Fomenting biogas production among agricultural producers may seem at first glance to be a distraction from the purpose of Itaipu, the giant hydroelectric power plant shared by Brazil and Paraguay, but in fact it is part of their energy business strategy.
Vast amounts of valuable energy, agricultural nutrients, and water could be recovered from the world’s fast-growing volume of municipal wastewater.
The increased frequency of climate-induced weather extremes and public opinion pressure are forcing even major fossil fuel exporting countries in West Asia to make a big push towards renewable energy.
One of the main discussions at the COP25 climate change talks was Article 6
, which is designed to provide financial support to emerging economies and developing countries to help them reduce emissions by using global carbon markets. Carbon pricing is an essential piece of the puzzle to curb emissions. Without a value on carbon, there is less incentive to make positive changes, especially in the private sector. The most efficient way to carry this forward is to allow trading of carbon both nationally and internationally, which will ensure the lowest cost of mitigation for participants globally.
The intense white brightness of the salt flats interrupts the arid monotony of the Puna in northwest Argentina, resembling postcards from the moon. Beneath its surface are concealed the world's largest reserves of lithium, the key mineral in the transition to clean energy, the mining of which has triggered controversy.
"They're the ideal duo," because the combination of solar and biogas sources makes it possible to provide electricity around the clock, one during the day and the other at night, says Anelio Thomazzoni, a pig farmer who has become a producer of clean energy in southwestern Brazil.
At a time when the world is battling unprecedented drought, bushfires, rising sea levels and water shortages, reducing energy use across industry is one powerful way to fight climate change in the immediate term.
Mass public pressure backed by the weight of scientific reports is starting to bring governments to their senses as the annual UN climate summit kicks off in Madrid today.
During the 25th round of climate change negotiations starting today in Madrid, Spain, African civil society organisations will call on governments from both developing and developed nations to play their promised roles in combating climate change.
We are facing tense and turbulent times around the globe. Rising inequality is a danger everywhere. Trade and technology tensions are building. Growth forecasts are being revised down. Unease and uncertainty are going up. This is a global phenomenon. No region is immune.
The UN Climate Action Summit
2019, which took place in the days leading up to the 74th UN General Assembly, delivered new pathways and practical actions for governments and private sector to intensify climate action.
The sun's rays are also used to cook food and thus replace the burning of firewood and gas, improve the health of local residents and fuel the energy transition towards the use of renewable sources - the objectives of an enterprise in the southern Mexican state of Oaxaca.
"On moonless nights it was very difficult to walk around this town," says Celia Vilte, a teacher from San Francisco, a highlands village of just 54 people in the extreme northwest of Argentina whose centre is not a town square but 40 solar panels, which provide one hundred percent of its electricity.
Good news: the graph depicting climate investments has been steadily increasing. Climbing from the 2012 figure of $360 billion in climate investments across the world to close to $600 billion currently.
In the 2014 China-US joint announcement on climate change, China promised to peak its greenhouse gas (GHG) emissions around 2030. Later this commitment was cemented in the Paris Agreement signed in 2016.
"Biogas is the best energy, it has no contraindications," and if you combine it with solar it becomes "the best energy business," at least in Brazil, says Anélio Thomazzoni.
Last week, world leaders gathered at the United Nations in New York for the Climate Action Summit. Their goal was simple: to increase ambition and accelerate action in the face of a mounting climate emergency.
A week ago, downtown New York witnessed one of the most historic moments in the climate action moment — hundreds of thousands of people attended the Climate Strike, where teen activists delivered powerful speeches and blows to world leaders for not taking climate change seriously.
The state of Santa Catarina in southern Brazil is the largest national producer and exporter of pork and this year it also leads in exports of chicken, of which it is the second-biggest producer in the country.
Biogas has the potential to provide 36 percent of the electricity consumed in Brazil or replace 70 percent of diesel if purified as biomethane, according to the Brazilian Association of Biogas and Biomethane (Abiogas).
Arama Sire Camara, a fruit and vegetable seller in the province of Kindia, some 135 km from the Guinean capital of Conakry, feels safer trading well into the night thanks to the Rural Electrification Project, financed by 21-million-dollar investment by the African Development Bank.
“With lighting on the road at night and illuminating our goods, it means we are safer, especially with all the cars on the road. You can work for longer after nightfall, and so we can make more of our products,” she says.
