Rising electricity demand could be here to stay

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.

Australia can stop greenhouse gas emissions by 2050: here’s how

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?

Wait and pay: action on climate change is cheap, delay is costly

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 again

Bjorn Lomborg seems to inspire anything but consensus, but is his approach all that bad?

Could Australia become a dumping ground for high-emission vehicles?

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.

How the US’s post-2020 climate target could fit into a global deal

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 extreme climate forecast puts energy giant in a bind

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.

Explainer: how countries could come to a global climate deal in 2015

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.

Australia could double its energy productivity by 2030: report

A new report shows Australia can and should double its energy productivity, increasing economic productivity while reducing greenhouse gas emissions.

February carbon dioxide levels average 400ppm for first time

We have hit a new milestone in carbon dioxide levels: the average for February topped 400ppm. It's the first time this has happened in the northern winter, when levels are typically lower than in summer.
Renewables or oil? The former means betting each-way on energy storage. The latter means hoping to pull off a trifecta on carbon storage. Hans Engbers/Shutterstock.com

Only a mug punter would bet on carbon storage over renewables

The question of whether the future will be powered by coal and oil or by renewable energy is crucially important, both to the medium-term future of the Australian economy and to the long-term future of…
