The Scottish Government is investing £2 million in the country’s eco-friendly bus fleet in a bid to lower carbon emissions.Over the last three years the Scottish Green Bus Fund has allowed bus operators to purchase 94 low carbon buses, which are able to deliver 30% reductions in greenhouse gas emissions as compared with typical Euro III diesel buses, along with significant fuel savings.Around £2 million has been made available this financial year for the Green Bus Fund 4 which is expected to see a further 20-25 green buses on Scotland’s roads.Details will be published shortly with bus operators, local authorities and regional transport partnerships invited to submit applications for funding.Transport Minister Keith Brown (pictured) said: "The Scottish Green Bus Fund is helping our bus industry invest in the latest emission reducing technology and is another clear indication of our support and commitment to the bus industry in Scotland.“Low carbon transport benefits us all through an improved environment and a strong public transport network plays a part in this, as well as cutting congestion on the roads and making them safer for all users.”The Scottish Green Bus Fund aims to cut greenhouse gas emissions, improve air quality and accessibility and encourage modal shift. Feedback from the first round of the scheme shows substantial fuel savings and reduced emissions.
