Carbon Clock

This is the carbon clock

It has been counting down since 2018 warning of a crucial tipping point – when an average global temperature increase of 1.5 degrees is unavoidable.

Grounded in science

The original carbon clock was created by the MCC (Mercator Research Institute on Global Commons and Climate Change) using IPCC data that shows how much CO2 can be released into the atmosphere before we reach the critical tipping points of 1.5°C and 2°C.

To see what our clock is synchronised to click ‘1.5°C scenario’ in the top right of the MCC clock.

An iteration of the carbon clock (the ‘climate’ clock) was displayed in September 2020 at the Metronome, a 62-foot-wide 15-digit electronic clock that faces Union Square in Manhattan by two artists, Gan Golan and Andrew Boyd.

They also created the fantastic shareable widget below.


The carbon clock is a great tool to inspire immediate climate action by highlighting the urgency of the climate crisis. We have a seven year opportunity to make a difference. To make sure this clock does not reach zero.

An Opportunity to Amplify

This clock should serve as a rallying cry for all organisations dedicated to addressing the climate crisis.

We want to help communicators use this evocative tool to encourage climate action through the creation of a clock that shows Australia’s emissions and our own shareable widget.

If you are involved with an organisation committed to climate action, have resources that could help develop the Australian carbon clock platform or have interest in sponsoring its development please contact advisory board member Matt Bray.
