Electric Vehicles
how can governments be advocating for electric cars when electric bikes use significantly less energy and materials than electric cars? This does not seem to be equitable for all the people on the planet.
It is true that electric bikes have a much lower environmental impact than electric cars in terms of energy and materials use, as well as land use and emissions associated with production and disposal. However, it is important to note that different transportation modes serve different needs and purposes, and electric cars may be more suitable for some contexts than electric bikes.
Governments may be advocating for electric cars as a way to reduce carbon emissions from the transportation sector, which is a major contributor to global greenhouse gas emissions. In many countries, the transportation sector is responsible for a significant portion of carbon emissions, and switching to electric vehicles, including cars and buses, can be an effective way to reduce these emissions.
Furthermore, electric cars may be more suitable for longer distances or for transporting larger groups of people, such as families. Electric bikes may be more suitable for shorter distances or for individuals who do not require a car for daily transportation.
It is also worth noting that promoting the use of electric vehicles, including bikes and cars, is just one part of a larger strategy to reduce carbon emissions and mitigate climate change. Governments may also be promoting other measures, such as public transportation, cycling infrastructure, and walking, as part of a comprehensive approach to reducing emissions and promoting sustainable transportation.
Ultimately, the choice between electric bikes and electric cars will depend on a variety of factors, including personal preferences, transportation needs, and local infrastructure. Governments can play a role in promoting both options and creating a more equitable and sustainable transportation system for all people on the planet.
however if we are not meeting the requirements to keep GHG emissions to less than 1.5 degC then how can we still be advocating for electric cars?
It is true that switching to electric cars alone may not be enough to keep global warming below 1.5 degrees Celsius, especially if the electricity used to charge the vehicles comes from fossil fuel sources. However, promoting the use of electric cars can still be an important part of a larger strategy to reduce carbon emissions from the transportation sector.
To achieve the goals of the Paris Agreement and keep global warming below 1.5 degrees Celsius, it will be necessary to implement a comprehensive approach that includes reducing energy consumption, increasing energy efficiency, promoting renewable energy, and transforming transportation systems.
This may involve a combination of measures, such as promoting public transportation, cycling and walking infrastructure, and shared mobility services, as well as encouraging the use of electric cars and trucks powered by renewable energy. In addition, it will be important to reduce the overall demand for transportation by promoting more sustainable land use patterns, such as compact, walkable communities and mixed-use developments.
Ultimately, the goal is to create a sustainable transportation system that meets the mobility needs of people while minimizing the environmental impact. This will require a comprehensive and integrated approach that goes beyond the promotion of electric cars alone, and takes into account the full lifecycle impacts of different transportation options.
we can meeting the 1.5 degC GHG emissions target of the Paris accord by 2030. Consider walking, cycling, public transport, electric bikes, electric cars, trucks, trains
The specific proportions and amounts of emissions for different transport sectors in a world where we can meet the 1.5°C GHG emissions target of the Paris accord by 2030 will depend on a number of factors, including regional differences in transportation modes, energy sources, and land use patterns.
However, according to estimates from the International Energy Agency, the transport sector is responsible for around 24% of global energy-related CO2 emissions. This includes emissions from all modes of transportation, such as cars, trucks, buses, trains, ships, and airplanes.
To meet the 1.5°C target, it will be necessary to significantly reduce the carbon intensity of transportation fuels, promote the use of low-carbon transportation modes, and reduce the overall demand for transportation through more sustainable land use patterns.
Some potential ways to achieve these goals include:
Promoting walking and cycling infrastructure to encourage more active forms of transportation. Expanding public transportation systems, particularly in urban areas, and encouraging greater use of buses, trains, and other mass transit options. Encouraging the use of electric bikes and electric cars, particularly those powered by renewable energy sources.
Promoting the use of more fuel-efficient vehicles, particularly for trucks and other heavy-duty vehicles. Encouraging more sustainable land use patterns, such as compact, walkable communities and mixed-use developments, to reduce the overall demand for transportation.
The exact proportion and amount of emissions reductions from each of these strategies will depend on a range of factors, including regional differences in transportation patterns and energy sources. However, taken together, these approaches can help to significantly reduce the carbon footprint of the transportation sector and help to meet the 1.5°C target of the Paris accord.
