On 22 June 2021, the Deputy Minister for Climate Change, Lee Waters MS, announced that there would be a pause on all new road schemes while the existing pipeline of projects is reviewed.
The context for the review is that Welsh Government have declared a climate emergency with an aim of reducing CO2 emissions across the whole economy by 63% by 2030.
Net Zero Wales also intends to increase the proportion of trips by sustainable modes (public transport and active travel) to 35% by 2025 and 39% by 2030.
