Here’s a recommended approach based on your company size:
Smaller SMEs (up to 50 employees):
- Start with the free Business Carbon Calculator: This user-friendly tool provides a quick and easy estimate of your emissions. It's a great first step to understand your current footprint.
- Graduate to more precise data collection: As you become familiar with your emissions profile, consider collecting more detailed data directly from your operations.
Larger SMEs (over 50 employees):
- Focus on Scope 1 & 2 (direct & purchased Energy): Begin with a thorough review of these emissions, as you have the most control over them. This helps identify initial reduction opportunities and set targets.
- Expand to Scope 3 (value chain): To truly understand your impact, you’ll also need a handle on Scope 3 emissions. Start collecting data on relevant categories (e.g., business travel, purchased goods) as soon as possible.
Advanced Resources:
For comprehensive guidance on emissions quantification and management, look into the Greenhouse Gas Protocol (GHG Protocol). Their website offers valuable resources, including:
- Corporate Accounting and Reporting Standard: Provides a framework for measuring and reporting greenhouse gas emissions.
- Scope 3 Calculation Guidance: Offers detailed instructions for calculating Scope 3 emissions.
