A new biodegradable bamboo plastic could replace conventional plastics, offering a fully biodegradable alternative that is durable, recyclable, and easy to manufacture at scale.

Chinese researchers have developed a biodegradable bamboo plastic that not only rivals but surpasses traditional petroleum-based plastics in strength and thermal stability while decomposing naturally within 50 days. The breakthrough, published in Nature Communications in October 2025, could revolutionize manufacturing by offering a renewable, recyclable, and high-performance alternative for industries such as automotive and infrastructure.

When Angola’s Laúca hydropower dam began operating on the Kwanza River, it was widely presented as a milestone moment in Angola’s green energy grid development. Built by Chinese contractors and financed largely through Chinese loans, the project added more than 2,000 megawatts of capacity to the national grid and was framed as a key step toward cleaner energy.

In official state-sponsored Chinese narratives, projects like Laúca are frequently cited as examples of “green cooperation” in China–Africa relations. Government portals linked to the Belt and Road Initiative (BRI), China’s international development and infrastructure connectivity project, describe overseas hydropower as a low-carbon solution that supports both foreign development and international climate goals.

Yet in Angola, journalists and civil society groups are telling a more complicated story — one shaped not only by megawatts and emissions, but by debt, transparency, and questions around who ultimately benefits from large-scale infrastructure projects.

[...]

In [Chinese] framing, large hydropower projects are positioned not only as development infrastructure but also as climate-aligned investments supporting global energy transition goals.

[...]

Angola is today one of China’s largest borrowers in Africa. The Chinese government and its state media have proudly touted this fact for years. Data compiled by the Global Development Policy Center at Boston University show that the country has received more than USD 40 billion in Chinese loans, much of it tied to oil-backed repayment arrangements.

While Chinese policy researchers have framed resource-backed lending as a stabilizing tool during Angola’s post-war reconstruction, many subsequent reports by international media and independent researchers have highlighted how heavy reliance on oil-backed debt has left the country exposed during downturns.

[...]

[One report] noted that Angola is “saddled with high external debt to various creditors, including oil-backed loans from China,” and has increasingly turned to complicated financing arrangements as access to conventional borrowing narrows. The same report also warned that Angola currently has no financing program with the International Monetary Fund, underscoring the limited policy space available when oil revenues fall.

[...]

When prices [for oil] fell after 2014, debt servicing absorbed a growing share of public revenue, narrowing fiscal space for health, education, and climate adaptation.

Debt sustainability assessments by the International Monetary Fund and the African Development Bank continue to flag Angola’s vulnerability, noting that high repayment obligations constrain public investment.

[...]

Sustainability is not measured only in megawatts or emissions avoided. It also depends on transparency, debt sustainability, and whether projects expand — or constrain — a country’s development goals.

Angola’s experience suggests that clean energy can still come with high political and economic costs, even when framed as green cooperation. At the same time, China’s growing footprint in overseas finance has sparked alarm among analysts who warn that countries such as Angola risk sliding deeper into debt dependency. Under the banner of green finance, Chinese lending is increasingly presented as a superior alternative to Western aid — a message that features prominently in Chinese state media and has found a receptive audience in parts of Africa, both at the governmental level and among the public.

A key component of the study [to be conducted in Romania] is the characterisation of low-conflict sites—areas with minimal risk to biodiversity and communities and which meet essential technical criteria for renewable energy development. These areas are broader than the RAAs defined in Directive (EU) 2023/2413, and while not all low-conflict sites will become RAAs, mapping them nationwide will support responsible renewable deployment both within and beyond designated acceleration zones.

...

Beyond identifying low-conflict areas for clean energy development, the study will serve as a dialogue platform bringing together national and local authorities, grid operators, energy associations, academia and civil society. This collaborative space will help address challenges, share perspectives and strengthen informed decision-making in shaping Romania’s renewable energy future.

  • The European Union plans to expand its Carbon Border Adjustment Mechanism to some assembled goods such as cars and washing machines to help close loopholes.
  • The EU introduced CBAM to safeguard its industry during an ambitious shift to net zero by 2050 and prompt other parts of the world to make their output greener.
  • The EU will propose measures to extend the levy to selected steel and aluminium-intensive downstream products, and will also unveil a proposal on how to support its own exporters via a new fund.

