As of 2017, 8.3 billion metric tons of plastic had been produced worldwide. Since about 40% is used in things that are thrown away relatively quickly (packaging and single use items), 6.4 billion metric tons had already become discarded materials needing to be managed. Only 9% of these discarded materials were recycled globally. The annual estimate of plastic entering our oceans globally is 5 to 13 million metric tons (MMT) per year. Latin America and the Caribbean (LAC) has an extensive populated coast, 119,000 km of coastline and over 205 million people living within 50 km of that coastline. Waste management infrastructure is still under development in many countries. Economic growth without fully developed infrastructure can lead to increased plastic leakage. This report focuses on municipal solid waste as a source of plastic input into the environment in LAC. The reports estimates that total plastic waste available to enter the ocean in LAC in 2020 was 3.7 MMT . Under business-as-usual projections, the report anticipates that the regional quantity available to enter the oceans in 2030 will be 4.1 MMT and 4.4 MMT in 2050.

AbstractThis paper empirically examines the electricity consumption - economic growth nexus in Uganda for the period 1982 to 2013, with a view to contributing to the body of literature on this topic and informing energy policy design in Uganda. Using capital stock as an intermittent variable in the causality framework, the paper employs Johansen-Juselius (1988, 1995) multivariate cointegration and VECM based Granger causality tests and finds a bidirectional causality between electricity consumption and economic growth in the long-term and distinct causal flow from economic growth to electricity consumption in the short-run, and short-term and long-term Granger causality from capital stock to economic growth, with short-run feedback in the opposite direction. Therefore, it implies that firstly, the Government of Uganda (GoU) can implement conservation policies only through reducing energy intensity and promoting efficient energy use to avoid decline in output and secondly, that the GoU should intensify its efforts towards capital accumulation in order to realize sustainable economic growth. Lastly, the empirical evidence that electricity consumption influences some short-term capital accumulation supports the GoU’s efforts to allow private sector investment in the electricity sector in an effort to increase electricity supply.
