The iConnect (Impact of COnstructing Non-motorised Networks and Evaluating Changes in Travel) study aims to measure and evaluate the changes in travel, physical activity and carbon emissions related to Sustrans' Connect2 programme, which is an ambitious UK-wide project that will transform local travel in 79 communities by creating new crossings and bridges to overcome barriers such as busy roads, rivers and railways, giving people easier and healthier access to their schools, shops, parks and countryside.

"The increasing global prevalence of overweight and obesity has serious implications for the environment, as well as for health. We estimate the impact on greenhouse gas emissions of increases in the population distribution of body mass index (BMI). Compared with a normal population distribution of BMI, a population with 40% obese requires 19% more food energy for its total energy expenditure. Greenhouse gas emissions from food production and car travel due to increases in adiposity in a population of 1 billion are estimated to be between 0.4 Giga tonnes (GT) and 1.0 GT of carbon dioxide equivalents per year."

The Healthy Weight for Children Hub is an interactive information network designed to improve access to the latest available evidence and best practice in the South West.