Each year how can we tell if we are on target to keeping global warming to less than 1.5 degC? What measures should be used?
To determine whether we are on target to keeping global warming to less than 1.5 degC, we need to monitor the concentration of greenhouse gases (GHGs) in the atmosphere and the Earth's temperature. One of the main indicators used to track GHG concentration is the atmospheric concentration of carbon dioxide (CO2), which is currently measured at the Mauna Loa Observatory in Hawaii.
In addition to tracking GHG concentration, we can also track emissions of GHGs to assess our progress. The United Nations Framework Convention on Climate Change (UNFCCC) requires countries to submit regular reports on their GHG emissions, which are then compiled into a global inventory.
To keep global warming to less than 1.5 degC, we need to limit the amount of GHG emissions to a level that is consistent with that goal. This means that we need to track our progress in reducing GHG emissions from all sectors, including energy, transportation, industry, agriculture, and forestry. The most commonly used measure for tracking emissions is CO2-equivalent emissions, which takes into account the different warming potentials of different GHGs.
Finally, we can also track our progress in implementing policies and measures to reduce GHG emissions, such as renewable energy targets, carbon pricing, and energy efficiency standards. These measures can help to accelerate the transition to a low-carbon economy and help us to stay on track to meeting our climate goals.
why is society not doing enough to keep GHG emissions to less than 1.5degC?
There are many reasons why society may not be doing enough to keep GHG emissions to less than 1.5°C, despite widespread recognition of the urgent need to address climate change. Some of these reasons include:
Lack of political will: Governments around the world may not be taking strong enough action on climate change, due to various factors such as competing priorities, short-term economic interests, and pressure from powerful interest groups.
Lack of public awareness: Many people may not fully understand the severity and urgency of the climate crisis, or may not be aware of the most effective ways to reduce their own emissions.
Economic barriers: Transitioning to a low-carbon economy requires significant investments in new technologies and infrastructure, which can be expensive and challenging to finance.
Social and cultural norms: There may be cultural and social barriers to adopting low-carbon lifestyles, such as the perceived need for car ownership or air travel.
Limited technological solutions: Some sectors of the economy, such as heavy industry and aviation, currently have few viable low-carbon alternatives. International coordination challenges: Addressing climate change requires coordinated action at a global level, which can be difficult to achieve due to competing interests and priorities among different countries.
Addressing these challenges will require a coordinated effort across all sectors of society, including governments, businesses, civil society organizations, and individuals. It will require ambitious policy and investment decisions, as well as changes in individual behaviors and social norms.
Electric cars use 100 times more resources than an electric bike. On a finite planet with limited resources how can we justify investing in electric cars for rich people when poor people have limited transport options. This does not seem morally or ethically fair.
It is important to consider both the environmental impact and social equity when making decisions about transportation options. While it is true that electric cars require more resources than electric bikes, there are other factors to consider.
For example, electric cars may be more suitable for people who live in areas with limited public transportation options or for those who need to travel long distances regularly. In addition, electric cars may be more accessible to people with disabilities or those who require specific accommodations in their transportation.
Furthermore, it is possible to prioritize investments in both electric cars and electric bikes as part of a comprehensive strategy to reduce greenhouse gas emissions from the transportation sector. Governments can work to ensure that electric cars are affordable and accessible to all, while also investing in infrastructure to support the use of electric bikes and other sustainable transportation options.
Ultimately, it is important to strike a balance between environmental concerns and social equity when making decisions about transportation options.
How can we boost investment in public transport? How can we reduce private car ownership and make transport more equiable?
Boosting investment in public transport and reducing private car ownership can be achieved through a combination of policy measures, infrastructure improvements, and social and cultural changes. Here are some potential strategies:
Improve public transport infrastructure: Investing in public transport infrastructure can make it more efficient, reliable, and accessible. This can include building new bus or rail lines, improving existing transit stops, and implementing smart transportation technologies like real-time vehicle tracking and automated fare collection.
Provide incentives for public transit use: Governments can provide incentives for public transit use, such as discounted fares, tax credits, or subsidies for low-income riders. Employers can also offer transit benefits to their employees, such as pre-tax transit passes or subsidies.
