‘People think they’ll smell but they don’t’: building homes from mushroom waste and weeds

Posted on by

A sustainable project aims to repurpose encroacher bush to create building blocks to solve Namibia’s housing crisis

“People think the house would smell because the blocks are made of all-natural products, but it doesn’t smell,” says Kristine Haukongo. “Sometimes, there is a small touch of wood, but otherwise it’s completely odourless.”

Haukongo is the senior cultivator at the research group MycoHab and her job is pretty unusual. She grows oyster mushrooms on chopped-down invasive weeds before the waste is turned into large, solid brown slabs – mycoblocks – that will be used, it’s hoped, to build Namibian homes.

Glass Pharms hope its approach could show the way for all kinds of energy-intensive horticulture in the UK

For 26 years, Olivier Dehon worked in the corporate sector, ending up as chief financial officer for Xerox in the UK and Ireland before retiring four years ago. Last month he delivered his first consignment of high-strength cannabis.

Dehon’s dope is legal and above board, produced to supply the UK’s burgeoning market for medical cannabis on prescription. What’s more, Dehon and his colleagues believe it is the first carbon-neutral indoor weed grown anywhere in the world.

Emissions from Israel’s war in Gaza have ‘immense’ effect on climate catastrophe

Exclusive: First months of conflict produced more planet-warming gases than 20 climate-vulnerable nations do in a year, study shows

The climate costs of war and militaries can no longer be ignored

The planet-warming emissions generated during the first two months of the war in Gaza were greater than the annual carbon footprint of more than 20 of the world’s most climate-vulnerable nations, new research reveals.

The vast majority (99%) of the 281,000 metric tonnes of carbon dioxide (CO2 equivalent) estimated to have been generated in the first 60 days following the 7 October Hamas attack can be attributed to Israel’s aerial bombardment and ground invasion of Gaza, according to a first-of-its-kind analysis by researchers in the UK and US.

World leaders will reconvene in Abu Dhabi before UAE’s Cop28 after talks broke down two weeks ago

Governments will meet this weekend for a last-ditch attempt to bridge deep divisions between rich and poor countries over how to get money to vulnerable people afflicted by climate disaster.

Talks over funds for “loss and damage”, which refers to the rescue and rehabilitation of countries and communities experiencing the effects of extreme weather, started in March but broke down in rancour two weeks ago.

M&S says ‘short-sighted act of self-sabotage’ leaves no choice but to review position on UK’s premier shopping street

Marks & Spencer has been refused permission to demolish and rebuild its main store on Oxford Street in the West End of London in a win for campaigners concerned about the carbon footprint of redevelopment.

The Department for Levelling Up, Housing and Communities confirmed that Michael Gove, the secretary of state, disagreed with the recommendation from inspectors to approve the plans and had “decided to refuse permission”.

Norway’s sovereign wealth titan threatens to vote against boards on firms it holds investments with over lax climate and social targets

Norway’s sovereign wealth fund, the world’s single largest investor, has warned company directors it will vote against their re-election to the board if they don’t up their game on tackling the climate crisis, human rights abuses and boardroom diversity.

Carine Smith Ihenacho, chief governance and compliance officer of Norges Bank Investment Management, which manages more than 13tn Norwegian kroner (£1tn) on behalf of the Norwegian people, said the fund was preparing to vote against the re-election of at least 80 company boards for failing to set or hit environmental or social targets.

Human activity and drought ‘degrading more than a third of Amazon rainforest’

Fires, land conversion, logging and water shortages have weakened resilience of 2.5m sq km of forest, says study

Human activity and drought may have degraded more than a third of the Amazon rainforest, double the previous estimate, according to a study that heightens concerns that the globally important ecosystem is slipping towards a point of no return.

Fires, land conversion, logging and water shortages, have weakened the resilience of up to 2.5m sq km of the forest, an area 10 times the size of the UK. This area is now drier, more flammable and more vulnerable than before, prompting the authors to warn of “megafires” in the future.

Superyacht sales surge prompts fresh calls for curbs on their emissions

Posted on by

Campaigners say a superyacht can produce 1,500 times more carbon than a typical family car, and the polluters should pay

The rising fortunes of the world’s billionaires during the pandemic helped fuel a record £5.3bn in superyacht sales last year, prompting calls for new curbs on their emissions.

