Our approach

Our ESG strategy design and CSRD compliance process

01

Materiality assessment

We identify the ESG issues that are material to your company and its stakeholders, prioritise impacts, and establish the foundation for a coherent strategy.

02

ESG strategy design

We define objectives, key performance indicators, and action plans across the three dimensions -- environmental, social, and governance -- aligned with CSRD and the SDGs.

03

Implementation & governance

We integrate the ESG strategy into business processes, establish the governance structure, and train teams to ensure effective execution.

04

Reporting & verification

We prepare the sustainability report under ESRS/GRI standards, prepare data for external verification, and advise on communication to investors and stakeholders.

The challenge

ESG demands are no longer voluntary. European CSRD regulation, institutional investor requirements, and pressure from clients and talent are forcing companies to demonstrate a genuine commitment to sustainability. Without a structured strategy, the risk of regulatory non-compliance, loss of financing, and reputational damage is growing fast.

Our solution

We design and implement ESG strategies aligned with European regulatory frameworks and international best practices. From materiality assessment to sustainability reporting, we help you integrate ESG into the core of your business and communicate it credibly to all stakeholders.

ESG (Environmental, Social, and Governance) is a framework used by investors, regulators, and companies to measure and manage performance across three non-financial dimensions: environmental impact (including climate change, resource use, and biodiversity), social responsibility (covering employees, supply chain, and communities), and corporate governance (board structure, transparency, and ethical conduct). In the EU, ESG reporting has been made mandatory for large companies through the Corporate Sustainability Reporting Directive (CSRD), which requires disclosure under the European Sustainability Reporting Standards (ESRS) and limited external assurance, with Spain's first large non-listed companies reporting on fiscal year 2025. ESG performance increasingly affects access to financing — EU green loan frameworks (LMA Green Loan Principles) and sustainability-linked instruments link borrowing costs to verified ESG KPIs — and institutional investors apply ESG criteria in allocation decisions through frameworks such as the EU Sustainable Finance Disclosure Regulation (SFDR).

Sustainability has moved from a nice-to-have to a strategic imperative. Our team combines deep regulatory knowledge with practical ESG integration experience to help your company lead in this area credibly and measurably.

Why ESG Demands Are No Longer Voluntary for Spanish Companies

Companies face an ESG challenge on two fronts simultaneously. The regulatory front requires CSRD-compliant reporting under ESRS standards from 2025-2026, with external assurance — a fundamentally different standard from the voluntary ESG reports most companies have published to date. The market front requires credible ESG performance data to satisfy investor due diligence, secure sustainability-linked financing at preferential rates, and retain institutional clients and supply-chain positions that now screen on ESG criteria. Many companies are caught between both pressures without a coherent ESG strategy that addresses both at once. The risk of regulatory non-compliance is real — but the loss of financing access and supply-chain positions for companies that cannot demonstrate ESG credentials is already happening, not theoretical.

Our ESG Strategy Design and CSRD Compliance Process

We begin with the double materiality assessment — identifying which sustainability topics are material both from an impact perspective and from a financial risk and opportunity perspective. This assessment is mandatory under CSRD and forms the foundation for a reporting system that is both compliant and strategically useful. We design the ESRS-aligned reporting framework, establish data collection processes across the value chain, coordinate with external auditors for limited assurance, and develop the underlying ESG strategy — targets, initiatives, governance structures — that gives the report its substance. We integrate ESG analysis with financing strategy, identifying sustainability-linked loan opportunities for companies that meet threshold criteria. Our CSRD reporting specialists handle the technical reporting obligations while the ESG strategy team ensures the underlying performance programme generates the improvements the report must reflect.

Real Results in ESG: Financing Cost Reduction and Investor Access

  • 90+ ESG mandates completed across materiality assessment, strategy design, CSRD reporting, and ESG rating improvement.
  • Sustainability-linked loan arrangements with margin ratchets of 5-25 basis points tied to verified ESG KPIs — an 18% average financing cost reduction for clients accessing these instruments.
  • Double materiality assessment conducted to the standard required by CSRD and external auditors, with documented evidence for every material determination.
  • ESG rating improvement plans for MSCI, Sustainalytics, and CDP: gap analysis, improvement roadmap, and tracking of rating changes.
  • EU Taxonomy alignment calculation integrated with financial data for consistent, auditable disclosure.

The CSRD and ESRS represent the most comprehensive overhaul of non-financial reporting in EU history. Large companies already subject to the NFRD reported from fiscal year 2024; other large companies report from fiscal year 2025; listed SMEs from fiscal year 2026. Reports must be included in the management report, prepared under ESRS, and subject to limited assurance by a qualified auditor. The EU Taxonomy Regulation requires parallel disclosure of turnover, capital expenditure, and operating expenditure aligned with environmentally sustainable activities. For companies preparing for an IPO, ESG readiness directly affects book-building quality and pricing: institutional investors use CSRD data to compare companies with a precision that voluntary reports never permitted. The double materiality process also surfaces operational risks and efficiency opportunities that generate savings independent of any financing or capital markets benefit.

Track record

Real results in ESG: financing cost reduction and investor access

BMC guided us through our first CSRD materiality assessment and helped us design an ESG strategy that is genuinely integrated into our business rather than a compliance exercise. Our financing bank has already recognised the improvement with a reduction in our margin.

FAQ

Frequently asked questions about ESG strategy, CSRD, and sustainable finance

The Corporate Sustainability Reporting Directive (CSRD) is the European regulation requiring companies to report comprehensively on their sustainability impacts. It applies progressively from 2025 to large companies and listed entities, and from 2026 to SMEs listed on regulated markets. The scope will be broadened gradually.
The European Sustainability Reporting Standards (ESRS) are the mandatory ESG reporting standards under CSRD. They cover environmental topics (climate change, biodiversity, pollution, water), social topics (workers, communities, value chain), and governance. Compliance requires double materiality: the company's impact on the world and the world's impact on the company.
Institutional investors and banks incorporate ESG criteria into their investment and lending decisions. A strong ESG profile improves access to green and sustainable finance, reduces the cost of capital, and attracts funds with responsible investment mandates.
Yes, we advise on improving ESG ratings from leading agencies (MSCI, Sustainalytics, CDP). We analyse evaluation criteria, identify gaps, and design improvement plans to optimise your score.
CSR (Corporate Social Responsibility) is largely voluntary and philanthropic. ESG is a quantitative and comparable assessment framework used by investors, banks, and regulators to measure risks and opportunities. ESG is more rigorous, more comparable, and increasingly mandatory.
We work with companies of all sizes. For SMEs, we design pragmatic and proportionate ESG starter programmes that generate real value without unnecessary bureaucratic burden.
Double materiality requires companies to assess ESG topics from two angles: impact materiality (how the company's activities affect people, the environment, and society) and financial materiality (how ESG risks and opportunities affect the company's financial performance and position). CSRD compliance requires reporting on all topics identified as material from either perspective. This is a significantly broader scope than the single financial materiality required under IFRS.
For a company starting from scratch, we recommend allowing 9-12 months for the first full cycle: double materiality assessment (2-3 months), data collection system design and testing (3-4 months), and report drafting and verification preparation (3-4 months). Companies that have been producing voluntary sustainability reports under GRI may be able to complete the CSRD transition in 6-9 months.
CSRD requires member states to implement effective, proportionate, and dissuasive penalties for non-compliance, including financial penalties. In Spain, the regulatory framework is being transposed into national law. The reputational risk of non-compliance -- particularly for listed companies and those with institutional investor scrutiny -- is likely to be as significant as the formal penalty regime.
