Hi! So what I usually do is think of why the environment is important to be mentioned in the scene. If your scene is a more 'active' scene then dont start by environmental description, rather you could start with inner dialogue/monologue that ties to it.
It's like 7 in the morning so excuse the poor writing but here's an example:
A had become a laughing stock. [sentences that emphasis how/why]. Even the city seemed to mock him for his stupidity; the screech of the electric train sounding too similar to fanatic cackling for his liking.
(Obviously yknow be more detailed than the above sentences). Then a sentence that connects it to your actual scene, continuing the above example it could be like:
Or maybe that was just B. She had been silently trailing after him ever since their narrow escape from the warehouse, but the slight curve of her lips spoke volumes. They stretched wider as he stumbled over a stray pebble; too lost in thought to notice it. [she says something].
But if your scene is more like he's walking through it with the intent of getting somewhere usually only mention what's either relevant to the plot (foreshadowing wise) or to a character. Or something like 'he's so late but this swarm of robot technicians talking loudly about xyz are walking really slowly in front of him'. Something that 1. makes his emotions/situation clear while 2. still being 'in the moment'.
You could also start with an active scene (like him talking to someone) then use that as an excuse for scene-building. An easy way to do it is use something he sees/hears/smells and connect it to a character or scene.
Like for example A is walking through [lane], gets to his destination, then maybe he notices B has a red flower in her hair just like the ones the street hawker was selling at [lane]. You could also use this for character development without info-dumping, something like 'of course someone like B would buy from the poor man who A spared but a glance to'.
I've rambled quite a bit, but I hope this helped! If you want I'd be happy to review an actual snippet and give feedback (honestly I've been meaning to get back into beta reading since a while).