New figures reveal that 887 superyachts were sold in 2021, an increase of more than 75% compared with the previous year. Yachting brokers say some of the demand has been from wealthy clients seeking a secure refuge from the pandemic.

Is remote working better for the environment? Not necessarily

Companies have a rare moment to reset working models. But climate calculations of remote v office work are complex

Stacy Kauk was finalizing Shopify’s 2019 sustainability report when the pandemic forced the company into remote work.

“I kind of stopped in my footsteps and went, ‘Uh oh, what’s going to happen if we’re closing our offices during Covid and staying remote in the long term? What does that mean for Shopify’s corporate carbon footprint?’” said Kauk, who directs the Canadian e-commerce company’s $5m annual sustainability fund.

‘The Queen’s bank’ Coutts joins the ranks of ethical brands

Despite chequered history the 329-year-old private bank has secured the sought-after B Corp status

Private bank Coutts will offer carbon credits and green mortgages to its ultra-wealthy clients after becoming one of the largest UK banking brands to secure B Corp status.

Coutts, known as the Queen’s bank for having served every member of the royal family since George IV, is trying to bolster its environmental and social reputation after being dogged by a series of scandals in recent years, including sexual harassment allegations against its former star banker Harry Keogh, who was sacked in 2018. The bank was also fined by Swiss regulators in 2017 over alleged money laundering and for illegally profiting from transactions associated with the 1MDB scandal.

Rewild to mitigate the climate crisis, urge leading scientists

Restoring degraded natural lands highly effective for carbon storage and avoiding species extinctions

Restoring natural landscapes damaged by human exploitation can be one of the most effective and cheapest ways to combat the climate crisis while also boosting dwindling wildlife populations, a scientific study finds.

If a third of the planet’s most degraded areas were restored, and protection was thrown around areas still in good condition, that would store carbon equating to half of all human caused greenhouse gas emissions since the industrial revolution.

Brazil, India and China singled out in UN talks as acting to block agreement on article 6 of Paris agreement

Poor countries have accused a handful of richer nations of holding up progress on tackling the climate crisis at UN talks in Madrid, as demonstrators and activists vented their frustration in the final hours of two weeks of negotiations.

The talks dragged on with negotiators battling into the early hours of Saturday to salvage a result, as governments wrangled over the details of a seemingly arcane issue: carbon markets, governed by a provision of the 2015 Paris agreement known as article 6.

No fly zone: I didn’t catch a plane for a year and saved 19 tonnes of Co2

A year without air travel taught me the path to carbon neutral won’t be easy, but I learned I could inspire others to act

What is the single thing that you could do that would most reduce your carbon footprint? Take your bike to work rather than your car? Dig up your lawn for a vegetable garden? For me, an academic scientist living and working in Auckland, New Zealand, I reasoned that the most significant thing I could do was to stop flying.

In 2017 I flew 84,000km. I made twenty day trips to Wellington, New Zealand’s capital city. I travelled to the United Kingdom, Canada, and Australia to attend conferences and work on joint projects with other scientists. All of this made me accountable for around 19 tonnes of carbon dioxide that year, nearly three times that of the average Kiwi.

Inside Copenhagen’s race to be the first carbon-neutral city

Posted on by

Green growth and ‘hedonistic sustainability’ have helped keep the public on board as the Danish capital seeks to reach its goal by 2025 – and so far it’s all going according to plan

“We call it hedonistic sustainability,” says Jacob Simonsen of the decision to put an artificial ski slope on the roof of the £485m Amager Resource Centre (Arc), Copenhagen’s cutting-edge new waste-to-energy power plant. “It’s not just good for the environment, it’s good for life.”

Skiing is just one of the activities that Simonsen, Arc’s chief executive, and Bjarke Ingels, its lead architect, hope will enhance the latest jewel in Copenhagen’s sustainability crown. The incinerator building also incorporates hiking and running trails, a street fitness gym and the world’s highest outdoor climbing wall, an 85-metre “natural mountain” complete with overhangs that rises the full height of the main structure.

Next generation must keep their own carbon levels at a fraction of their grandparents’ in order to prevent catastrophe

Children born today will have to live their lives with drastically smaller carbon footprints than their grandparents if climate change is to be controlled.

Fast, deep cuts in global emissions from energy, transport and food are needed to keep temperature rises in check and an analysis has shown this means the new generation will have lifetime carbon budgets almost 90% lower than someone born in 1950.
