Climate change: Are forests carbon sinks or carbon sources?

The world is getting a better understanding of just how important forests are in the global fight against climate change.

New research, published in Nature Climate Change and available on Global Forest Watch, found that the world’s forests sequestered about twice as much carbon dioxide as they emitted between 2001 and 2019. In other words, forests provide a “carbon sink” that absorbs a net 7.6 billion metric tonnes of CO2 per year, 1.5 times more carbon than the United States emits annually.

These animals can eat plastic waste

Scientists looking to find ways to tackle the world’s mounting plastic waste problem are hoping a caterpillar with an unusual diet can help.

More than 50 species of plastivore – small organisms that consume plastic – have been discovered, which are mostly bacteria and fungi but include some insects capable of turning plastic waste into energy.

We can stop plastic pollution at the design stage - here's how

Marine plastic pollution, commonly referred to as marine plastic litter, is a major global environmental problem. It harms marine species through ingestion and entanglement, violates the integrity of ecosystems, inhibits growth of marine plants, accumulates and transports pathogens that may cause disease and injuries to marine animals, plants and humans, and partly ends up in the food chain. Moreover, it causes economic losses due to reduced fishery yields, declining amenities for tourism, and damage to shipping and related infrastructure.

5 ways to reduce your household waste

  • The UK is the largest plastic waste producer in Europe.
  • Two-thirds of this waste is exported to poorer countries, where facilities to process it might be inadequate.
  • Consumer change is part of reducing the volume of waste we produce.
  • From using less, to buying local here are 5 tips to help you reduce your waste.

    The UK is the largest plastic waste producer in Europe and one of the biggest producers of plastic waste in the world, second only to the US. The UK produces 99kg of plastic waste per person per year. And it exports about two-thirds of this waste to poorer countries such as Malaysia, Pakistan and Vietnam.

National laboratories point to sugars as key factor in ideal feedstock

Popular wisdom holds tall, fast-growing trees are best for biomass, but new research by two U.S. Department of Energy national laboratories reveals that is only part of the equation.

Of equal economic importance, according to scientists from the National Renewable Energy Laboratory and Oak Ridge National Laboratory, is the amount of sugars contained within the cellulosic biomass that can be converted into fuels.
