Climate, water, and forests overlap

Lesson 3.3

Key takeaway

The 2026 unified questionnaire is one form, but it covers five themes. Most companies have material exposure on more than one. A food and beverage company has climate exposure (energy and refrigeration), water exposure (irrigation and processing), and forests exposure (commodity sourcing). Most first-time responders treat each theme as a separate workstream, then bolt them together at the end. The companies that score well treat them as one integrated assessment. This lesson explains how to do that without doubling the work.

Why themes overlap more than they look

The five themes (climate, forests, water, plastics, biodiversity) are not independent silos. They are interconnected systems of environmental impact, often acting on the same underlying value chain.

IndustryClimateForestsWaterPlasticsBiodiversity
FMCG / FoodHigh (energy, refrigeration)High (palm, soy, paper, cocoa)High (processing, agri inputs)High (packaging)High (agri sourcing)
ApparelMedium-high (energy, transport)Medium (viscose, leather)High (cotton, dyeing)Medium (synthetics)Medium-high (cotton, leather)
Steel / CementVery high (process and energy)LowMedium-high (cooling)LowMedium (mining sites)
Financial servicesHigh (financed emissions)Medium (sector exposures)Medium (sector exposures)LowMedium (sector exposures)
Real estateHigh (operational + embodied)Medium (timber)Medium (operational)LowMedium (site footprint)

The "high" cells are where you have to disclose substantively under that theme. Most large companies have at least three "high" cells. The unified questionnaire asks you to address them all in one response.

What CDP wants in a cross-theme assessment

CDP's IRO module questions and the cross-cutting strategy questions in Module 5 reward responses that show:

  • Joint assessment. You ran one risk assessment that looked at climate, water, forests, plastics, and biodiversity together, not five separate exercises stitched together.
  • Connected risks. You identify cases where one theme's risk amplifies another. Drought (water) reduces hydropower (climate). Deforestation (forests) reduces biodiversity habitat (biodiversity) and changes regional rainfall (water).
  • Shared mitigation. Your transition plan addresses multiple themes with the same actions. Switching to regenerative agriculture reduces emissions, restores soil biodiversity, and cuts irrigation needs.
  • Aligned governance. The same board committee oversees all environmental themes, not separate committees for each.

Analogy

Think of the five themes like the gauges on a car dashboard. Speed, fuel, engine temperature, oil pressure, battery. They are different metrics, but they all describe the same vehicle. A driver who only watches speed will miss the engine warning. CDP wants companies that watch the whole dashboard, not just one gauge.

A practical workflow for cross-theme assessment

The companies that handle this well follow a similar pattern:

  1. One assessment, one workshop. Bring environmental, operational, procurement, and strategy leads into one room (or one virtual workshop). Walk through every theme using shared tools (TCFD-aligned scenario for climate, ENCORE for nature dependencies, WRI Aqueduct for water, CDP Forests Risk methodology for commodity sourcing). Document themes side-by-side, not in separate documents.

  2. A unified risk register. Maintain a single spreadsheet or risk system entry per identified risk, with columns for primary theme, secondary themes, financial impact, time horizon, mitigation owner, and review date. This makes it easy to disclose the same risk across multiple theme questions in CDP without inconsistency.

  3. Linked mitigation actions. When you identify a mitigation action, note which themes it addresses. Regenerative agriculture is climate + forests + water + biodiversity. An energy efficiency investment is climate + (often) water (cooling) + plastics (lower packaging if linked to product lightweighting).

  4. One narrative. Your CDP response should read as one company speaking about its environmental footprint, not five reports on different themes pasted together. The grader notices this.

Worked example: the cross-theme upgrade

Worked example

SaaSFood Ltd, India (synthetic, but representative of mid-size F&B).

Year 1 approach. Sustainability lead wrote each theme in isolation. Climate was strong (a real Scope 1+2+3 inventory, validated SBTi target). Water was a paragraph because the team had not done water risk work yet. Forests was a paragraph because they assumed it did not apply (they source palm oil through a distributor and "trust the distributor"). Biodiversity was blank.

Result: B-minus on climate, C on water, D on forests, no biodiversity disclosure.

Year 2 approach. Same team, same data. They run one workshop with operations, procurement, and external advisors. Findings:

  • The same farms in Maharashtra that supply their tomato processing are exposed to water stress (water risk) and to regional rainfall change (climate risk) and to soil biodiversity loss (biodiversity risk). These are the same fields.
  • Their palm oil distributor sources from Indonesia, which means they have direct deforestation exposure even without owning land. The "we trust the distributor" answer is not credible.
  • Their cooling and refrigeration uses HFC refrigerants (climate risk) and energy from coal-heavy grids (climate risk) and water for evaporative cooling (water risk).

The Year 2 response describes one integrated assessment. Climate goes from B-minus to B-plus. Water goes from C to B. Forests goes from D to C-plus (still developing but credible). Biodiversity gets a first disclosure. The total improvement is a full letter grade across the unified score.

The work added: one workshop, one risk register, one transition plan revision. No new content was invented; existing knowledge was just connected.

The risks of treating themes separately

Companies that keep themes in silos run into three predictable problems:

  • Inconsistent disclosure. The climate response says "we have full traceability of agricultural sourcing" because the climate team used Scope 3 inventory data. The forests response says "we have limited Tier 2 visibility" because the procurement team is more honest about reality. Same company, conflicting answers.

  • Missed leadership points. Several Leadership-tier criteria reward cross-theme thinking explicitly. A response that addresses climate and biodiversity in one mitigation action scores higher than one that addresses each separately, even if the two responses describe the same action.

  • Double work in future cycles. Five separate annual workstreams cost five times the project management. One integrated workstream is cheaper to maintain.

There are cases where one theme genuinely does not apply or is genuinely material at a different level. A pure software company may have negligible water and forests exposure. A coal mining firm may have negligible plastics exposure. Saying "this theme is not material to our business based on our materiality assessment" is a valid disclosure when it is true. The grader penalises pretending themes apply when they do not, just as much as ignoring themes that do. The honesty test: would you accept your competitor saying the same thing?

Frameworks that help

Cross-theme assessment is easier when you use frameworks that already think in connected terms. Useful tools:

  • TCFD and IFRS S2 for climate, with scenario analysis methodology.
  • TNFD for biodiversity and broader nature, with the LEAP framework that explicitly covers water, forests, and biodiversity.
  • ENCORE (Natural Capital Finance Alliance) for sector-level nature dependency mapping.
  • WRI Aqueduct for water risk by basin.
  • Forest 500 (Global Canopy) for benchmarking commodity-driven forest risk.
  • SBTi Forest, Land and Agriculture (FLAG) for joint targets covering land-use emissions and biodiversity.

Using two or three of these in your IRO process and citing them in your CDP response signals to the grader that you are operating with current best practice tools, not improvising.

Key Takeaways

  1. The five CDP themes overlap heavily for most large companies, especially in food and consumer goods sectors
  2. CDP rewards joint assessment of themes, connected risks, shared mitigation, and aligned governance
  3. A unified risk register with theme tags makes cross-theme disclosure consistent across the questionnaire
  4. The companies that handle this well do one workshop, not five; the work to integrate is mostly process, not new substance
  5. Use frameworks (TCFD, TNFD, ENCORE, Aqueduct, SBTi FLAG) that already think in connected terms; cite them in your response