Implement congestion pricing: Congestion pricing involves charging drivers a fee for driving in congested areas during peak hours. This can help reduce the number of cars on the road and encourage the use of public transit.
Develop walkable and bike-friendly communities: Creating walkable and bike-friendly communities can encourage people to use active transportation options instead of cars. This can be achieved through infrastructure improvements such as bike lanes, sidewalks, and pedestrian crossings, as well as policies that prioritize active transportation.
Encourage car-sharing and carpooling: Car-sharing and carpooling can reduce the number of cars on the road and make transportation more affordable and accessible for everyone. Governments can provide incentives for car-sharing and carpooling, such as discounted tolls or dedicated carpool lanes.
Promote electric vehicles: Electric vehicles can help reduce greenhouse gas emissions from the transportation sector. Governments can provide incentives for electric vehicle ownership, such as tax credits or rebates, and invest in electric vehicle charging infrastructure.
Educate the public: Educating the public about the benefits of public transportation and the environmental and social impacts of car ownership can help shift attitudes and behaviors towards more sustainable transportation options.
By implementing these strategies, we can work towards a more equitable and sustainable transportation system that benefits everyone.
Businesses can play a significant role in encouraging sustainable transport options and reducing GHG emissions related to transport. Here are some steps that businesses can take:
Provide incentives: Companies can offer incentives such as subsidies, discounts or free parking to employees who use sustainable transport options such as public transport, carpooling, walking or cycling.
Promote telecommuting: Businesses can offer flexible work arrangements such as telecommuting, which can reduce the number of employees commuting to the office and therefore reduce GHG emissions related to transport.
Encourage cycling: Businesses can provide on-site facilities such as bike racks, showers and changing rooms to encourage cycling to work. Some companies also offer bike-sharing programs for employees.
Green logistics: Companies can switch to more sustainable logistics methods such as electric vehicles, cargo bikes or public transport for deliveries and transportation of goods.
Eco-driving: Companies can promote eco-driving techniques to their employees, such as reducing speed, avoiding aggressive acceleration and braking, and maintaining proper tire pressure, which can reduce fuel consumption and GHG emissions.
Public advocacy: Companies can lobby governments to invest in sustainable transport infrastructure and policies, such as bike lanes, public transport subsidies and congestion pricing.
Overall, businesses can have a significant impact on reducing GHG emissions related to transport by encouraging sustainable transport options and investing in more sustainable logistics methods.
How can schools and students transition to low carbon transport? What transport options could students adopt in travelling more independently to and from school?
Schools and students can transition to low carbon transport by adopting sustainable modes of transportation. Some of the options that students could consider in travelling more independently to and from school include:
Walking: If the school is close enough to home, students could walk to and from school. This is a great way to reduce carbon emissions and stay active. Cycling: Cycling is another great option for students who live a bit further away from school. Cycling is a low-carbon form of transportation that also promotes physical activity.
Public transport: Students can also use public transport such as buses or trains to get to school. This is a good option for students who live further away from school and don't have access to a bike. Carpooling: Students could consider carpooling with other students who live nearby. This can help to reduce the number of cars on the road and reduce carbon emissions.
Schools can also encourage the adoption of low carbon transport by:
Providing secure bike parking facilities for students who cycle to school. Working with local authorities to improve public transport infrastructure to make it more accessible and reliable. Encouraging and promoting carpooling initiatives amongst students. Offering incentives for students who choose to walk, cycle, or use public transport, such as free bus passes or reduced-price bike rentals. Incorporating lessons on sustainable transport into the school curriculum to raise awareness and encourage behaviour change amongst students.
90% of new electric vehicle sales in Australia are e-bikes and e-scooters. What does this tell us about what electric vehicle infrastructure is required in communities?
The fact that 90% of new electric vehicle sales in Australia are e-bikes and e-scooters indicates that there is a growing demand for smaller, more efficient and affordable electric vehicles. This suggests that communities should invest in infrastructure that supports the use of such vehicles, such as bike lanes, bike racks, and charging stations for e-bikes and e-scooters.
