How to Prepare for SEC Climate Disclosure: A Step-by-Step Guide

Introduction

The U.S. Securities and Exchange Commission adopted climate-related disclosure rules in March 2024. Legal challenges led to a stay of certain provisions while litigation continues. A coalition of nineteen state attorneys general has defended the rule, reflecting how material climate information has become for capital markets. Whether you are a large accelerated filer or building toward public-market readiness, the direction of travel is clear: investors expect consistent, decision-useful climate data tied to governance and risk management.

This guide outlines how venues, sports organisations, event operators, and municipalities can prepare operations and reporting so disclosure work is repeatable, auditable, and aligned with how your organisation already speaks to investors and stakeholders.

Step 1: Develop a repeatable data collection process

Documented, auditable, traceable

Disclosure depends on evidence, not narrative alone. Build a single source of truth for activity data (energy, fuels, refrigerants, fleet, purchased goods and services where relevant) with clear ownership, update cadence, and version control. Every figure in a filing or attestation should trace to an underlying record: invoice, meter read, supplier statement, or survey response.

For multi-site portfolios such as venue groups, leagues, or municipal departments, standardise definitions (what counts as operational control, boundaries, and materiality thresholds) so subsidiaries and partners submit comparable inputs. Internal audit and external assurance are far easier when the chain from raw data to reported metric is explicit.

Step 2: Organise GHG calculations with technology

Beyond static spreadsheets

Spreadsheets are a common starting point but they scale poorly across sites, seasons, and events. Carbon-focused enterprise systems (sometimes described as carbon ERP) centralise activity data, apply consistent methodologies, and retain calculation logic so year-on-year comparisons are valid.

Refresh emission factors and global warming values on at least an annual basis, aligned with recognised sources, and log each change. When regulators or auditors ask why a number moved, you should be able to separate real performance change from methodology or factor updates.

Step 3: Integrate GHG emissions into the investor disclosure process

One narrative, one set of numbers

Climate metrics should not live in a siloed sustainability report that disagrees with the Form 10-K or other SEC filings. Align finance, legal, sustainability, and operations on the same boundaries, metrics, and rounding rules. Establish a disclosure calendar that mirrors your financial close so climate data is reviewed with the same rigour as revenue and costs.

For organisations that are not yet SEC registrants, this discipline still matters: lenders, sponsors, and public-sector partners increasingly ask for the same quality of evidence.

Understanding the compliance timeline

Phased effective dates

The rule phases in requirements by filer category. Large accelerated filers (LAFs) are first, with obligations tied to fiscal years beginning in 2025 for certain disclosures. Accelerated filers (AFs) follow in subsequent fiscal years. Smaller reporting companies (SRCs) are exempt from the Scope 1 and Scope 2 emissions disclosure articles of the rule, though other climate-related disclosures may still apply depending on materiality and facts and circumstances.

Treat the timeline as a project plan: gap assessment, control design, limited assurance readiness (where applicable), and dry runs using prior-year data reduce last-minute risk.

What about Scope 3?

Still on the agenda for many organisations

The SEC final rule as adopted did not mandate Scope 3 disclosure in the same manner as earlier proposals. That does not remove downstream pressure. California’s Climate Corporate Data Accountability Act (SB 253) imposes Scope 1, 2, and 3 reporting obligations for large entities doing business in the state, with phased assurance requirements. International frameworks and investor questionnaires continue to request value-chain emissions.

Venues and events with significant supply chains, travel, and goods sourcing should map Scope 3 categories that matter to their stakeholders even when SEC Scope 3 articles do not apply directly.

How 50X Impact helps

Framework-exact reporting and automated calculations

50X Impact is built for organisations that need deterministic AI for compliance work: the same inputs produce the same disclosed numbers every time, and the system generates framework-exact reports rather than approximations. Our platform supports automated GHG Protocol-aligned calculations, preserves audit trails from source data to reported totals, and produces outputs that match the structure major frameworks expect. That combination reduces manual rework before filing deadlines and supports teams that must satisfy both regulatory filings and sponsor or league sustainability commitments.
