These high school runners train in 'nasty air,' so they're working to clean it up

The rapid development of emerging economies across Asia and Africa is lifting hundreds of millions of people out of poverty - but there is much debate as to how to best structure this growth. If these economies evolve in the same way as in the West - with unchecked, excessive resource consumption and heavy pollution - the planet may be on the fast track to disaster. Earthrise explores how these nations can grow sustainably using improved, eco-conscious technologies like renewable energy and eco-friendly farming practices.

Kathmandu is one of the most polluted countries in the world--a title once caused by the excess smoke produced by brick creation in the city. However, after a 2015 earthquake destroyed much of the old technology used to fuel the brick industry, leaders took to leveraging updated technology with an increase in energy and production efficiency.

In California’s wildfire-prone Sierras, forest managers are turning to an ancient, if not quite intuitive, tool: more fire. In 2019, the Forest Service will manage 250,000 acres with controlled burns and “mechanical thinning,” using equipment to take out small trees. Though such plans face some hurdles, states across the country are adopting them, reducing wildfire severity while often benefiting ecosystems.

A handful of sustainability-oriented startups are working with concrete companies around the world to reduce their carbon footprint. The concrete & cement industry is responsible for 8% of global carbon emissions; however, with technologies that capture CO2 within solid concrete, some companies have been able to decrease their emissions, while improving efficiency in the process.

Official in Bangkok, Thailand unleashed a small fleet of drones to deal with the hazardous levels of air pollution plaguing the city. The drones were outfitted with canisters capable of spraying water and a "non-hazardous chemical spray." The pilot project successfully reduced air pollution by small amounts.

Norway has been able to have a productive relationship with oil companies, while, at the same time, retain control over resource development and grow its resource revenue. Through the country’s culture of local control and indigenous governance, its resource revenue is over $1 trillion and helps pay for some of the country’s social programs; a model that could be potentially work in other places around the world.

After being known as a polluted mining town, politicians, scientists, industry officials, and residents of Sudbury, Ontario, were able to come together to restore its land. After 40 years and $33.5 million, they are about halfway through recovering about 200,000 acres of land. So far, they’ve been successful at restoring air quality, neutralizing soil to allow for replanting, and restocking lakes with fish. While some locals think the mining companies should have done more, the collaborative spirit could be a model for other communities looking to improve the environment.

As a way to reduce the amount of diesel fuel that powers trains, governments and transit companies around the world are turning to solar panels as a way to utilize renewable energy. In Australia, a solar train launched in 2017 that uses lithium-ion batteries that are charged by solar panels on the roof of the carriages. And a rail line in the United Kingdom uses energy from a solar farm to keep the train running. Scaling solar panels for nation-wide transit systems can be challenging, but many countries are committed to eliminating the use of fossil fuels on their rail networks.

Old and neglected housing contributes to climate change because it runs on fossil fuels. In New York, outdated heating systems waste two-thirds of energy. The New York City Housing Authority is not only trying to create better, safer, livable affordable housing, but also cleaner and more sustainable housing. While the city is just beginning to explore how to do that, other cities, like Paris, have already begun the work of updating old buildings that are used for affordable housing and can offer a model for American cities.

London charges higher-emission vehicles every day they enter the city center, called the Ultra Low Emission Zone, on top of the already existing London Congestion Charge for non-electric vehicles to enter the zone. Since the charges were implemented, the city has seen an increase in electric vehicle adoption and improved air quality.
