Definitions of the ESG, climate, supply chain and reporting terms that matter when buying, financing or reporting on solar equipment. Each entry states what the term means, then how it applies at LONGi, with links to the evidence.
Also known as: Environmental, social and governance
ESG stands for environmental, social and governance. It is a framework for assessing how a company manages its environmental impact, its relationships with workers, communities and suppliers, and the way it is run and controlled. Investors, lenders and buyers use ESG data to judge risk and long-term resilience.
At LONGi. LONGi reports its ESG performance annually in a Sustainability Report that covers the whole group.
Sustainability means meeting present needs without reducing the ability of future generations to meet theirs. In business it covers resource use, emissions, labour practices and long-term financial viability, and it is reported through frameworks such as GRI and the ISSB standards.
Double materiality is a reporting principle under which a company assesses both how sustainability issues affect its own finances (financial materiality) and how the company's activities affect people and the environment (impact materiality). A topic is reportable if it is material from either perspective. It is the basis of the EU's CSRD.
At LONGi. LONGi's 2024 double-materiality analysis prioritised climate change response, product quality and sustainable supply chain development.
A materiality assessment is a structured process for identifying which sustainability topics matter most to a company and its stakeholders, usually by surveying stakeholders and scoring each topic for impact and financial relevance. The result decides what a company prioritises and reports.
Stakeholder engagement is the practice of consulting the people and groups affected by or affecting a company, such as employees, customers, suppliers, investors, regulators and communities, and using their input in strategy and reporting. It underpins materiality assessments and grievance processes.
Greenwashing is the practice of making environmental claims that are misleading, unsubstantiated or exaggerated. Regulators in the EU and elsewhere increasingly require environmental claims to be specific, evidenced and independently verifiable, for example by citing the figure, the standard and the year.
At LONGi. LONGi's compliance guidance says a defensible environmental claim cites the figure, the standard and the year, and that factory results and product claims are kept separate.
An ESG rating is a score or grade from an independent provider that assesses a company's exposure to, and management of, environmental, social and governance risks. Common providers include EcoVadis, MSCI, S&P Global, CDP and FTSE Russell. Methodologies differ, so ratings from different providers are not directly comparable.
At LONGi. LONGi is assessed by EcoVadis, MSCI, S&P Global, CDP and FTSE Russell.
A sustainability report is a periodic publication in which a company discloses its environmental, social and governance performance, targets and management approach. Reports typically follow a standard such as the GRI Standards and may be independently assured.
At LONGi. LONGi has published a sustainability report annually since 2018. The 2024 report follows the GRI Standards and references IFRS S1 and S2.
Third-party assurance is an independent verification of reported sustainability data by an external body, such as an accredited auditor. It raises confidence in the figures. Limited assurance gives moderate confidence; reasonable assurance gives a higher level comparable to a financial audit.
At LONGi. LONGi's Sustainability Report carries an independent assurance statement, and its GHG inventory has been third-party verified.
A climate action white paper is a company publication that sets out its climate targets, the actions taken, its emissions accounting method and its climate risks and opportunities. It complements the annual sustainability report with a deeper climate focus.
At LONGi. LONGi published its 2024–2025 Climate Action White Paper in November 2025 and outlined a full value-chain net-zero path.
Also known as: Corporate Sustainability Reporting Directive
The Corporate Sustainability Reporting Directive (CSRD) is an EU law requiring large and listed companies to publish audited sustainability information using the European Sustainability Reporting Standards (ESRS). It applies a double-materiality approach and also reaches many non-EU companies with significant EU activity.
At LONGi. LONGi's Sustainability Report is prepared with reference to the GRI Standards and supplies reusable data tables that EU buyers can use in their own CSRD disclosures.
Also known as: European Sustainability Reporting Standards
The European Sustainability Reporting Standards (ESRS) are the detailed reporting standards that companies use to comply with the CSRD. They cover climate, pollution, water, biodiversity, circular economy, own workforce, workers in the value chain, affected communities, consumers and business conduct.
Also known as: Corporate Sustainability Due Diligence Directive
The Corporate Sustainability Due Diligence Directive (CSDDD) is an EU law that requires in-scope companies to identify, prevent and remedy adverse human-rights and environmental impacts in their own operations and value chains. It makes supply chain due diligence a legal duty rather than a voluntary practice.
