A resource accounting tool for sustainable consumption

The report finds that the average Welsh resident's Ecological Footprint (EF) of 5.25 gha/cap is significantly higher than the global biocapacity of 1.8 gha/cap, implying that nearly three Earths would be needed if everyone lived like a Welsh resident. Food and drink consumption is the largest single component of the EF, while energy consumption is the primary driver of CO2 emissions. The study highlights a discrepancy between 'producer responsibility' (territorial emissions) and 'consumer responsibility' (emissions from consumption), noting that Wales carries an environmental burden for consumption occurring outside its borders. Sectoral analyses suggest that while organic farming and energy efficiency schemes offer some reductions, the most significant potential for lowering the EF lies in dietary changes, a shift toward renewable energy (particularly wind), and aggressive demand management in transport.

• The overall Ecological Footprint of Wales in 2001 was 15.2 million global hectares, with a per capita value of 5.25 gha/cap, which is slightly lower than the UK average of 5.35 gha/cap.
• Food and drink consumption is the largest component of the total Ecological Footprint in both Wales and the UK, contributing 1.29 and 1.34 gha per person respectively.
• There is a significant difference between territorial CO2 emissions and consumer-based emissions in Wales; territorial emissions are 14.5 t/cap, while consumer responsibility emissions are 11.3 t/cap, indicating Wales supports consumption outside its borders.
• The total material flow of consumption in Wales is estimated at 61 million tonnes, meaning the average resident consumes nearly 21 tonnes of materials and products annually.
• Dietary changes in primary school children could reduce their food-related Ecological Footprint by nearly 30%, from 1.24 gha to 0.89 gha, through the implementation of nutrition strategies.
• Increasing organic food production to 30% by 2020 (Ambitious Strategy) would only reduce the total food production footprint by 10%, from 6.6 million gha to 5.9 million gha, because organic farming requires similar or more land than conventional farming.
• Achieving the Welsh Assembly Government's target of 4 TWh of renewable energy by 2010 could reduce the energy sector's Ecological Footprint by 25%.
• Onshore and offshore wind energy are identified as the most efficient renewable options, with a significantly lower impact per GWh compared to municipal waste incineration.
• Personal transport accounts for 15% of the total Ecological Footprint for Wales, with private car use (0.49 gha/cap) and aviation (0.26 gha/cap) being the dominant drivers.
• The proposed 'Intra-Wales Scheduled Air Service' would increase the annual Ecological Footprint of domestic flights by 7% and generate between 690 and 1,279 tonnes of CO2 in the first year.
• The total Ecological Footprint of municipal waste in Wales is 0.71 gha per resident, with paper and card being the highest contributor due to both energy and real land requirements.
• Implementing the Home Energy Efficiency Scheme (HEES) across all houses in Wales lacking improvements could reduce domestic CO2 emissions by 17% and the Ecological Footprint by over 11%.
• Building homes to the BedZED standard could reduce the energy footprint by 84% and the material footprint by 24% compared to the average Welsh home.
• There is a strong correlation between income and environmental impact, with the highest Ecological Footprint (7.03 gha/cap) and lowest (4.10 gha/cap) among ACORN groups differing by 41%.
