Speeki Guardian® is our solution for the assurance of all sustainability reports and statements

Assurance of your sustainability report or statements is expected.

Mandatory assurance of sustainability reports is essential to establish the credibility, comparability, and reliability that stakeholders require for decision-making, mirroring the fundamental principle that underpins financial reporting regulation.

Without mandatory assurance, sustainability disclosures remain unverified management assertions susceptible to greenwashing, selective disclosure, and optimistic bias—undermining investor confidence, distorting capital allocation, and creating competitive disadvantages for organizations that voluntarily invest in rigorous verification while competitors make unsubstantiated claims without consequence

    Sustainability Report & Regulatory Disclosure Assurance

    Speeki Guardian® provides independent third-party assurance of both voluntary sustainability reports and mandatory regulatory disclosures across all major frameworks and requirements.

    For voluntary reporting, we assure comprehensive sustainability reports prepared under GRI Standards, integrated reports following the International Framework, or voluntary disclosures communicating ESG performance to investors, customers, employees, and stakeholders. For mandatory reporting, we verify compliance with regulations including the EU's Corporate Sustainability Reporting Directive (CSRD) with ESRS standards, SEC climate disclosure requirements, UK sustainability reporting mandates, Singapore's climate requirements, and IFRS ISSB standards adopted across multiple jurisdictions. Our assurance engagements verify the accuracy of sustainability data across environmental, social, and governance metrics; validate completeness against framework or regulatory requirements; assess materiality determination processes including double materiality under CSRD; evaluate stakeholder engagement quality; examine data collection systems, calculation methodologies, and internal controls; and provide independent assurance opinions aligned with ISSA 5000 and AA1000AS v3 that build credibility and satisfy regulatory expectations.

    This assurance is essential as sustainability reporting transitions from voluntary corporate communications to mandatory regulatory requirements with significant penalties for non-compliance, misstatement, or misleading information. Speeki Guardian® reduces regulatory compliance risk, demonstrates good faith efforts to meet disclosure obligations, provides legal defensibility if disclosures face scrutiny or enforcement actions, and positions organizations favorably as assurance requirements evolve from voluntary to mandatory—with the EU's CSRD requiring limited assurance initially and reasonable assurance within several years. Beyond regulatory compliance, assured reports satisfy investor demands for verified ESG information, differentiate organizations through credible commitments, demonstrate leadership, and build trust with customers and communities who increasingly scrutinize sustainability claims. Unlike unassured disclosures that stakeholders may view skeptically, Speeki Guardian® verified reports carry the weight of independent verification, transforming sustainability communications from promotional material into trusted, decision-useful information that supports capital allocation, risk assessment, and stakeholder confidence while protecting against greenwashing allegations and reputational damage.

    Sustainability Statement & Claims Assurance

    Speeki Guardian® provides independent verification of standalone sustainability statements, claims, and commitments published outside comprehensive reports—including website sustainability pages, marketing brochures, product packaging claims, annual report ESG sections, investor presentations, corporate responsibility statements, public commitments and pledges, and other shorter-form communications where sustainability information appears. Our assurance examines specific claims about environmental performance (carbon emissions reductions, renewable energy use, waste diversion, water conservation), social impacts (diversity statistics, living wage commitments, community investment, supply chain practices), governance practices (board diversity, ethics programs, transparency commitments), and product sustainability attributes (recycled content, carbon footprint, circularity, ethical sourcing) to verify that published statements are accurate, substantiated by evidence, not misleading in context, and consistent with underlying data and management systems.

    We assess whether claims are appropriately qualified with boundaries, timeframes, and methodologies; identify overstatements or unsubstantiated assertions that create greenwashing risk; and provide assurance opinions covering specific statements or entire communications that enable confident publication while protecting against regulatory enforcement and reputational damage.

