US President Barack Obama has unveiled the United States’ most comprehensive climate policy so far.
US President Barack Obama's new climate plan aims to cut greenhouse emissions from the nation's coal-dominated power sector by 32% by 2030. Will it get through, and how will it affect this year's climate talks?
California has realised that investing in renewables is smart economic policy.

Ramping up investment in renewable energy would put Australia on a footing with competitors such as China, Germany and California, which are set to reap the economic benefits of this emerging sector.

The controversial Shenhua Watermark coal mine in New South Wales recently cleared another hurdle along the way to being granted full approval to proceed. But there are major environmental risks which should still call the project into question.
The latest coal mine approved in Australia is destined for exports.

International and domestic forces appear to be conspiring to significantly ratchet up the pressure on Prime Minster Tony Abbott’s climate policy.
Last week’s G7 meeting showed that turning our backs on fossil fuels altogether is no longer a fringe idea.

Advocates of climate action have been saying it for years - we need to wean ourselves off fossil fuels completely. And now, the leaders of the world's richest countries have started saying the same.
The G7 leaders are hoping to point the world towards a low-carbon transition.

G7 leaders have pledged to help end the world's fossil fuel use by the end of the century. It's a laudable aim, but decarbonisation can and should be done by the middle, not the end, of this century.

What to make of the announcement that we'll be off the hydrocarbons in time for the 22nd century? Dream on.
Old people in many countries are less likely to own a car.
Could developed countries' ageing populations help clean up the climate? New research suggests that a 1% increase in the proportion of over-65s delivers a 1.5% cut in carbon dioxide emissions.

The risks of rising carbon emissions means fossil fuel firms need new strategies now - for the sake of their businesses as well as the planet.

Issues of energy and climate will be solved by engineering, not climate science.
As China realises the unpriced costs of coal power, such as air pollution, coal production is starting to fall.
China's falling coal production suggests the world is waking up to the real cost of coal, calculated as $5.3 trillion in a report released this week.
You need to take a wider view to work out the true greenhouse emissions from nuclear power.

Nuclear power isn't 'zero-emission', as many proponents claim. Factor in uranium mining, power plant construction, and other factors and it has similar emissions to wind power. But that's still lower than fossil fuels.
Investment in technologies beyond the existing wind and solar could stagnate in the face of the government’s reduced Renewable Energy Target.
After months of deadlock, a deal has finally been reached to reduce the Renewable Energy Target, ending the uncertainty for industry but also risking an already sparse pipeline of future projects.
Amid the fanfare over the launch of the Powerwall, has Tesla’s Elon Musk struck a decisive blow for renewable energy?
Tesla's new home battery could help halve the costs of electricity for typical American households - all using existing technology. The fossil fuel industry is right to be worried.

Five years after the Deepwater Horizon oil spill, the Obama administration is looking to expand offshore drilling. Is it any safer today?
Every tonne of coal burnt is a tonne off the carbon budget to keep warming below 2C.
If we're going to limit global warming to less than 2C, Australia will need to keep more than 90% of its coal reserves in the ground.
Safeguarding rainforests is an area where the United Nations has made great strides - hopefully the Paris summit can deliver more of the same.

In the final part of his essay on the Paris climate talks, Nick Rowley explains how a successful deal, whether binding or not, needs to influence directly the domestic policies of the world's nations.
BP’s energy outlook would make it difficult to keep warming below 2C.
BP's Energy Outlook report forecast an increase in fossil fuel use by a third. That would make it difficult to keep warming below 2C.
Is Bill Gates’ desire to help tackle the world’s problems compatible with his foundation’s huge fossil fuel investments?
The Gates Foundation is being urged to dump its sizeable fossil fuel assets. Bill Gates cares deeply about world health and development, both of which are affected by climate, but will his charity divest?
