Environmental responsibility is becoming an essential component of business strategy. Organizations across industries are increasingly expected to understand, measure, and communicate their environmental impact.

With new regulations like California’s SB 253 requiring Scope 1, 2, and 3 emissions disclosure, organizations are moving quickly from high-level estimates to audit-ready reporting. This shift is increasing demand for tools that can deliver complete, defensible emissions data across operations and supply chains.

IMPLAN supports this need by linking greenhouse gas emissions directly to economic activity, enabling users to quantify environmental impact across industries and regions.

IMPLAN’s environmental data allows users to calculate emissions associated with economic activity across all industries. Emissions are expressed in carbon dioxide equivalents, ensuring consistency across greenhouse gases and alignment with widely accepted reporting standards.

By connecting emissions to spending, production, and supply chains, IMPLAN provides a scalable way to understand environmental impact, even in complex global operations.

Introducing the GHG Emissions Guide

To support organizations preparing for emissions disclosure, IMPLAN now offers a Greenhouse Gas (GHG) Emissions Guide within the application.

This guided workflow enables teams to:

• Generate Scope 1 and 2 emissions estimates immediately (Scope 3 coming soon)
• Fill supply chain data gaps using spend-based modeling
• Refine results with company-specific inputs
• Produce audit-ready outputs aligned with GHG Protocol standards

Rather than assembling fragmented datasets or relying on incomplete supplier information, users can move from initial estimates to reporting-ready results through a structured, repeatable process.

Scope 1, 2, and 3 Emissions in IMPLAN

Scope 1 emissions represent direct emissions from owned or controlled sources such as fuel use, manufacturing processes, and company vehicles. These emissions are typically the most straightforward to measure and are directly tied to operational activity.

Scope 2 emissions capture indirect emissions from purchased energy, including electricity, heating, and cooling. These emissions reflect how energy sourcing decisions contribute to an organization’s overall footprint.

Scope 3 emissions include all other indirect emissions across the value chain, from purchased goods and services to transportation and downstream use.

Built for Reporting Confidence

IMPLAN delivers emissions totals across all industries, measured in carbon dioxide equivalents and aligned with established reporting frameworks.

In addition to calculating emissions, organizations must ensure their results can withstand third-party review. IMPLAN’s transparent methodology allows users to trace how emissions are derived, supporting audit readiness and reducing risk as disclosure requirements evolve.

By combining environmental data with economic modeling, IMPLAN provides both the numbers required for reporting and the context needed to understand their broader impact.

Why It Matters

Organizations are under increasing pressure to disclose their environmental impact to regulators, investors, and stakeholders.

At the same time:

• Scope 3 emissions often account for the majority of the total impact
• Supplier-level data is difficult and costly to obtain
• Reporting expectations are becoming more standardized and enforced
  

As requirements like SB 253 take effect, organizations must not only measure emissions but do so consistently and defensibly. Solutions that can scale across complex supply chains while aligning with global frameworks are becoming essential for compliance.

IMPLAN helps close this gap by providing comprehensive emissions coverage across industries and regions, enabling organizations to meet reporting requirements while gaining deeper insight into both environmental and economic impact.

From Insight to Compliance

IMPLAN’s environmental data provides a strong foundation for emissions analysis, but organizations increasingly need a clear path from analysis to reporting.

With the GHG Emissions Guide, teams can move from baseline estimates to audit-ready outputs by combining economic data, environmental metrics, and guided workflows within a single system. This transforms emissions analysis from a one-time exercise into a repeatable and scalable compliance workflow.
