We are working on helping these enterprises get aware of their responsibilities and adopt Sustainable practices. Reducing usage & as much as possible, using sustainable alternatives in such cases, could help.

Of *human* global CO2 emissions. Human CO2 emisions represent 5% of global emissions.

Reminder of CO2 emission figures: - vegetation & animals = ~440 Gt every year. - oceans = ~330 Gt every year. - human activities = ~30Gt every year.

The whole point of concrete is it’s load bearing properties. Hempcrete has 5% of the compressive strength of concrete so it’s not useful in terms of any significant replacement
