Hiring Guide: Sustainability & ESG Strategy

Sustainability and ESG strategy helps businesses assess environmental, social, and governance priorities, identify material risks and opportunities, and turn them into measurable business actions. Freelance sustainability consultants support ESG assessments, materiality, climate and carbon planning, sustainability policies, reporting readiness, target setting, and implementation roadmaps.

The right scope depends on the organisation’s current position. A business starting its first sustainability programme may need a baseline assessment and priority roadmap, while an established company may need stronger ESG governance, reporting preparation, carbon reduction planning, or measurable sustainability targets.

What do sustainability and ESG consultants do?

Sustainability and ESG consultants help businesses understand their current performance, identify priority issues, and build a practical plan for improving environmental, social, and governance outcomes. Their work combines business strategy, data, risk assessment, stakeholder priorities, policies, targets, and implementation planning.

ESG baseline assessment: Review current policies, sustainability data, commitments, business practices, risks, and gaps.
Sustainability strategy: Define priorities, goals, responsibilities, timelines, KPIs, and practical actions linked to business objectives.
Materiality assessment: Identify the environmental, social, and governance issues most relevant to the organisation and its stakeholders.
Carbon and climate planning: Review emissions information, reduction opportunities, climate risks, and actions supporting carbon or net-zero targets.
ESG reporting readiness: Organise data, evidence, policies, responsibilities, and processes needed for sustainability reporting.
Policy and implementation planning: Develop sustainability policies, governance processes, accountability, progress tracking, and implementation roadmaps.

A useful sustainability strategy should make it clear what needs to change, which actions take priority, who is responsible, how progress will be measured, and what evidence supports the recommendations.

When should you hire sustainability and ESG consultants?

Businesses hire sustainability consultants when they need specialist knowledge to assess their current position, develop an ESG strategy, organise sustainability data, prepare for reporting, or turn broad commitments into measurable actions.

Typical projects include:

creating a first sustainability or ESG strategy
reviewing an existing sustainability programme
completing a materiality assessment
developing ESG goals and KPIs
preparing a sustainability roadmap
improving ESG policies and governance
planning carbon reduction initiatives
assessing environmental or climate risks
organising sustainability reporting data
preparing for customer, investor, or stakeholder ESG requirements
benchmarking sustainability performance
developing implementation plans

Projects involving competitor sustainability performance, industry positioning, or peer benchmarking may also require Market & Competitor Research alongside the ESG strategy.

How to hire freelance sustainability and ESG consultants on Osdire

Osdire gives buyers two ways to hire sustainability and ESG consultants. Choose the route based on whether you want to browse specialist profiles directly or receive proposals for a defined ESG project.

Option 1: Browse freelancer profiles

Step 1: Define the sustainability service you need: Start with the outcome. Decide whether the project requires an ESG assessment, sustainability strategy, materiality assessment, carbon plan, reporting support, policy development, or implementation roadmap.
Step 2: Browse relevant freelancer profiles: Use Hire Freelancers to compare sustainability and ESG specialists by relevant experience, industry background, previous projects, frameworks, portfolio evidence, rates, reviews, and availability.
Step 3: Discuss the project and hire: Share your current sustainability position, available data, goals, required deliverables, budget, and deadline. Confirm the project scope, reporting requirements, meetings, revisions, and implementation support before hiring.

Option 2: Post a project and hire

Step 1: Prepare your ESG project brief: Explain your company, industry, sustainability goals, current policies or data, main challenges, required deliverables, budget, and timeline.
Step 2: Post your project on Osdire.: Publish the project so relevant sustainability and ESG freelancers can review your requirements and submit proposals based on the scope.
Step 3: Compare proposals and hire: Compare each proposal by relevant experience, methodology, reporting knowledge, required data, deliverables, timeline, and price. Choose the consultant whose approach best matches the business objective.

If this is your first time working with independent specialists, Osdire’s freelancer hiring guide explains how to compare profiles, project scope, milestones, and delivery expectations before starting.

How much does it cost to hire freelance sustainability and ESG consultants on Osdire?

The cost of hiring sustainability and ESG consultants depends on the type of work required. A focused ESG review requires less research and specialist time than a full sustainability strategy, materiality assessment, carbon programme, or reporting-readiness project. Company size, industry complexity, available data, business locations, stakeholder involvement, reporting requirements, and final deliverables also affect the budget. Typical budgeting ranges include:

Sustainability or ESG consultation: $75 to $250
ESG baseline or gap assessment: $200 to $750
Materiality assessment or ESG roadmap: $500 to $1,500
Sustainability strategy development: $750 to $2,500
Reporting readiness or complex ESG programme: $1,500 to $5,000+
Specialist sustainability consulting: typically $40 to $150+ per hour

Projects involving stakeholder interviews, emissions data, several business locations, specialist reporting requirements, detailed policies, workshops, or implementation planning usually require a larger budget.

Before comparing prices, check what the scope includes. Research, data review, materiality work, carbon analysis, policy development, reporting support, revisions, workshops, and implementation guidance significantly affect the value and depth of the final deliverable.

What should you check before hiring sustainability and ESG consultants?

The right consultant should match the sustainability problem your business needs to solve. Review relevant project experience, industry knowledge, methodology, reporting expertise, data skills, and evidence that previous work resulted in practical actions rather than generic ESG recommendations. Check:

experience with similar sustainability projects
knowledge of your industry
ESG strategy experience
materiality assessment experience
carbon or climate expertise where required
reporting and data knowledge
research methodology
quality of previous deliverables
stakeholder engagement experience
KPI and target-setting approach
implementation experience
relevant sustainability frameworks
timeline and availability
revisions and ongoing support

Framework knowledge should match the project rather than become a checklist. Depending on the business and reporting requirements, relevant experience may include GRI, CDP, SBTi, EcoVadis, CSRD, carbon accounting, climate reporting, or other recognised sustainability standards.

Local knowledge also matters when sustainability requirements, market expectations, or business regulations vary by location. For strategy projects requiring additional UK business context, buyers can also compare freelance business consultants in Aberdeen.

What should you include in a sustainability and ESG project brief?

A clear project brief helps the consultant understand the organisation’s current position, the reason for the project, and the level of sustainability support required before proposing a methodology.

Include:

company background
industry
company size
operating locations
current sustainability activities
existing ESG policies
available sustainability or emissions data
current targets and commitments
main sustainability challenges
relevant stakeholders
reporting requirements
frameworks already used
required deliverables
implementation support required
budget
deadline

Most importantly, explain why the work is being commissioned. Preparing an ESG strategy for internal improvement requires a different approach from responding to investor requests, customer procurement requirements, reporting obligations, or a carbon reduction target.

FAQ

What is the difference between sustainability and ESG?

Sustainability is the broader approach to managing environmental, social, and long-term business impacts. ESG provides a structured way to assess environmental, social, and governance factors that affect business performance, risk, reporting, and stakeholder decisions.

What should an ESG strategy include?

An ESG strategy should define material priorities, current performance, goals, responsibilities, measurable KPIs, policies, data requirements, implementation actions, timelines, and a process for reviewing progress.

Do sustainability consultants help with ESG reporting?

Yes, where reporting support forms part of their expertise. They support data organisation, reporting gap assessments, policy development, evidence preparation, requirement mapping, and reporting readiness. Confirm the relevant framework and final deliverables before hiring.

How long does a sustainability or ESG strategy project take?

A focused assessment may take several days, while a complete sustainability strategy usually takes several weeks. Projects involving stakeholder engagement, multiple business locations, carbon data, or complex reporting requirements require longer timelines.
