If Indian bakers are anything like French they will only change if it's economical viable to them. Somebody has to make the change, have better bread or similar, sell it cheaper than non-adapters, make more profit than regulars and open a few bakeries. Only then they might be willing to invest the time , energy and money to make a change. More to save their own jobs than to do something for a change for the public good.
Here in France long time they're using electric ovens. So long so that romantic green minded folk liked to buy bread that was cooked in a fire lid oven and forgave the baker who mostly had burned bread. And now i come to think of it, nobody of us even ever wondered why? It was just a matter of it was done this way in the past, so it must be better...
In general i would say that life works in that way, people do not like to change. Be the change. Or think of a work around. If you're worried of too many forests getting cut down, find a way to plant forests. If air polution has your interest it might be easier to change the mindset of bureaucrats around public transport, because their jobs it is to make regulation, and a change in regulation towards more air friendly ways means they find work. Maybe copy some European ways, like that old vehicles cannot come into the city centre. Which i hate by the way, because i cannot go into the city because being a poor country bum let's me live with a shitty second hand diesel van.
But in this case you'll need the people's mind to be there where they find their minds in a place where they have the luxury to thibnk asbout the environment in the first place. I would say that happens after everybody in the big cities is fed and housed. Of what i know of India that still isn't the case. Poverty is still preoblem nr1, and the industrialisation pulling people out of poverty is causing the air problem.
In my opinion poverty and housing can never be solved in a city, because megapoles attract wealth and siphon it off from the country sites, empoverishing those, which causes country bums to leave the country side for the cities, causing the very problems the cities aim to solve, but never will because of their scarcity creating nature. The solution is that people start living in harmony in the country site, which they might if they realize that real wealth is where nature is still abundant, property prices low and people friendly and not specialized in jobs narrowing their human capacities/ specializing. Nature is everlasting abundance and rocket mass heaters have their place there in making people realise we're infinite energy and solution finding nature ourselves if we chose to be in harmony with nature. Cities do not reinforce these qualities.
