Changes in Carolina transportation, from electric vehicles to ride sharing, could slow warming climate in SC NC

Around The Carolinas, revolutionary changes are under way in transportation. More electric vehicles like Teslas are on the road, people are taking advantage of sharing mobility services such as Uber and Lyft, and the rise in telework during the COVID-19 pandemic has shifted the way people think about commuting.

Transportation is a growing source of the global greenhouse gas emissions that are driving climate change, accounting for 23% of energy-related carbon dioxide emissions worldwide in 2019 and 29% of all greenhouse gas emissions in the U.S.

Scientists examined the latest research on efforts to mitigate climate change. The report concludes that falling costs for renewable energy and for electric vehicle batteries, in addition to policy changes, have slowed the growth of climate change in the past decade, but that deep, immediate cuts are necessary to stop emissions growth entirely and keep global warming in check.

All-electric vehicles have grown dramatically since the Tesla Roadster and Nissan Leaf arrived on the market a little over a decade ago, following the popularity of hybrids.

In 2021 alone, the sales of electric passenger vehicles, including plug-in hybrids, doubled worldwide to 6.6 million, about 9% of all car sales that year.

Strong regulatory policies have encouraged the production of electric vehicles, including California’s Zero Emission Vehicle regulation, which requires automakers to produce a certain number of zero-emission vehicles based on their total vehicles sold in California; the European Union’s CO2 emissions standards for new vehicles; and China’s New Energy Vehicle policy, all of which have helped push EV adoption to where we are today.

Beyond passenger vehicles, many micro-mobility options in The Carolinas region – such as scooters and bikes, as well as buses, are starting to become electrified. As the cost of lithium-ion batteries decreases, these transportation options will become increasingly affordable and further boost sales of battery-powered vehicles that traditionally have run on fossil fuels.

An important aspect to remember about electrifying the transportation system is that its ability to cut greenhouse gas emissions ultimately depends on how clean the electricity grid is. China, for example, is aiming for 20% of its vehicles to be electric by 2025, but its electric grid is still heavily reliant on coal.

Other areas of transportation are more challenging to electrify. Larger and heavier vehicles generally aren’t as conducive to electrification because the size and weight of the batteries needed rapidly becomes untenable.

For some heavy-duty trucks, ships and airplanes, alternative fuels such as hydrogen, advanced biofuels and synthetic fuels are being explored as replacements for fossil fuels. Most aren’t economically feasible yet, and substantial advances in the technology are still needed to ensure they are either low- or zero-carbon.

While new fuel and vehicle technologies are often highlighted as decarbonization solutions, behavioral and other systemic changes will also be needed to meet to cut greenhouse gas emissions dramatically from this sector. We are already in the midst of these changes.

Telecommuting in South Carolina, North Carolina

During the COVID-19 pandemic, the explosion of teleworking and video conferencing reduced travel, and, with it, emissions associated with commuting. While some of that will rebound, telework is likely to continue for many sectors of the economy.

Shared mobility in South Carolina, North Carolina

Some shared mobility options, like bike and scooter sharing programs, can get more people out of vehicles entirely.

Car-sharing in South Carolina, North Carolina

Car-sharing and on-demand services such as Uber and Lyft also have the potential to reduce emissions if they use high-efficiency or zero-emission vehicles, or if their services lean more toward car pooling, with each driver picking up multiple passengers. Unfortunately, there is substantial uncertainty about the impact of these services. They might also increase vehicle use and, with it, greenhouse gas emissions.

Making Charlotte a public transit-friendly city

Public transit-friendly cities: Another systemic change involves urban planning and design. Transportation in urban areas is responsible for approximately 8% of global carbon dioxide emissions.

Efficient city planning and land use can reduce travel demand and shift transportation modes, from cars to public transit, through strategies that avoid urban sprawl and disincentivize personal cars. These improvements not only decrease greenhouse gas emissions, but can decrease congestion, air pollution and noise, while improving the safety of transportation systems.

Much of the uncertainty in how much technological change and other systemic shifts in transportation affects global warming is related to the speed of transition.