    As regulators worldwide introduce green claims legislation requiring substantiation of environmental marketing claims—organizations face material legal risks from unverified sustainability statements appearing anywhere in public communications. Speeki Guardian® verification of sustainability statements provides the substantiation evidence that satisfies regulatory requirements, protects against enforcement actions and penalties, enables confident marketing of sustainability credentials, and differentiates verified claims from competitors' unsubstantiated assertions that face increasing consumer and regulator skepticism.

    This assurance is particularly critical for consumer-facing organizations where sustainability claims influence purchasing decisions, B2B organizations where procurement processes require verified supplier sustainability credentials, and any organization using sustainability positioning as competitive differentiation.

    Unlike comprehensive report assurance covering hundreds of data points, statement-level assurance focuses verification effort on the specific claims you're actually communicating to markets, providing cost-effective credibility for the sustainability information that stakeholders actually see and rely upon when making decisions about your organization.

    Green Finance & Sustainable Investment Reporting Assurance

    Speeki Guardian® provides independent verification of sustainability reporting associated with green bonds, sustainability-linked loans, sustainability bonds, transition bonds, ESG funds, and other sustainable finance instruments that require ongoing reporting to investors on use of proceeds, achievement of sustainability performance targets, or impact metrics.

    Our assurance engagements verify that proceeds from green or sustainability bonds have been allocated to eligible projects meeting framework definitions (renewable energy, green buildings, clean transportation, etc.); validate achievement of key performance indicators (KPIs) linked to loan pricing or covenant terms in sustainability-linked facilities; assess impact reporting demonstrating environmental or social outcomes from financed projects; and verify compliance with applicable frameworks including ICMA Green Bond Principles, Loan Market Association Green Loan Principles, or Climate Bonds Standard requirements.

    This reporting assurance complements initial framework verification or second-party opinions by providing ongoing, independent confirmation that sustainability-linked financial instruments are delivering promised environmental or social outcomes.

    Investors in sustainable finance instruments increasingly demand assurance of ongoing reporting to protect against greenwashing, ensure accountability for sustainability commitments, and validate that financial benefits tied to sustainability performance are appropriately triggered or withheld based on verified achievement.

    For issuers and borrowers, Speeki Guardian® assurance demonstrates commitment to transparency and accountability, strengthens investor confidence in sustainable finance offerings, enables access to growing pools of ESG-focused capital, and protects reputation if sustainability-linked financial terms face stakeholder scrutiny.

    As sustainable finance markets mature and regulators introduce requirements such as the EU Green Bond Standard mandating external verification, third-party assurance through Speeki Guardian® transitions from competitive differentiator to market expectation—making independent verification of sustainable finance reporting essential infrastructure for organizations accessing sustainability-linked capital markets.

    Carbon Neutrality & Climate Claims Verification

    Speeki Guardian® provides rigorous verification of carbon neutrality claims, net zero commitments, climate positive assertions, and other climate-related marketing and disclosure claims that face increasing regulatory scrutiny under emerging green claims legislation in the EU, UK, California, Australia, and other jurisdictions.

    Our verification examines whether carbon neutrality claims meet recognized standards such as PAS 2060; validates the completeness and accuracy of GHG inventories underlying carbon claims including proper boundary setting and Scope 3 inclusion; assesses the quality and additionality of carbon offsets or credits used to support neutrality claims; evaluates whether reduction targets and timelines align with science-based pathways; and determines whether climate claims in marketing materials, sustainability reports, or product labeling are substantiated, accurate, and not misleading to consumers or investors.

    We provide independent verification that climate claims are backed by robust data, appropriate methodologies, and credible carbon accounting rather than aspirational statements unsupported by evidence.

    As regulators worldwide crack down on greenwashing with significant penalties for unsubstantiated environmental claims—including the EU's Green Claims Directive requiring pre-approval of environmental marketing claims, UK CMA enforcement actions, and US FTC Green Guides—organizations making carbon neutrality or net zero claims face material legal and reputational risks if claims prove exaggerated or misleading.

