With the recent Volkswagen scandal changing how we think about transport and the environment, I asked the First Minister, Carywn Jones AM, what work the Welsh government has done to assess the reduction in carbon emissions that will arise from the South Wales Metro Project.
As a member of the Environment and Sustainability committee, I am committed to living within environmental limits and acting on climate change. I want to protect healthy eco-systems and create sustainable places for people to live.
The First Minister assured me that one of the priority outcomes for the Metro is to reduce carbon-dioxide equivalent emissions. By moving to modern and electric traction methods, carbon dioxide emissions will be reduced.
I wanted to know what detailed analysis the Government had done on the air quality benefits from reduced vehicle carbon emissions of each phase of the metro. The First Minister stated that in the first year of operation, electrification is estimated to deliver a reduction in carbon emissions from the rail vehicles of about 20%. In addition, 24% of carbon dioxide emissions in Cardiff is generated by road transport. The more people who shift from using cars to using rail and hybrid-buses, the more this percentage will decrease.
