The Committee of the Regions plenary agreed in given the green light for a greener and more competitive transport sector by 2050. However, the CoR also added that these plans need more concrete interim targets and adequate funding. Also, the Committee supports the Commission's main goal of cutting greenhouse gas emissions in the transport sector by 60%, contrary to some national governments.

Mercedes Bresso, Committee of the Regions President, welcomed the concrete modal shift proposed in the transport white paper, from road to rail, inland waterway and maritime transports. Regional and local authorities have a key role to play in transport policy, for instance in maintaining the road network, managing public transport and enforcing air quality standards. She also underlined that the EU need greener and more efficient transports to tackle the challenge of global warming.

The most controversial Commission's proposal within the EU's Transport 2050 Strategy, to halve the use of ‘conventionally-fuelled’ cars in urban transport by 2030, phase them out in cities by 2050 and achieve essentially CO2-free logistics in major urban centres by 2030, was also endorsed by the CoR members. Furthermore, the CoR opinion insists that all "external" costs to transport, such as social costs, environmental pollution, noise and health hazards have to be factored into the price. According to the CoR, this has to happen by means of harmonised taxation across all modes of transport. All revenue generated from implementing EU legislation aimed at better integrating these external costs – for instance the 'Eurovignette' directive, which has recently been approved by the European Parliament – must be used for developing an integrated and efficient transport system.

The CoR proposes the provision of access to, and interoperability of, road traffic offence registers. Regional and local politicians share the Commission's "zero deaths" goal on road safety while recognising the many challenges it poses. This should make it possible to take infringements committed in other EU countries into account when applying sanctions. The Committee also welcomes the proposals on sustainable urban mobility plans, a key demand of earlier CoR opinions on the issue. However, the CoR expressed its disappointment that the Commission's 2014-2020 financial framework didn't introduce a new financial instrument for co-financing these mobility plans.
