A proposed mangrove methodology under Taiwan's voluntary carbon scheme has met with criticism from scholars and environmental groups, amid concerns over its potential negative impacts and exaggerated carbon sequestration benefit.

The whale was seen following the boat as it approached Bundeena wharf on Monday, a sighting the ferry company manager, Christine Hack, called 'very rare'. Dr Vanessa Pirotta, a wildlife scientist at Macquarie University, said she and other experts had identified the creature as likely to be a juvenile Antarctic minke whale, and that spotting one in Sydney’s warm waters was very unusual

Paris has made initial suggestions for reforming the EU’s Carbon Border Adjustment Mechanism (CBAM) and is planning to gather further input in the coming weeks with a view to preventing carbon leakage – or relocation of industries abroad to avoid the EU’s CO2 pricing policies.

Scientists unsure what prompted juvenile whale to leave icy southern waters for warmer shallows, but ‘it may be a case of mis-navigation’

Exclusive: Chemical in treatment for pet fleas and ticks is found in nests of blue and great tits, killing chicks

Songbird chicks are being killed by high levels of pesticides in the pet fur used by their parents to line their nests, a study has found.

Researchers surveying nests for the harmful chemical found in pet flea treatments found that it was present in every single nest. The scientists from the University of Sussex are now calling for the government to urgently reassess the environmental risk of pesticides used in flea and tick treatments and consider restricting their use.

Clean energy additions and slower industrial power demand growth may lead to a fall in China's emissions from the power sector this year, even though government's stimulus efforts could complicate the emissions outlook, according to a report published Monday.

The Grampians globe-pea, a critically endangered wiry shrub, had finished flowering and was fruiting when fires tore through its home in the Grampians national park, in western Victoria. The spiny plant with vibrant orange and yellow flowers is extremely rare and restricted to a handful of sites, including areas within the 76,000 hectares that burned over December and January.

Finding the globe-pea will be a priority when a plant rescue mission led by Royal Botanic Gardens Victoria heads to the Grampians to search for survivors and signs of life amid the charred landscape.

Achieving net-zero emissions by 2050 is humanity’s only hope of achieving climate security. It’s time to think deeply about our chances of getting there.

Private developers offer politicians a simple solution for bulldozing through this crisis – build more. But it won’t work

Build baby, build. That’s about the intellectual limit of the government’s housing strategy. Millions are under-housed, so let’s “bulldoze” the planning system and build more homes. But it’s not nearly so simple.

As soon as anyone challenges the policy, the government brands them a nimby – another of the crude truncations that pass for debate on this issue: nimbys versus yimbys. So before I go further, let me state that I want to see lots of new social and genuinely affordable housing built as part of a massive programme to solve the worst housing crisis of any wealthy country. I’ve been making similar calls for years, not least in the report I co-authored for the Labour party in 2019: Land for the Many. I oppose Labour’s current approach for a different reason. It will fail.

Ahead of a major speech on economic growth this coming week, the chancellor made the case for Heathrow expansion and said there was “huge investment” in more sustainable aviation.

In two actions, migrant workers claim exploitation while farmers demonstrate against inheritance tax plan

This is a tale of two countrysides. One was featured prominently on Saturday by broadcasters as farmers held demonstrations throughout the UK against inheritance tax plans they believe will cripple family farms.

A smaller protest staged a day earlier outside the Home Office received almost no attention. A small band of fruit and vegetable pickers, mainly from Latin America, were highlighting their battle against what they call the exploitation of migrant workers.

Environmentalists say new course could be delayed until 2030 because it is viewed as Conservative party initiative

Leading environmentalists have called on the government to introduce a natural history GCSE immediately, amid fears it could be postponed until 2030.

The previous Conservative administration had supported creating the GCSE, which would teach pupils how to observe, identify and classify plants and animals.

As chancellor Rachel Reeves’ plan to expand London airports gains traction, the party is accused of back-pedalling on its green commitments

Labour is being warned it is hurtling towards a “powder keg” confrontation with environmentalists, green groups and a swathe of its own supporters in the next few weeks, amid its claims that “blockers” are standing in the way of economic growth.

A flurry of pro-growth measures have been announced by ministers in recent days as part of a government fightback against claims that the economy is stalling.

India's Bureau of Energy Efficiency (BEE) has released 12 draft methodologies to be adopted for its voluntary offset mechanism under the country's Carbon Credit Trading Scheme (CCTS) and has opened them for public consultation, it announced this week.

The chancellor’s attempt to get rich landowners to pay their fair share was correct in principle. But this measure has missed the mark

Rachel Reeves needs to rid herself of ­troublesome farmers. It’s become obvious, if it wasn’t at the time of the budget, that they are not going to go away.

Their shouts of protest are getting louder and the petition against proposals to tax inherited farms is growing longer.

University of Cambridge research suggests living collections have collectively reached peak capacity

Botanic gardens around the world are failing to conserve the rarest and most threatened species growing in their living collections because they are running out of space, according to research from the University of Cambridge.

Researchers analysed a century’s worth of records from 50 botanic gardens and arboreta, collectively growing half-a-million plants, to see how the world’s living plant collections have changed since 1921.
