Our Story

Founded in 2014, sequoia-port emerged from a straightforward observation: many organisations wanted to reduce their environmental impact but lacked access to practical, affordable guidance. Too often, sustainability consulting felt disconnected from operational realities.

We built our practice around a different model. Rather than delivering lengthy reports that gather dust, we focus on implementable strategies that align with business objectives. Our clients achieve measurable environmental improvements while often reducing operational costs.

Today, we work with manufacturers, property developers, local authorities, and service businesses across Yorkshire and beyond. Each engagement draws on our accumulated expertise while remaining tailored to the specific context and constraints our clients face.