At LONGi. LONGi says it supports downstream compliance by providing supply chain transparency data to customers.
Also known as: German Supply Chain Due Diligence Act, Lieferkettensorgfaltspflichtengesetz
The LkSG, the German Supply Chain Due Diligence Act (Lieferkettensorgfaltspflichtengesetz), requires companies operating in Germany above a size threshold to carry out human-rights and environmental due diligence across their supply chains, including risk analysis, preventive measures, a complaints procedure and annual reporting.
At LONGi. LONGi states that its due diligence framework is aligned with the requirements of the LkSG.
The EU Forced Labour Regulation prohibits placing on, or exporting from, the EU market any product made with forced labour. Authorities can investigate products and supply chains and order withdrawal, which makes upstream traceability evidence important for importers of goods such as solar modules.
At LONGi. LONGi reports that its 2024 on-site audits of silicon suppliers identified no forced or child labour.
Also known as: Carbon Border Adjustment Mechanism
The Carbon Border Adjustment Mechanism (CBAM) is an EU measure that puts a carbon price on certain imported goods so that they bear a cost comparable to EU-produced goods under the EU Emissions Trading System. It currently covers sectors such as steel, aluminium, cement and fertilisers, and is expected to widen over time.
At LONGi. LONGi says customers importing its products into the EU can request product-level emissions documentation.
Also known as: Global Reporting Initiative Standards
The GRI Standards are a widely used global framework for sustainability reporting. They let organisations report their impacts on the economy, environment and people in a consistent, comparable way, using universal, sector and topic standards.
At LONGi. LONGi's Sustainability Report is prepared in accordance with the GRI Standards.
Also known as: ISSB standards, IFRS Sustainability Disclosure Standards
IFRS S1 and IFRS S2 are the global baseline sustainability disclosure standards issued by the ISSB. S1 sets general requirements for sustainability-related financial disclosures; S2 covers climate-related disclosures and builds on the TCFD recommendations.
At LONGi. LONGi's 2024 Sustainability Report references IFRS S1 and S2.
Also known as: Task Force on Climate-related Financial Disclosures
The Task Force on Climate-related Financial Disclosures (TCFD) set recommendations for disclosing climate risks and opportunities under four pillars: governance, strategy, risk management, and metrics and targets. Its recommendations are now built into IFRS S2.
At LONGi. Following the TCFD framework, LONGi identified 16 transition risks, 65 physical risks and 15 climate-related opportunities, published in its 2023 Climate Action White Paper.
Also known as: Taskforce on Nature-related Financial Disclosures
The Taskforce on Nature-related Financial Disclosures (TNFD) provides a framework for organisations to assess and disclose nature-related dependencies, impacts, risks and opportunities. It extends the TCFD model from climate to biodiversity and ecosystems.
At LONGi. In November 2025 LONGi expanded its ESG disclosure with a first nature-related risk assessment under TNFD.
The Modern Slavery Act 2018 (Australia) requires large entities operating in Australia to publish an annual statement describing the risks of modern slavery in their operations and supply chains and the actions taken to address them. The UK has a similar Modern Slavery Act 2015.
At LONGi. LONGi Solar Australia publishes an annual Modern Slavery Statement under the Australian Act.
Also known as: Loi de vigilance, vigilance plan
The French Duty of Vigilance law requires large French companies to publish and implement a vigilance plan that identifies and prevents serious human-rights and environmental risks arising from their own activities and those of subsidiaries, subcontractors and suppliers.
The EU Taxonomy is a classification system that defines which economic activities count as environmentally sustainable, based on technical criteria for contributing to goals such as climate mitigation while doing no significant harm to others. Manufacturing and installing solar technology are activities covered by it.
Also known as: GHG emissions, CO2e, carbon dioxide equivalent
Greenhouse gas (GHG) emissions are releases of gases, mainly carbon dioxide, methane and nitrous oxide, that trap heat in the atmosphere. Companies measure them in tonnes of CO2-equivalent (tCO2e) and report them by scope under the GHG Protocol.
At LONGi. LONGi's emissions inventory covers Scope 1, 2 and 3 and has been third-party verified.
