Stop mangrove destruction in Indonesia to slow climate change

Prodita Sabarini

8th August 2015

The loss of Indonesia's coastal mangrove forests for shrimp farming is a huge source of carbon emissions, writes Prodita Sabarini. But equally, a policy flip to preserve and recreate mangroves offers a major climate win. more...

Obama unveils deep cuts to power plant emissions

Dan Roberts / Guardian environment

4th July 2015

Obama has delighted climate campaigners with this 'clean Power Plan' that will force states to make deep cut in carbon emissions from power stations, writes Dan Roberts. But not everyone is happy, and legal challenges loom. more...

The world is already committed to a six meter sea level rise

Pete Dolack / Systemic Disorder

24th July 2015

The climate change discourse rarely looks beyond 2100, writes Pete Dolack. Maybe that's because even at current levels of CO2, we are committed to thousands of years of warming and polar ice melt that will raise sea levels by at least six meters. However the implacable imperatives of capitalism mean there's little prospect of change for a long time to come. more...

Scrapping 'zero carbon' homes is policy vandalism

Gordon Walker

20th July 2015

The UK Government has ditched the requirement for new homes to be 'zero carbon' from April 2016, writes Gordon Walker. With builders already geared up to meet the challenge, this needless reversal will raise energy bills and carbon emissions for a century or more to come, and send out all the wrong signals for the Paris climate talks. more...

Meat - the climate opportunity we can seize at every meal

Dora Marinova & Talia Raphaely

9th July 2015

Meat is already a huge contributor to climate change, write Dora Marinova & Talia Raphaely, and as 'atmospheric space' for greenhouse gas emissions contracts, its importance will only increase. The good news? If rich countries were just to eat less of it, there's a huge climate win there for the taking! more...

OECD chief: World must ditch coal, go renewable

Alex Kirby

5th July 2015

The secretary general of the OECD group of the world's 34 richest nations has issued a dramatic plea to its members to act now to end 'unabated coal' burning, writes Alex Kirby, and invest in renewables around the world to prevent climate disaster. more...

Global emissions stay flat thanks to renewable energy surge

Alex Kirby

30th June 2015

The world economy and energy use both grew in 2014 - but carbon emissions did not, writes Alex Kirby. The reason? The worldwide surge in renewables, especially in China, has reduced demand for coal in power generation. more...

Worried about climate change? So why aren't you vegan?

Chris Lang

1st July 2015

You might be forgiven for thinking that climate change is all about fossil fuels, writes Chris Lang. But with livestock farming causing around a sixth of global emissions, there's one quick, cheap way to cut our carbon footprints: go vegetarian, or better still, vegan. So what's taking us so long? more...
Scientists had thought that Arctic rivers like the Kolyma in Siberia carry dissolved carbon from melting permafrost to the oceans. They were wrong - it's all emitted to the atmosphere as CO2. Photo: Магадан via Flickr (CC BY-NC-SA).

Thawing Arctic carbon threatens 'runaway' global warming

Tim Radford

14th May 2015

Arctic warming is releasing ancient organic matter that's been deep-frozen for millennia, writes Tim Radford. And now scientists have discovered its fate: within weeks it's all digested by bacteria and released to the atmosphere as CO2 - with potentially catastrophic impacts on climate. more...
The Middelgrunden marine wind farm near Copenhagen is a wonder of 'green' energy technology. But even this has its toxic footprint, in the mines that produce the neodymium that's indispensable to their operation. Photo: Andreas Klinke Johannsen via Flickr

Renewable energy alone cannot reverse global warming or make a sustainable world

Pete Dolack

25th May 2015

The renewable power boom is excellent news for people and planet, writes Pete Dolack. But let's not get carried away: much energy that claims to be 'renewable; like biomass and big hydro, is no such thing. And greening our energy is just one of many steps to a sustainable world. The greatest challenges - like tackling the monster of infinite 'growth' - all lie ahead. more...
The rate of growth in China's emissions from fossil fuels has been declining for a decade - but in 2014 it switched into reverse.

China's fossil fuel emissions fell 3% in 2014

Lauri Myllyvirta / Greenpeace EnergyDesk

27th February 2015

China has just recorded its first fall in emissions from burning fossil fuels in 15 years, writes Lauri Myllyvirta. The sharp decline has surprised analysts, and reflects the fast growing proportion of renewables in the country's power supply. more...

Coal's dark cloud hangs over Germany's energy revolution

Henner Weithöner

22nd January 2015

Germany cut emissions and boosted renewables to record levels last year, writes Henner Weithöner. Yet the country's coal burn remains the EU's highest - and ambitious emissions targets can only be met by closing coal-burning power stations. more...

UNEP calls for world to be carbon neutral in 40 years

Helle Abelvik-Lawson / Greenpeace Energy Desk

3rd January 2014

If the world is to hit crucial climate change targets, emissions must reach 'net zero' much sooner than previously thought, by 2055-2070, writes Helle Abelvik-Lawson - and then go into reverse as we pull CO2 out of the atmosphere. more...
