The increased use of hydrofluorocarbons (HFCs) in the production of refrigerators, air conditioners, and other products could play a significant role in accelerating global warming, a new UN report warns.
Without stricter regulations, the United Nations Environment Program (UNEP) report says, the (more…)

Peat, the accumulated turf made up of decayed vegetation, forms in many parts of the world in places like bogs, moors, and swamp forests. Due to its high carbon content, it can be harvested and burned as fuel. There are estimates that the global inventory of peat, covering 2 percent of all land area, contains 8 (more…)

A regional cap-and-trade program launched in the northeastern U.S. three years ago has saved customers nearly $1.1 billion on electricity bills, helped create 16,000 jobs, and has retained more than $765 million in local economies by reducing the demand for fossil fuels, according to a new analysis. (more…)

In many parts of the world, including areas of India, central Asia and the Sahara desert where the climate is arid and the landscape barren, these standing crops can soak up carbon dioxide from the atmosphere and convert it into oxygen. The new research is soon to be published in the European Journal of Plant Science and Biotechnology. (more…)

Carbon sequestration is the capture of carbon dioxide (CO2). This is the process of carbon capture and storage, where carbon dioxide is removed from flue gases, such as on power stations, before being stored in underground reservoirs. There are also natural sequestration processes such as the ocean. (more…)

Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change. The study by Tom Wigley, who is a senior research associate at the National Center (more…)

Measuring the emission of greenhouse gases from croplands should take into account the crops themselves. That’s the conclusion of a study in the Sept.-Oct. issue of the Journal of Environmental Quality, which examined the impact of farm practices such as tillage on the greenhouse gas, nitrous oxide. Expressing (more…)

The U.S. Department of Energy has selected four projects for continued research into developing carbon capture technologies, with the goal of achieving 90 percent carbon dioxide removal.
While existing carbon capture technologies require enormous amounts of energy — adding as much as (more…)

Breeding crops with deeper roots could significantly reduce atmospheric levels of carbon dioxide and make crops more drought resistant, according to a study by a researcher at the University of Manchester.
Reporting in the journal, Annals of Botany, professor (more…)

By now, we’re all familiar with the idea that our lives, from the food we eat to the cars we drive, have carbon footprints. Flying comes under special scrutiny both because jets pump carbon directly into the upper atmosphere and because it is often volitional — we fly for business instead of teleconferencing and jet to (more…)
