Newsletter by Piotr Biernacki
Weekly observations from the world of sustainable development.
Piotr Biernacki
ESG Reporting Partner, Co-founder of MATERIALITY
I invite you to join me for a weekly dose of news, commentary, and advice on sustainable development.
In the Newsletter, I write about sustainable development management, reporting, and seizing opportunities. I highlight the most important trends visible in the activities of companies undergoing sustainable transformation, among investors, and in EU and global regulations.
You will find the latest issue of the Newsletter in your mailbox on Monday, and below are archived issues, which we publish a week after mailing.
Enjoy reading!
