Minister for the Environment Phil Hogan has said the newly-published Climate Change Bill will for the first time define Irish policy and legislation on climate change.

Mr Hogan said Government departments must now come forward with sectoral roadmaps in the areas of agriculture, energy, transport and the built environment to help progress policy.

He said in finalising the Bill, he had taken into account eight of the 13 recommendations from the Joint Oireachtas Committee on the Environment.

Mr Hogan told RTÉ's News at One that he does not believe domestic carbon targets are needed as Ireland is obliged to meet legally-binding EU targets on reducing carbon.

He said the country has made "a very robust case" at European Union-level about how to bring forward food production in a sustainable manner.

Mr Hogan said a cost-effective approach is needed to the "twin challenges" of sustainable food production and climate change in the agriculture and land use sector.

Negotiations are under way in Europe to ensure Ireland could go forward in this regard, he said.
