Sustainability in healthcare: from ambition to action

BLOG - 07 august 2025

The healthcare sector faces a double challenge: providing high-quality care and reducing its ecological footprint.

Accounting for no less than 5% of total CO₂ emissions in Belgium, healthcare (including hospitals, residential care centres, preventive medicine and outpatient care) is undeniably a polluting sector (Source: gezondheidbelgie.be). At the same time, there is a growing awareness that sustainability is not only necessary for the environment, but also essential for the future viability of healthcare itself.

Why sustainability in healthcare is crucial

Sustainable healthcare means more than just solar panels on the roof or waste separation. It is about an integrated approach that protects the health of people and the planet.

Both in Belgium and the Netherlands, sustainability in the healthcare sector is being tackled through national Green Deals.

In Flanders, the Green Deal Sustainable Healthcare was launched in 2023 and focuses on four themes:

  • Nature & health
  • Climate & infrastructure
  • Materials & waste
  • Medicines in water

In the Netherlands, the Green Deal Sustainable Care 3.0 applies, with the following objectives:

  • 55% CO₂ reduction by 2030
  • 50% reduction in primary raw material use
  • Climate-neutral healthcare by 2050
  • Reduction of environmental impact from medication
  • Greater focus on health and prevention

These ambitions require structural changes in vision, organisation, processes and behaviour.

Sustainability as part of quality standards

It is not only policymakers and healthcare organisations that recognise the importance of sustainability. International standards and accreditation frameworks such as JCI (Joint Commission International) and ISO standards for the healthcare sector are also increasingly including sustainability explicitly in their criteria. Sustainable policy and environmentally conscious behaviour are thus becoming an integral part of quality management and external assessment. Organisations that proactively work on sustainability not only improve their impact on people and the environment, but also strengthen their compliance and quality position.

From vision to anchoring: how support makes the difference

Although many healthcare organisations have incorporated sustainability into their strategic plans, implementation is often delayed due to a lack of structure, knowledge, support or resources. That is why targeted support is crucial.

Hict and Kerteza, both part of Vixor.health, offer concrete support in implementing sustainability with their integrated approach. This service consists of four phases:

4 fasen 830 470

Kerteza 4-Phase Model®

1. Vision development and research

  • Determine the ambition
  • Sustainability scan
  • Kick-off with participants

2. Analysis and advice

  • Gap-analysis of the current situation
  • Concrete advice on a strategic and practical level

3. Implementation and guarantee sustainability

  • Setup project initiation plan
  • Supporting the execution and securing it in policy and practice

4. Evaluatie en doorontwikkeling

  • Intermediate and final evaluations
  • Further optimisation

Sustainable care in practice: examples

Examples of successful sustainable applications include:

  • Waste reduction through reduced use of disposable materials
  • Use of green energy in healthcare buildings
  • Digital healthcare, such as teleconsultation, to limit travel
  • Sustainable medicine production
  • Prevention and lifestyle promotion to reduce the demand for care

These applications not only have ecological benefits, but also save costs and improve the quality of care.

What Hict and Kerteza offer

  • Sustainability scan as a starting point to gain insight into the current situation and perform a substantiated gap analysis between current and desired sustainability performance;
  • Consultancy processes and strategy development;
  • Workshops and training courses to increase support and awareness;
  • Guidance for implementation projects;
  • Embedding sustainability in quality and risk management.

The approach is based on the Hict SDG framework and the Kerteza 4-Phase Model®, with a focus on structure, culture, leadership and processes. By linking the Quintuple Aim to the Sustainable Development Goals (SDGs), five central focus areas emerge within the Healthcare-SDG Framework:

  • Added value for personnel
  • Improving the service and process design
  • Reducing energy output
  • Reducing waste
  • Increasing biodiversity
