Greenhouse emissions from the aviation industry are still largely unregulated. The prospect of regulations for US flights sounds like progress, but it won’t happen without an elusive international consensus.
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 Grattan Institute has reported that the costs of solar panels have outweighed the benefits by almost A$10 billion in Australia. But the real benefits of cutting greenhouse emissions are much larger.
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.
Is nuclear power worth it? No, says Mark Diesendorf – it’s never been a major world energy force, it has caused huge accidents, and its greenhouse emissions are higher than many people realise.
Federal environment minister Greg Hunt has hailed the first round of Emissions Reduction Fund auctions as a “stunning result”. But extrapolating the numbers puts Australia behind on its carbon targets.
The Climate Change Authority has recommended Australia cut greenhouse gas emissions 30% below 2000 levels by 2025. While sensible, the government is unlikely to accept, and the target misses bigger opportunities to cut emissions.
A report from Australia’s Climate Change Authority recommends cutting greenhouse emissions by 30% by 2025 if the country is to be seen as a good global citizen in this year’s climate negotiations.
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.
The Guardian’s divestment campaign is targeting charitable research trusts. John Quiggin says they have a moral duty to divest fossil fuels, regardless of the temptation to research technological climate fixes.
Meat uses a lot of resources - between three and ten times as much as plants for the same amount of protein. The rich world might be slowly losing its taste for meat, but the developing world isn’t.
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.
Emissions fell by six times the rate in the five years before the carbon tax than they did under the carbon tax. – Environment minister Greg Hunt, The Guardian, January 17, 2015. Australia’s total greenhouse…
Could what we flush down the toilet be used to power our homes? Thanks to biogas technology, Australia’s relationship with organic waste – human and animal excreta, plant scraps and food-processing waste…
Earth’s climate is changing rapidly. We know this from billions of observations, documented in thousands of journal papers and texts and summarized every few years by the United Nations’ Intergovernmental…
