Growing ship numbers and reductions in the industry’s total emissions add up to big emission cuts per ship – as much as 60% by 2030 and 91% by 2040. The days of fossil-fuelled ships are now numbered.

Can planting trees help us solve the climate crisis? Probably, but to what extent?
A new study estimates a reduction in emissions of only 35-45% of pre-COVID levels by 2050. Lighter vehicles and faster uptake of electric vehicles can dramatically improve progress towards net zero.

The strong trade relationship with the EU means policy changes like the border tax may have disproportionately significant effects on African economies.
Drought in Europe, dwindling Arctic sea ice, a slow start to the Indian monsoon – unusually hot ocean temperatures can disrupt climate patterns around the world, as an ocean scientist explains.
Marine life known as zooplankton might be the biggest problem with getting carbon cycling right in climate models. The potential variations in carbon uptake are greater than global transport emissions.
When Peter Singer first published Animal Liberation in 1975, he wasn’t aware of climate change. But the new book, Animal Liberation Now, argues eating plants will reduce greenhouse gas emissions.
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.
If greenhouse gas emissions continue at a high rate, breadbaskets of Europe and North America will see a 50% chance of a flash drought each year by the end of this century.
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.
Mangroves and salt marshes pump out methane – but soak up carbon dioxide. Overall, the world’s coasts are a net greenhouse sink – and we must preserve them
There’s a 98% chance of a record hot year by 2028, and a 66% chance of exceeding the 1.5°C threshold for at least that year, according to the latest World Meteorological Organization update.
Even if the industry could make the shift, there’s not enough land or renewable energy potential on Earth to produce all the sustainable fuels airlines need.
After the Supreme Court overturned the Obama administration’s strategy for reducing power plant carbon emissions in 2022, the Biden administration is taking a narrower but still ambitious approach.
Record numbers of visitors are flocking to blockbuster exhibitions. Behind all the excitement, there are difficult questions over how to address their carbon footprint.
