Three years after the Paris Agreement, negotiators have finally agreed (most of) the rules for its implementation. But there is still no way to compel countries to deepen their climate ambitions.
Delicious, nutritious… and emissions-intensive.
Most consumers underestimate the greenhouse emissions associated with different foods. But environmental labels, similar to existing nutrition information, can help us make lower-impact choices.
The lack of political will to meet emission targets could see more extreme flooding in the future, like what happened the Québec community of Gatineau in 2017.

Achieving climate objectives is economically realistic, but won't be possible without the support of a real transition strategy that is still lacking at all levels of government in Canada.
Economists have searched for the mythical balance between the cost of climate action, and the future cost of doing nothing.
For decades, economists have pondered the 'social cost of carbon' - the price worth paying to avoid the future costs of greenhouse emissions. But a new analysis suggests this quest is impossibly complex.
Paris is burning.
The gilets jaunes protests show we need to fight inequality for a just transition to a low-carbon society.
A better tomorrow?
Brexit may be an unexpected boon for the UK's climate leadership. Here's how the UK can seize the initiative.

Hundreds of US cities have pledged to meet the carbon reduction targets in the Paris climate accord. Now it's time for them to start showing results.

We are on track to reach 1.5°C of global warming within 16 years according to new data.
Heavy rains driven by a cyclone in Sana’a, Yemen.
The frequency of intense tropical cyclones is increasing in the South Indian Ocean - a region that previously didn't have these.
Conspicuous consumption is one of the main ways that China-born migrants come to mirror Australian society.
Australian cities are world-leading – in the worst sense – for resource use and greenhouse emissions. China-born residents have embraced these consumption patterns, which is bad news for the planet.
Working together, people and technology companies can make a lot of progress.
Amazon, Facebook and Google have lofty goals for their effects on global society. But people around the world are still waiting for the positive results. Here's what the tech giants could do.

Burning natural gas produces less greenhouse gases than coal or oil. But the methane emissions associated with natural gas production and liquefaction threaten to erode its environmental benefits.

Raising livestock has clear impacts on the environment, but contrary to what many critics say, it is not the biggest driver of climate change.
Many of Australia’s biggest emitters have not yet engaged with the Emissions Reduction Fund.

The federal government has signalled its intent to prolong the Emissions Reduction Fund. But surveys of business leaders reveal widespread cynicism about a scheme perceived as politicised and bureaucratic.
Australia has just two decades to put itself on the path to zero greenhouse emissions.

The world needs to be carbon-neutral by mid-century to give ourselves a chance of holding global warming to 1.5C. With around 1% of the global carbon budget, Australia needs to rapidly do its share.
New Zealand’s emission reduction target for 2030 is to bring emissions to 30% below 2005 levels, and to be carbon neutral by 2050.
With consultation underway to improve the New Zealand emissions trading scheme, experts argue that a reserve price on emissions units could help rebuild confidence in low-emission investment.
Is the sun setting fast enough on coal-fired power?
Australia needs to accelerate its transition to clean energy, and not prolong the use of high-polluting, coal-fired infrastructure. Otherwise it risks missing out on an economic windfall.
Australia’s exported greenhouse emissions are higher per person than Saudi Arabia’s.

A new report reveals Australia is lagging behind most wealthy nations in working towards the globally agreed goals. It's performing particularly badly on climate and environmental indicators.
The latest Australian Environmental-Economic Accounts tell us waste production is rising with GDP, but the information is incomplete and widely ignored.
Water and energy use are becoming more efficient, which is good news for both the economy and the environment. But Australia has yet to realise the value of national environmental accounting.
A jumble of steel scrap.
If the US were to stop dumping these valuable metals in landfills and to cease exporting them as cheap scrap, its imports could fall, and there would be less of these metals being made from scratch.
