Carbon Consultant in London

Future Plus helps businesses understand, measure and improve their sustainability.

We combine our Future Impact assessment and certification platform with practical consultancy and Plus Carbon carbon accounting tool to turn ambition into measurable progress.

We believe sustainability should be accessible, manageable and useful to the people running a business.

Our clients need to know where they stand, what to prioritise and how to demonstrate progress.

We give them the tools, evidence and support to do that.

Carbon is an important part of this work.

We’re looking for someone to manage our carbon accounting services, build trusted client relationships, and drive the expansion of our carbon practice.

The Role

You’ll take ownership of the technical delivery of Future Plus’ carbon services, and you’ll be responsible for the quality of our outputs and the advice we give clients.

Reporting to the Head of Consultancy, you’ll combine hands‑on delivery with responsibility for developing our methodology, supporting business growth and informing improvements to Plus Carbon.

You’ll manage carbon projects independently, from initial scoping and data collection through to reporting and reduction planning.

Our clients range from SMEs taking their first steps to more complex businesses with multiple sites and international operations.

You’ll need to be confident resolving methodological questions, translating complex findings into practical recommendations and helping clients make informed decisions about reducing emissions.

You’ll also play an active role in growing our carbon offering, leading product demos, developing proposals, shaping solutions around client needs and converting opportunities into sales.

You’ll be comfortable explaining the commercial value of Plus Carbon and our consultancy services, building relationships and winning new business.

We’re a small, growing team, so this role suits someone who enjoys taking ownership, sharing ideas and getting involved across the business, including supporting colleagues on wider consultancy projects when needed.

Key responsibilities

• Carbon measurement and reporting
• Own, maintain, and enhance the Future Plus carbon accounting methodology, ensuring alignment with the GHG Protocol Corporate Standard, Scope 2 Guidance, Scope 3 Value Chain Standard, and incorporating the newly operational Land Sector and Removals Standard.

Work alongside client teams to support the development of solutions to complex data management challenges and gather consistent operational and financial data.

• Calculate organisational Scope 1, 2, and 3 footprints using activity-based, spend-based, and hybrid methods, including dual location- and market-based accounting for electricity, ensuring strict adherence to contractual instrument criteria.

• Prepare clear, executive-ready reports and support clients with regulatory, voluntary, and procurement disclosures, including SECR, public sector carbon reduction plans, and supply chain questionnaires.
• Prepare client inventories, calculation workbooks, and data management plans to withstand independent third‑party audit.
• Develop repeatable methods, calculation templates, and workflows, testing responsible uses of AI to improve efficiency while maintaining strict traceability and accuracy.
• Reduction and transition planning
• Turn carbon footprints into practical, costed reduction plans that reflect each client’s operations, resources and priorities.
• Forecast emissions against business growth, helping clients identify and prioritise reduction projects based on upfront investment, ROI, and carbon impact.
• Support target setting and transition planning, drawing on relevant frameworks such as SBTi and the Transition Plan Taskforce.
• Establish responsibilities, milestones and review processes so clients can track delivery and adjust their plans.
• Evaluate the evidence behind client emissions‑reduction claims to safeguard clients and ensure alignment with emerging green claims guidance.
• Business development and product improvement
• Join sales calls as the carbon specialist, deliver platform demos and help scope and price new projects.
• Identify opportunities to support existing clients further, from ongoing carbon management to wider Future Plus services.
• Represent Future Plus at relevant events and build relationships with prospective clients and partners.
• Deliver workshops, webinars and carbon training, including within cohort programmes.
• Use client feedback and delivery experience to improve our Plus Carbon workflows, templates and guidance, and work with our technology partner to inform platform improvements.
• Bring a carbon and climate perspective to multi‑topic client engagements, helping connect emissions work with clients’ wider sustainability goals.
