The current problem with EV is that the car are charged by burning fossil fuel. So zilch reduction. Either you burn petrol/diesel using non-EV vehicles or you burn coal at the power plant by charging your vehicle.

The only method that will help is by using electricity generated by solar / nuclear energy. However remember that using nuclear energy comes at a tremendous cost of storing lethal spent nuclear fuel.

There is a calculation which shows that efficiency of cola burnt and hence emissions generated per unit is lower for power generation rather than individually in cars for the same amount of energy even taking into account T&D losses. but thats only operational. the actual emissions for mining of Boron etc needed for the Battery impacts a lot more.

Since scope 3 norms deal with cradle to Grave we need to look at batttery and fuel right from the origination from earth for all then components to its final destruction back to earth.
Batteries in its current form as still not there unless we move to mass solar charging and economic reuse back.

Hydrogen theoretically has a far better footprint once we figure out the right way to get/store/transport green hydrogen. Thats where india will move perhaps unless we get batteries with better tech !

Then there is also fuel cell which have still not reached the promise they made...
 
As large numbers enter “middle class” economic categories wastefulness does seem to increase as does “conspicuous consumption”, keeping up with the kumars and in general mindless imitation of a lifestyle driven by peer pressure, movies and brand following.

In the past few years the new Indian middle class also has discovered foreign tourism and road trips.

Is this sustainable you may ask?
The answer is “you probably should not” ask. It’s our right to become like ———___( fill in the name of the country of your choice (Singapore, Amrika are popular amongst our politicians)

We have few if any role models to learn from and emulate in public life or even in literature, TV or movies.

For anyone interested in alternative lifestyles there is a fascinating series called “where wild men are” with Dan Fogle.

Very true. although in the above I estimate we are talking of less than 5% of the population earning > 5 lakhs a year while on the other side more than 50% of the country earn less than 50K a year and are on subsidies.
All the above issue are specific only to the perhaps 5-10% which by itself is a pretty large number compared to most countries but still a minority in terms ot policies of the country as unfortunately they dont have the money to be sustainable but only to survive.

I would guess its even more than 7x..maybe 10-20 and yet the truly poor are 100X times the number of rich ( <.5% of the population)
it might just be even-stevens. But again In terms of absolute contribution the largest contributors are Energy generation and losses, commercial transportation and Cement/Steel/chemical industries which impact all directly or indirectly

Somewhere govt policy for all developing/under-developed nations have to balance the cost of subsidy vs development initiatives at a time where its these industries that fuel further development. Unfortunately its a at a time where the west already has made these developments at the expense of the environment much over the threshold.
Not easy decisions to take I guess

Interview: How putting a price on nature could help protect the environment

Siddarth Shrikanth, author of ‘The Case for Nature’, asks how much is nature worth and if recognising its value can turn the tide on ecological destruction.

Amid the clamour around the issue of subsidy this puts it in a perspective…

While subsidies accounted for more than 2 percent of the country's GDP in 2014-15, in 2024-25, the share is likely to be 1.32 percent, similar to what the government spent in 2019-20. As a share of the Budget, subsidy spending has nearly halved over the decade.

Absolutely, household solar power generation, connected to the grid to offset user costs is definitely a major positive shift that many governments are making.
Storage of power for EVs has also improved significantly from the lead acid batteries though waste disposal of lithium batteries are still a concern. Lithium is still expensive and recycling is the norm.
Centralised power generation is still better than every household running a petroleum fuel generator.
In addition it’s easier to advocate and help governments to shift to cleaner energy sources over time.
If not in our lifetime then maybe for our children and future generations.
The ICE vehicle producers and petroleum industries are formidable opponents fighting tooth and nail to preserve their wealth.
But most ICE vehicle producers have started producing EVs now.
I would liken the change as being similar to the shift from Rotary dial phones to the first gen mobile phones or CRT TVs to LCD panels.

For every diwali firework reduction there is a terrorist bombing/war as well as AI server farms which will only go up. In fact many have reclassified Nuclear power as Sustainable fuels so wonder where all of this ends up.
So we might end up blowing/poisoning the world even before climate change get a chance to do its thingie

And the jury is still out on EVs..eg the environment cost of mining for battery components and its scalability. Additionally power generation itself is one of the major contributing causes of increase in emissions

The problem is definitely there but the true solutions may take time

It has been long, and I mean really long since I last burst a cracker. I guess between 2000-2005 was the last time I did, so it's been almost 20 years since I stopped bursting crackers.

I mean it's right there and you can feel it. The noise it makes that hurts our ears, sudden panic to elders. The pungent smoke it produces. It causes so much air pollution, but many don't understand that.

Maybe a few rockets is ok if you can't go without it but the ground level crackers should be restricted.
 
Reduce, minimise and if possible avoid polluting activities on a personal level is a good guideline to live by in these times.
 
How many folks here have installed Solar panels and or home inverter backup batteries in their house? How many own a two wheeler EV or 4wheeler? May I please have a quick conversation with you on DM. ( I work in the space)
 
Hi,
I have solar power at my place near a forest and an audio set up running on it.
I have an electric scooter and an electric pedal assist bicycle.
Several years ago I had a Reva (the original Indiyan EV)
Happy to discuss my experiences with these though my technical knowledge on all these is limited.

Climate researcher fired for refusing air travel wins compensation

A climate researcher who was fired from his job for refusing to take a flight back from a work trip has been awarded compensation in court for unfair dismissal. Gianluca Grimalda has been reducing his air travel since 2010. But in 2023, his employer, the Kiel Institute for the World Economy...
