Trading and sustainability -does every trade leave the exchange?

Hi! I do some trading using bots, but would like to know more about the environmental impacts og trading in particular, and to avoid doing harm to the environmental/climate.

POW cryptos like BTC use a lot of energy as we all know. Yes it is renewable to some degree, however most if not all renewables also have significant negative consequences more in terms of damaging nature where it is built.

I wonder how the trading of these on Binance actually works. How much energy does one trade use? Do they all leave the exchange? It seems logical to me that all trades must go in to the blockchain sooner or later, right?

Would love some insight here to minimize the harm of my trading.

Thanks you ????
