1. Dealing with municipal solid waste by incineration accounts for less than 1% of UK emissions of dioxins, while domestic sources such as cooking and burning coal for heating account for 18% of emissions;

2. Less than 1% of UK emissions of oxides of nitrogen, which reduce air quality, come from municipal solid waste management, while 42% come from road traffic.

3. There are some areas where there has been less work and the science is less certain. These include emissions to soil and water (rather than air) and releases from forms of waste management other than landfill, such as composting, mechanical biological treatment or anaerobic digestion.
