Papua New Guinea Reinstates Forest Carbon Credit Trading

Papua New Guinea plans to "swiftly" remove the prohibition on forest carbon credit initiatives, according to statements made by the country’s climate minister to AFP on Thursday. This move will allow access to its extensive wild areas as a means of compensating for worldwide emission levels.

The island of New Guinea is covered by one of the largest expanses of tropical rainforests globally, assisting Earth’s respiratory function by absorbing carbon dioxide and converting it into oxygen.

In recent years, international businesses have acquired extensive areas of woodland with the aim of selling carbon offsets, committing to preserve trees that might otherwise be lost to deforestation or clearance for development.

However, a series of mismanagement scandals compelled Papua New Guinea to briefly suspend their "voluntary" carbon market in March 2022.

The Environment Minister, Simo Kilepa, informed AFP that due to the implementation of new safety measures, the three-year moratorium will be "lifted right away."

Kilepa mentioned that Papua New Guinea is lifting the ban on voluntary carbon markets.

We currently have established carbon market regulations along with guidelines for managing and overseeing the carbon market.

Officials from Papua New Guinea’s national climate agency stated in a recent briefing that their country aims to emerge as a significant participant in global carbon trading.

Carbon credit programs are considered essential for preventing the devastation of Papua New Guinea’s lush rainforests, believed to harbor approximately seven percent of the world's overall biodiversity.

Prior to the 2022 moratorium, foreign-backed groups could enter into carbon credit agreements directly with village leaders.

Ultimately, they compensated landowners to ensure that portions of the rainforest were not cleared for agriculture, converted for mining purposes, or cut down to produce timber.

By safeguarding forests that were destined for destruction, these businesses created carbon credits which they could then trade on global marketplaces.

'Carbon cowboys'

Some ideas were incredibly ambitious — for instance, a carbon trading initiative set along Papua New Guinea’s north shore could have become one of the largest globally, as reported by Carbon Market Watch.

But Papua New Guinea's carbon market was mired in controversy, with one regional governor alleging some foreign firms were little more than "carbon cowboys" out to make quick cash.

A probe conducted by Australia’s national public broadcaster ABC claimed that logging activities were continuing within rainforest areas designated for carbon credit programs.

Some landowners grumbled that the generous commitments made by their foreign associates were mostly not kept.

"Sustineo, an Australian environmental consultancy firm, reported that efforts to initiate projects led to land conflicts and gave rise to 'Carbon Cowboys,'" they stated.

Various carbon credit programs globally have faced a series of comparable criticisms.

There is no standardized set of regulations for these transactions, and numerous projects have faced accusations of dealing in nearly valueless credits.

Governments frequently require significant polluters to compensate for their emissions by participating in compulsory carbon credit programs.

However, companies, nonprofits, and people have the option to purchase credits from what are known as voluntary carbon markets.

The voluntary program in Papua New Guinea is part of an international framework called REDD, which stands forReducing Emissions from Deforestation and Forest Degradation in developing nations.

Papua New Guinea has been working on a bilateral agreement that might result in it generating carbon credits for the city-state of Singapore.

In 2023, Papua New Guinea entered into an agreement with Blue Carbon, a company based in Dubai, known for acquiring large tracts of land throughout Africa primarily for carbon credit purposes.

EVs on Track to Cut Europe's CO2 Emissions by 20 Million Tonnes This Year, But Transport Still the Biggest Polluter

According to an analysis conducted by the advocacy organization Transport & Environment (T&E), a rise in the adoption of electric vehicles will result in Europe saving approximately 20 million tonnes of CO2 this year.

This is comparable to the pollution produced by eight coal-fired power stations and signifies one encouraging development in an industry famously challenging to electrify.

Transportation is the sole sector that has not reduced its emissions since 1990; it trails other sectors such as industry, power production, and construction, accounting for approximately a third Regarding EU pollution. However, T&E’s most recent State of European Transport report reveals new insights. report shows that emissions have started to decrease.

"The European Union's environmental policies are finally having an impact. With the shift towards electric vehicles, we're witnessing a significant reduction in transportation-related emissions," states William Todds, who serves as the executive director of T&E.

In 2024, Europe's transportation industry emitted 1.05 billion tonnes of CO2, which marks a decrease from the 1.1 billion tonnes recorded in 2019—a reduction of 5%. This decline can primarily be attributed to the significant increase in electric vehicle usage, effectively displacing gasoline and diesel-powered vehicles over recent years.

Now is certainly not the moment to retract environmental initiatives," asserts Todts. "To ensure the continent’s prosperity and security, this is the time to intensify our efforts.

Effective environmental measures have led to a significant increase in electric vehicle adoption.

Automobiles are the largest contributors to transportation-related pollution, emitting a combined total of 450 megatonnes of CO₂ equivalent emissions annually, accounting for 13 percent of all greenhouse gas emissions within the European Union.

Battery electric vehicles (BEVs) are already three times more environmentally friendly than petrol vehicles, and this advantage will increase as the electricity used to power them becomes even greener, according to T&E.

The advocacy organization forecasts that there will be 8.8 million battery electric vehicles on European roadways this year, indicating that one out of every five newly purchased cars in the EU will emit no exhaust fumes.

The report attributes much of this advancement primarily to the European Union's CO₂ regulations for vehicles. These guidelines offer clarity for automotive manufacturers as they approach the 2025 objective. Companies have consequently invested resources into altering their manufacturing processes toward electric vehicle production, coinciding with decreasing battery costs. This convergence suggests that by 2025, we can expect a wider array of cost-effective and mainstream electric model options.