Additionally, it may be useful to provide education and incentives for people to switch to these more sustainable forms of transport. For example, schools and workplaces could provide bike parking and shower facilities to encourage cycling as a means of transportation. Local governments could also offer subsidies or tax credits to individuals who purchase electric bikes or e-scooters, making them more accessible and affordable. Overall, communities should prioritize infrastructure and policies that support the use of low-carbon, sustainable modes of transportation.
how can we easily communicate the amount of resources and environmental pollution that is associated with an electric car versus an electric bike?
One way to communicate the differences in resources and environmental pollution associated with electric cars versus electric bikes is to use infographics or comparison charts. These can visually represent the data and highlight the significant differences between the two modes of transportation.
Another way is to use simple, straightforward language to explain the differences in terms of energy and materials required for each option. For example, you could explain that electric cars require much larger batteries and more resources for production and charging infrastructure than electric bikes. Additionally, you could highlight the benefits of using electric bikes, such as their low carbon footprint, lower cost, and health benefits from physical activity.
It may also be helpful to provide real-world examples and case studies that illustrate the environmental impact of each option. This can help people understand the impact of their choices and make more informed decisions about their transportation.
if the world cannot meet the 1.5degC emissions target then how can we keep on investing in resource intensive and environmentally destructive electric cars when there are more environmentally sustainable and lower emitting alternatives available?
It is important to note that the transition to electric cars is not solely based on reducing GHG emissions, but also on reducing air pollution and promoting energy security. While electric cars do require more resources to produce than electric bikes, they still emit less GHG emissions per kilometer traveled than gasoline-powered cars. Additionally, the development of electric cars and associated infrastructure can drive innovation, technological advancement, and job creation in the renewable energy sector.
However, it is important to consider the trade-offs and externalities associated with any type of transportation. It is essential to invest in sustainable and equitable transportation options, such as public transportation, biking, and walking, in addition to electric cars and other personal vehicles. A holistic approach that considers the entire life cycle of the transportation system, including the environmental impact of resource extraction, manufacturing, use, and disposal, can help guide decisions and policies towards a more sustainable future.
yes - but if there is a carbon budget for transport and we need to stay within that carbon budget what would the mix of sustainable transport options look like and can we assign carbon budgets to each mode of transport?
Yes, it is possible to assign carbon budgets to each mode of transport and strive for a mix of sustainable transport options that can help stay within the carbon budget for transport.
Here is an example of a breakdown of carbon budgets for different modes of transport based on the Global Carbon Project:
Walking: 0 gCO2/km Cycling: 5 gCO2/km Public transport (bus, tram, metro, train): 50 gCO2/km Electric bikes: 22 gCO2/km Electric cars (depending on the source of electricity): 70-170 gCO2/km Petrol cars: 170-250 gCO2/km Diesel cars: 170-270 gCO2/km Domestic flights: 250 gCO2/km International flights: 190 gCO2/km Based on this breakdown, it is clear that walking, cycling, and public transport have the lowest carbon footprint, while electric cars and electric bikes are more carbon-friendly than petrol and diesel cars.
To achieve the 1.5degC emissions target, a mix of sustainable transport options would be required, including promoting walking, cycling, and public transport, as well as encouraging the use of electric bikes, electric cars, and alternative modes of transport such as carpooling and ride-sharing. This would require a shift in attitudes and behaviours towards more sustainable and low-carbon forms of transport, as well as government policies and initiatives to support and incentivize the adoption of these modes of transport.
For each mode of transport, can we assign yearly carbon emission budgets and yearly targets in order to stay within 1.5 degC planetary warming window? What would that look like over the next 10 years?
Yes, we can assign yearly carbon emission budgets and targets for each mode of transport to stay within the 1.5°C planetary warming window. However, the specific targets and budgets would depend on a range of factors, including the current emissions from each mode of transport, the available low-carbon alternatives, and the capacity of different sectors to reduce emissions.
To give a general idea, some estimates suggest that in order to limit warming to 1.5°C, transport emissions need to be reduced by at least 50% by 2030 and reach net-zero by around 2050. To achieve these goals, different modes of transport would need to have different annual emissions targets and budgets based on their respective emissions profiles, potential for decarbonization, and other relevant factors.
For example, electric cars could have a relatively high annual carbon budget compared to petrol or diesel cars, as they emit less carbon dioxide. In contrast, aviation may need to have a much lower carbon budget and annual emissions target due to the high emissions associated with air travel. Walking, cycling, and public transport would ideally have a very low carbon budget, as they emit very little or no carbon emissions.
