Cattle are major producers of methane, a potent greenhouse gas. But there are methods that can reduce their climate impact – if ranchers have incentive to use them.
The US, a minor liquefied natural gas supplier a decade ago, now is the world’s top source. That’s good for energy security, but bad for Earth’s climate. An energy scholar explains the trade-offs.
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.
Food systems are increasingly disrupted by climate disasters, while also being a major contributor to climate change. World leaders at COP28 vowed to do something about it.
For Australia to shift to a net zero economy, its big polluters need to cut emissions. A get-out clause buried in the policy makes it unlikely that they will, and the result will be devastating.
The Biden administration directed agencies to consider the cost of greenhouse gas emissions in their future purchasing and budget decisions. An example shows just how much is at stake.
A new report spans more than 300 peer-reviewed studies to present a comprehensive summary of the risks the industry creates for people’s health and wellbeing, as well as for the planet.
Sydney’s 14 wastewater treatment plants could be modified to also accept food waste, research shows. The ‘anaerobic digestion’ process would produce energy as well as nutrients for reuse.
Regulating greenhouse gas emissions is an important part of Canada’s strategy to achieve net-zero emissions by 2050. However, a newly published study illustrates why enforcing regulation is key.
When food scraps and garden clippings are sent to landfill, it’s not just a waste of nutrients and water. The rotting organic matter trapped in landfill produces methane, a potent greenhouse gas.
Domestic use of natural gas is a minimal contributor to overall greenhouse emissions. There should be no rush to ban it before better, cheaper options are in place.
