Every year, more than 1,000 wildfires burn through hundreds of thousands of , releasing planet-warming gases and turning climate-saving assets to ashes.

With woodlands spanning almost 40% of Europe's total land area, the fastest-warming continent is to fight blazes as climate change drives hotter and drier weather, which is expected to by 2100.

Here is a look at how wildfires affect Europe, where temperatures are rising at about double the rate of the global average, and what is being done to protect communities and forests.

How much damage do wildfires inflict?

Data from 2024 shows fires burned (1 million acres), which is slightly above the average registered between 2006 and 2023.

Around 9,500 fires, including one on the outskirts of Athens, burned nearly 44,500 hectares of land in alone. had its worst year for forest fires since 2017, with 147,00 hectares affected.

The year 2023 was the fourth worst in terms of total burnt surface area at more than 500,000 hectares.

The deadliest fires in recent years happened in in 2018, when 104 people were killed in the seaside town of Mati, and in , where wildfires killed 66 people in 2017.

Wildfires are also releasing tonnes of planet-warming gases and destroying , exacerbating climate change and polluting the air, leading to respiratory illnesses.

Are wildfires getting worse in Europe?

Catastrophic blazes that once happened every 100 years will become by the turn of the century, according to scientists.

Greenhouse gas emissions from human activities have by around 1.3 degrees Celsius (2.3°F), leading to higher temperatures during extreme weather and sucking moisture from vegetation, turning it into fire fuel.

Forest and land management play a key role in limiting fire. But as people move away from rural areas to cities, lands are abandoned to nature, allowing growth of vegetation that fuels blazes.

As suburbs push into rural areas, there is more risk of people starting accidental fires or deliberately igniting blazes.

According to European Union data, more than nine out of 10 fires can be , including deliberate arson and fires started accidentally, for example, with the use of disposable barbecues. Fires can also be ignited via electricity lines.

Dry soil, low humidity and high winds then fan flames, and abundant fuel from deserted woodlands can lead to megafires which can overwhelm traditional firefighting techniques.

What is the EU doing to reduce risk?

Europe's civil protection unit is coordinating efforts to protect wildfire-prone countries, with 22 firefighting planes, four helicopters and 650 firefighters positioned in high-risk locations in France, Greece, Portugal and Spain.

EU countries are also , such as creating fire breaks and carrying out prescribed burns, in which fires are set and managed to reduce wildfires.

Hard-hit Portugal has and now dedicates more funds to prevention versus suppression. The proportion of total government spending on fire prevention measures has risen from 20% in 2017 to 61% in 2022.

However, a new report from the bloc's spending watchdog found that EU funds to prevent forest fires had been and based on outdated maps in several countries. One area selected for funds in Portugal was underwater, as the hazard map did not include a newly built dam.

The EU's landmark Green Deal aims to slow the impact of global warming and reduce fire risk by cutting greenhouse gas emissions.

But some member states are pushing to weaken rules meant to protect biodiversity - which forestry experts say is key to protecting woodlands from fires. These include the Law and regulations.
