EU 2040 Climate Target: A Business Guide to 90% Emissions Reduction & CSRD Compliance

Introduction: Navigating the EU's Ambitious 2040 Climate Target

The European Union has solidified its climate ambition with a landmark amendment to the EU Climate Law, establishing a binding target to reduce greenhouse gas (GHG) emissions by 90% by 2040, compared to 1990 levels. This target, approved by the European Council, builds upon the existing 55% reduction goal for 2030 and the overarching climate neutrality objective for 2050. For businesses operating in or with the EU, this represents a significant regulatory shift that will directly impact strategic planning, operational costs, and reporting obligations. This guide provides a comprehensive, step-by-step approach to understanding and aligning with the 2040 target, focusing on the critical interplay with the Corporate Sustainability Reporting Directive (CSRD), European Sustainability Reporting Standards (ESRS), and related frameworks. You will learn how to establish robust emissions tracking, develop credible reduction strategies, and ensure compliance in an evolving regulatory landscape.

Prerequisites: Understanding the EU Regulatory Ecosystem

Before diving into implementation, businesses must grasp the foundational regulations and standards that govern sustainability in the EU. This target does not exist in isolation; it is part of a broader, interconnected regulatory framework.

• EU Climate Law (Amendment): The binding legal instrument setting the 90% GHG reduction target by 2040. It introduces key flexibilities, including the allowance to use international carbon credits under Article 6 of the Paris Agreement for up to 5% of the reduction target from 2036 onward. It also includes provisions like the one-year delay to the launch of ETS2 (the extension of the EU Emissions Trading System to road transport and building heating fuels) from 2027 to 2028.
• Corporate Sustainability Reporting Directive (CSRD): Directive (EU) 2022/2464. This is the core reporting mandate. It requires in-depth sustainability disclosures from a wide range of companies based on a double materiality assessment. Applicability is phased: for the 2024 reporting year (reports published in 2025) for large public-interest entities; for the 2025 reporting year (reports in 2026) for other large companies; and for the 2026 reporting year (reports in 2027) for listed SMEs.
• European Sustainability Reporting Standards (ESRS): The detailed reporting standards under CSRD. The first set of 12 standards was adopted in July 2023. They include cross-cutting (ESRS 1, ESRS 2), environmental (E1-E5), social (S1-S4), and governance (G1) standards. Reporting against ESRS is mandatory for material topics.
• EU Emissions Trading System (ETS & ETS2): The cap-and-trade system for controlling industrial GHG emissions. ETS2 will extend coverage to road transport and buildings, with its start now delayed to 2028.
• Broader Context: Regulations like the UK's FCA Sustainability Disclosure Requirements (SDR) for asset managers, as highlighted in recent guidance, demonstrate a global trend toward stricter sustainability reporting and labeling, reinforcing the importance of robust internal ESG governance.

Step 1: Conduct a Double Materiality Assessment

The cornerstone of CSRD compliance is the double materiality assessment. This is not a one-time exercise but an ongoing process to identify which sustainability topics are material for your business.

• Define Materiality: Under CSRD, a topic is material if it meets either impact materiality (your company's impact on people and the environment) or financial materiality (how sustainability issues affect your company's financial value). Climate change and GHG emissions are almost always material.
• Process: Engage stakeholders (investors, customers, employees, communities). Analyze your value chain. Assess both current and potential future impacts and financial risks/opportunities related to climate change, energy use, and the 2040 target.
• Outcome: A documented materiality matrix that prioritizes topics. This directly informs which ESRS standards and disclosures you must report on. For climate, this will heavily involve ESRS E1 (Climate change).

Step 2: Establish Robust GHG Emissions Inventory (Scopes 1, 2 & 3)

You cannot manage or reduce what you do not measure. A comprehensive, accurate GHG inventory aligned with the Greenhouse Gas Protocol is non-negotiable.

Scope 1 & 2: Direct and Energy-Indirect Emissions

These are the most immediate emissions under your control or influence.

• Scope 1: Direct emissions from owned or controlled sources (e.g., company vehicles, on-site fuel combustion, industrial processes).
• Scope 2: Indirect emissions from the generation of purchased electricity, steam, heating, and cooling consumed by your company.
• Action: Collect data from utility bills, fuel purchases, and facility meters. Use emission factors (like those from the IPCC or DEFRA) to calculate CO2-equivalent. This data is required under ESRS E1.

Scope 3: Value Chain Emissions

Often the largest and most complex portion of a company's footprint, encompassing all other indirect emissions.

• Definition: Emissions from activities not owned or controlled by your company but occurring in your value chain (e.g., purchased goods/services, business travel, waste, use of sold products).
• Challenges: Data availability and quality from suppliers can be a major hurdle.
• Strategy: Start by screening all 15 Scope 3 categories defined by the GHG Protocol. Prioritize the most material categories. Engage suppliers for data, using questionnaires or industry-average data initially. Tools like Persefoni can automate data collection and calculation for complex Scope 3 inventories. Platforms like AIGovHub's ESG module can help manage supplier data requests and track progress against reduction targets.