...

The European Union plans to expand an incoming emissions charge on imported goods as part of efforts to strengthen a flagship climate policy that’s aimed at protecting the bloc’s industries during the green shift.

The EU has pressed ahead with its Carbon Border Adjustment Mechanism — which covers six emissions-intensive sectors — despite criticism from trading partners from the US to China. On Wednesday, it plans to propose measures to extend the levy to some assembled goods such as cars and washing machines to help close loopholes, according to a draft.

...

The EU introduced CBAM to safeguard its industry during an ambitious shift to net zero by 2050 and prompt other parts of the world to make their output greener. The idea is that carbon-intensive sectors forced to comply with the bloc’s world-leading climate laws won’t face unfair competition from producers operating in nations with weaker rules. It comes amid concerns that Europe is deindustrializing under the strain of high energy prices and the green transition.

“The overall objective of the legislative proposal is to strengthen the effectiveness of CBAM, thus reducing greenhouse gas emissions and fighting climate change globally,” the EU says in the draft proposal, which is still subject to change. “This proposal will extend the scope of CBAM to selected steel and aluminium-intensive downstream products.”

...

As of January this year, dozens of carbon-trading systems were in force globally, covering almost a fifth of global emissions, according to a report by non-profit organization IETA. Under EU rules, the fee importers will need to pay could be at least partially waived if a carbon levy has already been paid in the country where the goods were produced.

“The CBAM is deeply unpopular among major exporters to the EU, but it has already proven to be effective in pushing reticent countries toward building or expanding carbon-pricing efforts,” said Henry Lush, a carbon analyst at consultants Veyt.

...

The European Commission on Wednesday will also unveil a proposal on how to support its own exporters via a new fund filled with a quarter of the proceeds collected from the levy over the next two years, according to a draft seen by Bloomberg. In addition, it will present detailed rules on calculating fees that importers will have to pay at the border, and measures to prevent circumvention.

The fees companies will have to pay will largely depend on the so-called default values, which will effectively set a price list for emissions when importers can’t provide verified, installation-specific data at the border, according to Robert Jeszke, head of Poland’s emissions management authority.

“In the early years, the most immediate behavioral effect is likely to be improved monitoring and verified reporting, rather than instant deep decarbonization across the board,” he said. “But CBAM’s financial materiality will rise over time.”

An atmospheric phenomenon occurring over much of California was unmistakable in satellite imagery in late autumn 2025. Fog stretching some 400 miles (640 kilometers) across the state's Central Valley appeared day after day for more than two weeks in late November and early December. Known as tule (TOO-lee) fog, named after a sedge that grows in the area's marshes, these low clouds tend to form in the valley in colder months when winds are light and soils are moist.

China’s dominance in the renewable energy supply chain—especially in rare earth minerals, copper and lithium processing—has led to massive industrial expansion in Tibet. While promoted internationally as sustainable climate action, many projects have instead resulted in water contamination, ecosystem collapse, cultural displacement, and intensified political repression.

“Under the guise of green energy development, Tibet is being reshaped to fuel China’s economic and geopolitical ambitions,” said Tempa Gyaltsen Zamlha, Deputy Director of the Tibet Policy Institute, in his welcome address. “These mines and mega-dams are marketed as climate-friendly, but they have devastated Tibet’s rivers, grasslands, wildlife habitats, and traditional communities.”

The Tibetan Plateau, often called the Third Pole, contains the world’s largest reserve of freshwater outside the polar regions. Its rivers support nearly 1.9 billion people across Asia. Yet, scientists have warned that the plateau is warming at nearly twice the global average, accelerating glacial melt and causing irreversible environmental instability.

The world’s biggest carbon polluter is expected to keep total emissions flat in 2025 despite rising energy demand – a sign that clean power may, for the first time, fully offset the growth in electricity consumption, the analysis by the Centre for Research on Energy and Clean Air (CREA) showed.

The country’s emissions only rose by 0.6% in 2024, a significantly slower pace of growth than the previous year, according to official Chinese government data published on Thursday.

