As waste accumulation keeps expanding, it increasingly poses a serious threat to human health and the environment. Waste can be the source of many diseases, it emits large amounts of methane (a potent greenhouse gas), and exacerbates global warming. According to World Bank estimates, without urgent intervention, the current levels of global waste will increase by 70% by 2050. Graph 1. Global waste generation outlook by region 2016-2050 Proper management though can substantially mitigate the issues associated with waste. When discussing optim...

Historically, 9% of the plastic ever produced has been recycled and 12% incinerated, with the remaining 79% going to landfills. Plastic is now truly found worldwide, including within our very food and water, and it is already negatively impacting both wildlife...

According to the last four years’ data, Georgia has a chronic electricity deficit in ten months out of twelve, with the country showing an electricity surplus only in May and June (and, occasionally, in April and/or July). Despite the COVID-19 crisis dampening electricity demand in the country, 2020 was no exception. After two months - May and June - characterized by a positive generation-consumption gap, starting from July 2020 Georgia has been generating less electricity than required to cover consumption. To fill this deficit, Georgia imported energy ...

Covid-19 has exposed many countries to severe healthcare and economic crises, which have disproportionally adversely affected the most vulnerable and low-income parts of society. The current pandemic crisis, however, has also brought some interesting opportunities to light. For example, it has shown that relatively quick change is possible, as the unfolding of the COVID pandemic led to significant changes in working practices and individual behaviors, leading to dramatic reductions in greenhouse emissions around the world. Building on these experiences, ...
