To have A sustainable city such as Copenhagen Denmark which city has 55% wind-powered city. This is a big contributor to how sustainable they are. Even with wind power they still use coal which is 17% of the energy they use. Copenhagen has some of the best biking opportunities in the world with 45% of people commuting by bike. One of the corporate goals is to be 100% renewable energy by 2050. What are some ways you can reduce the carbon emissions in your city ( info from https://carbonneutralcities.org/cities/copenhagen/)

Some ways that people can reduce emission in their cities is by using public transportation as the cities in Europe have been shown to use. I personally use my cities public transportation called BART, which is a train that takes me from my house to San Ramon every weekend. If I were to take a car every weekend instead of BART then the emissions that just I would emit would be far greater then if I continued using the train. If everyone in my city used as much public transportation then the emissions would decrease a lot.

Do paper straws, that we get in almost every shop whit a drink, actually make a diffrance in the global carbon footprint? I am sceptical because we need to cut down a tree for them and after we use them, we cant reuse them like a plastic straw. Also they usualy come in a plastic pacaging so i dont see the point. At our homes there is a option to use metal straws but i dont like them because they are hard to clean and im not sure if they have better carbon footprint than plastic straws. Please tell me if you know a better alternative to plastic straws.

I know this doesn't seem helpful, but not using straw in general and sipping from a cup is probably the best solution that you'll ever find. One with zero waste and zero down side, unless you count something on your lip when you're drinking something a little more dense. Another solution though that I researched is pasta straws. I found a company named Pasta Life that makes straws made of pasta so you can just eat your straw right after which is also zero waste. The down fall was that you can't use it in hot beverages, but almost all hot beverages are better straight out of the cup anyway.

One way we can make a more sustainable city is first focusing on manageable things like  avoiding fast  fashion. Fast fashion is buying clothes that are currently in style, even if you don't need them, from companies that make them with cheap materials. This creates more clothes waste when these clothes go out of style fast and can cause harm to the environment because of the cheap and therefore more dangerous materials used in fast fashion. The creation of these clothes pollute the water and cause micro fabrics into the ocean as an article, "The Environmental Effect of Fast Fashion Explained" tells us. In order to prevent fast fashion, focus on thrift shopping, or buying higher quality clothes.

use more public transport  and increase car sharing.

I agree, but I suggest walking or biking instead of driving because burning fossil fuels release a large amount of carbon dioxide (CO2). If you're going somewhere far, then that's when it is suggested taking public transportation and carpooling. If you're planning on buying a car, then consider buying an electric one with cheaper models. Even though electric cars run on electricity produced from fossil fuels, they reduce the amount of air pollution as well as causing fewer greenhouse gas emissions.

I agree with both statements. I have seen that transportation is a big aspect of lots of peoples live. Now are walk and biking better then driving yes but so many people have to commute so far or there not safer paths for pedestrian to walk safely and that makes it hard to do those things. But we help by making public transportation but for many other and personal a lot of people don’t have public transportation access nearby. If there was a bus to my school that came even close to my house I would ride the bus but there is not. I think that as you continue to try and grow for a better sustainable city we can make a difference by making public transportation more accessible as a start.

Transportation plays a large role in our CO2 emissions. It's something many of us can't avoid and use daily, whether it's for school, work, extracurricular activities, or other purposes. So, how can we reduce the amount of CO2 being produced without just staying home and not going anywhere? As a society, we could try having more electric cars on the road, which can be an expensive option as it may require purchasing a vehicle. Some other less expensive ideas would include trying to carpool more, for example, when taking kids to school, or activities, for example, at the end of swim practice, picking up friends and taking them home, rather than their parents picking them up in another (less necessary) car. We could also start using public transportation, like the many Bishop O'Dowd students who take the AC transit and BART. Lastly, we could ask the city to implement more bike lanes, so that people feel more space when riding their bike from place to place.

In Oakland, the city where I live, I believe that the thing that contributed most to the average persons carbon footprint  was from their home. This means that we should be working on more ways to conserve energy, and find news ways to power things that are more sustainable. These can be achieved by increased use of turbines, solar panels, and wind mills. As of January 2023, an article titled Port of Oakland Utility Green Power Portfolio Grows says that "The Port of Oakland Utility serving customers at the seaport and airport fulfills 66.9% of its power needs from carbon free energy sources, nearly double the state average." This is just the start towards a more clean and sustainable future for Oakland and then the rest of the world.

I feel like I have a lot of everyday purchases especially food so if we all cut down on our everyday purchases like food or stuff that we don't need but want like toys or video games (physical copies) then our carbon emissions would go way down as well we would have more food to help out other countries that may be struggling with hunger and we would also have more toys to donate to struggling families.

I agree with the statement about buying food creating more carbon emissions, I tend to get takeout or drinks, which can be very wasteful. I think a way to fix this here at Bishop O'Dowd is to use sustainable packaging. The muffins and other pastries are wrapped in Saran Wrap, we could use paper bags instead. The pre-made lunches come in plastic containers, an easy fix to this is finding compostable to-go plates to use instead. This may cost more and take more effort, but I think if we could make it work here, then other schools would catch on and together make a difference. At O'Dowd, some differences have already been made, like paper forks and cups; we just need to take more steps towards a more sustainable school.

I emit way too much carbon from transportation every year and. I can help by taking public transportation more often because it helps reduce air pollution and lowers greenhouse gas emissions. Buses, trains, and subways use less fuel per person compared to cars, which means fewer harmful gases are released into the atmosphere. By choosing public transit, I can help decrease traffic congestion, save energy, and contribute to a cleaner, healthier environment.

I think we should have renewable energy because renewable energy is good because you can renew it. All members of the city should have access to Solar panels so we can thrive. We should also have easier transportation that relies of electric public transportation and bikes. The UN should also implement their 17 SDGs in local areas and promote, enforce these regulations.

For my city, Oakland, the highest contributor to the average person's carbon footprint is the home aspect. In our town, we should prioritize green energy like solar panels, wind turbines, etc. With help from the legislature and our government, we have the opportunity to change the way energy is consumed. The City of Oakland website tells us that Oakland ranks 5th in the 2024 Clean Energy Scorecard by ACEEE. This is a start towards total clean energy, which Oakland is working to achieve by 2045. I think all this information should become mainstream, and people from all places should have access to clean power.

A city that was a lot more controlling of the citizens carbon footprint would look very green. It would have so many trees and would have a lot of solar panels. I think that I would want to live there because of the cleaner air. I have bad lung problems, and having cleaner air would be amazing for my health.

Forcing people to pay fines if they go over a certain carbon limit would probably help. It wouldn't exactly control people but it would be a huge incentive for people to reduce their impact. Maybe getting some benefit if they go under an amount.

I agree with you, that would definitely be a great solution and also fines in some big cities would help. You can also go to the nearby mountains where the air is definitely cleaner than in your town. Being in nature will have a good effect on your health. Luckily I live in a place where the air is still clean and the water is also drinkable. I find it hard to believe that I have to buy bottled water every day. I can only imagine your situation.

I definitely agree with you, but I think that you're looking at the wrong problem here. The city doesn't really get much just from the carbon footprint of its citizens, instead, they should focus more on educating them about this problem. A lot of people don't even know what a carbon footprint is, let alone how much theirs is.
