CSDS for SMEs: What CSDS 1 and 2 Mean, Who Must Comply, and How to Start
Canadian sustainability reporting is moving from broad commitments toward more structured disclosure. For small and medium-sized enterprises, the immediate question is practical: will these standards apply directly, or will they show up indirectly through customers, lenders, and procurement processes?
The Canadian Sustainability Disclosure Standards are not just a public company issue. Large companies may be first in line, but their reporting often relies on information from suppliers. That means SMEs may feel the effects through supplier questionnaires, contract renewals, emissions data requests, and risk assessments before they ever face a formal reporting rule.
This post explains what CSDS 1 and CSDS 2 cover, who they apply to now, and how SMEs can start preparing without overbuilding a reporting program.
What the Canadian Sustainability Disclosure Standards are
The Canadian Sustainability Standards Board, or CSSB, was created to develop sustainability disclosure standards for use in Canada. Its first two standards are based on the International Sustainability Standards Board’s IFRS S1 and IFRS S2, with Canadian modifications.
The two standards are:
Standard | Full name | Main focus |
CSDS 1 | General Requirements for Disclosure of Sustainability-related Financial Information | How an organization reports material sustainability-related risks and opportunities |
CSDS 2 | Climate-related Disclosures | What an organization reports about climate-related risks and opportunities |
The CSSB describes these standards as part of Canada’s sustainability disclosure framework. The standards are available through the CSSB and the Canadian Standards Association, now commonly referred to as CSA Group. Useful source pages include the CSSB sustainability standards page, the CSSB project page for Canadian Sustainability Disclosure Standards, and CSA Group’s standard listings for CSA CSDS 1 and CSA CSDS 2.
In plain terms, the standards are designed to help organizations disclose sustainability-related information that could affect their financial prospects. This includes matters that could influence cash flows, access to financing, cost of capital, business continuity, asset values, customer demand, or regulatory exposure.
They are not general purpose social responsibility reports. They focus on sustainability-related financial information.
That distinction matters for SMEs. A customer questionnaire may ask broad environmental, social, and governance questions, but the CSDS framework is mainly concerned with risks and opportunities that are financially relevant to the reporting entity.
CSDS 1 sets the foundation for sustainability-related financial disclosure
CSDS 1 is the general standard. It explains how an organization should disclose sustainability-related risks and opportunities that could reasonably be expected to affect its prospects.
It functions as the base Sustainability Disclosure Standard for Canada. CSDS 2 then adds specific climate-related requirements.
CSDS 1 is built around four core areas.
Governance explains oversight and accountability
The governance section asks how the organization oversees sustainability-related risks and opportunities.
For a large public company, this may include board committees, executive accountability, internal controls, and reporting lines. For an SME, the equivalent may be simpler. It could involve the owner, general manager, operations lead, or finance lead.
The key question is not whether the organization has a complex governance structure. It is whether someone is responsible for identifying, monitoring, and responding to relevant sustainability risks and opportunities.
For example, a food processor may need to monitor water availability, energy costs, packaging rules, and major customer requirements. CSDS 1 would expect disclosure of how those issues are overseen if they are financially material.
Strategy explains how sustainability issues affect the business
The strategy section asks how sustainability-related risks and opportunities affect the organization’s business model, plans, and financial outlook.
This includes short-, medium-, and long-term effects. It may cover issues such as:
supply chain disruption
changing customer requirements
new regulations
resource constraints
market shifts
technology changes
financing conditions
For SMEs, this part can feel abstract. A practical way to think about it is to ask: which sustainability issues could affect sales, costs, operations, insurance, financing, or customer retention?
A metal fabricator that relies on energy-intensive processes may face exposure to energy prices, emissions expectations, and requests from customers tracking their supply chain emissions. A farm supplier may face weather-related delivery disruptions. A packaging company may face changing rules on recycled content or product design.
CSDS 1 does not require every sustainability topic to be treated equally. It focuses on those that could reasonably affect financial performance or position.
Risk management explains the process
The risk management section asks how the organization identifies, assesses, prioritizes, and monitors sustainability-related risks and opportunities.
This does not mean every SME needs a formal enterprise risk management department. Still, the standard expects a clear process.
That process may include:
tracking customer sustainability requirements
monitoring relevant regulations
assessing supplier or transportation risks
reviewing energy, fuel, and waste costs
documenting incidents and corrective actions
assigning responsibility for data collection
For a smaller company, a basic risk register can be enough to start. The value comes from consistency. If a major customer asks how the business manages climate-related disruption or resource use, documented processes are more credible than informal statements.
