Fluence Energy publishes fourth annual sustainability report

Fluence Energy's FY2025 report sets its first Scope 1 and 2 emissions baseline and claims the top ranking in Corporate Knights' global sustainability index.

Fluence Energy publishes fourth annual sustainability report

Fluence Energy (NASDAQ: FLNC), the Arlington, Virginia-based energy storage and optimisation software vendor, has released its fiscal year 2025 Sustainability Report, covering the twelve months to 30 September 2025. Now in its fourth year, the report is the company's most disclosure-heavy to date, introducing a first-ever baseline for Scope 1 and 2 greenhouse gas emissions and completing a second Task Force on Climate-related Financial Disclosures (TCFD) aligned report.

The document is prepared against a cluster of established ESG frameworks: the Global Reporting Initiative, the Sustainability Accounting Standards Board standards, and TCFD. Fluence also maintains its annual commitment to the United Nations Global Compact and maps its programme to several UN Sustainable Development Goals. Separately, the company received a Commitment Badge in its first EcoVadis assessment, a supplier-ratings platform used by enterprise procurement teams to screen vendors on environmental and social criteria.

What the report covers

The headline metric is the establishment of the Scope 1 and 2 baseline, which gives investors and customers a reference point for tracking operational emissions reduction over future reporting periods. Fluence has not yet published a Scope 3 inventory, which covers supply-chain and downstream emissions. For a company that manufactures and deploys battery energy storage systems at gigawatt scale, Scope 3 is likely to represent the largest share of total lifecycle emissions; its absence from this cycle will be noted by institutional investors applying Science Based Targets initiative criteria.

Corporate Knights named Fluence the most sustainable corporation in the United States and ranked it fourth worldwide in its latest assessment. Corporate Knights screens large-cap companies on revenue intensity metrics across energy, water, waste and carbon, weighting clean-revenue share heavily. Fluence's core business in grid-scale storage and renewable optimisation software means it scores strongly on clean-revenue proportion by construction, which is worth bearing in mind when comparing its ranking to diversified industrials.

Market and regulatory context

Grid-scale battery storage has moved from a niche grid-stabilisation tool to a central component of power-system planning across Europe, North America and parts of Asia-Pacific. Utilities and independent power producers are deploying storage alongside solar and wind to manage intermittency, while data-centre operators are increasingly treating battery arrays as a power-quality and reliability asset. Chief executive Julian Nebreda noted in the report that digital infrastructure for artificial intelligence is creating new demand for energy storage, a dynamic that is accelerating procurement cycles across the sector.

Fluence competes in a market that includes established players such as Tesla Energy, BYD, CATL's stationary storage arm and a range of system integrators. Differentiation is shifting from hardware towards software and services: Fluence's asset optimisation platform is positioned as the higher-margin layer above commodity battery hardware, a model that gives the company structural reasons to invest in ESG credibility, as enterprise and utility buyers apply increasingly rigorous vendor-sustainability criteria in procurement.

On the regulatory side, the EU's Corporate Sustainability Reporting Directive came into force for large companies in 2024 and extends to non-EU companies with significant European revenue from 2028. The SEC's climate-disclosure rules, though subject to ongoing legal challenge in the United States, have moved Scope 1 and 2 reporting from voluntary best practice to near-mandatory for listed companies. Fluence's decision to establish a formal emissions baseline in FY2025 is consistent with that trajectory, even if the timing is partly driven by investor relations rather than a hard compliance deadline.

Fluence said the full report is available to download from its website. The company did not announce new emissions reduction targets or a net-zero commitment date alongside the publication.
