How Often Should a Carbon Reduction Plan Be Updated?

A Carbon Reduction Plan (CRP) should not be viewed as a document that’s written once and then forgotten. To remain accurate, compliant and useful, it should be reviewed and updated regularly to reflect your organisation’s latest emissions data, sustainability initiatives and business changes.

For organisations bidding for public sector contracts under Procurement Policy Note (PPN) 06/21, keeping a Carbon Reduction Plan up to date is particularly important. An outdated plan may not accurately represent your environmental performance and could undermine confidence in your commitment to achieving Net Zero.

In this guide, we’ll explain how often a Carbon Reduction Plan should be updated, what information should be reviewed and why regular updates benefit both compliance and long-term sustainability.

Why Updating Your Carbon Reduction Plan Matters

Your business is constantly evolving.

You may:

  • Employ more people.
  • Open new premises.
  • Replace company vehicles.
  • Switch energy suppliers.
  • Introduce new manufacturing processes.
  • Work with different suppliers.
  • Invest in renewable energy.

Each of these changes can affect your greenhouse gas emissions.

If your Carbon Reduction Plan isn’t updated to reflect these developments, it quickly becomes less accurate and less valuable.

Keeping it current demonstrates that sustainability is an ongoing business priority rather than a one-off exercise.

How Often Should a Carbon Reduction Plan Be Reviewed?

As a general rule, organisations should review their Carbon Reduction Plan at least once a year.

An annual review allows you to:

  • Update your emissions data.
  • Measure progress against reduction targets.
  • Record new sustainability initiatives.
  • Identify opportunities for further improvement.
  • Demonstrate continual progress towards Net Zero.

Many organisations choose to align this review with their financial year or annual reporting cycle, making it easier to collect accurate business data.

When Should You Update Your Carbon Reduction Plan Sooner?

Although an annual review is recommended, there are situations where your Carbon Reduction Plan should be updated earlier.

Examples include:

Significant Business Growth

If your organisation expands rapidly, acquires another business or opens additional locations, your emissions profile may change significantly.

Updating your Carbon Reduction Plan ensures it accurately reflects the current business.

Major Operational Changes

Changes such as:

  • New manufacturing equipment.
  • Fleet replacements.
  • Office relocations.
  • Renewable energy installations.

can all affect your carbon footprint.

Changes to Sustainability Strategy

Many businesses introduce new environmental initiatives throughout the year.

For example:

  • Installing solar panels.
  • Introducing electric vehicles.
  • Improving recycling.
  • Changing suppliers.
  • Implementing energy-saving measures.

Updating your Carbon Reduction Plan allows these achievements to be recorded.

New Procurement Opportunities

If you’re preparing to bid for an important public sector contract, it’s good practice to review your Carbon Reduction Plan beforehand to ensure all information is accurate and up to date.

What Should Be Reviewed During an Update?

An annual review should consider every section of the Carbon Reduction Plan.

This includes:

Carbon Emissions

Review Scope 1, Scope 2 and relevant Scope 3 emissions.

Ensure calculations are based on the latest available data.

Carbon Reduction Initiatives

Update any projects that have been completed and add any new initiatives introduced since the previous review.

Reduction Targets

Assess whether existing targets remain realistic and achievable.

If appropriate, revise future objectives to reflect changing business priorities.

Governance

Review who is responsible for delivering the Carbon Reduction Plan and ensure responsibilities remain clear.

Net Zero Commitment

Confirm that your long-term commitment remains appropriate and aligned with organisational objectives.

The Benefits of Regular Updates

Updating your Carbon Reduction Plan isn’t simply about maintaining compliance.

It also provides valuable business insights.

Benefits include:

  • Better understanding of emissions trends.
  • Improved decision-making.
  • Stronger ESG reporting.
  • Increased stakeholder confidence.
  • Better procurement readiness.
  • Demonstrable progress towards Net Zero.

Businesses that regularly review their Carbon Reduction Plans are often better placed to identify cost-saving opportunities through reduced energy use and improved operational efficiency.

Common Mistakes When Updating a Carbon Reduction Plan

Many organisations review their Carbon Reduction Plans but overlook important details.

Common mistakes include:

  • Reusing outdated emissions data.
  • Forgetting to include new sustainability initiatives.
  • Not reviewing Scope 3 emissions.
  • Failing to update reduction targets.
  • Treating the review as an administrative task rather than a strategic exercise.

Avoiding these mistakes helps ensure your Carbon Reduction Plan continues to provide genuine value.