Scope 1 emissions are direct greenhouse gas emissions from sources a company owns or controls, such as fuel burned in boilers, furnaces and company vehicles, and process emissions from production.
Scope 2 emissions are indirect greenhouse gas emissions from the generation of purchased electricity, steam, heating or cooling that a company consumes. They can be reported using a location-based or a market-based method, the latter reflecting renewable electricity purchases.
At LONGi. LONGi reports that 47.5% of the electricity it consumed in 2024 was renewable, with RE100 targets of 70% by 2027 and 100% by 2028.
Scope 3 emissions are all other indirect greenhouse gas emissions in a company's value chain, both upstream (purchased materials, transport) and downstream (use and end-of-life of products). They are usually the largest part of a footprint and the hardest to measure.
At LONGi. LONGi works to reduce Scope 3 by asking key Tier-1 suppliers to set carbon-reduction targets and obtain ISO 14001 certification.
A carbon footprint is the total greenhouse gas emissions caused by an organisation, product, service or activity, expressed in carbon dioxide equivalent. For a solar module it is usually reported per module, per watt-peak or per kilowatt-hour generated.
Also known as: PCF, product carbon footprint declaration
A product carbon footprint (PCF) is the greenhouse gas emissions associated with a product over a defined part of its life cycle, calculated under a method such as ISO 14067. A cradle-to-gate PCF covers raw materials through to the factory gate.
At LONGi. LONGi reports 53 carbon footprint certifications for wafers, modules and hydrogen products in 2024, across French, Korean and international EPD schemes. For a 665 Wp back contact module, its EPD gives a product-stage total of 214 kg CO2e.
ISO 14067 is the international standard for quantifying and reporting the carbon footprint of a product. It specifies how to set boundaries, collect data and calculate greenhouse gas emissions, enabling consistent product carbon footprints.
At LONGi. LONGi holds an ISO 14067 certificate and Bureau Veritas product carbon footprint declarations for its Hi-MO series, covering raw materials to factory gate.
Also known as: LCA, life cycle assessment, ISO 14040, ISO 14044
A lifecycle assessment (LCA) is a method for quantifying the environmental impacts of a product across its life, from raw material extraction through manufacturing, transport and use to end-of-life. ISO 14040 and ISO 14044 set the principles and requirements.
At LONGi. LONGi conducts life cycle assessments of its products in line with ISO 14040 and ISO 14044.
Also known as: EPD
An environmental product declaration (EPD) is a third-party verified document that reports a product's life-cycle environmental impacts using a standard method. It is based on a lifecycle assessment and is used in procurement to compare products on the same rules.
At LONGi. LONGi reports 4 module EPDs (Italian, Norwegian and International EPD System schemes) and a UL EPD.
Also known as: Evaluation Carbone Simplifiée
The ECS (Evaluation Carbone Simplifiée) is France's simplified carbon-footprint method for photovoltaic modules, used in French energy-regulator (CRE) tenders. It is expressed in kg CO2e per kWp and is issued by an accredited body.
At LONGi. LONGi holds 24 module and 13 wafer ECS certificates issued by Certisolis.
Embodied carbon is the greenhouse gas emissions released in making a product, including raw material extraction, manufacturing and transport, before it is used. For solar modules it is the upfront emissions that are repaid through the electricity the module generates over its life.
At LONGi. In LONGi's EPD for a 665 Wp back contact module, cells account for 59.3% of the product-stage footprint, glass for 15.8% and the aluminium frame for 14.6%.
Carbon neutrality means balancing the greenhouse gas emissions an entity causes with an equivalent amount removed or offset, so that net emissions are zero. Claims should state their scope and method, because offsetting is not the same as eliminating emissions.
At LONGi. LONGi makes no carbon-neutrality claim for its modules. The Jiaxing factory is certified as a zero-carbon factory under ISO 14068, relying on on-site solar, renewable electricity certificates and verified carbon credits.
Also known as: Net-zero emissions
Net zero means cutting greenhouse gas emissions as close to zero as possible, in line with climate science, and neutralising only the small residual with permanent carbon removals. It differs from carbon neutrality, which can rely on offsets without deep cuts.
At LONGi. LONGi's 2024–2025 Climate Action White Paper outlines a full value-chain net-zero path.
