GLASGOW "must accelerate" its attempts to decarbonise as a new report lays out the "scale of the challenge" faced by the city as it bids to be net-zero by 2030.

The latest available figures show Glasgow produces 2.69m tonnes of carbon dioxide per year, with transport, domestic energy and power for industry and commerce the big generators of emissions.

But, working from baseline figures set in 2006, the amount of carbon released into the city's atmosphere each year has dropped by more than 1.5m tonnes, the most recent data, up to 2017, shows.

A report to be presented to councillors next week states this 37 per cent drop in emissions means Glasgow has exceeded its target of a 30 per cent reduction in CO2 production by 2020.

However, councillor Anna Richardson, city convener for sustainability and carbon reduction, believes, after the authority declared a climate emergency, work towards the 2030 net-zero target must speed up.

She said: "Glasgow is making very positive strides towards a sustainable future.

"But the difficulty is that the majority of carbon dioxide remains in the atmosphere for anything up to 200 years and so every year we are adding significantly to the issue of climate change.

"With Glasgow still producing 2.69m tonnes of carbon dioxide each year it shows the scale of the challenge we face as a city.

“We must accelerate the action we are taking to decarbonise our transport and energy use. "

Glasgow is the Scottish local authority with the third highest level of carbon emissions behind Falkirk and Fife, which have significant petroleum production operations.

Ms Richardson added: "There is a huge amount of work already underway to decarbonise Glasgow and the plans we put in place now are critical to the long term environmental and economic health of the city."

"Huge change lies ahead of us in the coming decade but we must remain focused on carbon neutrality going hand in hand with quality of life."

Work to decarbonise the city includes increasing renewable energy production such as electricity from solar panels, developing district heating systems, increasing the use of sustainable transport and supporting a shift to electric vehicles.