But the Finland-based research group cautioned that a “concerning” policy environment for the next few years increased the risk of an emissions rebound. It added that China was also set to miss its key target for cutting carbon intensity – CO2 emissions per unit of gross domestic product – this year, meaning steeper reductions will be needed to hit its headline 2030 climate goal of slashing carbon intensity by 65%.

[...]

Record solar energy installations and strong growth in wind power capacity have increased the share of non-fossil fuel electricity this year, with emissions from the power sector set to decline for the first time since 2016, the report said. But that progress has been partially countered by the rapidly growing use of coal for the production of plastics and other chemical products, meaning overall emissions are expected to remain stable.

At the same time, experts have warned that China’s new pricing system for solar and wind projects risks slowing the clean energy boom. Under the new policy introduced last June, developers of new solar and wind power plants need to secure contracts with provincial authorities through competitive auctions, instead of being guaranteed a fixed price.

[...]

Coal power plants, on the other hand, are protected from this market-based system, relying instead on long-term power purchase agreements that lock in prices, Schäpe said, describing it as “unfair competition”.

China’s rapidly expanding coal power fleet is adding to the concerns. In 2025, the country has added the largest amount of coal-fired capacity since 2015, while progress on retiring older plants remains very slow, CREA’s report highlighted.

This runs contrary to a pledge made by President Xi Jinping in 2021 to “strictly control” new coal power projects. That commitment was omitted from Beijing’s updated national climate plan (NDC) submitted in late October ahead of COP30.

The carbon border tax, which comes into force from January, was behind an attempt by the big exporters to scupper wider negotiations on climate action at the latest UN summit in Brazil.

Speaking in the aftermath at COP30, Wopke Hoekstra told the Financial Times that the petrostates had also been “more assertive” across the board in a bid to thwart climate agreements as the shift to cleaner energy systems accelerates.

“Some of those making money out of [fossil fuels] are seeking to prolong that process. We have seen this quite explicitly,” he said. “Some of the petrostates are seeking to at least slow down rather than speed up [the energy transition].”

He added: “I have sensed a certain sense of assertiveness that might not have been there five or 10 years ago.”

...

During public and closed-door meetings at the two-week talks, some of the developing countries argued the tax, or carbon border adjustment mechanism (CBAM), was a unilateral measure that would drive up costs, restrict trade and hinder their ability to grow their economies.

The tax will initially apply to products such as steel, cement and fertilisers, and aims to ensure imported goods meet similar green standards to those produced inside the EU or face an additional charge.

...

Hoekstra said the criticism was “clearly not very credible”, adding that in one-on-one conversations many countries “acknowledge it is clearly a climate tool” rather than a trade measure.

...

More than 80 countries had rallied around a proposal at COP30 for a so-called road map to help countries wean their economies off fossil fuels. But the plan failed to appear in the final agreement after objection from more than 30 other countries [particularly China, Russia, and petro-states in the Middle East].

The strange number lighting up Tawanda Majoni’s phone again and again felt like a warning.

Majoni, one of the Zimbabwe’s most respected journalists, soon learned where the calls were coming from: a federal police unit called Law and Order, notorious for abductions, torture and killings.

When unmarked cars rolled through his neighborhood after a relative was pressed for his location, Majoni packed a bag, tossed his cell phone’s SIM card so he couldn’t be tracked and fled the city, haunted by memories of slain colleagues. One was hurled from a moving vehicle in broad daylight. Another was beaten to death.

He knew he couldn’t run forever. After two weeks, he returned and answered one of the calls. An officer told him to come in: We have a case related to you.

...

A few days later, Majoni sat in a small, airless room at Law and Order offices, his lawyer ordered to wait outside. For three hours, officers grilled Majoni about his work, at one point sliding a printout across the desk—a tweet about a speech he’d given on World Press Freedom Day. They accused him of “inciting rebellion,” a treasonous offense.

The questioning made no sense until Majoni noticed a file on the desk: his photograph on top, and beneath it, text written in Mandarin Chinese.

He didn’t need to ask. His newsroom, the Information for Development Trust, had recently published exposes on Chinese mining projects that left open waste pits, poisoned rivers and displaced communities. “I know what this is about,” Majoni said.

