Sustainability & ESG Jobs in Renewable Energy

Sustainability and ESG professionals run the reporting, strategy, and assurance work that turns a company's environmental and social performance into audited disclosure: double materiality assessments, ESRS-aligned reports, science-based targets, and supplier certification checks. The role is the disclosure and the strategy behind it, not the employer's mission statement. That distinction matters in renewable energy more than anywhere, because everyone on the payroll can claim to work on decarbonisation and only a handful of people are accountable for proving any of it to an auditor. Workers in LinkedIn's green talent pool are hired at a 46.6% higher rate than the global workforce, and the gap keeps widening: green hiring grew 7.7% a year between 2021 and 2025 while the share of workers who actually hold green skills grew 4.3%.

CSRD after Omnibus I

The rule that created most of these jobs has just been cut back. The EU's Omnibus I directive, adopted on 24 February 2026 and in force since 18 March, raised the CSRD threshold to companies with more than 1,000 employees and €450 million in net turnover, which takes an estimated 80% of previously in-scope firms out of the regime. Reporting now starts with financial years beginning 1 January 2027, and the first reports land in 2028.

For anyone job hunting, the consequence is concrete. The wave of junior reporting posts at mid-sized developers and suppliers has thinned, and what remains sits with the large utilities and manufacturers that are still in scope, with the consultancies they retain, and in the voluntary value-chain disclosures that smaller suppliers still prepare for in-scope customers. Fewer roles, but deeper ones, and they expect you to have run an assurance cycle rather than populated a template.

Who hires

Cundall, a multidisciplinary engineering consultancy of 501 to 1,000 staff, has advertised more sustainability posts on Rejobs than any other employer over the past year, with Sustainability Consultant and Sustainability Specialist the two recurring titles. Consultancy is where most people enter: you work across a dozen clients and see more reporting cycles in two years than an in-house team sees in five.

Certification and scheme bodies form a separate branch. ISCC, which certifies biofuel, biomethane, and recycled-carbon feedstock chains against the criteria EU fuel obligations refer to, hires auditors and scheme managers rather than corporate reporters, and the work is closer to supply chain forensics than to strategy. Retail suppliers including Octopus Energy and OVO Energy staff sustainability teams to handle own-operations reporting and to defend customer-facing green tariff claims, an area regulators have grown noticeably less patient with. Scottish Power, Wärtsilä, and the energy services firm CLEAResult recruit into the same function on the utility and programme-delivery side.

London carries the largest concentration of postings, ahead of Berlin, Hamburg, Glasgow, Amsterdam, Bristol, and Madrid.

Adjacent specialisms

A sustainability manager commissions technical studies rather than producing them, and knowing where the handover sits saves applying to the wrong job. Product footprints, cradle-to-gate studies, and Scope 3 calculation methods belong to carbon accounting and life cycle assessment. Consenting studies for a specific wind farm or solar site sit with environmental impact assessment, and the habitat surveys and net-gain plans inside them with ecology and biodiversity. Community benefit agreements and local consultation are handled by community and stakeholder engagement teams.

What employers pay for

The premium has moved from breadth to auditability. Employers now screen for people who can build a data trail that survives limited assurance: ESRS datapoint mapping, EU Taxonomy alignment calculations, control design over non-financial data, and enough familiarity with a reporting system such as SAP or Workiva to discuss lineage rather than spreadsheets. Sector knowledge compounds that. Someone who understands why a grid connection date moves, or how a PPA is structured, writes a transition plan a utility board will sign, and that is the part of the job that will not be automated.
