The greenest people in the world...

Research from energy comparison experts MoneySuperMarket details how countries around the world are tackling climate issues through their sources of energy, their local waste, and how much deforestation occurs - as well as air pollution, energy consumption, and numerous other factors.

Green Africa
Mozambique residents cause the least impact on the world’s climate, using almost 100% green and sustainable energy, creating almost no waste, and producing almost no carbon dioxide. They do, however, fail to treat any local wastewater, which may have adverse effects on the local environment as well as their own health.

Other top countries included:

1. Ethiopia - While Ethiopia’s energy consumption is markedly lower than Mozambique’s - 1.75 Btu/capita/year compared with 8.9 for Mozambique - their waste production and exposure to pollutant PM2.5 particles are both higher.
2. Zambia - Unlike the top two countries, Zambia treats a portion of their wastewater - 4.2% of it. However, pollutant particles and energy consumption are significantly higher, making this only the third greenest population.
3. Latvia - Latvia has the highest proportion of wastewater treated in the top five, with only 5.8% going untreated. Energy consumption is, however, vastly higher, at 74 Btu/capita/year, and green energy is much lower at only 68% of all energy used.
4. Kenya - Kenya ranks among the greenest countries in the world - but compared with the rest of the top five, green energy usage is comparatively low and pollutant particles are high - as are CO₂ production and waste produced.

British energy
Britons use 57% less energy than Americans - and British energy is 77% greener. The green initiative also beats that of France and Germany - but despite the European comparisons, Britain only managed to rank 53^rd out of 102 overall. This comes as a result of high treatment of polluting wastewater, but a comparatively low 22% of UK energy being green.

The French approach to energy is slightly worse, with green power at a low-ranking 17% of their total usage, and they generate seven percent more daily waste per person than the British public.

High human impact
Trinidad and Tobago, on the other hand, uses more energy per person than anywhere else - only 0.23% of which is green. The Caribbean country also produces a remarkably high 37.1 tonnes of CO₂ per person each year - 118% more than the United States.

Sustainable practices
There’s still much that can be learnt from the countries towards the top of the rankings - many, like Mozambique, Ethiopia and Zambia, use nearly 100% green energy, relying in particular on hydropower to provide energy for their citizens.

Adopting green energy on an individual level can be difficult or expensive. But a more practical approach for someone looking to reduce their effects on the climate can turn their attention instead to their waste production, and what they do with that waste. Many of the highest-ranked countries produce minimal waste, while others have a strong approach to recycling.
