How wild animals secretly combat climate change—and why it matters now

Wild animals play a far greater role in fighting climate change than previously recognised. A growing body of research shows their presence boosts carbon storage, strengthens ecosystems, and even helps cool the planet. Now, global conservation groups are pushing for their protection to be formally included in climate strategies.

Forests with healthy animal populations store far more carbon than those without. In the Congo Basin, areas with elephants hold around 7% more carbon. Tigers also make a difference—regions where they thrive lock away significantly higher levels of carbon. Meanwhile, seed-dispersing animals help tropical forests absorb four times as much carbon by spreading plant life.

Oceans benefit too. Large fish like tuna, mackerel, and sharks contribute to 'blue carbon' storage when their bodies sink to the seabed. Sea otters have an even bigger impact, increasing carbon capture in kelp forests by up to 12 times. In Antarctica, penguin droppings release gases that form clouds, which help reflect sunlight and keep temperatures lower.

The evidence has led to official action. On 10 October 2025, the International Union for Conservation of Nature (IUCN) passed a resolution urging governments to recognise wild animals as a climate solution. The measure calls on the IUCN's Director General to push for their role in climate mitigation to be acknowledged under the UN Framework Convention on Climate Change (UNFCCC). This follows a 2022 agreement at the Convention on Biological Diversity, which highlighted animal conservation as a key tool for reducing climate risks.

The Intergovernmental Panel on Climate Change (IPCC) has also weighed in. Its Sixth Assessment Report warned that losing local species weakens ecosystems, making them less resilient to climate change and less able to provide essential services.

The push to protect wildlife is now tied directly to climate goals. By safeguarding animals like elephants, tigers, and sea otters, conservation efforts could help ecosystems store more carbon and withstand extreme weather. The next step will be integrating these findings into global policies—starting with the UN's climate negotiations.
