required, we can support you with the implementation, monitoring and reporting of these measures.
Scope 1 Direct emissions within the company

  • Burning fuels
  • Heating and cooling
  • Company fleet
  • Processes

Scope 2 Indirect emissions within the company

  • External energy supply (electricity, district heating / cooling)

Scope 3 All other indirect emissions

  • Business travel (by air, rail, bus, car and taxi)
  • Employee commuting
  • Water consumption
  • Paper consumption
  • Building materials used
  • Procurement of materials, products and services

Elementary: Sector coupling to create an integrated overall system

The effective key to successful implementation of zero carbon is sector coupling: Industry, mobility, heat and electricity are then no longer considered in isolation, but interact with each other. Existing infrastructure is indispensable and must be integrated economically and intelligently.

How are we implementing Zero Carbon at Drees & Sommer?

On the way to becoming a Beneficial Company

As a Beneficial Company, we give back more to the environment than we consume through our business activities. In this way, we make lasting positive contributions to the environment and society, and provide the greatest possible benefit in these areas.

Focus: Strategies for a secure and zero-carbon energy supply

Our energy supply and industrial processes are still based on coal, oil and gas. But it is essential that humanity transitions to zero carbon emissions. This requires all sectors to be optimized – turbocharged by green power and hydrogen. This scale of this transformation will be at least as far-reaching as the three previous industrial revolutions. And in view of the war in Ukraine and its unpredictable consequences, the issue of energy security adds a further dimension of uncertainty.
