Portrait — Mikhail Ostanin
Background

From sustainable management to supporting organisations

After a career in human resources, I chose to specialise in sustainable management at Le Mans University, before joining ESCP Business School for my first professional experience.

These projects allowed me to:

  • follow international accreditations,
  • develop awareness campaigns,
  • contribute to reducing the carbon footprint.

I work as an external consultant to strengthen your ongoing sustainability projects, bringing flexibility, cost control and targeted expertise.

I can also design and implement projects from the ground up, building clear, operational plans tailored to your situation.

Why choose me

Turning ambitions into concrete actions.

The ecological and social transition may seem complex or costly. Yet it becomes accessible when it is structured with method.

I can:

  • Identify your improvement levers
  • Detect your blocking points and propose concrete solutions
  • Structure a clear and realistic roadmap
  • Showcase your commitments to your stakeholders

Each project is adapted to your reality: resources, regulatory constraints, sector context and stakeholder expectations.

Method

Let’s build your CSR projects together

I work hand in hand with my clients.

Each assignment starts with a precise diagnosis to identify your priorities:

  • reducing your carbon footprint
  • anticipating regulatory obligations
  • internal governance and social practices
  • clear and credible communication

Together, we define a pragmatic, realistic and measurable roadmap.

I train and equip your teams so that they become drivers of your transition.
