Public health benefits of strategies to reduce greenhouse-gas emissions: urban land transport.

We used Comparative Risk Assessment methods to estimate the health effects of alternative urban land transport scenarios for two settings-London, UK, and Delhi, India. For each setting, we compared a business-as-usual 2030 projection (without policies for reduction of greenhouse gases) with alternative scenarios-lower-carbon-emission motor vehicles, increased active travel, and a combination of the two. We developed separate models that linked transport scenarios with physical activity, air pollution, and risk of road traffic injury.

Energy and transport.

We examine the links between fossil-fuel-based transportation, greenhouse-gas emissions, and health. Transport-related carbon emissions are rising and there is increasing consensus that the growth in motorised land vehicles and aviation is incompatible with averting serious climate change. The energy intensity of land transport correlates with its adverse health effects.

Let's ask them: a national survey of definitions of quality of life and its enhancement among people aged 65 and over.

This study aimed to explore older peoples' definitions of, and priorities for, a good quality of life for themselves and their peers. Nine hundred and ninety-nine people aged 65 and over, living at home in Britain, were interviewed for the study. Good social relationships were the most commonly mentioned constituent that gave respondents' lives quality (mentioned by 81 percent).
