Communicating your ongoing journey

Announcing your certification is only the beginning. B Corp Certification is an ongoing commitment and a pledge for continuous improvement. There’s no need to wait for your impact report or recertification to speak about being a B Corp—read our tips on how to keep telling your story.

  • March is B Corp Month. B Lab will provide a toolkit with a theme and content ideas for you to use. It’s the perfect opportunity to share your journey and achievements. 

  • Report your progress. You don’t need to wait to share your progress in your impact report—write newsletters, blog posts or social posts updating employees, consumers, and other stakeholders on your endeavors and improvement. 

  • Follow B Lab and other B Corps online. Subscribe to newsletters, follow socials, and keep up-to-date with announcements and achievements within the community.

  • Join workshops, talks or attend events. Reach out to your local community hub or club to find out about opportunities to join events in person. 

People holding a global, symbolising collective action
  • Find opportunities to collaborate. Seek out fellow B Corps with co-branded product ideas. 

  • Join a collective. Find collective action campaigns and coalitions relevant to your industry or area.

  • Speak at a panel. Look for opportunities to pitch and speak about your sustainability commitments, and how B Corp Certification supports them (and invite your local B Lab team to join you!)

  • Throw a party. Celebrate your certification anniversary with a B Day Party for employees, customers, and other stakeholders. Think cake, a giveaway, or a day of service.


Share how you’ve been speaking about your certification with us or your local B Lab team.

Impact reports

Every year, B Corps are required to publish an impact report to share the company’s progress towards its social and environmental performance. This makes sure B Corps are accountable and transparent, reaffirming their commitment to continuous improvement.

What to include in your impact report 

  • Progress against all relevant measures of the company’s social and environmental performance and a summary of stakeholder engagement processes 

  • What concrete actions the company has taken 

  • The management strategies the company is using to achieve its social and environmental goals and its progress towards them
