Some Australian states have committed to 100% renewable energy targets, or even 200% renewable energy targets. But this doesn’t mean their electricity is, or will be, emissions free.
Cities around the world are reducing traffic speeds and improving access to local services and activities by public transport, cycling and walking. They are now reaping the many ‘slow city’ benefits.
The lead author of a new UN report on methane explains the findings and how oil and gas companies could be making money and saving the climate at the same time.
Growing weed indoors is not an environmentally friendly process. Climate controls create a lot of greenhouse gas emissions, and where the pot is produced has a huge influence on emission levels.

A person who exercises, attends sporting events as a spectator and takes their kids to the oval or swimming pool will create 935 kg of CO₂ per year if using their car.
Indonesia’s Peatland Restoration Agency is likely to have its tenure extended by four years. What has been achieved and what should the agency focus on for the next term?
Universities and the professions are changing in response to climate change. When will the advances in knowledge and practice we are already seeing prompt governments to act with the required urgency?
It reveals in alarming detail how gas emissions are cancelling out the gains won by Australia’s renewables boom, and uncovers misleading claims underpinning our gas-led economic recovery.
A building designed to be easily taken apart so the components can be reused is a model for much less wasteful construction. It reduces resource use and environmental impacts, and can be cheaper too.
Life cycle assessments of electric vehicles show that they cannot fully eliminate the greenhouse gas emissions of personal travel. We also need bikes, buses and trains to solve our climate problems.
Universities are vital hubs of research and teaching on climate change and, as big organisations, produce significant emissions themselves. They should therefore lead action to limit climate change.
The coronavirus pandemic caused the UN’s annual climate conference to be postponed by a year, but it was also responsible for a drop in carbon emissions. Is it enough and will it last?