Metrics and targets explain how performance is measured
The metrics and targets section asks what the organization uses to measure, manage, and monitor relevant sustainability matters.
Metrics could include energy consumption, fuel use, waste volumes, water use, injury rates, product defect rates, or supplier compliance results, depending on the risks and opportunities identified.
Targets are not always required for every subject. If an organization has set a target, such as reducing electricity use or increasing recycled material, the standard expects clear disclosure of the target and progress against it.
For SMEs, the most useful starting point is often operational data that already exists. Utility bills, fuel receipts, waste invoices, maintenance logs, production volumes, and purchasing records can support basic metrics.
CSDS 2 focuses on climate-related disclosure
CSDS 2 deals specifically with climate-related risks and opportunities. It follows the same broad structure as CSDS 1: governance, strategy, risk management, and metrics and targets. The difference is that every section is focused on climate.
Climate disclosure can include both transition risks and physical risks.
Transition risks relate to the shift toward a lower-carbon economy. These may include carbon pricing, clean technology adoption, changing customer preferences, procurement rules, energy costs, and product standards.
Physical risks relate to climate impacts such as flooding, wildfires, heat, storms, or water stress. These risks may affect facilities, transportation routes, workforce safety, inventory, or insurance.
CSDS 2 also addresses climate-related opportunities. These could include lower energy costs, new customer requirements for lower-carbon inputs, process improvements, waste reduction, or access to markets that prefer suppliers with better climate data.
Greenhouse gas emissions are a central part of CSDS 2
One of the most visible parts of CSDS 2 is greenhouse gas, or GHG, emissions disclosure.
Emissions are commonly grouped into three scopes:
Scope | What it covers | SME examples |
Scope 1 | Direct emissions from sources the organization owns or controls | Natural gas used on site, diesel used in company vehicles |
Scope 2 | Indirect emissions from purchased energy | Electricity bought from the grid |
Scope 3 | Other indirect emissions across the value chain | Purchased materials, shipping, waste, business travel, product use |
Large companies often find Scope 3 the hardest to measure because it depends on information from suppliers, customers, logistics providers, and product users. This is where SMEs may see the greatest indirect impact.
A large manufacturer reporting under CSDS 2 may need information about the emissions associated with purchased goods and services. If an SME supplies parts, packaging, ingredients, transportation, maintenance, or materials, it may be asked to provide data that supports the customer’s Scope 3 estimates.
Scenario analysis and resilience may appear in customer requests
CSDS 2 also includes climate resilience concepts, including how an organization assesses its ability to respond to climate-related changes. Larger companies may use scenario analysis to test how different climate futures could affect their strategy.
SMEs may not be asked to produce a full scenario analysis. More likely, customer questionnaires may ask narrower questions such as:
whether the supplier has assessed climate risks
whether facilities are exposed to flooding, wildfire, or extreme heat
whether contingency plans exist for disruptions
whether emissions reduction plans are in place
whether energy use and fuel use are tracked
These questions help large companies understand their own exposure through the supply chain.
Who these standards apply to now
The CSSB develops standards, but it does not itself make them mandatory for every organization in Canada. The legal requirement to use sustainability disclosure standards depends on regulators, governments, lenders, investors, or contractual requirements.
At present, SMEs in Canada are generally not directly required by the CSSB to report under CSDS 1 or CSDS 2 simply because the standards exist.
Direct requirements are more likely to affect organizations such as:
reporting issuers, if securities regulators adopt requirements
federally or provincially regulated entities, where regulators introduce climate or sustainability disclosure rules
organizations that voluntarily adopt the standards
organizations required by investors, lenders, customers, or contracts to provide aligned information
For public companies, the Canadian Securities Administrators and individual securities regulators are central to any mandatory securities disclosure requirements. For financial institutions, prudential regulators may also set climate-related expectations. Those processes are separate from the CSSB’s role as a standard setter.
For SMEs, the current impact is often indirect. The standards may shape what large companies ask for, even when the SME has no direct statutory duty to prepare a CSDS report.
This distinction is important. An SME does not need to assume it must immediately publish a complete CSDS 1 and CSDS 2 report. It may need to prepare credible, consistent information for customers that are building their own disclosures.
How supplier questionnaires will affect SMEs
Supplier questionnaires are likely to be the main way many SMEs encounter these standards.
