350.org was founded in 2008 by a group of university friends along with author Bill McKibben, who wrote one of the first books on global warming for the general public, with the goal of building a global climate movement.
350PDX is a local group affiliated with 350.org (in other words, we’re friends), but we are a completely separate organization in that we make all of our own decisions, set our own campaign priorities and do all our own fundraising. We were founded in 2013.
The number 350 comes from the scientific safe upper limit of how many parts per million of carbon dioxide should be in the atmosphere (in other words, for every million particles of the oxygen, nitrogen, water vapor, etc. that make up air, a maximum of 350 particles should be carbon dioxide). Before the industrial revolution that number was roughly 270. We are currently at around 415, meaning we are overstepping this important planetary boundary and need to stop emitting greenhouse gases and bring that number back down to 350 or below as fast as possible.
350PDX is a non-discriminatory organization that seeks to support and empower all those working within a diverse and inclusive climate justice movement. For that reason we adhere to both the letter and the spirit of applicable laws that prohibit discrimination based on race, color, creed, religion, age, sex, gender identity, sexual orientation, marital status, national origin, citizenship status, veteran status, disability, or any other characteristic prohibited by law. We actively strive to create a space of equity and trust for all who wish to contribute to our goals and welcome those who can teach us how to do this better. Any concerns about misconduct are received and dealt with seriously.
