Environment

In this chapter, the principal environmental and health impacts of energy are discussed according to the scale at which they occur. About half of the world’s households use solid fuels (biomass and coal) for cooking and heating in simple devices that produce large amounts of air pollution—pollution that is probably responsible for 4–5 percent of the global burden of disease. The chief ecosystem impacts relate to charcoal production and fuelwood harvesting. At the workplace scale, solid-fuel fuel cycles create significant risks for workers and have the largest impacts on populations among

More than half of the global population now live in urban settings. Urbanization can and should be beneficial for health. In general, nations with high life expectancies and low infant mortality rates are those where city governments address the key social determinants of health.

This paper outlines briefly how the living environment can affect health. It explains the links between social and environmental determinants of health in urban settings. Interventions to improve health equity through the environment include actions and policies that deal with proximal risk factors in deprived urban areas, such as safe drinking water supply, reduced air pollution from household cooking and heating as well as from vehicles and industry, reduced traffic injury hazards and noise, improved working environment, and reduced heat stress because of global climate change.
