With its complex system of highways, railroads, ports, airports, and public transit systems, New Haven County's transportation network is unique, considering its size. Transportation is the most significant sector contributing to GHG emissions in the state and the county, with cars and light trucks being primary contributors. In contrast, public transport only accounts for 0.24% of the emissions from this sector.  People in New Haven-Milford, CT, have an average commute of 25.6 minutes (New Haven County, CT | Data USA, n.d.) and around 80% of the employed population drives alone to work. Car ownership in New Haven-Milford, CT, is approximately the same as the national average, with an average of 2 cars per household (New Haven County, CT | Data USA, n.d.). Much like the rest of the State, New Haven County's emissions from diesel vehicles are around 30% higher than those from gasoline vehicles.  Although New Haven County's transportation emission ranks lower than other metropolitan statistical areas within Connecticut, reducing the sector's emissions remains a priority with added concern for equitable public mobility.  

Car ownership is generally high but Electric Vehicles make up less than 2% of the total vehicles (Martinez, 2023). In 2022, the number of Electric Vehicles in Connecticut went up to 35,100. In 2021, approximately 78,000 EVs, plug-in hybrids, or hybrid vehicles were registered in Connecticut. These numbers are an improvement from the years prior but infrastructure needs to support this growth; the State needs to create at least 1,500 more charging stations to meet the EV demand and target by 2025 (Martinez, 2023). Given this information and the high commute times, reducing vehicle miles travelled and increasing EV adoption are high priorities.  

Many residents in vulnerable communities lack adequate access to transportation. Around 14% of the population stated that they stayed home due to a lack of reliable transportation (Abraham, 2023). Car ownership varies based on race and ethnicity and by the number of workers in the home. 69% of Black households and 47% of Latino households that had no employed members did not own cars. Compared to this, only 33% of white households with no employed members lacked vehicle access (Abraham, 2023).  

Due to its industrial past, the kind of jobs available in some parts of the town are very limited and having access to a car is needed to find and keep a job. This is also because less than 40% of the population lives in transit walksheds and some towns have no transit connection to urban cores where employers are concentrated. Broadband internet access also impacts the educational opportunities and employment opportunities available. Broadband access has improved in the past years, but it continues to vary by income. Although broadband access has increased over the past several years, it varies by income. Amongst households earning less than $50,000 per year, around 25% still do not have access to broadband internet (Abraham, 2023). Improving this access can also open opportunities for employment that does not require high commute times and reduce the overall dependence on cars and vehicle miles traveled in the county.
