The UN climate conference brought some progress. A former UN official who has been involved in international climate policy for years explains what has to happen now for that progress to pay off.
The most comprehensive Australian carbon budget assessment completed to date shows the nation flip-flops from source to sink of carbon emissions, depending on the prevailing conditions.
Carbon pricing can be a powerful tool to combat climate change and reduce emissions, but it needs to be accompanied by improved regulations, clean technology subsidies and financing mechanisms.
Current greenhouse gas inventories in Canada only consider “managed” lands. This must change before we can truly understand the scale of Canada’s carbon emissions.
It might seem counterintuitive to suggest timber harvesting when the goal is to restore forests, but that gives landholders the economic incentive to protect and manage forests over time.
The deal is a global aspiration, not a legally binding agreement. But it should end the idea that burning carbon – in Australia and elsewhere – can continue on a significant scale beyond 2050.
Scope 3 emissions remain a crucial sticking point when it comes to strengthening climate reporting by corporations around the world.
‘Breath emissions’ are around 0.05% of the UK’s total methane emissions.
Garbage is decomposing in landfill sites across sub-Saharan Africa, releasing methane gas. If governments harnessed this as clean energy, Africa would avoid environmental damage worth US$6.7 billion.
Is reaching net zero emissions by 2050 enough to halt warming? One leading scientist says no.
As Climate Change and Energy Minister Chris Bowen lands in Dubai for COP28, Australia has announced an extra A$150 in climate finance with a focus on the Pacific region.
Banning public funding for overseas fossil fuel projects will boost Australia’s climate leadership. But can it take the next step and do it domestically?
Carbon capture and sequestration can play a role in limiting warming but the nuances of its application are far more complicated than just planting trees. Getting it wrong could make warming worse.
The Sunnylands Statement has set a powerful signal for COP28, however, it also highlights that more must be done in Dubai to define what it means to achieve ‘net zero.’
Releasing reflective particles into the upper atmosphere would help us tackle climate change – but it’s not without risk.
Record emissions are fast shrinking the remaining amount of carbon dioxide we can emit if we are to limit global warming. At current rates, we’ll use up the budget for a 1.5°C outcome in seven years.
Africa can check climate impact on health by taking 37 actions endorsed by environment ministers.
Electric arc furnaces can use up to 100% scrap steel as its raw material, resulting in a significant reduction in emissions.
A veteran of UN climate talks lays out the top themes and their sticking points, including concerns about the host country’s oil interests.
