The world is facing one of the century’s biggest challenges: How to nutritiously feed the growing population, address climate change and not destroy the ecosystems on which we all depend for life.
The US has required motor fuels to contain 10% biofuels since 2005. As this program nears a key milestone in 2022, farm advocates want to expand it while critics want to pare it back or repeal it.
The goal of carbon neutrality changes everything. Canada can no longer limit itself to solutions that partially reduce emissions here and there. The chosen solution must be zero emissions.
Bill C-12 is a step in the right direction, but its not enough to meet Canada’s goal for a decarbonized economy.
Attempts to formalise charcoal production have been largely unsuccessful.
David Littleproud on The Nationals and net zero.
Michelle Grattan discusses the National party's feelings towards a 2050 carbon neutral goal with deputy leader David Littleproud.
Zero emission? Carbon neutral? Carbon negative? What does it mean to achieve ‘net-zero’ emissions?
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.
Energy efficiency and electrification should lead the effort to decarbonise society, not hydrogen.
Energy companies are marketing a new fuel: ‘renewable’ natural gas. But it’s not the same from a climate change perspective as wind or solar energy.
Social tipping interventions have the potential to pave the way for rapid change and avert climate change.
The Drax biomass plant in Yorkshire is the first in the world to pioneer carbon capture and some specialists see it as it has a bright future. But hold the rosy headlines.
Deriving fuel from trees costs more than wind and solar power and it emits more carbon than coal. There are many heated debates about this kind of energy, known as forest or woody biomass.
The pioneering legislation is ten years old – and the latest science means it now does not go far enough.
Greater Manchester wants to be “zero carbon”. But this sort of target raises some important questions.
Cities all over the world are facing growing challenges to provide clean, reliable water. And many of the fixes, such as desalination plants, have a huge carbon footprint.
As part of its 100-day priority plan, New Zealand’s new government has pledged to set a target of carbon neutrality by 2050, which means phasing out fossil fuels and products that burn them.
A new analysis by ClimateWorks Australia says that the electricity sector needs to do far more to cut its carbon emissions than will be delivered by current policies.
The University of California intends to be carbon-neutral by 2025 by implementing existing technologies and focusing on public education. Is this a model for decarbonizing at large scale?