Step 3: Set Science-Based Targets and Develop a Reduction Plan

With a baseline inventory, you must set targets that contribute to the EU's 90% goal.

• Science-Based Targets (SBTs): Align your company's GHG reduction targets with the latest climate science to meet the goals of the Paris Agreement. The Science Based Targets initiative (SBTi) is the leading verifier. Setting an SBT is a strong signal of commitment and is increasingly expected by investors and customers.
• Target Setting: Your targets should cover at least 95% of your Scope 1 and 2 emissions and material Scope 3 emissions. They should be ambitious, with a near-term (5-10 year) and a long-term (2040/2050) horizon.
• Reduction Plan: Develop a detailed roadmap. This may include: energy efficiency upgrades, switching to renewable electricity (via Power Purchase Agreements or green tariffs), fleet electrification, sustainable sourcing, product redesign, and circular economy initiatives. Remember the Climate Law flexibility: from 2036, you can plan for the use of high-quality international carbon credits to account for up to 5% of your reduction obligation, but this should be a last resort after maximizing internal abatement.

Step 4: Prepare CSRD-Compliant Reporting Under ESRS

Transparent disclosure is mandatory. Your CSRD report will be the primary vehicle for communicating your climate performance.

• Report Structure: Integrate your sustainability statement into the management report. It must be digitally tagged using XHTML with iXBRL.
• Key ESRS E1 Disclosures: You will need to report on: your climate transition plan, GHG emissions (Scopes 1, 2, 3), climate-related targets, and the financial effects of climate-related risks and opportunities. You must also describe how your business model and strategy are compatible with the transition to a sustainable economy and the 2040 target.
• Assurance: CSRD reports are subject to limited assurance (audit) initially, moving toward reasonable assurance. Ensure your data collection processes are auditable. Integrated reporting platforms like Workiva can streamline the collation, control, and audit trail of data from various sources into a final, assured report.

Step 5: Integrate Climate Governance and Risk Management

Compliance must be embedded into corporate governance.

• Board Oversight: The board and senior management must have explicit oversight of climate-related risks and the company's transition plan. This is a requirement under ESRS and is scrutinized by regulations like the UK FCA's SDR guidance, which emphasizes governance and escalation procedures.
• Risk Management: Integrate climate-related risks (physical and transition risks) into your enterprise risk management (ERM) framework. Conduct scenario analysis (e.g., using IPCC scenarios) to assess resilience under different warming pathways.
• Incentives: Link executive remuneration to the achievement of climate targets, as encouraged by ESRS and other frameworks.

Common Pitfalls to Avoid

• Underestimating Scope 3: Ignoring or poorly addressing value chain emissions is a major red flag for investors and regulators.
• Treating CSRD as a One-Off Reporting Exercise: CSRD requires a fundamental integration of sustainability into strategy and operations. It's a continuous management process.
• Relying Exclusively on Offsets: The EU Climate Law allows limited use of international credits from 2036, but a credible strategy prioritizes direct emissions reductions within your operations and value chain.
• Poor Data Governance: Inconsistent data sources, lack of audit trails, and manual spreadsheet processes lead to errors and fail assurance checks.
• Siloed Sustainability Teams: Climate strategy requires cross-functional collaboration (finance, operations, procurement, legal).

Frequently Asked Questions (FAQ)

How does the 2040 target affect my company if we are not based in the EU?

If your company has a subsidiary in the EU that meets the CSRD size thresholds, that entity will have to report. Furthermore, non-EU companies with significant turnover in the EU may be subject to the CSRD's third-country rules. More broadly, multinational customers and investors are increasingly demanding EU-aligned climate disclosures, making compliance a competitive necessity.

What is the difference between CSRD and the EU Climate Law target?

The EU Climate Law (with its 2040 target) sets the policy objective—the "what." The CSRD and ESRS provide the reporting framework—the "how" companies disclose their plans, performance, and progress toward that objective. They are intrinsically linked.

When do we need to start reporting under CSRD?

The timeline depends on your company's size and status. Large EU public-interest entities report for the first time in 2025 (covering the 2024 financial year). Other large companies report in 2026 (covering 2025). Listed SMEs report in 2027 (covering 2026). You should start preparations at least 12-18 months before your first reporting deadline.

Can we use carbon credits to meet our targets?

For your own corporate targets, high-quality carbon credits can be part of a strategy, but they should not replace internal reduction efforts. Notably, the amended EU Climate Law explicitly allows the use of international carbon credits under Article 6 of the Paris Agreement to account for up to 5% of the EU-wide 2040 reduction target from 2036 onward, providing a regulatory precedent for their limited, strategic use.

How do tools like AIGovHub help with ESG compliance?
