This plan proposes an objective to reduce Basque contribution to climate change and includes specific action, from different stakeholders (citizens, companies, administration). This challenge for reducing greenhouse gases emissions in the context of climate change is the main argument for the use of participatory systems. Collaborative work based in a transparent and effective communication process could be very useful and even necessary for an effective solution. In this context, www.stopco2euskadi.net is a regional initiative of the Basque Office on Climate Change, based on a e-participation system, that promotes and brings together the actions carried out by all the agents of the Basque Country, in order to reduce greenhouse gases causing climate change in the 2009-2012 period.Text/Conference Paper
