Physical activity is good for health. Higher levels of physical activity are associated with reduced rates of breast and colon cancer, better mental health, lower obesity rates, lower heart disease, stroke (the list goes on).

Editor note: In this Blog, Caroline Shaw and Simon Hales reflect on the weak evidence on health co-benefits for some ‘big’ environmental policies, but also highlight that there are many ‘no-brainer’ actions that can be taken now with likely health and environmental co-benefit. They have recently published a systematic review “Health Co-Benefits of Climate Change Mitigation Policies in the Transport Sector”.
The transport sector globally generates about 23% of carbon emissions (about 16% of gross emissions in New Zealand). This is largely dominated by the use of light vehicles (see the pie chart below- note: energy use is a good proxy for carbon emissions in the transport sector). Transport emissions continue to grow rapidly, particularly in emerging economies, and by one account transport could represent half of all global emissions by 2050. Continue reading

We gave a presentation to Members of Parliament last week on taxes and subsidies on food, the pros and cons (slides here). In this blogpost we go into some extra detail on how such nutritional interventions compare to physical activity ones – in terms of health gain and potential for cost savings to the health system.

But living in shaky Wellington, makes one regularly wonder what might be the potential long-term benefits of earthquakes for public health. So here are a few examples relating to urban design and building design, disaster preparedness, and increased use of stairs over lifts. Continue reading
