Climate change experts say our carbon emissions are increasing after years of being in decline.
Ireland is set to miss the target to reduce emissions by 20% by 2020 - we are on track to only have reduced our emissions by 5%.
The Climate Change Advisory Council says we need to increase the use of renewable energy, make more homes energy efficient and use cleaner fuel if we're to be carbon free by 2050.
The Green Party has since called on the Government to phase out the sale of new petrol and diesel cars.
It comes after the British Government confirmed there will be no new combustion engines sold in the UK after 2040.
The deadline is part of the British government's plans to reduce air pollution and it is part of a scheme to get these vehicles off roads by 2050, with electric cars taking their place.
Green Party Leader deputy Eamon Ryan says people's concerns about electric cars are gradually being resolved.
"I think these are better cars. If you're going to stop people going from a to b, if we're going to tackle climate change we're going to have to have a better alternative, and this is a better alternative," he said.
