Overarching goal in the Paris Agreement is
to hold "the increase in the global average temperature to well below 2°C above pre-industrial levels" and pursue efforts "to limit the temperature increase to 1.5°C above pre-industrial levels." |
Remaining global CO2 budgets from 2020 on according to the IPCC Sixth Assessment Report

We currently emit around 41 Gt per year.
We have summarised more detailed information here:
The MCC's CO2 clock is based on a compliance probability of 67% (1.5°C 400 Gt, 2°C 1,150 Gt) and
asks asks how long the global budget would last if global emissions remained the same.

Web app for calculating Paris-compatible national CO2 budgets:
The web app takes the two decisive criteria into account:
(1) current reality
(2) climate justice
