greenflation noun [U]
/ˌgriːn.ˈfleɪ.ʃᵊn/
an increase in prices resulting from the move to a green economy

Vaibhav Chaturvedi, a fellow at the Council on Energy, Environment and Water (CEEW), sees “greenflation”, or the costs associated with going green, as a concern, especially in the short-term. “Underlying commodity prices are rising everywhere in the world,” he said. Prices of metals such as tin, aluminium, copper, nickel-cobalt have risen by up to 91 per cent this year. These metals are used in technologies that are a part of the energy transition.

smog tower noun [C]
UK /ˌsmɒg.ˈtaʊəʳ/ US /ˌsmɒg.ˈtaʊɚ/
a tall, narrow structure that uses fans and filters to clean the air in an area where there is a lot of air pollution

India’s capital New Delhi has opened its first “smog tower”, aimed at reducing the air pollution blamed for thousands of premature deaths every year, but experts are sceptical … The tower cost $2m and critics say erecting a sufficient number to clean the air substantially across the city would cost huge amounts of public money, and that efforts would be better directed at the sources of the smog.
