Tourism leads the pack in growing carbon emissions

"The most net emissions were reported in aviation, utilities and private vehicle use for travel. Australia ranked in the top 20 countries that together contributed three quarters of the total tourism carbon footprint in 2019.">>

Drivers of global tourism carbon emissions

Five years of no flying
✈️ ❌ ➡️ 🚅 ✅

5 years ago, I realised that my #academic travels were emitting way too much #greenhouse #gas #GHG (up to 20 t #CO2 / yr) and hence that my #professional activity was not #sustainable. I thus decided to completely ban air #travel (#plane) and travel mainly by #train within #Europe.

5 years later (i.e. now), my professional travels' #carbonfootprint dropped by **a factor 50**, without impacting my #publication records (compared to 2017 - 2019).

I wrote a post for the #blog of @a4e about my experience. Check it out: astronomersforplanet.earth/fiv

Buying an electric car or electric vehicle in India

TL;DR is that in Bengaluru and rest of India it is not yet a good practical idea to buy an electric car without ensuring that a personal charger can be installed at home.

Dr. Katharine Hayhoe aptly speaks my mind here.

And most people don't have the resources or money to do what you do, because the system is skewed in the direction of maintaining our dependence on fossil fuels.
This is the case for electric cars or electric vehicles (EV), in India, at present. Though it may not be apple to apple comparison, from the same manufacturer, today an entry level crossover electric vehicle is costing approximately 50-60 percent more than a corresponding petrol vehicle with manual transmission.

The next interesting aspect is the operation and maintenance cost. According to a study
done here, the following conclusions are interesting considering an annual running of 18000 kilometres per year.
One will have to drive the EV for over 7.5 years to break even over the petrol, and almost 7 years over the diesel. What’s also worth mentioning here is that the EV’s battery has a warranty of 8 years, and could be expensive to replace.
Another study shows that the total ownership cost of a petrol vehicle, in India for first five years with a driving distance of 10,000 km per year, is approximately 30-35 percent less than an equivalent electric vehicle. The equations will change if cost of fuel continues to increase annually at a significant rate.

With respect to carbon emissions, when considering the whole life cycle, from manufacture to scrapping (and, hopefully, recycling), the following facts emerges according to an article titled "
Do electric cars really produce fewer carbon emissions than petrol or diesel vehicles?"
Lucien Mathieu, T&E’s cars director, said that even if you choose a worst-case scenario – vehicles made and driven with electricity largely from coal – the electric car will win out after about 70,000km (about six years of driving). “The more you drive an electric car, the better it gets,” he said.
The above is largely the scenario for India till now. As per an article, dated December 19 2023
India relies on coal for about 70% of its power generation and aims to add 17 gigawatts of coal-based power generation capacity in the next 16 months.
I accept that the economic sustainability of a petrol and electric car (electric vehicle), in India and other countries, will be determined by criteria such as usage frequency, trip distance, charging infrastructure availability. Full charging of an entry level electric vehicle takes takes around 8.5 to nine hours to fully recharge the battery. Unlike fuel stations, charging infrastructure is limited, even in a city like Bengaluru, India. Many apartment associations do not permit private charging station in the pillar adjacent to the corresponding car parking space.

For electric cars, I initially felt that I can manage with publicly available battery chargers in Bengaluru. After visiting the battery charging stations and talking to several owners and potential buyers of of electric cars, I realized that the idea is not practical.

Also, with respect to usage of limited battery charging stations in Bengaluru, there is competition from large number of electric scooters which are quite popular in Bengaluru.

Car ownership may be costly, and the initial cost of ownership isn't the only thing that can break the bank. The many recurring expenses that come with owning a car can quickly mount up and have a big impact on one's spending plan. And purchasing an entry-level electric vehicle requires even more financial resources and supported infrastructure. And some of us, who can barely manage to buy an entry level petrol vehicle, in India, will not be able to afford an electric vehicle as of now.

"Jezz Bezos and Elon Musk emit more carbon pollution in 90 minutes than the average human does in their entire life."

“Half of the world’s emissions come from the richest 10% of people. The wealthiest 1% by income account for 16% of emissions, which is more than the poorest two-thirds of people in the world,”

Gizmodo · Billionaires Are the One Case Where Personal Choices Can Affect Climate ChangeA new study found that half of the world’s carbon emissions come from the richest 10% of people.

Forgive me the christian meme here, but as far as I see it, OpenAI’s Sam Altman has allready entered the territory of faith by suggesting we should start geoengineering the planet to supply enough power for huge #AI’s, so I’ll excuse myself.

Generative AI has really become the new Tower of Babel. Silicon Valley is ready to burn the planet in their quest to build a machine god.

Humans really never change. Same story again & again.

Over the past few years, Nike has talked a good game about plans to shrink its carbon footprint, and @ProPublica has put in the hard yards to keep the mega brand honest. Most recently, reporter Rob Davis has zeroed in on private jet usage. His latest report shows that, rather than becoming more transparent, Nike is taking steps to make tracking execs’ plane usage harder.

ProPublicaWe Reported on Nike’s Extensive Use of Private Jets. The Company Just Made It Harder to Track Them.Since our story, the company has added its planes to a popular Federal Aviation Administration program that makes it harder to see where they’re going.

If you’re a member of the top 1% of earners in the U.S., there’s a fair chance your carbon footprint is bigger than you thought. A lot bigger. On average, 1,388 times bigger compared to someone in the bottom 50%. But don’t worry if this is news to you. A new study says the vast majority of people don’t know the true size of this inequality. @sciencefocus explains: flip.it/X0rgQz

Continued thread

"...while reducing our #CarbonFootprint is definitely the right idea, neglecting issues like #biodiversity in the pursuit of lessening #emissions will only worsen the problem in years to come."

The answer isn't a singular focus on one facet of the causes of our #ClimateChange catastrophe, but on doing Everything, Everywhere, All at Once, and recognizing when plans go wrong and adjusting accordingly and continually.

What if I told you that most promoted actions about climate-friendly software are misguided?

Backing data for that claim and my opinion on the low-hanging fruits:

Key takeaways:
* Pick servers in carbon-neutral or low-carbon datacenters first
* Optimize for the perceived performance and battery life
* Don't be the one that will make your users change their device
* Sometimes, ideas aren't even worth their impacts