Large companies preparing sustainability or climate disclosures need data from across their value chain. Procurement teams may translate disclosure requirements into questionnaires, scorecards, supplier codes of conduct, contract clauses, or data upload portals.
These requests may not mention CSDS by name. They may still be influenced by it.
Common questions may include:
Does the company measure Scope 1 and Scope 2 GHG emissions?
Can it provide product-level or facility-level emissions data?
Does it track electricity, natural gas, diesel, gasoline, propane, or refrigerant use?
Has it set emissions reduction targets?
Does it have an environmental policy?
Who is responsible for climate or sustainability issues?
Has it assessed physical climate risks at key sites?
Does it have business continuity plans for weather-related disruption?
Can it provide evidence, such as utility bills, certificates, or supplier declarations?
Some customers may start with simple yes-or-no questions. Others may ask for numeric data. Larger buyers may require suppliers to use specific platforms or accepted calculation methods.
This creates several practical challenges for SMEs.
Data may be available but scattered
An SME may already have much of the information needed, but it may sit in separate places. Finance holds utility bills. Operations tracks production volumes. Fleet managers hold fuel records. Maintenance teams know equipment details. Waste contractors provide pickup reports.
Supplier questionnaires can become difficult when no one has a single source of information.
Questions may not fit smaller businesses well
Some questionnaires are designed for large organizations. They may ask about board committees, audited emissions inventories, or formal climate transition plans. SMEs may need to answer accurately without overstating their systems.
A neutral response is usually better than a vague claim. For example, “Energy use is tracked through monthly utility invoices and reviewed by operations management” is clearer than “We are committed to sustainability.”
Contract pressure may arrive before regulation
A supplier may not face a direct legal reporting duty, but it may face commercial pressure. A customer may prefer suppliers that can provide emissions data, meet documentation requirements, or show improvement over time.
This does not mean every SME will lose business without a full sustainability report. It does mean basic readiness may become part of supplier management.
Three steps SMEs can take to start adapting
SMEs do not need to copy the reporting systems of large issuers. A practical starting point is to build a basic information base that can answer customer questions and support future improvements.
Step 1. Identify which requests and risks are most relevant
Start with the business relationships most likely to drive disclosure expectations.
Review:
major customer contracts
supplier codes of conduct
procurement questionnaires
lender or insurer requests
industry association guidance
regulatory requirements that may apply to the sector
Then identify the sustainability and climate issues most likely to affect the business financially. For many SMEs, these may include energy costs, fuel use, waste, transportation, water use, weather disruption, packaging rules, or customer-specific emissions expectations.
The output can be simple: a one-page list of priority topics, why they matter, who owns them internally, and what data is already available.
Step 2. Build a basic data file with evidence
Next, collect the data most likely to be requested.
A starting file could include:
electricity and natural gas use
diesel, gasoline, propane, or other fuel use
refrigerant top-ups, if relevant
waste and recycling volumes, where available
water use, where material
production or service activity levels
site locations and key physical risks
existing policies, procedures, permits, or certifications
Keep evidence with the data. Supplier questionnaires often ask for support. That may include invoices, meter readings, utility summaries, waste reports, equipment lists, or written procedures.
A spreadsheet is usually enough at the beginning. The main goal is to make the information consistent, reviewable, and easy to update.
Step 3. Create a repeatable response process
Once the first questionnaire arrives, it is tempting to answer quickly and move on. A better approach is to save the responses and create a repeatable process.
Assign responsibility for:
receiving supplier sustainability requests
checking whether answers are accurate
updating energy and fuel data
storing evidence
approving claims before they are sent
tracking gaps that need follow-up
This reduces the risk of inconsistent answers between customers. It also helps avoid unsupported claims.
If a question asks for information the business does not yet track, state that clearly and consider whether it should be added to the data file. Over time, repeated customer questions will show which data points matter most.
A measured approach works best
CSDS 1 and CSDS 2 are part of a broader shift toward structured sustainability-related financial disclosure in Canada. For now, most SMEs are unlikely to be directly required to publish full reports under these standards unless a regulator, investor, lender, or contract requires it.
The more immediate issue is supply chain reporting. Large companies need better information about their risks, emissions, and value chains. That need will often reach SMEs through questionnaires and procurement reviews.
A practical response is to start small, stay accurate, and keep evidence. Identify the topics that matter, collect the data that customers are most likely to request, and create a repeatable process for answering. That approach prepares SMEs for current supplier expectations and leaves room to adapt if formal requirements expand later.
