Fifteen years ago electric power generation was the largest source of US greenhouse gas emissions. Now the power sector is leading the shift to a clean energy economy.

Scientists need to know how much we can rely on the land to offset our emissions.
Peatlands store more soil carbon than any other terrestrial ecosystem, including tropical forests. But they have been heavily exploited and damaged. Now, scientists are working to restore them.
The Earth should be safe (and habitable) for a few billions of years, but we still need to worry about the impact now of just a few degrees of global warming.
Discord and doubt are the last things the world needs at this critical moment.
A transcript of episode 7 of The Conversation Weekly pocast, including an extra from Don’t Call Me Resilient on the treatment of migrant workers in Canada.
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.
The global pandemic caused an unprecedented drop in global emissions. But this is likely to rebound as economies start to recover.
Economic recovery and carbon neutrality are linked. Both depend on the ocean’s ability to continue to regulate climate.
Bitcoin is attracting attention from big buyers like Tesla. But don’t be fooled – it’s still a disaster for the climate.
No-one says reducing emissions from the agriculture sector will be easy. But it must be done, or farmers will suffer the most.
The presence of water on the Earth’s surface is the result of a subtle balance between different mechanisms in the atmosphere and below the surface.
Machines using giant fans and filters can literally suck carbon dioxide out of the air. Sounds great – but the technology faces many challenges.
Several countries have made pledges to reduce their greenhouse gas emissions to zero by mid-century. But new research finds the remaining carbon budget will be depleted before we get there.
In the ocean, phytoplankton helped by diazotrophs play an outstanding role in withdrawing CO₂ from the atmosphere. But climate change is disturbing this delicate balance.
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.
The pandemic, along with other recent trends such as the shift towards clean energy, have placed us at a crossroad: the choices we make today can change the course of global emissions.
Our new study shows that cutting emissions now will bring benefits sooner than expected.
The Climate Change Committee has laid out a road map for net zero emissions that the UK government could follow.
Black Friday sales reveal fast fashion extremes. But how does it affect the planet?
