Blog Action Day is an annual event that unites the world's bloggers in posting about the same issue on the same day on their own blogs with the aim of sparking discussion around an issue of global importance.

First and last, the purpose of Blog Action Day is to create a discussion. Bloggers are asked to take a single day out of their schedule and focus it on an important issue. By doing so on the same day, the blogging community effectively changes the conversation on the Web and focuses audiences around the globe on that issue. Out of this discussion naturally flow ideas, advice, plans, and action.

In 2007 on the theme of the Environment, we saw bloggers running environmental experiments, detailing innovative ideas on creating sustainable practices, and focusing their audience's attention on organizations and companies promoting green agendas.

In 2008 on the theme of Poverty, similarly focused the blogging community's energies around discussing the wide breadth of the issue from many perspectives and identifying innovative and unexpected solutions.

This year we aim to do the same for Climate Change, an issue that touches us all. Blog Action Day 2009 will be held on October 15 and is expected to be the largest-ever social change event on the Web. One day. One issue. Thousands of voices.

Why Climate Change?

Given the urgency of the issue of climate change and the upcoming international climate negotiations in Copenhagen this December, we think the blogosphere has the unique opportunity to mobilize millions of people around expressing support for finding a sustainable solution to the climate crisis.

About Blog Action Day

Blog Action Day was founded by Collis & Cyan Ta'eed in the summer of 2007.

With the support of their team at Envato in Australia as well as numerous volunteers, they recruited over 20,000 bloggers to write about the issue of Environment on October 15, 2007 - making the first Blog Action Day an immediate and quite unexpected success. In 2009, Collis & Cyan asked the team at, the world's leading blog network for social issues, to take over responsibility of Blog Action Day and expand its reach.