Is the EU equipped with sufficient charging stations for all its electric vehicles?

Many people view insufficient charging stations as a barrier to purchasing an electric vehicle. However, T&E analysis indicates that the infrastructure has kept up with the increase in battery-electric vehicles.

Under the EU Alternative Fuels Infrastructure Regulation (AFIR), each country has annual targets based on a ratio of total charging power output and the number of electric cars on the road. The bloc’s 2025 target was exceeded back in 2022, and there are now more than 1,100 charge points .

Across major roads, 11 nations have achieved the EU objective of installing charging stations every 60 kilometers. The AFIR is further encouraging the deployment of electric vehicle charging facilities in urban areas, with cities like Oslo, Amsterdam, Copenhagen, Brussels, and Ljubljana at the forefront of this initiative.

Vehicle manufacturing emissions 'the next frontier' according to T&E

Electric vehicles aren't the ultimate solution to Europe's widespread issues. transport problem , however.

Firstly, their manufacturing process remains quite environmentally damaging. Given that approximately 10 million new cars are sold annually, the production of these electric vehicles (not including batteries) contributes to roughly 50 megatons of CO2 emissions.

According to T&E, batteries, aluminum, and steel are the primary sources of emissions that should be addressed. The organization is advocating for increased usage of eco-friendly and recycled steel.

Aircraft emissions are hindering attempts to make transportation more sustainable.

Even with advancements on European roadways, the researchers caution that rising air pollution is offsetting attempts to reduce transportation-related emissions.

Europe’s airlines emitted 143 million tons of CO₂ last year, an increase of almost 10 percent from 2023.

The report reveals that emissions from Europe’s maritime activities stay notably high at 195 Mt CO2e, with both industries being significantly dependent on fossil fuels.

However, with shipping now incorporated into the EU’s carbon trading system ( ETS Combined, both sectors are expected to generate €5 billion in revenue in 2024, as estimated by T&E.

These resources can help close the cost difference between eco-friendly e-fuels and conventional fossil fuels, which is crucial for advancing efforts in combating climate change and ensuring stable energy supplies.

"Europe is gradually freeing itself from its reliance on oil, yet we continue to spend hundreds of billions on imports from foreign nations," states Todts.

In 2023, fossil fuel imports continue to be the primary energy supply for transportation, accounting for 96 percent of Europe's crude oil and 90 percent of its natural gas sourced internationally. These fuels frequently originate from authoritarian governments and come at considerable cost.

Alien Hunt Gets Easier: New Oxygen Reaction Discovery Could Be Key

'Just as oxygen is essential for the lungs, hope is vital to giving purpose to one’s life.'

This quote comes from the book "Eternal Hope" written by Emil Brunner, who was a Swiss theologian.

The man actually intended to convey that oxygen is the key to discovering life outside of our planet.

Oxygen is considered essential for life on Earth because it is primarily generated by living organisms.

However, researchers have found a novel method for oxygen to develop in planetary atmospheres dense with carbon dioxide, eliminating the requirement for living organisms.

Researchers told Space.com How they searched for innovative methods to generate molecular oxygen by colliding CO2 with helium.

This method of producing oxygen is termed an 'abiotic' process, which means it does not entail living organisms.

The enrichment of Earth’s atmosphere with oxygen, occurring approximately between 2.1 to 2.4 billion years ago, remains one of the greatest enigmas in history. Prior to this event, which geologists refer to as the Great Oxidation Event, much of our planet was enveloped in the pungent greenhouse gas CO2.

The presence of oxygen became noticeable in the atmosphere once ancient marine microorganisms developed the capability for photosynthesis. Following their exposure to sunlight, these organisms released oxygen into the environment.

Much of this oxygen did not persist for an extended period. Given the numerous volcanoes active back then, hydrogen likely consumed most of it.

However, after several hundreds of millions of years, as the Earth started to cool down, it provided an opportunity for our unusually oxygen-abundant atmosphere to develop.

Shan Xi Tian and Jie Hu from the University of Science and Technology of China chose to investigate how helium produced through interactions between solar winds and a planet's atmosphere might generate oxygen.

In this process, helium forms ions—charged particles that behave akin to wrecking balls, colliding with CO2 and causing it to smash into other molecules.

'This phenomenon can be observed in Mars' upper atmosphere as it contains numerous He+ ions (from solar winds) along with CO2,' explained Hu.

However, despite the formation of O+, O2+, and CO2+, O2 does not appear, at least not on Mars.

Tian and Hu employed three methods from their toolkit to put their concept to the test.

The initial method is time-of-flight (TOF) mass spectrometry, where particles become ions and are accelerated to achieve equal kinetic energy. The duration taken for them to cover the same distance is utilized to determine their mass.

The duo utilized a 'crossed-beam apparatus' for colliding two molecules, along with 'ion velocity maps' to document the paths and speeds of the resulting ions.

'We discovered a significantly different mechanism for producing O2 from molecular CO2,' Tian stated. 'Specifically, via the interaction between helium ions [He+] and CO2.'

To put it simply, Tian and Hu’s research discovered that life-supporting oxygen might develop on planets with CO2-heavy atmospheres before any living organisms have appeared there.

David Benoit, who serves as a senior lecturer in Molecular Physics and Astrochemistry at the University of Hull’s EA Milne Centre for Astrophysics, now indicates that the quest is underway to locate planets where this might plausibly occur.

'This innovative mechanism is expected to be included in upcoming models designed to forecast the atmospheres of other planets,' Benoit stated to Space.com. 'It will assist us in more accurately explaining the levels of oxygen we may discover.'
