New research in Australia has investigated the impact of labelling groceries with their level of CO2 emissions. A convenience store that introduced these labels found that the share of green (low CO2 emissions) purchases increased by 5 per cent. If these products were also low priced, the share of green purchases from the store increased by 20 per cent.

Gold mining areas in the Peruvian Amazon rainforest expanded from under 10 000 hectares in 1999 to over 50 000 hectares by 2012, and now destroys more forest than agriculture and logging combined, new research has shown. Using high-resolution satellite imaging, researchers estimated gold mining areas to be twice as large as estimated by previous studies, which did not include the combined effects of thousands of small, mainly illicit, mining operations.

Record high prices for gold have driven a recent six-fold increase in deforestation in parts of the Peruvian Amazon with damage that can be measured from space, according to a new study. Rates of forest clearance and imports of mercury, used to process gold ore by local, small-scale miners, were both found to increase with the rising international price of gold.

Effective greenhouse gas (GHG) mitigation measures to stabilise global temperature change to no more than 2°C above pre-industrial temperatures would also substantially reduce air pollutant emissions, recent research predicts. A variety of mitigation options are available, including switching from fossil fuels to renewable sources of energy. To achieve the necessary GHG emission reductions, one key option is to impose carbon taxes. However, these would need to be high to help achieve this target, according to the study’s authors.
