The Planet-Positive Periods Toolkit is Here!

The Planet-Positive Periods Toolkit is Here!

Have you ever looked for an accessible, comprehensive source of information and research about the environmental impact of different kinds of menstrual products?

Planet-Positive Periods is the outcome of a new and powerful creative partnership between Aisle, Green Periods and PERIOD. We are thrilled with this new suite of up-to-the-minute research and resources about sustainability and menstruation, all in a free, open-source format available to anyone.

About the Planet-Positive Periods team

PERIOD. is a youth-fueled nonprofit that strives to eradicate period poverty and stigma through service, education, and advocacy. Through the distribution of menstrual products, promotion of youth leadership, and championing of menstrual equity in policy, PERIOD. aims to center those disproportionately affected by period poverty and support local efforts for menstrual equity.

Green Periods is a social impact project creating awareness about the economic and ecological implications of menstruation. With its unique menstrual footprint calculator, Green Periods is on a mission to create global awareness about reusable menstrual products that are good for your body, wallet and the planet, bridging the gap between menstruation, education, environment and technology.

Aisle (formerly Lunapads) has been leading the sustainable menstrual health and period equity movement since 1993. Our groundbreaking collection of cloth pads and period underwear was the first of its kind, and we have been steadfast in our championing of transparency, ethical manufacturing and business as a force for good, as embodied by our proud B Corp status.

Our collective vision was to create a suite of tools for students to take an intersectional deep dive into the sustainability ins and outs of period products, including using Green Period’s personal period ‘footprint’ calculator to quantify the impact of individual choices. How exactly do disposables and reusable products stack up, for example? And what steps can be taken to improve access to reusable period products for students and other groups who may not be able to easily afford them?

The Planet-Positive Periods toolkit includes:

  • Slide presentation
  • Facilitator’s Guide
  • Research Appendix
  • Assessment Quiz
  • Video webinar
  • Shareable Infographic

As with any thriving partnership, the whole is invariably bigger than the sum of the parts. Our collective drive, wisdom, creativity and deep commitment to sustainability, menstrual health and period equity have created a world-class, publicly accessible free resource that we believe will be a vital lever in moving the broader period equity movement forward.

Finally, one of the things that we feel proudest of is the quality of research that we were able to draw from. In recent years, there have been a host of new studies that help to paint a far more detailed portrait of the social and environmental impacts of period poverty, for example.
