CDP Score Explained: How Scoring Works and How to Improve Yours

Your CDP score is one of the most visible environmental ratings your company carries. Investors screen on it, customers ask about it and the best performers put it front and center in reports and sales conversations. For the 2025 cycle, nearly 20,000 companies were scored, and fewer than one in twenty made the A List.

This article explains what a CDP score measures, how it’s calculated, what separates an A from a B, and where to focus to move up.

What Is a CDP Score?

A CDP score is a letter grade, from A to D-, that rates how completely a company discloses and how advanced its environmental management is. CDP scores each scored theme separately, so a company can hold one score for climate change, another for water security and another for forests.

A CDP score is not a pure measure of emissions. A high emitter with rigorous governance, verified data, credible targets and a funded transition plan can outscore a lower emitter that discloses poorly. The score rewards transparency, process maturity and action.

The CDP Scoring Scale

How CDP Scores Are Calculated

Scoring Level by Level

Each scored question can earn points at up to four levels: Disclosure, Awareness, Management and Leadership. Your response is assessed level by level, and you must reach a minimum threshold at one level before you can be scored at the next.

Sector-Specific Methodologies

CDP tailors questions and scoring by sector, using its Activity Classification System. A utility, a bank and a food company are measured against criteria relevant to their impacts, so benchmark against sector peers rather than the whole market.

Essential Criteria

Certain requirements act as gates. Miss an essential criterion and your score is capped at a lower band, no matter how well you answer everything else. For climate Leadership, these typically include elements such as:

• Third-party verification of Scope 1 and 2 emissions and relevant Scope 3 categories
• A credible transition plan that shows how you’ll reach your targets
• Ambitious emissions targets, such as validated science-based targets

CDP publishes its essential criteria and full scoring methodology each year.

What’s Changed in CDP Scoring for 2026

• SMEs can now earn an SME A for climate change, a new top grade for smaller companies (not equivalent to the full corporate A)
• Cocoa, coffee and rubber join cattle, palm oil, soy and timber as scored forest commodities
• A new aviation sector questionnaire with improved target scoring
• Ocean, plastics and biodiversity questions remain unscored in 2026
• GHG verification under ESRS is accepted for EU Member States

Scored themes remain climate change, forests and water security. CDP does not expect major questionnaire changes for 2027, so these updates are your best guide for next year’s response.

What Is a Good CDP Score?

• A or A-: Leadership. An elite position that signals best practice to investors and customers
• B or B-: Management. A solid score showing coordinated, active environmental management
• C or C-: Awareness. Shows understanding but limited action
• D or D-: Disclosure only. The starting point for first-time responders

A practical goal for most enterprises is to move up at least one band per cycle by closing the gaps that cap your score.

How to Improve Your CDP Score

Start With a Gap Analysis

Your score report shows where you earned and lost points. Map each lost point to a cause: missing data, weak narrative, an unmet essential criterion or a structural gap such as no transition plan.

Fix the Gates First

Essential criteria cap everything else. If you lack third-party verification or approved targets, address those before polishing answers elsewhere.

Get Verification-Ready

Verification requires numbers that trace back to source data. Without lineage, verification is slow, expensive and risky. With the 2027 scoring deadline moving to the week of July 26, verification statements need to be in hand about seven weeks earlier than in past cycles.

Strengthen Scope 3

Move your most material categories from spend-based estimates toward supplier-specific data, and explain methodology and coverage clearly.

Make Answers Specific

Quantify, cite documents and explain changes. Vague or blank answers leave points on the table.

Keep Your Story Consistent

Scorers and stakeholders notice when CDP figures don’t match your annual report or regulatory filings. One source of truth solves that.

Build the Foundation for a Higher CDP Score

Higher CDP scores come from better systems, not better writing. Leadership requires verified emissions, credible targets and transition plans, all built on data you can defend.

Novisto gives enterprise teams that foundation. Its audit-grade data lineage makes every number, decision and calculation traceable and defensible. Integrated carbon accounting calculates Scope 1, 2 and 3 emissions in the same system you report from. And performance tools help you track targets, identify emissions hot spots and benchmark against peers, so your score reflects real progress.