The lead officer smiled, then pressed on about the tweet. Majoni walked free that day but stopped writing his weekly column. Later, he said, trusted police contacts confirmed what he already suspected: Chinese investors had been behind the interrogation.

...

The Chinese government’s repression of journalists at home is well known. Less visible is how that machinery now reaches far beyond its borders—and what that means for the environment.

...

An Inside Climate News investigation has identified more than a dozen journalists who have faced retaliation for reporting on environmental destruction and human rights abuses tied to China’s ventures in African countries, likely a stark undercount. Many of those cases involve projects under Beijing’s $1.3 trillion Belt and Road Initiative, a massive investment effort into mines, ports, railways, pipelines and other infrastructure in mostly poor countries.

...

When a project carries political weight for both the Chinese government and local authorities, that’s often when repression happens, according to Sarah Cook, author of the UnderReported China newsletter who has studied the country’s media influence operations for more than 15 years.

“If there are muckraking journalists or whistleblowers who might expose environmental issues, it could potentially be in the interest of both the local actors and the Chinese-linked ones to put a stop to that,” Cook said.

That suppression hides or sanitizes environmental and human rights abuses, even as Chinese President Xi Jinping promotes the Belt and Road Initiative as a model of “green” development and positions China as a global climate leader.

...

China’s media influence campaign targets a continent crucial to the planet’s climate and ecological balance. Africa is home to the world’s second-largest rainforest, vast carbon-rich peatlands and a quarter of all mammal species, including endangered mountain gorillas, pangolins and chimpanzees. Its degradation threatens not only 1.5 billion Africans, but also Earth itself.

Polluting companies from other nations have been linked to attacks on journalists, too. But China’s role is distinct.

“We’re talking about a nation that is not only highly repressive but also the second-largest economy globally,” said Cook, who worked for years for Freedom House, which defends civil liberties around the globe. “This creates an unprecedented situation.”

...

Censorship is only half the story. Journalists across the Global South are regularly flown to China on all-expense-paid trips that function like indoctrination, according to some participants. Chinese officials have also showered underfunded news organizations in other countries with investments and gifts—from computers to cell phones—and later exerted influence to spike stories and promote flattering coverage, journalists and government officials interviewed for this article said.

“The Chinese are very good with disseminating their agenda,” said Leo Mutisya, manager of press freedom and advocacy at the Media Council of Kenya, an independent government institution tasked with protecting media independence.

Mutisya pointed to the reach of Chinese state media in Kenya, their sprawling Nairobi offices and their cozy ties with the Kenya Broadcasting Corp., which gives a regular slot to one Chinese network and a radio frequency to another. (The Kenya Broadcasting Corp. did not respond to requests for comment.) Chinese officials also organize private lunches and parties with Kenyan journalists and editors, Mutisya added, and sponsor the country’s annual journalism awards—handing out Huawei smartphones to winners.

...

China has cast its overseas mining and other ventures not as a new form of imperialism but as “win-win” partnerships among nations of the Global South—countries, it says, long oppressed by Western exploitation. The message resonates in places like Zimbabwe, where resentment of Western interference runs deep and memories of colonial horrors remain vivid.

After winning independence from Britain in 1980, freedom fighter Robert Mugabe came to power in Zimbabwe as a symbol of unity and liberation. But by the late 1990s, his rule had hardened into autocracy—marked by election rigging, repression and state violence. Western nations responded with sweeping sanctions, in part over human rights abuses but also over Zimbabwe’s efforts to redress deep land inequities left by racist colonial rule.

...

Beijing’s lending to Zimbabwe has come free from Western pressure to improve democracy and human rights—a hallmark of what Beijing calls its “noninterference” policy.

But that principle, said Richardson, who is also co-executive director of Chinese Human Rights Defenders, is “nothing more than words on paper.”

“The Chinese government interferes left, right and center,” Richardson said, adding that Beijing spends “massive amounts of time and money and effort on putting forward and protecting a very particular image of what it is.”

Environmental reporters and researchers across Africa described how that influence plays out in the media.
