To meet renewable energy targets by 2020, European countries have rediscovered wood as a fuel. But conservationists fear this new hunger for biomass could have disastrous consequences — like deforestation. But is burning wood for fuel always bad? DW visits an award-winning, model biomass facility in Germany to find out.

Building with wood is often associated with deforestation. But it's becoming an increasingly popular material used for sustainable building projects — if it's sourced from forests where the wood extracted equals wood replaced. We explore a sustainable wood building project in the heart of Germany to discover what's behind the appeal.

UN climate chief Patricia Espinosa says there is political will to curb climate change. She told DW once we speed up our transition to renewables and away from fossil fuels, we'll be on the right track.

Climate scientist Kevin Anderson is one of the world's leading authorities on carbon budgets. He told DW keeping global warming below 2 degrees is a choice — but it's one we have to make it fast.

The United States has teamed up with the Canadian government to work on a coal-fired plant that captures CO2. Carbon capture and storage (CCS) is controversial because it has the potential to extend the life of the coal industry around the world. But is it a good idea, when the world is trying to wean itself off fossil fuels like coal?

A new report shows rising CO2 levels in the atmosphere are about to make the world's oceans uninhabitable for many sea creatures, threatening entire ocean ecosystems.

UN climate summits have morphed into mammoth yearly events, involving not only complicated logistics but also a lot of CO2 emissions. Thousands of people fly in from all over the world to take part in the conference. Now there's some grumbling that the annual ritual has become a circus. Dave Keating spoke to some attendees at COP23 to find out whether they think it's really worth the trouble.

All around the world indigenous communities are being hit hard by the impacts of climate change. Yet indigenous peoples and their traditional knowledge can play a crucial role in the battle against climate change. The Paris Accord includes indigenous peoples as a key element to increasing climate protection. DW talks to Heather Milton Lightning from the Indigenous Climate Action group in Canada.

Genevieve Jiva is a Fijian activist from the Climate Action Network. Her country faces an existential threat from rising seas. That's why she's at COP23 campaigning for countries to urgently phase out fossil fuels.

Germany's reliance on coal to generate electricity is once again under scrutiny as the COP23 climate summit takes place this week in Bonn. Soft and hard coal remain the primary fuel the German national grid relies on to power the nation. This past weekend, more than 10,000 protesters took to the streets of Bonn, the former capital of West Germany, to push for an immediate phase-out of coal.
