In major cities around the world, dockless scooters and bikes are everywhere, yet the companies themselves are often breathtakingly short-lived. Basic economic concepts give us clues why.
A knobbed hornbill in tropical forest, Sulawesi, Indonesia.
Instead of boycotting palm oil, source it from pastureland and not recently logged forests.
If the cement industry were a country, it would be the
third-largest emitter of CO₂ in the world.
The cement needed to make concrete – the most widely used man-made material – is a major source of global emissions. Researchers are working on a green replacement that could transform the sector.
Nuclear power will likely remain part of the global energy mix.
Recent debates about the future of nuclear power in Australia make much of the potential of the next generation of reactors.
Turning a street tree into timber is much more respectful and useful than mulching it all.
City trees are often short-lived and many others get cut down in their prime. Turning them into mulch both wastes timber and releases stored carbon. A wood rescue program creates a more fitting legacy.
Wales is one small country with big carbon targets but that still needs the policies to deliver them.
The future of zero-carbon transport starts today. First stop, Britain's railways.
Old and new in Milton Keynes, UK.
Developers pay more tax to refurbish than demolish and rebuild – but there's a very easy fix.
Carbon productivity is the measure that matters, but we are hung up on the productivity of our workers.
Labor productivity doesn't matter as much as emissions productivity. Workers aren't a particularly finite resource.
Renewable energy being installed at a community in the Northern Territory. Researchers have predicted Australia’s emissions are set to fall, but warn the renewables deployment rate must continue.
Australia's renewables revolution proves that there's cause for hope in our emissions reduction goals. But we cannot rest on our laurels.

Despite voting to remain a member of an Australian coal lobby group, there are growing divisions between fossil fuel extractors and the larger energy industry.
The vast emissions caused by these individuals suggest that a very small share of humanity has a very significant role in global warming.
The fossil fuel industry plans to compensate for declining demand for gasoline by flooding the world with more plastic.

Carbon emissions from international air travel show no sign of abating. In the absence of a tax on jet fuel, are sail boats the best way to travel the world sustainably?
Australia’s major mining companies are significant contributors to global emissions.

Australia cannot distance itself from moral responsibility for emissions from exported fossil fuels.
Labour's next manifesto could be defined by a radical proposal for tackling climate change.
Had the EU eliminated all subsidies between 2010 and 2017, its emissions would have been 9% lower over the period and governments across the EU would have saved US$441 billion.
Research into low-carbon planes is underway, but we won’t see electric long-haul flights any time soon.

Unlike a car, you can't just stick a battery-powered engine in a plane and expect it to fly. Despite that, small planes might be the future of electric flight.
Shouting out loud.
Scientists from all over the world agree that the impacts of climate change will get worse, unless action is taken now.
The Port Kembla industrial area in NSW. Industry emissions can be cut by improving efficiency, shifting to electricity and closing old plants.
The UN has asked world leaders to bring concrete climate action plans to this week's summit - and Australia is likely to cop heavy criticism.
