The 1.5°C limit means we can avoid the worst of the climate crisis

The IPCC Special Reports SR1.5 and SR Land are clear: limiting global warming to 1.5°C is crucial to avoiding the worst impacts of climate change. Compared to 2°C of warming, a 1.5°C limit would significantly reduce the severity of extreme events—for example, mid-latitude heat waves would be, on average, 1°C cooler. It would also lessen disruptions to human and ecological systems, with 158 million fewer people affected by changes in crop yields.

Keeping warming below 1.5°C would mean substantially fewer people facing water scarcity, food insecurity, and extreme poverty. While this goal remains within reach, achieving it requires immediate and rapid action. Stringent emission reductions must take place in the very near term to cut projected 2030 CO2 emissions by half.

To stay on a 1.5°C pathway, CO2 emissions must peak immediately and reach net zero by mid-century, with total greenhouse gas emissions following suit in the second half of the century. The time to act is now.

There are multiple, feasible, and effective options available now to reduce greenhouse gas emissions and adapt to human-caused climate change.

The greenhouse gases

Greenhouse gases contribute to climate warming by allowing short-wave solar radiation to pass through the atmosphere while trapping heat radiated from the Earth's surface.

Global climate targets

In 2015, governments adopted the Paris Climate Agreement, committing to “holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C.”

EU climate policy

Under the Paris Agreement, the EU has set a target of cutting emissions by 55% by 2030.
