Four out of the six presidential candidates have ruled out using election posters.

A spokesperson for Sinn Féin's candidate Liadh Ní Riada said they had printed 17,000 posters, many of which have already been erected, but said all posters and cable ties will be removed after polling day and the posters will be recycled.

The campaign of President Michael D Higgins has printed 5,000 posters in Irish and English, around a quarter of those used in the 2011 campaign.

A spokesman said both the posters and cable ties were fully recyclable.

Seán Gallagher said posters were a blight on the landscape, while Gavin Duffy said they contribute to litter and were damaging to the environment.

A spokesperson for Senator Joan Freeman said she did not approve of the visual and physical damage posters do for towns and cities, while Peter Casey said he was opposed to posters and believes their day was long gone.

RTÉ's News at One asked all the candidates whether they would be using posters, here are the full responses:

Peter Casey:

Peter Casey says he is very opposed to posters, especially posters which are not biodegradable and no posters are being put up at all as he does not believe they work in a presidential campaign. He believes the day of the posters is long gone and people do not want them and are not influenced by them.

He says he is not a fan of single-use plastics, describing them as a curse, and he says we now have the technology to make starch based plastics, which although expensive are better for the environment.

Gavin Duffy:

Gavin Duffy is not using posters. He believes they contribute to litter, are damaging to the environment and unsightly and also pose risk to cyclists and pedestrians by obscuring views. They can also be dislodged during bad weather and high winds.

Joan Freeman:

Joan Freeman's campaign manager, Richard Mulcahy said: "On behalf of Senator Freeman I wish to state for the record that we will not be putting up posters anywhere for the Presidential Election. We do not approve of the visual and physical damage that posters do for towns and cities, and we feel that the benefits of not using posters to the environment far outweigh the short-term political gain of using them."

Seán Gallagher:

In the 2011 presidential campaign, Seán Gallagher said he would not be using election posters. At the time others spent approximately €500,000 on election posters.

He believes election posters are a blight on the landscape and has heard clearly the views of Tidy Towns groups about the damage caused by plastics and election posters and will not be using them in this campaign.

Micheal D Higgins:

The campaign has printed 5,000 Irish- and English-language campaign posters, approximately one-quarter of the number used in his 2011 campaign, and these are now being rolled out in locations across the country.

A spokesperson said both the posters and their cable-ties are fully recyclable, and the campaign has contracted for both posters and cable-ties to be removed and delivered to recycling centres at the end of the campaign.

The campaign forwards any correspondence received from Tidy Towns or local councils to the contractors, who have noted, and are following, any local rules and guidelines that may be in place.

Anyone with concerns or comments about the placement of the campaign posters can contact

Liadh Ní Riada:

We believe in the continued effectiveness of election posters as part of the democratic process. We have printed in the region of 17,000 posters, many of which have already been erected.

Where requested, we have co-operated with designated poster-free environments in villages and towns 

A spokesperson for her campaign said: "We wish to see an end to the use of single use plastics. All posters and cable ties used in the Liadh for President campaign will be removed after polling day. These posters will be recycled."
