There are calls from the backbench and elsewhere for the federal government to safeguard the future of coal. But do those calls make economic sense? A look at Queensland's energy landscape suggests not.

EU carbon prices held just above €15 for the second straight day on Tuesday after the day’s auction cleared relatively strongly and despite analyst warnings that the recent rally may have petered out.

This government’s decision to create more pollution at Heathrow (Report, 26 June) while simultaneously rejecting tidal power in Swansea Bay (Report, 26 June) shows it has no strategy for tackling climate change.

Although aviation only contributes about 2% of global emissions of carbon dioxide, it accounts for over 6% of global warming due the effects of other greenhouse gases and vapour trails. The upcoming report by the UK Committee on Climate Change shows that a third runway will increase CO2 emissions from air travel from 37 to 43 million tonnes per annum. But since our overall carbon budget will have fallen by 2030 to 344 million tonnes, the contribution from aviation will have jumped from 6.5% to 12.5% of the UK’s carbon emissions. In other words, a third runway is incompatible with the UK’s climate commitments, and things will only get worse post-Brexit.

The EU ETS has witnessed a dramatic change over the past year as carbon prices have quadrupled, the market has attracted new participants, and the developments have given confidence to existing participants that the world’s biggest carbon market will remain the EU’s main climate policy tool.

A new study says that alternatives to palm oil could make matters worse for endangered species.

Speculative buying in excess of 160 million tonnes has likely helped EU carbon prices double in value over the first half of the year, analysts said.

The strange weather phenomenon was spotted in Powys, as temperatures soared across Wales.

The deforestation it causes is decimating species such as orangutans and tigers - but the alternatives could be worse, finds authoritative report

It is consumed daily by billions of people but palm oil is “disastrous” for wildlife such as orangutans and tigers, according to an authoritative new report. However, the analysis warns that alternatives are likely to drive biodiversity losses elsewhere, rather than halt them.

The analysis, from the International Union for the Conservation of Nature (IUCN), found that rainforest destruction caused by palm oil plantations damages more than 190 threatened species on the IUCN’s red list, particularly in Indonesia and Malaysia. It also found that palm oil certified as “sustainable” is, so far, only marginally better in terms of preventing deforestation.

Sea level rises are not some distant threat. For many Americans they are very real. In an extract from her chilling new book, Rising, Elizabeth Rush details how the US coastline will be radically transformed in the coming years

In 1890, just over six thousand people lived in the damp lowlands of south Florida. Since then the wetlands that covered half the state have been largely drained, strip malls have replaced Seminole camps, and the population has increased a thousandfold. Over roughly the same amount of time the number of black college degree holders in the United States also increased a thousandfold, as did the speed at which we fly, the combined carbon emissions of the Middle East, and the entire population of Thailand.

About 60 of the region’s more than 6 million residents have gathered in the Cox Science Building at the University of Miami on a sunny Saturday morning in 2016 to hear Harold Wanless, or Hal, chair of the geology department, speak about sea level rise. “Only 7% of the heat being trapped by greenhouse gases is stored in the atmosphere,” Hal begins. “Do you know where the other 93% lives?”

New Zealand carbon allowances rose to four-week highs on Tuesday as the emergence of more buyers continued to push prices up.

Japan has awarded small grants to 17 projects that aim to cut greenhouse gas emissions and generate carbon credits under its Joint Crediting Mechanism (JCM).

A national container deposit scheme should be established in response to the recycling crisis, the report says

A Senate inquiry into Australia’s recycling crisis has recommended that all single-use plastics – which could potentially include takeaway containers, chip packets and coffee cups with plastic linings – be banned by 2023.

The wide-ranging report also recommends the establishment of a national container deposit scheme as a response to an unfolding crisis in Australian recycling that forced some councils to tip their recycling into landfill.

Representatives for major Australian business groups on Tuesday met with Coalition MPs to urge them to approve the National Energy Guarantee (NEG).

Leaders from the business community met Coalition MPs today in Canberra to explain the policy.

The Commons votes in favour of controversial plans for a third runway by 415 votes to 119.

First formal study into their impact finds that boroughs with the schemes have boosted walking and cycling rates

The so-called mini-Holland schemes – much-debated changes to boost cycling and walking in outer London boroughs – have done precisely that, according to the first formal study into their impact.

The research found that after one year, people living in parts of such boroughs were, on average, walking and cycling for 41 minutes a week more than those living in comparable areas.

Four councils back move, claiming proposal will not survive ‘independent, lawful and rational’ scrutiny

The transport secretary, Chris Grayling, is facing a fresh headache over Heathrow as a group of councils confirmed they were planning legal action against expansion, just hours after MPs voted overwhelmingly to back a third runway.

In an embarrassing blow for Theresa May, Conservative-run Windsor and Maidenhead, the prime minister’s own local council, suggested after Monday night’s vote that it was seriously considering joining the judicial review.

After a mysterious ‘mass mortality event’ turned ochre stars to goo, experts say rapid evolution may have saved the creatures

Five years after a mysterious virus wiped out millions of starfish off the western coast of North America, causing them to lose legs, dissolve into fleshy goo and taking various species to the brink of disappearance, scientists have announced a remarkable reversal.

Allendale, Northumberland: Growing abundantly along motorways, these pristine white flowers with their yellow centres have an endearing simplicity, like a child’s drawing

Driving north from Newcastle up the A1 there’s an upside to the slowing traffic. It’s an opportunity to look at the high embankments on either side that are crowded with oxeye daisies, Leucanthemum vulgare. Growing abundantly along motorways, these pristine white flowers with their yellow centres have an endearing simplicity, like a child’s drawing. Mixed among them I can see the yellow of buttercup, mauve of vetch, sharp pink of campion and isolated patches of red clover. Lower down, near the gritty edges of the road, are canary-yellow sprawls of bird’s foot trefoil, colours that have mostly been banished from farmland.

I grow all those wildflowers in my garden. All have nectar for bees, butterflies and hoverflies. The golden centre of the daisy head is not one flower but many, a composite of tiny disc florets, each containing food for insects. A grass path curves through my small perennial meadow, where chimney sweeper moths flicker between umbels of pignut and ragged robin. As I pause there in the evening light, there’s a delicacy to the planting with its fine grasses and small bursts of colour. On tall stems, the oxeye daisies glow as the sun drops behind the wood.

"Are you prepared to build or subsidise a new coal-fired power station?" Energy minister Josh Frydenberg was asked it a thousand times. And a thousand times he didn't answer it.
