Berlin has just spent €1 million Euros getting CO2 sensors for schools - what an amazing way for students to learn about Climate change, respiration, and poor indoor air quality! Wonder who instigated- is this what having a scientist for chancellor does?

A/Prof Robyn Schofield I can’t find it but...I thought I read that Covid is carried farther/longer as an aerosol when CO2 is higher in a room so keeping CO2 low by opening windows/filtering can reduce spread. Does this sound right? I wonder if related to this decision

LC 🌻 A/Prof Robyn Schofield No, CO2 level is just a measurement of how good the ventilation is. So, low CO2 level equals better ventilation and lower COVID risk.

@WarkEnergy Plimsoll🚢 LC 🌻 A/Prof Robyn Schofield I understand -What do you suggest as a simple measure for ventilation indoors? People and businesses need guidance.
