Methane is a destructive greenhouse gas. Emissions often escape from fossil fuel facilities. Plugging the leaks is a simple solution. But because they are invisible to the naked eye, it takes detective work to find them.

As world powers prepare to begin crucial climate talks at the COP27 summit in Egypt, we speak to Chiara Martinelli, director of the Climate Action Network Europe, which describes itself as Europe's leading NGO coalition fighting dangerous climate change.

The United States and Norway "challenge" highly polluting shipping sector to reduce emissions at UN climate summit.

From Roman Abramovich's yacht and Taylor Swift's private jet to the sprawling warehouses and data centers of Jeff Bezos' Amazon, the lifestyles and business interests of the world's billionaires are baking the planet.

Motorcycles with swap batteries and buses with solar panels on their roofs: African innovators have been working on ideas that support the climate, the local population and promote the "Made in Africa" brand.

As European countries struggle to reach their targets on reducing carbon emissions, one small landlocked country in central Asia stands as an example to the world. With nearly three quarters of its territory covered by woodland, Bhutan, with a population of around 780,000, claims to be a carbon-negative economy.

The European Commission has proposed a drop of 90% in emissions in heavy vehicles by 2040 as compared to 2019. From 2030, new city buses should be zero-emission vehicles.

Last year, Germany produced 10 million tons of greenhouse gases less than expected. But, individually, the energy and transport sectors are still lagging behind.

France's greenhouse gas emissions are down for the first time since the post-Covid spike. Cipeta, the institution that measures carbon emissions, reports that they were reduced by 2.5 percent in 2022 compared with the previous year.

The US government wants to turn domestic coalfields into green energy centers in an effort to combine climate protection with job creation. But those affected have little trust in the policy, reports Sabrina Kessler.

Faced with the climate crisis, more and more young people are denouncing government inaction. This movement has now reached France's top universities, where students and graduates alike are denouncing an education system that does not take environmental issues into account. Some recent graduates – from Sciences Po university, business school HEC and engineering school École Polytechnique – have decided to take action, from making radical career changes to shaking up courses at their alma maters. FRANCE 24's team went to meet them.

With more people on the move, carbon dioxide emissions from transport are increasing each year. To meet climate goals, the sector needs to slash its dependency on fossil fuels.