Also known as: SBTi, science-based targets
The Science Based Targets initiative (SBTi) validates corporate emissions-reduction targets against climate science. Targets are 'science-based' if they are consistent with limiting warming to 1.5°C above pre-industrial levels, as in the Paris Agreement.
At LONGi. LONGi reports emissions-reduction targets under the SBTi, aligned with 1.5°C, covering Scope 1 and 2 and Scope 3 purchased goods, set for 2030 against a 2020 base.
Also known as: 1.5°C goal

At LONGi. LONGi has joined EP100.
Also known as: REC, guarantee of origin, I-REC
A renewable energy certificate (REC) is a tradable instrument representing one megawatt-hour of electricity generated from a renewable source. Buying RECs lets a company claim the renewable attributes of that generation in market-based Scope 2 reporting.
At LONGi. LONGi's zero-carbon factory status relies in part on renewable electricity certificates.
Also known as: Carbon credit
A carbon offset, or carbon credit, represents one tonne of CO2e avoided or removed elsewhere and is bought to compensate for a company's own emissions. Offsets do not reduce a company's own footprint, so credible climate claims separate real reductions from offsetting.
At LONGi. LONGi's Jiaxing zero-carbon factory status uses verified carbon credits for the small remainder of emissions.
A zero-carbon factory is a production site certified to have balanced its operational greenhouse gas emissions, for example under ISO 14068, usually through energy efficiency, renewable electricity and verified credits for the remainder. The status applies to the site, not to the products it makes.
At LONGi. LONGi's Jiaxing base is certified as a zero-carbon factory under ISO 14068 and the status does not extend to modules.
A Lighthouse Factory is a manufacturing site recognised by the World Economic Forum's Global Lighthouse Network for applying advanced digital technologies such as AI and automation at scale to improve productivity and sustainability.
At LONGi. LONGi's Jiaxing factory was recognised as a WEF Lighthouse Factory and later certified as a zero-carbon factory.
Energy payback time is how long a solar system must operate to generate the energy used to produce it. For modern crystalline silicon modules it is typically measured in months to a few years, much shorter than a module's operating life.
Supply chain traceability is the ability to track a product and its materials back through each stage of production to their origin, supported by records and audits. It lets buyers verify where materials came from and respond to regulations on forced labour and due diligence.
At LONGi. LONGi's traceability covers the silicon chain from polysilicon to module, with the system built on ISO 9001:2015 and SEIA traceability standards and audited by bodies including STS, PI Berlin, SGS and TÜV Rheinland.

At LONGi. LONGi states that suppliers across all tiers sign its Supplier Code of Conduct before receiving a purchase order. It covers business ethics, labour and human rights, health and safety, environment and traceability.
A supplier audit is an inspection of a supplier's facilities, records and practices, on site or remote, to check compliance with a buyer's standards and the law. Findings lead to corrective actions, and serious breaches can end the relationship.
At LONGi. In 2024 LONGi carried out 71 on-site audits across 48 key suppliers, covering 73% of bill-of-materials procurement value, using 84 audit criteria.
Also known as: HRDD
Human rights due diligence is an ongoing process through which a company identifies, prevents, mitigates and accounts for adverse impacts on people across its operations and value chain. It is set out in the UN Guiding Principles and OECD guidance.
At LONGi. LONGi trains suppliers on human-rights due diligence based on the UN Guiding Principles and reports 100% supplier ESG due diligence coverage.
Also known as: UNGPs
The UN Guiding Principles on Business and Human Rights (UNGPs) are the global standard for corporate human-rights responsibility. They rest on three pillars: the State duty to protect, the corporate responsibility to respect, and access to remedy.
Forced labour is work that a person does involuntarily and under threat of penalty, including debt bondage and coercion. International and national laws prohibit it, and companies are expected to identify and remove it from their supply chains.
At LONGi. Forced labour is a red-line issue under LONGi's Supplier Code of Conduct. LONGi reports that its 2024 audits found no forced or child labour at silicon suppliers.
Modern slavery is an umbrella term for exploitation including forced labour, debt bondage, servitude, human trafficking, deceptive recruitment and the worst forms of child labour. Several countries require companies to report on modern-slavery risks.
At LONGi. LONGi's statement adopts the definition used in Australia's Modern Slavery Act.
