With the US announcement that it would withdrawl from the Paris Accord, several American states are mobilizing to reduce their greenhouse gas emissions.
Every December Australia’s air travel peaks, as we travel to family and friends (or flee on holiday). Many buy carbon offsets for these flights – but what do they actually do to our carbon emissions?
Sun, wind, waste biomass, geothermal, tides and waves: all these energy sources in Sydney’s backyard add up to a zero-carbon energy solution for the city.
The CO2 we produce when we put up buildings is large and virtually unregulated.
After three years in which global carbon emissions scarcely rose, 2017 has seen them climb by 2%, as the long-anticipated peak in global emissions remains elusive.
Green détente options could help South Korea ease the diplomatic tensions in the region.
Amu Coal a Kenyan and Chinese consortium is set to build a coal plant in an area untouched by industrial development. The emissions alone will double the country’s energy sector’s CO2 emissions.
Government payments to keep Australia’s oldest coal plant running amounts to a carbon subsidy. It’s worth looking at the financial – and carbon –
cost.
It’s a good thing that cities aspire to lead the way in acting on climate change in the absence of stronger national action. But a closer look reveals the limitations of current city-based efforts.
It would take a lifestyle upheaval to drop most Australians’ household emissions to a sustainable level. Even many of us who urge equitable action on climate change act as if this doesn’t apply to us.
Tonight on the ABC’s Catalyst, scientist Tim Flannery asks if seaweed can save the world. It’s a bold claim for algae, but seaweed could play a key role in keeping climate change in check.
When utilities plan investments, they think decades ahead. A recent study shows why power companies should be spending more on renewables despite the Trump administration’s tilt toward fossil fuels.
The great dream of cars running on sustainable petrol has not bitten the dust. Here’s why.
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
The current rise in atmospheric carbon dioxide levels is unprecedented in the past 800,000 years. As our video explains, ice cores track human changes to the atmosphere that are far beyond natural.
Australia’s road emissions have plateaued – last year showed the smallest reduction on record.
The Australian market is awash with highly polluting cars. But there are a couple of key resources to help you find the best vehicle that fits your needs.
Diesel engines have been demonised for their emissions but the technology has already cleaned up its act.
Engineers are hoping to iron out a century-old technology that could reduce shipping emissions.
