‘Beccs’ faces lots of problems. A global switch away from meat could help address them.
Energy inequality must fall – and do so drastically – to maintain a safe climate.
Energy inequality will have to reduce substantially by 2050 to maintain a safe climate and decent living standards for all.
Our research shows NZ’s potential to burn forestry waste and capture the emissions in geothermal wells. But we’ll need new partnerships between power generators, manufacturers and the forestry sector.
The roadmap predicts that by the 2030s, the sector could boost Australia’s annual GDP by around A$10 billion, create 26,200 jobs and reduce emissions by about 9%.

Removing carbon from the atmosphere is as much a social problem as a technical one.
Forests are not just carbon ‘warehouses’ they are extraordinary ecosystems supporting a diverse range of birds, animals and plants.
Carbon has overshadowed forests in climate policies, leading to practices that appear green but actually harm forests.

Making biofuels from crops grown on land poses trade-offs between food and fuel. A new study looks offshore.
Zero emission? Carbon neutral? Carbon negative? What does it mean to achieve ‘net-zero’ emissions?
The Paris Agreement on climate change, signed on Dec. 12, 2015, by almost 200 states, was hailed as the turning point to keep global warming in check. Progress, however, has been insufficient.
The Paris Agreement set countries on a path to limit global warming. Five years on, some progress has been made, but not enough. Decarbonizing the economy will take leadership and imagination.
Indonesia can tap into its microorganism resources for potential renewable energy development.

Energy Minister Angus Taylor is this week expected to release the government’s first Low Emissions Technology Statement. It’s likely to include ways to remove CO₂ from the air – but do they work?

Ireland needs to stop burning peat, and wood from down under presents a surprising sustainability dilemma.

In the eastern reaches of Siberia, scientists discovered plants with exceptional cold tolerance that could be the key to sustainable bioenergy production.

Vehicles made before 2001 could suffer fuel system or engine damage if they’re run on E15.
Bioenergy Carbon Capture and Sequestration, known as BECCS, is one of the technologies we may need to limit warming to 1.5 degrees.
Delays on climate action to reduce emissions means that we may have to consider technologies that strip carbon dioxide from the atmosphere. But that will come at a cost.

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.

New research calculates the huge cost of ‘negative emissions’ technologies that will be required to avoid dangerous climate change.
An excavator clears land for a palm oil plantation in southern Sierra Leone for a Lichtenstein-based a company. Such projects are criticised by some as ‘land grabs’.
International development banks are supposed to ensure adherence to human rights in the projects they fund. Instead, their practices provide fertile ground for human rights abuses.

The future of two key energy policies – the EPA’s Clean Power Plan and Renewable Fuel Standard – will decide whether bioenergy will continue to grow in US or not.

The government has issued a draft direction to the Clean Energy Finance Corporation to invest in “emerging” clean energy such as bioenergy. But what are the prospects for bioenergy?
