The Scottish Greens have said they hope the "end is in sight" in their long-running campaign to ban fracking.

The Scottish Government introduced a moratorium barring the gas extraction technique in January 2015, but ministers have still to decide if this should be made permanent.

In their legislative programme for the coming year, announced last week, the government said they would set out their view on fracking and seek parliamentary approval "in the coming weeks" and a decision is expected before the end of the year.

Green MSP Alison Johnstone first proposed a ban on unconventional oil and gas extraction in 2014, bringing it to a vote in the Holyrood chamber where all other parties voted against it.

Labour and the Liberal Democrats have since changed their views to oppose fracking.

A 2016 report for the Scottish Government found fracking would be likely to cause a number of environmental hazards and could pose a risk to workers' health.

Ms Johnstone said: "Greens have opposed fracking from the start, and over the years I've been encouraged by the strength of feeling at community events I've taken part in right across Scotland.

"It's been a long struggle but we've stood together against the threat of this dangerous and unnecessary drilling process, and we hope the end is in sight.

"Given the risks to public health, the safety of workers, and the damage to our reputation as a climate change leader, it's high time the Scottish Government made the right decision and ruled out fracking for good."

A Scottish Government spokeswoman said: "Ministers will consider the evidence, including the results of the consultation, and will recommend a way forward before the end of this year."
