Dublin is to become the first Irish city to sign a commitment to bring air quality to safe levels by 2030.
All four local authorities in the county are joining the 'Breathe Life' campaign.
Deputy Lord Mayor of Dublin, Tom Brabazon, says hitting the targets will involve difficult and potentially unpopular decisions.
He's calling on Dubliners to be 'Climate Brave' in order to make the changes happen;
"The nuts and bolts of this haven't been worked out but it has been suggested things that could be done, one of them is that there could be low emission zones that would be created within the city. For example certain types of vehicles, such as electric vehicles, would be the only ones allowed in a particular zone."
The Mayor of Fingal, Eoghan O’ Brien, said: “We are seeing more of the impacts of climate change on our environment and the actions that are needed to tackle this crisis require the support of the entire community. We have already acted in Fingal to improve air quality with programs like the School Streets initiative which has already reduced carbon emissions outside of a primary school in Malahide."
By signing up to the campaign, Dublin will be joining 76 Cities, Regions, and Countries around the globe in demonstrating a commitment to bring air quality to safe levels.
According to the World Health Organisation 92% of people breathe air quality which falls short of the recommended guidelines, while there are 7 million deaths around the world every year from air pollution.
According to climate activist Beth Doherty, "Solving this crisis will require large, brave leaps, not just steps, towards concrete climate action as a city."
