How to Improve Your CDP Score: A Practical Guide

What a CDP Score Is and Why It Matters for ESG Performance 

A Carbon Disclosure Project (CDP) score provides insights into a company’s environmental performance. It indicates how effectively an organisation manages climate change, water security, and deforestation risks. Companies of all sizes, from SMEs to large corporations, can participate voluntarily or be required to report a CDP score by investors or suppliers. 

Importance of ESG Performance 

CDP scores guide businesses to help prioritise sustainability actions and improve transparency. 

• Achieving high scores enables them to demonstrate accountability and strengthen trust with investors, stakeholders, and supply chains. 

• The scores also assist companies in benchmarking performance, thus managing climate-related risks and attracting sustainable investment. 

Moreover, the CDP rating aligns the businesses with global ESG standards to support informed decision-making and position them as leaders in environmental responsibility.

How CDP Scoring Works in Sustainability Reporting

The CDP scoring system evaluates the environmental performance of the companies and provides a benchmark for investors, regulators, and stakeholders. Scores range from D- to A, reflecting how effectively an organisation manages climate-related risks, sets targets, and discloses data. 

• A low score (D or C) indicates basic awareness or partial reporting

• Higher scores (B to A) demonstrate robust strategies, transparency, and measurable progress.

CDP assesses four key areas: 

• Disclosure

• Awareness

• Management

• Leadership

Companies submit detailed data on emissions, water usage, deforestation impact, and climate strategies. CDP then analyses the quality, completeness, and actionability of this information. High scores signal strong ESG practices and strategic climate management, enhancing credibility with investors and partners. 

Key Factors That Influence a Company’s CDP Score

A company’s CDP ESG ratings depend on stakeholder engagement, ability to manage risks, setting appropriate targets and more: 

Governance and Board Oversight

Strong corporate governance ensures the effective execution of climate strategies. This is reflected in boards by defining responsibilities, funding green initiatives, and maintaining transparent records.

Stakeholder Engagement

Active interaction with investors, customers, and suppliers strengthens alignment and shows commitment to sustainability across the value chain.

Risk Management

Identifying and assessing climate and environmental risks allows companies to understand potential operational impacts. Integrating these insights into ESG reporting improves resilience and signals preparedness to investors and stakeholders.

Targets and Metrics

Setting near- and long-term science-based targets for emissions, biodiversity, and resource use converts ambition into actionable plans. Daily tracking of energy, water, and waste, combined with circular economy initiatives, strengthens transparency and credibility.

Verification and Evidence

Independent audits, verified baselines, and third-party assurance letters strengthen credibility. CDP assesses these through documented policies, board minutes, and supplier engagement metrics, to ensure transparency and trust in reported data.

Common Mistakes That Lower CDP ESG Ratings

Common mistakes in CDP reporting lower scores and stakeholder trust. Companies often lose points due to weak governance, incomplete data, vague targets, or insufficient Scope 3 reporting. Understanding these points offers a solution to how to improve CDP score. 

Treating CDP as a Form

Many companies approach CDP like a checklist. The right way to approach this is by demonstrating how sustainability is embedded in operations, governance, and decision-making.

Avoiding Scope 3 Emissions

Lack of indirect emissions or giving vague answers downgrades the scores. Purchased goods, transportation, and use-phase emissions need to be shown.

Unverified or Inconsistent Data

Reporting GHG emissions without boundaries, third-party checks, or scope breakdown lowers the CDP score.

No Clear Climate Targets

Vague or CSR-style goals like “go green” won’t work. CDP wants time-bound and measurable targets.

Lack of Data Granularity

Reporting total figures without breakdowns by scope, region, or source loses points. Transparency and auditable data are key to strengthening credibility.

Weak or Missing Narratives

CDP evaluates qualitative disclosures. Blank or generic answers suggest climate action is not embedded in business operations. 

Practical Steps on How to Improve CDP Score Through Better Data and Governance

Improving your CDP score involves connecting climate action into business processes. 

Link Environmental Impacts

• Identify emissions hotspots across operations and supply chains. 

• Include Scope 1, 2, and 3 emissions, water usage, and waste streams. 

• Use internal dashboards or ESG software to consolidate data.

Define Governance Roles

• Assign clear responsibilities to sustainability teams, finance, and procurement.

• Ensure the board reviews progress quarterly and signs off on policies.

Set Science-Based Targets

• Define measurable and time-bound goals for emissions reduction, energy efficiency, and resource conservation. 

• Link targets to departments and performance metrics.

Validate and Audit Data

• Use third-party verification for emissions and water data. 

• Document assumptions, methodologies, and calculation frameworks.

Best Practices Companies Use to Achieve Higher CDP Ratings

Top-performing companies approach CDP as a strategic tool for improvement. Here are more insights for you to enhance CDP ESG ratings: 

Integrate Strategy Across Functions

Top-performing companies embed sustainability across operations, procurement, and product development. For instance, energy reduction in manufacturing can be achieved through implementing production KPIs, while FMCG firms optimise packaging to reduce Scope 3 emissions.

Centralised Data Management

High scorers consolidate environmental data on a single platform. This is ensured by tracking emissions, water, and waste per facility, fuel type, and region. Documentation of the assumptions, methodologies, and identified gaps exhibits traceability, transparency, and audit readiness.

Target-Driven Approach

Science-based time-bound targets offer desired outcomes. Departments must be held accountable, progress should be tracked regularly, and targets must also be integrated with financial planning to signal real business commitment.

Stakeholder Engagement

Companies must actively involve suppliers, partners, and key stakeholders, especially for Scope 3 impacts. Supplier audits, scorecards, and engagement programs reduce upstream risks while improving reporting credibility.

Quality Narratives and Evidence

Beyond numbers, companies must provide evidence like: 

• Policies

• Board minutes

• Case studies

• Verification letters. 

Clear and concise explanations of initiatives, KPIs, and results enhance transparency.

Continuous Improvement

Regular reviews, trial submissions, and cross-functional feedback help refine reporting. Companies that treat CDP as an ongoing performance tool can reach A-level ratings.

Key Takeaways on Improving CDP Score for Better ESG Performance

CDP scoring enhances business transparency, operational efficiency, and strategic ESG performance. Companies improve scores by embedding sustainability into core functions such as operations, procurement, and governance. Consolidated, accurate, and auditable data on Scope 1, 2, and 3 emissions, water usage, and waste delivers reliable insights to support decision-making and proactive risk management. 

Science-based and time-bound targets, along with supplier and partner engagement reduces upstream impacts and strengthens reporting credibility. Additionally, centralised tracking, continuous monitoring, and periodic validation keep data consistent and actionable.