The specific targets and budgets would need to be developed through a comprehensive and collaborative process involving government, industry, and civil society. This would require a deep understanding of the emissions profiles of different modes of transport, as well as a range of other factors, including technological progress, infrastructure investments, and behavioural change.
Should a carbon budget for transport be assigned to households? Could this help households track their GHG emissions associated with different modes of transport?
Assigning a carbon budget for transport to households could be a helpful tool for tracking GHG emissions associated with different modes of transport. It could encourage households to make more sustainable transport choices and provide a framework for setting and achieving emissions reduction goals. However, the effectiveness of such a policy would depend on a range of factors, including the size of the carbon budget assigned to each household, the availability and accessibility of sustainable transport options, and the ability of households to afford or access low-carbon alternatives. Implementing a policy like this would also require a robust monitoring and reporting system to accurately track emissions and ensure that households are staying within their carbon budgets.
If everyone swapped their car for an electric bike of the next 5 years in Australia, by how much would this reduce GHG emissions in the transport sector and what other ramifications would this have for the transport sector?
Swapping cars for electric bikes can have a significant impact on GHG emissions in the transport sector. According to a study by the European Cyclists' Federation, replacing car trips with bicycle trips can result in emissions reductions of up to 50% for urban travel.
In the case of Australia, the transportation sector was responsible for around 102 MtCO2e (million tonnes of CO2 equivalent) of emissions in 2019, which is about 18% of the country's total emissions. Assuming that each car is driven around 13,000 km per year and emits around 4.6 tonnes of CO2e per year, if all cars in Australia were replaced with electric bikes, it would save around 73 MtCO2e per year. This is a significant reduction in emissions and would make a meaningful contribution to achieving the 1.5 degC target.
However, there would also be other ramifications for the transport sector, such as changes in infrastructure, changes in travel behavior, and changes in the types of goods and services that are transported. There would likely be a shift in the demand for different types of infrastructure, such as bike lanes and secure bike parking facilities. Additionally, it is possible that there would be changes in travel behavior, such as shorter trips and more frequent trips, due to the ease of using an electric bike. Finally, there would be changes in the types of goods and services that are transported, as some goods and services may be better suited to electric bikes than others.
If we swapped cars for electric bikes would society travel less and be more local?
It's difficult to say for certain, as it depends on a variety of factors such as personal habits, infrastructure, and culture. However, it is possible that society may become more localized if there is a shift from cars to electric bikes. This is because electric bikes have a shorter range and can be less convenient for long-distance travel, which could encourage people to stay closer to home. Additionally, electric bikes are typically slower than cars, which could make short-distance travel more appealing and encourage people to choose destinations that are closer to their homes. However, it's important to note that this is a complex issue with many variables, and it's impossible to predict exactly how such a shift would play out.
In a society that has low GHG emissions and keeps global warming to less than 1.5degC and also lives with the Earth's planetary boundaries - would it be better if we stayed more local and travelled fewer kilometers per year?
In a society that stays within the Earth's planetary boundaries and keeps global warming to less than 1.5 degrees Celsius, it would be better to prioritize more sustainable modes of transportation such as walking, cycling, and public transport that have lower GHG emissions and lower resource demands than private cars. Staying more local and reducing travel distances where possible can also help to reduce the carbon footprint of transportation. However, it is important to note that access to mobility is important for social and economic reasons, and finding a balance between sustainability and mobility needs is crucial. Additionally, reducing the carbon footprint of transportation is just one part of the broader efforts needed to achieve a sustainable and equitable society.
Yes - but we are currently exceeding some of the Earth's planetary boundaries. Don't we have to act with a greater sense of urgency and make greater reductions in emissions right now?
Yes, that is correct. We are already exceeding some of the Earth's planetary boundaries and the impacts of climate change are becoming increasingly apparent. Urgent action is needed to reduce greenhouse gas emissions and prevent further damage to the planet. While it is important to consider the potential benefits of local and sustainable transport options, we must also focus on rapidly reducing emissions in all sectors to keep global warming to less than 1.5 degrees Celsius and prevent further ecological damage.