    Speeki Guardian® verification provides legal defensibility by ensuring climate claims meet substantiation requirements, protects reputation by preventing greenwashing allegations that can devastate brand value, and builds stakeholder confidence that your climate commitments represent genuine action rather than marketing spin.

    For organizations using carbon neutrality or climate leadership as competitive differentiators in sustainability-conscious markets, independent verification through Speeki Guardian® transforms marketing claims from potential liabilities into verified competitive advantages, enabling you to communicate climate action confidently while competitors without credible verification face increasing skepticism and regulatory risk.

  • ESG Rating & Rankings Data Verification

    Speeki Guardian® verifies the underlying data and methodologies you submit to ESG rating agencies, sustainability indices, industry rankings, and award programs—ensuring accuracy, completeness, and consistency of ESG information that influences your organization's ratings, rankings, and market perception.

    Our verification examines data submissions to major rating agencies including MSCI, Sustainalytics, CDP, ISS ESG, and others; validates alignment between submitted data and source documentation including sustainability reports, regulatory filings, and internal management systems; identifies inconsistencies, gaps, or errors that could negatively impact ratings; assesses whether qualitative responses accurately represent policies, practices, and performance; and provides assurance that your ESG data submissions fairly represent your actual sustainability position rather than aspirational or selectively disclosed information. This pre-submission verification helps optimize your ESG ratings by ensuring data quality and completeness while providing defensible documentation if ratings face internal or external challenges.

    ESG ratings significantly influence investment decisions, cost of capital, customer perceptions, employee attraction, and competitive positioning—yet many organizations discover rating downgrades or negative assessments result from incomplete data submissions, misunderstood questions, or inconsistencies between public disclosures and rating agency responses rather than actual performance deficiencies.

    Speeki Guardian® verification provides a quality control layer that prevents rating impacts from data issues, strengthens internal ESG data management capabilities, and demonstrates to rating agencies that your submissions have undergone independent verification increasing confidence in disclosed information.

    For organizations where ESG ratings materially affect access to capital, procurement opportunities, or market reputation, the cost of Speeki Guardian® verification is modest compared to the financial and reputational consequences of rating downgrades resulting from preventable data quality issues—making independent verification of rating submissions a strategic necessity rather than optional assurance.

  • Crisis Response & Disclosure Remediation Assurance

    When your organization faces greenwashing allegations, regulatory investigations, media scrutiny, activist campaigns, or stakeholder challenges questioning the accuracy of sustainability claims or disclosures, Speeki Guardian® provides independent verification of corrected or updated disclosures that rebuilds credibility and demonstrates commitment to transparency and accuracy. Our crisis response assurance engagements conduct thorough investigations of challenged claims or disclosures; identify inaccuracies, overstatements, or misleading elements requiring correction; verify corrected or restated information meets appropriate standards and methodologies; assess remediation of underlying data quality issues or control deficiencies; and provide independent assurance opinions on revised disclosures that stakeholders can rely upon as credible corrections. We deliver rapid-response assurance services when reputational damage requires immediate credible verification, as well as comprehensive remediation programs that address systemic disclosure quality issues preventing future credibility challenges.

    Greenwashing allegations can rapidly escalate into material reputational crises, regulatory enforcement actions, securities litigation, customer boycotts, and investor confidence erosion—requiring organizations to respond with credible evidence of corrective action rather than defensive statements that further damage trust. Speeki Guardian® independent verification of corrected disclosures provides the third-party credibility essential for crisis resolution, demonstrating to regulators that you've taken allegations seriously and implemented appropriate remediation, showing investors that restated information is reliable, and rebuilding stakeholder confidence that your organization is committed to disclosure accuracy rather than defending indefensible claims. For organizations emerging from sustainability-related crises, Speeki Guardian® ongoing assurance establishes monitoring and verification infrastructure that prevents recurrence, satisfies settlements or consent orders requiring independent oversight, and gradually rebuilds the stakeholder trust that represents your most valuable intangible asset following reputational damage from disclosure failures.
