What is Plan A
Plan A is a carbon accounting and ESG management platform used to measure, manage, and report corporate greenhouse gas emissions and sustainability metrics. It supports emissions calculations across Scopes 1–3, supplier engagement workflows, and reporting aligned to common ESG and climate disclosure frameworks. The product targets sustainability teams and finance/operations stakeholders that need auditable data collection, calculation methodologies, and reporting outputs for internal management and external disclosures.
Scope 1–3 accounting coverage
The platform is designed to calculate and track emissions across Scopes 1, 2, and 3, supporting common activity data types and emissions factor-based calculations. This helps organizations consolidate emissions data in one system rather than relying on spreadsheets. It also supports ongoing tracking over time for target-setting and progress monitoring.
ESG reporting alignment support
Plan A supports ESG and climate reporting workflows that map data to widely used disclosure frameworks and stakeholder reporting needs. This can reduce manual effort when preparing recurring reports and evidence packs. The focus on structured data capture and reporting outputs aligns with how ESG reporting tools in this space are typically evaluated.
Supplier data collection workflows
The product includes capabilities aimed at collecting and managing supplier emissions data, which is often required for Scope 3 categories. Centralized supplier engagement can improve completeness compared with ad hoc email-based collection. This is particularly relevant for organizations with complex value chains where supplier data quality is a primary constraint.
Integration depth varies by stack
As with many carbon accounting platforms, the usefulness of the system depends on how well it connects to existing ERP, procurement, travel, and utility data sources. Organizations may need additional integration work or data engineering to automate data flows. This can extend implementation timelines, especially for multi-entity environments.
Methodology governance needs oversight
Carbon accounting requires consistent choices around boundaries, emissions factors, and calculation methods, and these decisions can materially affect results. Teams typically need internal governance to ensure methodologies remain consistent across business units and reporting periods. Without strong controls, comparability and audit readiness can be harder to maintain.
Scope 3 data quality constraints
Scope 3 estimates often rely on supplier-provided data or spend/average-data approaches when primary data is unavailable. The platform can structure collection and calculations, but it cannot fully resolve gaps in supplier responsiveness or data accuracy. Organizations should expect iterative improvement cycles rather than immediate high-confidence Scope 3 results.
