Job description

Greenheart is a certified B Corp sustainability advisory practice with a strong market position, an exceptional client base and a fully funded three-year growth plan. They're now looking for a Senior Consultant to join at a genuinely pivotal moment - someone whose technical depth and commercial instincts will help shape a growing environmental practice, not just execute within it.

Location

UK-based, hybrid with monthly office time and quarterly residential gatherings.

Salary

£43,000 to £53,000 depending on experience. Contract type: permanent, full-time.

What you'll be doing

• Lead climate and environmental work for a portfolio of mid-sized clients - GHG inventories (Scopes 1-3), science-based targets, climate transition plans, and nature-related assessments aligned to TNFD and SBTN.
• Act as senior counsel to client sustainability leads and exec teams, translating complex technical standards into clear decisions leaders can actually act on.
• Advise on environmental management, double materiality, and reporting frameworks including CSRD, ISSB and B Corp Environmental requirements.
• Own the commercial performance of your client accounts - spotting where clients need more support and leading those conversations with confidence.
• Coach the wider team's environmental technical depth, building capability rather than dependency as the practice grows.

What you need to bring

• Demonstrable depth as a climate and environmental practitioner - the kind built through complex, real-world work, whether gained consulting to multiple clients or leading it in-house.
• Technical specialism in at least three of: GHG accounting, science-based targets and transition planning, Environmental Impact Assessments, TNFD/LEAP nature-related assessments, B Corp Environmental requirements, or Environmental Management Systems.
• A credible, commercially fluent presence with senior leaders - able to confidently represent technical standards while making sustainability legible to decision-makers.
• Confidence managing account relationships, project budgets and scope conversations - without it ever feeling like a sell.

Why you'll love this job

• Genuine influence over the direction of a growing environmental practice - with clear scope to move into practice leadership as a junior team grows around you.
• A funded growth plan with clear milestones, already backed by strong trading performance, and a brand that is genuinely well-regarded in the sustainability consulting space.
• A values-aligned workplace that lives its B Corp principles - where diversity is seen as a source of resilience, not a compliance checkbox.
