Four key techniques to encouraging pro-environmental behaviour

A new analysis of how to encourage pro-environmental behaviour highlights four effective techniques: goal-setting, prompts or reminders, witnessing the behaviour of others and introducing new behaviours that correspond with existing beliefs.

Commitment encourages green behaviour, but we need more insight into why

A new study indicates that ‘commitment’ interventions are effective in encouraging environmentally-friendly behaviour, both in the short- and long-term. However, to increase the effectiveness of such interventions, whereby people promise or pledge to perform certain behaviours, more research is needed on the psychological processes behind their effects.




av

Some green behaviour policies may have negative side-effects

A recent Swiss-US study of a short-term water saving campaign found that, although the programme successfully reduced water use, there was also an overall increase in electricity consumption by participants. The researchers suggest a ‘moral licensing’ effect may be in action, whereby people ‘trade’ a positive behaviour for a negative one.

A ‘nudge’ in the right direction: a tool for pro-environmental behaviour

An overview of research into ‘nudge’ theory and practices has recently been presented. While there is much evidence to show how humans make decisions, translating these psychological and economic insights into viable policy instruments that encourage behavioural change remains challenging, the authors conclude.




av

Green behaviour encouraged through strengthened environmental self-identity

Campaigns which remind individuals of the environmentally-friendly actions they already perform may motivate them to even more pro-environmental behaviours, new research suggests. If people identify themselves as environmentally-friendly, they are more likely to carry out green actions, even in the absence of any incentive.

Vegetables can absorb heavy metals from contaminated irrigation water

Certain vegetables take up heavy metals from contaminated water used for irrigation, a new study finds. The researchers grew vegetables in greenhouses similar to field conditions in Greece and found that concentrations of nickel and chromium increased in potatoes and onions, but not in carrots, when irrigated with water containing contaminant levels similar to those found in industrial wastewater.

High-yield crops have curbed agricultural land expansion, but care needed to avoid negative biodiversity effects

The widespread use of higher-yielding improved varieties of crops as part of the ‘Green Revolution’ has averted the conversion of between 18 to 27 million hectares of forests, woodlands and pastures in the period 1965 to 2004, according to a recent study. However, its authors caution that the relationship between these crops and land use change is complex, and good governance is needed to protect biodiversity from future expansion of agricultural land.

New approaches needed to evaluate active travel policies

A new analysis has indicated that policies to encourage active travel, such as walking and cycling, lead to a large but complex range of health benefits. However, it is not always possible to tell which policy has had which specific impact. The study argues for improved approaches to evaluating travel policy that consider indirect policy impacts.

How fast do species have to move to keep pace with climate change?

Species will have to shift their range much faster in some areas of the world than others to keep pace with climate change, according to new research. Those that live in certain areas, such as mangroves, tropical basins and deserts, may not be able to move fast enough over the next 100 years to survive.

Broader behavioural focus needed to mitigate climate change

Policy efforts have focused on modifying individual behaviour as one strategy to address climate change. However, this has been met with limited success and a new UK study suggests that policies to encourage behaviour change need to operate on multiple levels and that there is a need for greater co-ordination between individuals, governments, businesses and communities.

Greater emphasis of cost savings could reduce home energy use

New insights into energy saving behaviour in the home could help inform measures to ensure the EU meets energy efficiency targets. A new study shows that younger and more educated households have more positive attitudes towards energy conservation, and suggests that greater emphasis of the financial benefits associated with energy savings could help reduce energy use in households that are less-motivated to save energy for environmental reasons.

Personal experience with global warming drives mitigation behaviour

A number of studies have shown that the public misunderstand global warming. Taking a fresh approach, this study investigated the willingness of the public to take part in activities that mitigate climate change. An international survey of 24 countries revealed that this is strongly related to personal experiences with global warming. The authors say linking actions to benefits could encourage climate change mitigation behaviour.

Intensive grassland farming could have deep effects: sequestering significantly less soil carbon

Huge amounts of soil carbon have been discovered up to 1 metre below grassland in a recent UK study. Yet most carbon inventories do not assess soil deeper than 30cm. Furthermore, this research suggests that intensive management of grassland, involving high rates of fertiliser use and livestock grazing, may deplete carbon at these depths.

Processing London’s local food waste in an anaerobic digester avoids 3.9 tonnes of GHG emissions

Analysis of the operation of a novel, micro-scale anaerobic digester has shown that this technology could provide a useful means of processing food waste in urban areas. The study found that the digester, located in London and fed mainly with local food waste, avoided 3.9 tonnes of greenhouse gas emissions, while providing biogas for cooking, heat and power. Anaerobic digestion on this scale could play a part in reducing the amount of food waste that goes to landfill1 and contribute to the circular economy.
