There is a strong link between climate change and generation of waste. For example, methane gas, one of the greenhouse gases, produced at solid waste disposal sites contributes around 3-4 percent to the annual global anthropogenic greenhouse gas emissions. Global emissions from landfills are expected to increase from 340 Tg CO2 eq in 1990 to 1500 Tg CO2 eq by 2030 and 2900 Tg CO2 eq by 2050 in the Baseline scenario.
