Questions & Answers

Q: How much greenhouse gases do transportation vehicles release into the atmosphere each year?

Transportation vehicles release 8.2 billion tons of greenhouse gases annually, contributing to 16% of the total emissions.

Q: What are the two main sources of emissions in transportation?

The majority of emissions come from personal vehicles (cars, vans, motorcycles, SUVs), accounting for almost half of the total. The other half comes from cargo ships, semi-trucks, planes, buses, and other vehicles.

Q: How can decarbonizing transportation help address environmental injustices?

By reducing emissions from vehicles that pass through low-income communities, decarbonization can lower air and water pollution, which disproportionately affects these communities. This can lead to improved physical and mental health outcomes.

Q: What is the key step in tackling decarbonization?

The first step is to electrify vehicles, making them more sustainable. Additionally, making electric vehicles more efficient and incorporating alternative fuels will be crucial.

Summary & Key Takeaways

• Transportation is a major contributor to greenhouse gas emissions, accounting for 16% of the total emissions annually.

• Half of transportation emissions come from personal vehicles, while the other half is from cargo ships, semi-trucks, planes, and buses.

• Decarbonizing transportation not only helps mitigate climate change but also has the potential to address environmental injustices experienced by marginalized communities.
