Green transportation reduces greenhouse gas emissions

Greenhouse gas emissions from transportation account for about 28% of total US greenhouse gas emissions, making it the largest contributor to US emissions. Similarly, in China, the transportation sector accounts for about 10% of total CO2 emissions. The burning of fossil fuels like gasoline and diesel releases carbon dioxide, a greenhouse gas, into the atmosphere. The buildup of carbon dioxide and other greenhouse gases like methane, nitrous oxide, and hydrofluorocarbons is causing the Earth's atmosphere to warm, resulting in climate change.

Green transportation can play a crucial role in reducing greenhouse gas emissions and mitigating climate change. Public transportation, such as buses and trains, can lead to significant reductions in carbon emissions. For example, US public transportation saves 37 million metric tons of carbon dioxide annually, equivalent to the emissions from electricity generation for 4.9 million households. Locally, initiatives like the move from diesel to compressed natural gas (CNG) fuel have shown positive results. For instance, KCATA's switch to CNG reduced its greenhouse gas emissions by 1,870 metric tons, equivalent to taking 395 passenger cars off the road for a year.

Digital technologies also offer innovative options for promoting green transportation. Low-carbon-travel functions on digital maps can encourage users to choose more sustainable travel options. Additionally, digital tools can facilitate public participation in green mobility, helping to foster consensus and collaboration among government, social organizations, enterprises, and stakeholders.

Green transportation not only reduces greenhouse gas emissions but also offers multiple environmental and health benefits. Sustainable transportation options can decrease our dependence on foreign oil, save consumers money, and improve air quality. With better air quality, there can be fewer cases of respiratory ailments like asthma and even cancer. Additionally, green transportation can reduce noise pollution, making neighborhoods quieter and more pleasant for everyone.

Low-carbon fuels and vehicle technologies

The transportation sector is the leading contributor to greenhouse gas emissions in the US, with gasoline-powered cars and light trucks being the primary culprits. To address this issue, the transition to low-carbon fuels and vehicle technologies is essential.

Low-carbon fuels, such as compressed natural gas (CNG), biofuels, hydrogen, and electricity, produce fewer greenhouse gas emissions than traditional fuels like gasoline, diesel, and jet fuel. For example, the use of CNG fuel by RideKC buses has resulted in a reduction of 1,870 metric tons of greenhouse gas emissions, equivalent to taking 395 passenger cars off the road for a year. Additionally, US public transportation saves 37 million metric tons of carbon dioxide annually, showcasing the impact of adopting low-carbon fuels.

Low-carbon vehicle technologies include hybrid electric vehicles (HEVs), battery electric vehicles (BEVs), and fuel cell electric vehicles (FCEVs). HEVs combine an internal combustion engine (ICE) with an electric motor and battery, resulting in reduced fuel consumption and emissions. BEVs and FCEVs offer even greater environmental benefits, with FCEVs having the potential to repay their climate debt faster than BEVs. However, the adoption of these low-carbon technologies is influenced by various factors, including government regulations, consumer demand, technological progress, and economic considerations.

To facilitate the transition to low-carbon fuels and vehicle technologies, several strategies can be employed. These include implementing low-carbon fuel standards, investing in cleaner technologies, and providing incentives for the adoption of clean vehicle technologies and infrastructure. For instance, the SmartWay program by the EPA helps the freight transportation sector improve supply chain efficiency, reduce greenhouse gases, and save fuel costs. Additionally, the EPA provides resources like the Green Vehicle Guide to help consumers choose vehicles that reduce transportation-related emissions.

In conclusion, the adoption of low-carbon fuels and vehicle technologies is crucial in mitigating the environmental impact of the transportation sector. By implementing policies, investing in research and development, and encouraging the use of sustainable alternatives, we can significantly reduce greenhouse gas emissions and work towards a greener future.

Strategies to reduce vehicle miles travelled

Green transportation has a significant impact on air pollution, and strategies to reduce vehicle miles travelled (VMT) are an important part of improving air quality.

One strategy is to encourage the use of public transportation, which has been shown to reduce greenhouse gas emissions significantly. For example, public transportation in the US saves 37 million metric tons of carbon dioxide annually, equivalent to the emissions from the electricity used by nearly 5 million households. Moving from diesel to compressed natural gas (CNG) fuel also has benefits, as demonstrated by the KCATA public transportation provider, which reduced its greenhouse gas emissions by 1,870 metric tons by switching fuels.

Another strategy is to reduce the reliance on single-occupancy vehicles. This can be achieved by encouraging active transportation such as walking and cycling, and by improving the infrastructure for these modes of transport. Building protected bike lanes, sidewalks, and bus shelters, increasing the reliability of transit, lowering fares, and slowing down traffic in residential areas can all help to achieve this.

The creation of 15-minute cities, where all basic needs are located within a 15-minute reach, is another strategy to reduce VMT. This reduces the need to travel long distances, and can be supported by better land use and transportation practices.

Additionally, the implementation of pricing strategies, infill development, transportation investments, and travel demand management programs can also help to reduce VMT. For example, California's Global Warming Solutions Act of 2006 (Assembly Bill 32) aims to reduce greenhouse gas emissions in the state to 80% below 1990 levels by 2050, and the state has a direct role in implementing pricing strategies to achieve this.

Finally, improving the efficiency of the freight transportation sector and reducing fuel consumption in the transportation industry as a whole can contribute to reducing VMT and improving air quality.

Public transit systems save energy

Greenhouse gas emissions from transportation account for about 28% of total US greenhouse gas emissions, making transportation the largest contributor to US GHG emissions. In this context, public transit systems are an effective way to conserve energy and reduce emissions.

Public transportation use saves the US the equivalent of 4.2 billion gallons of gasoline annually and more than 11 million gallons of gasoline per day. This is because public transportation has a proven record of reducing congestion. For example, in 2011, US public transportation use saved 865 million hours in travel time. Without public transportation, congestion costs in 2011 would have risen by nearly $21 billion from $121 billion to $142 billion in 498 urban areas.

Public transportation also reduces the number of vehicles on the road, which leads to a direct reduction in emissions. A single person who switches from a 20-mile solo commute by car to existing public transportation can reduce their annual CO2 emissions by 20 pounds per day, or more than 48,000 pounds in a year. This is equal to a 10% reduction in all greenhouse gases produced by a typical two-adult, two-car household. By eliminating one car and taking public transportation instead of driving, a savings of 30% of carbon dioxide emissions can be realized.

Additionally, public transit systems can help to improve air quality by reducing the use of fossil fuels such as gasoline and diesel, which release carbon dioxide and other greenhouse gases into the atmosphere. Improved air quality can lead to fewer cases of respiratory ailments such as asthma and even cancer. Furthermore, public transportation can help to reduce noise pollution, as less driving will make neighbourhoods quieter.
