Navigating sustainability with flexibility: interim and part-time experts at your service

Sustainability is becoming a core expectation from stakeholders, but for many organizations, building a full-time team isn’t always the right move – especially when regulations are still evolving and resources are tight. Sustainability topics often range a broad field of expertise, and recruitment can be challenging.

That’s where interim and part-time sustainability experts come in – offering tailored, agile support exactly when and where it’s needed.

Why choose interim or part-time sustainability support?

There are plenty of situations where bringing in an expert on a flexible basis makes sense:

  • Regulatory uncertainty: when rules and regulation are still taking shape, it’s hard to justify big investments but clients, investors, and financiers still expect action.
  • Flying solo: many sustainability leads in organizations operate alone or have several other hats. A part-time expert can be a valuable sparring partner, complement the team temporarily, or bring in specific know-how.
  • Recruitment gaps: interim experts can step in during hiring freezes, transitions, or parental leaves.
  • Special needs: whether it’s the EU taxonomy, Science-Based Targets (SBTs) setting, CSRD reporting transition, or human rights due diligence, niche experts can be brought in for targeted support.

What makes this model work?

These services are designed to be highly customizable to customer needs:

  • Pay only for what you need: whether it’s a few hours, several months, or a project, the setup adjusts to your timeline and budget. You can ramp up during reporting season and scale down during quieter periods.
  • Just the right expert for the job: from sustainability reporting to strategy, communications to project management, you’ll be matched with the person or team who fits your needs. The expert can further tap into the entire team of sustainability specialists at Miltton.
  • No rigid job descriptions: if your project is hard to grasp, an expert can come in to scope the work and help you get started. They also adapt as things evolve and are ready to jump in and handle urgent tasks, too.

In short, interim and part-time sustainability experts offer a smart, practical solution for companies navigating complexity, change, or growth. Whether you’re laying the groundwork for future compliance or tackling urgent sustainability goals, flexible expertise can make all the difference.
