Cars’ Contribution to Greenhouse Gas Effects in Global Warming By City Tech Blogger Eric Qian

Cars’ Development of Global Warming and Rise of Electronic Vehicles to Reduce Gas Emissions

Cars have been around for a long time and have only increased in quantity and that increase also bumps up the amount of carbon emissions that they produce, nearly one-fifth of all US emissions. The US contributes to nearly 30% of all global US global warming emissions. Every gallon of gas emits around 24 pounds of global warming contributing gasses and the amount only increases in bulk as more cars are introduced into the market. Recently, General Motors (GM) announced its rededication to Electric Vehicles (EV) as well as its development of its new battery which would be priced at around $100 per kilowatt an hour; it will be on par with the cost of traditional gas vehicles. GM also claims that it will meet then improve on it with a new ultium battery system that is in development through a partnership with LG Chem; these batteries are claimed to be capable of going up to 400 miles on a single charge which is a little bit better than Tesla who is the current leader in the field.


However, GM has claimed to take the lead in Electronic Vehicles, but was  not able to deliver in the past. It was getting good reviews for its Volt and Bolt models, but were not able to sell whereas Tesla was able to deliver sales being an EV focused automaker and left everyone else in the dust. GM has a plan and they seem serious in achieving these goals. They want to be a part of a future where EV’s playing a major role in the consumer market. Due to the government rules and subsidies that encourage EV purchases in larger countries, such as China and Europe, GM sold 2.9 million vehicles in the US last year while its EVs sold a mere 16,418 units and the thought of selling millions of EVs would be a great improvement to the carbon emissions issue.


Reduction of Gas Emissions by EV’s Batteries

The change towards cleaner vehicles is very impactful for the rise in greenhouse gases and because vehicles play a large part in day-to-day lives by reducing the amount of greenhouse gases they produce, they can reduce emissions down the line. The change towards EVs already show results where in the UK emissions have dropped 38%, and are expected to fall more than 70% in the 2020s. Electronic cars are three times lower than conventional cars, and by going one step further because from already using renewable energy, the factories they use to produce the cars can also make the shift towards cleaner ways of production, such as for Tesla factories notable for the Nevada Gigafactory producing substantially lower emissions in production. The reduction of gas emissions initially is higher due to its batteries.  However, over time and usage of the emissions are much lower than conventional cars starting after less than four years of driving and produces far less in its lifetime. See progress report below for EV’s reduction of gas emissions over a period of time.

My Take on Climate Change

As disasters increase in both frequency and severity worldwide, many scientists had anticipated these events and provided evidence supporting the reality of climate change. Many of these disasters can, to a certain extent, be attributed to climate change.  I’ve observed compelling evidence, and I’m convinced that the dramatic


My Take on Climate Change

As a child, I didn’t fully understand the severity of climate change. However, now I realize that it’s a significant problem that poses a threat to our planet. Climate change refers to long-term changes in temperature and weather patterns that can be caused by natural factors. But since


My Take on Climate Change

Climate change has been responsible for affecting crops by the frequent change in temperature, increase in rainfall and more droughts. Note that climate is not the same as weather; weather is precipitation and temperature occurring at one single time, as climate occurs over a long period  of time.
