Biofuels are heralded as a climate-friendly replacement of fossil fuels, but encouraging people to drive less and shift to other modes of transport would cut more emissions.

Ultra long-haul flights make it possible to go Sydney to London non-stop. But does the world need them, given they are more polluting and less efficient?
A new study finds that by 2030, less than one-third of the world’s major crop harvests will go directly to feed people.
Allowing the sale of gasoline that’s 15% ethanol year-round won’t have much impact on gas prices, but recent research shows that growing corn for fuel affects the climate – for the worse.
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 hidden costs of industrial food production include immense health and environmental impacts. These include millions of deaths, climate change, pollution and biodiversity loss.
How do we ensure solutions to climate change doesn’t make biodiversity loss worse? Fifty of the world’s leading researchers on biodiversity and climate have sought to answer this question.
Soot from aeroplane exhausts can linger in the atmosphere, seeding ice clouds which trap heat.
A complete switch to biofuels is neither feasible nor desirable, but they could replace some fossil fuels in transport and heating. If biofuels are produced from waste products, that’s even better.
Making biofuels from crops grown on land poses trade-offs between food and fuel. A new study looks offshore.
You can reduce your fuel consumption by 15-20% with improved driving habits alone – reducing emissions and saving money at the same time.
We analysed what the world’s top 58 airlines – such as American Airlines, British Airways and Qantas – are doing about climate change. Even the best airlines are not doing anywhere near enough.
We can’t decarbonise the whole transport sector with just batteries - sustainable fuels are essential.
Many current and former US military leaders call climate change a serious national security threat, but few of them mention the Defense Department’s big carbon footprint.
We don’t notice the plant species we’re losing, but we won’t be able to ignore the effect of their loss on our supply of food and medicine.
Jokowi’s re-election may put the global biodiversity at risk
Vehicles made before 2001 could suffer fuel system or engine damage if they’re run on E15.
Increased use of renewable energies could help curb climate change, but the water required for their production has dispossessed rural Guatemalans.
Natural gas is touted as a “bridging fuel” to displace coal while moving to a low-carbon economy. In New Zealand, this is shortsighted and could lead to stranded assets and hold back renewables.
Sun, wind, waste biomass, geothermal, tides and waves: all these energy sources in Sydney’s backyard add up to a zero-carbon energy solution for the city.
