Australia’s new emissions target is not “squarely in the middle of comparable economies". Towards the bottom of the pack of comparable countries, on key indicators. But Australia is coming to the party, and that counts for a lot.

Australia will reduce greenhouse gas emissions by 26-28% below 2005 levels by 2030. Experts respond.
Access to the grid has crowded out solar in some places in India.

Given existing technologies, expanding access to electricity almost always increases CO2 emissions. There are real trade-offs between addressing poverty and climate change.
What lessons are there in the beer industry?
The beer industry is a fascinating microcosm of the larger landscape of today’s business environment. Students can examine a range of questions facing businesses, through the beer industry.
Raise the (Thames) Barriers!
With the sea level set to rise up to 1m by 2100, cities around the world must adapt, if they're to avoid disaster.
Energy efficiency has driven the recent fall in electricity demand.
In June this year, forecasts revealed residential and business demand has risen for the first time in five years. The trend could be here to stay, according to a report released today from the Australia Institute.
To get to zero emissions, we’ll have to reform our energy sector away from fossil fuels.
To avoid dangerous climate change there is a finite amount of greenhouse gas emissions, in particular CO<sub>2</sub>, that we can add to the atmosphere - our global carbon budget. If we use our budget wisely, we have until about 2050 to transition to zero net emissions. But how do we get there?
Switching to solar power can deliver over 100 million tonnes of emissions reductions by 2030.*
Australia can reduce its greenhouse gas emissions by 50% below 2005 levels by 2030, according to analysis by ClimateWorks.
What if jet fuel could be grown sustainably?
What if you could grow biofuels on land nobody wants, using just seawater and sunlight, and produce food at the same time?
Australia risks becoming a ‘fossilised’ economy unless we take action on climate change without delay.
Economic studies on the costs of climate action share a common message: action on climate change is cheap, and delaying it will be costly.
Bjorn Lomborg seems to irritate the hell out of many environmentalists.

Bjorn Lomborg seems to inspire anything but consensus, but is his approach all that bad?
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.
It’s (reverse) auction time for the government’s emissions-reduction plans.
The federal government is holding the first reverse auction to award contracts for its Direct Action emissions plan. Here's how it will work.
Car makers pay close attention to the emissions regulations in the countries they export to.

Unlike many countries, Australia does not have mandatory greenhouse emissions standards for cars - meaning that manufacturers are free to sell their least efficient, most polluting vehicles here.
The US proposes to meet its climate targets through regulation, including reducing carbon emissions from coal power plants by a third below 2005 levels.
The United States' post-2020 climate target raises many questions for this year's global climate talks, and puts pressure on Australia to raise the stakes.
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.
Observations from space have shown the world overall is getting greener despite deforestation and drought.
A new investigation of satellite records reveals that the Earth is getting greener, despite ongoing deforestation in Indonesia and South America.
Tracking the world’s efforts to reduce greenhouse gases.
In the lead up to climate meetings in Paris at the end of the year, countries will release draft targets - the framework of a possible global climate deal. Follow our interactive map as we track these targets.
Countries are working towards meetings in Paris in November that could see the first global climate deal since the Kyoto Protocol.
Ahead of meetings at the end of this year in Paris, countries will submit draft contributions for a global climate deal. The goal: reducing greenhouse gases beyond 2020, and ultimately keeping global warming below 2C.
Switching to alternative energy sources, such as renewables, and using more electric cars could double Australia’s energy productivity.
