Reducing Indoor Carbon Dioxide

Elevated carbon dioxide impairs decision making. And it doesn’t take a lot of carbon dioxide either! Normal atmospheric carbon dioxide has risen from 280 ppm to 415 ppm in the past century, but in poorly ventilated buildings and stuffy meeting rooms, concentrations can easily get into the thousands of ppm. Unfortunately, above 1000 ppm there’s a substantial and measurable…

Segment and the GDPR

In less than six months, your business will face the greatest regulatory change in data privacy policy in the last 20 years: the EU General Data Protection Regulation (GDPR).
