Sustainable aviation fuels aren’t enough to drastically cut commercial aviation’s carbon footprint soon. Nor are redesigned planes or carbon-smart airports. Reducing demand for air travel may be the best answer.
The key to sustainable aviation fuels (SAFs) is cutting their carbon footprint during production, and making large amounts — no easy task.
More than 10% of carbon emissions will likely result from cutting trees, including natural forests, to make wood products over coming decades if action isn’t taken. Plantation forests if made more efficient could provide for a lot of timber needs, scientists find.
Sustainable liquid biofuels are needed to reduce the carbon footprint of fossil fuel-powered planes, ships, trucks and cars. Grass feedstock has shown promise in biofuel labs, but commercial scaling up may be an insurmountable hurdle.
The world’s largest producer of biomass for energy, Enviva, has seen its stock price tumble, as operational, financial and legal problems pile up, with investors possibly also concerned about the company’s tarnished green image.
With 2023 expected to see record amounts of brown macroalgae washing up on Caribbean beaches, green entrepreneurs in Mexico are turning waste into biogas, biofertilizer and even faux leather; all despite big bureaucratic hurdles.
Indonesia’s biofuel program was supposed to be a boon for small farmers. But although the country’s biodiesel production has skyrocketed, many farmers complain that the program hasn’t benefited them. Farmers…
Last year, a car fueled by human waste toured the European countryside, covering more than 2,000 kilometers (1,200 miles). It was the culmination of To-Syn-Fuel, a pathfinding project using technology…
Algae biofuels were initially hailed as a holy grail to sustainably power the transportation sector. Now after more than a decade of boom and bust, the industry says it’s on the verge of globally scalable, climate-friendly jet, ship and truck fuels.
At the start of the 2000s, the search for a “miracle” biofuel led to a stubby Latin American tree. But jatropha’s boom went bust when high yields and big eco benefits failed to materialize. Now some say it’s set for a return.
Revisions to the long-debated European Union Renewable Energy Directive (RED) have been approved. Those policies still support the burning of wood pellets to make energy, despite evidence of harm to forests and climate, say NGOs.
Biofuels have long been held up as a viable high-tech climate solution, but in practice they’ve often not lived up to their promise, causing environmental harm and in some cases being more carbon-intensive than fossil fuels.
Seemingly contrary to French President Macron’s green image, France is asking for an EU policy exemption to make biomass energy for Europe’s Spaceport in French Guiana — resulting in the clearing and burning of rainforest.
A biomass industry insider tells Mongabay in exclusive interviews that Enviva, the world’s largest maker of wood pellets for energy, is disingenuous in its green, eco-friendly claims to the public and stockholders.
While forest advocates had high hopes, the EU parliament voted this week not to declassify woody biomass as a renewable energy source, paving the way for more EU, U.S., and Canadian forests to be turned into wood pellets and burned.
Proponents of Swiss biomass are subject to an “Alice in Wonderland Syndrome,” expecting the public to believe in many impossible things, including that burning forest biomass is carbon neutral, sustainable and clean, critics say.
For the first time, a portion of the EU government has challenged the sustainability of burning forest biomass to make energy, a controversial policy pushed by the forestry industry but condemned by environmentalists.
The EU remains committed to burning forests to make energy, despite conclusive scientific evidence of its climate destabilizing impacts. In a new strategy, forest advocates plan to take the EU to court to fight that policy.
The E.U. continues to struggle with the irony of a commitment to conserving forests, while also burning forest biomass and ignoring the carbon emissions that causes — all in order to achieve a mandate to end burning oil, gas and coal.
The Glasgow climate summit is failing to address the danger of burning forests to make energy — a practice classified as carbon neutral, though science shows that its emissions exceed that of coal per unit of energy produced.
More than 100 scientists have issued a letter urging U.S. President Biden and Congress to remove provisions promoting logging, forest biomass and fossil fuels from the multitrillion-dollar infrastructure and reconciliation (Build Back Better) bills.
Cooking with firewood, diesel and gas all add to climate change and is harmful to health. So innovators have launched solar cookery enterprises that could transform Mexico’s fossil fuel-dependent businesses.
New research has tracked biomass industry carbon emissions, finding that U.S. wood pellet production, transatlantic shipping, and U.K. and E.U. pellet burning, plus a loss of stored forest carbon, combine in substantial unreported emissions.
Mongabay joins a noted forest ecologist in Olympic National Park to experience its magnificence and significance as a bastion of biodiversity and a carbon storehouse; protection of these vanishing U.S. and Canadian ecosystems is vital, say scientists.
The EU and the forestry industry say burning wood to make energy is carbon neutral and cleaner than coal. But critics say biomass is a disaster for forests, biodiversity and the climate. Mongabay reviews the evidence on both sides.
The waters of Lake Victoria — the world’s largest freshwater tropical lake — are clogged by water hyacinth that harm the fishery, economy and health. Locals are combatting the invader by turning it into biofuel.
The biomass industry says that burning wood to make energy is carbon neutral. Environmentalists say biomass is a disaster for forests, biodiversity and the climate. Mongabay reviews independent scientific evidence on both sides.
Though Shell, Chevron and others have abandoned the quest for the Holy Grail — a revolutionary algae biofuel that could be scaled up to replace oil — ExxonMobil continues the search; but is it all just greenwash?
Combining to hamstring Mexico’s climate-friendly biodiesel industry: a lack of regulatory support, a president favoring fossil fuels, competition from other industries for used cooking oil, and a crime network.
Biogas may play a key role in the global renewable energy transition, helping communities and nations meet multiple U.N. Sustainable Development Goals and their pledged Paris Agreement emissions cuts.
