Climate Leadership
The Importance of
1.5 Degrees
1.5 degrees Celsius.
The fine line between crisis and opportunity.
The challenge that defines our era.
The target that unites global leaders.
Under the Paris Agreement, countries agreed to substantially reduce global greenhouse gas emissions to enable the long-term global average surface temperature increase to be kept well below 2°C above pre-industrial levels and pursue efforts to limit it to 1.5°C.
At COPs 26, 27, and 28, countries emphasized that the impacts of climate change would be much lower at a temperature increase of 1.5°C, compared with 2°C, and expressed their firm resolve to pursue efforts to limit global warming to 1.5°C.
