Making sustainability and responsible business solutions simple and cost-effective

What we do

Aspen Sustainability Consulting & Contracting provides a specialist, cost-effective sustainability management resourcing solution for organisations. Flexible engagement terms are offered on either a self-employed or employed basis.

Aspen reflects the services of Ollie Swan, a Chartered Environmentalist, who has gained 30 years' sectoral experience across higher education, the NHS and local government. His success is in combining sustainability with commercialisation, reputational profile, and performance.

Clarity, insight and leadership is offered on these common support needs - for example, you might:

Require interim support for an unfilled vacancy
Wish to improve your sectoral positioning and reputation
Have a corporate reporting requirement
Need to plan for an audit inspection or have concern your management plan is resource-intensive
Require specialist support with NHS, university, or government supplier questionnaires
Have escalating energy and water costs without a clear management plan

Why choose Aspen?

Access to senior sustainability expertise and insider insight without the commitment of permanent recruitment or cost of larger consultancies' overheads.

The person you speak to is the person who delivers the work. You have direct access to an experienced sustainability consultant from initial discussions through to project completion, providing continuity, accountability and a deeper understanding of your organisation throughout the assignment.

Unique as compared to larger consultancies is our engagement terms; flexible interim, freelance, project-based or employed support. We add specialist capability and extra capacity whenever your organisation needs it—whether to deliver a specific project, cover a skills gap or provide additional resource during periods of change.
