This study employs a Pooled Mean Group estimator to examine the nexus between economic growth and fossil and non-fossil fuel consumption for 53 countries between 1990 and 2012. The global sample was divided into four categories: developed exporters, developed importers, developing exporters and developing importers. The purpose of these categories was to observe whether factors unique to these countries influence the relationship between energy consumption and economic growth. With the exception of developing importers, evidence of bi-directional causality between fossil fuel consumption and real GDP across all subsamples is observed. This leads to the conclusion that efforts to directly conserve fossil fuels may harm economic growth. In terms of non-fossil fuel use, the results are more diverse. Bi-directional causality between non-fossil fuel use and real GDP is found in the long and short run for developed importers; bi-directional causality only in the long run for developed exporters; negative long-run causality from real GDP to non-fossil fuels for developing exporters; and long-run causality from non-fossil fuel use to real GDP for developing importers. These results lead to the conclusion that other factors have been responsible for the progress seen in non-fossil fuel use. Thus it is concluded that economic growth on its own is insufficient to promote clean energy development. There is a need for policy makers to create an environment conducive to renewable energy investment.

Questions and potential misperceptions have arisen about the potential contribution of liquid detergent capsules to the environmental microplastics issue. The film of these detergents is highly water soluble, also in cold water, as it must fully dissolve during every type of washing process. Water-soluble grades of polyvinyl alcohol, the most commonly used detergent capsule film material, are recognised to be biodegradable. In the current paper, adequate biodegradability is confirmed by means of ready biodegradation screening tests, across a range of polyvinyl alcohol detergent grade films. The high water solubility in itself implies that detergent capsule films are not within the microplastic scope. Furthermore, their biodegradability ensures there is no concern for persistence or accumulation in the environment.

This study assessed the effectiveness of safety communication on the back labels of hazardous products (with regulatory and safety information as dictated by regulatory requirements), with household detergents as a test case. The potential of simplification to increase label effectiveness was evaluated by comparing the currently used labelling approach with two simplified alternatives. The labels mainly differed in terms of the amount of information and the prominence of pictograms. The generalisability of theoretical insights on the effectiveness of pictograms in safety messages to a more real-life context was tested by (a) realistic labels containing several other information elements besides the safety information and (b) target users who are knowledgeable about the product type. One thousand eight hundred (1,800) respondents participated in an online experiment and were randomly exposed to one of the labels. The positive cognitive and behavioural effects commonly attributed to pictorials could not be confirmed, but positive affective effects did emerge. Specifically, even though participants were asked to carefully read the label, they did not spend enough time to process all the content except for the most simplified label. The results did not show meaningful differences between the three labels in terms of information recall (which was poor for all executions), hazard perceptions and behavioural intentions when confronted with an accident. In contrast to this lack of differentiation in cognitive and behavioural intention effects, we did find a clear difference in the affective measure. A majority of the respondents preferred the simplified safety labels. As such, avoiding information overload, and conveying the information in an easier way by means of more prominent use of pictograms, appeared to be appreciated by consumers of household products, while it did not negatively impact label effectiveness.
