The Right Green


Deforestation is the second-leading cause of climate change. But just randomly planting new trees can sometimes do more harm than good by reducing biodiversity. Therefore, Aadya Joshi founded The Right Green and developed a database including over 15000 plant-insect feeding relationships from different eco-regions of India. Using her newly invented BioPower Index, landscapers, gardeners and civic authorities can plant the best biodiversity supporting plants. Her educational and outreach workshops have empowered and enabled communities to restore healthy ecosystems, rich in biodiversity, while also addressing climate change.


The jury's announcement:

Through her great understanding of the dangers of biodiversity loss and deep knowledge of the roles of plants and trees' ability to prevent it, Aadya has through her initiative ‘The Right Green’ combined modern database technology with the traditional knowledge of native plants to empower local communities to take action. The fact that Aadya attaches particular importance to the dissemination of knowledge about plants is impressive and was an important factor in the jury's decision. With the right support, the initiative has great potential to be scaled-up in India and even globally, and it serves as an excellent example how the combination of traditional knowledge and modern technology through bottom-up action can contribute to address major environmental challenges.

José Adolfo

Project: Eco Bank

Started an "eco-bank" that transforms environmental awareness and the act of recycling into a currency that children can use to buy products at the eco-bank or exchange for real money.

The jury's announcement:

José's eco-bank is a brilliant way of linking economy and climate impact, both in thought and practice. Children can take micro loans, and pay, with items that are recyclable. The system clearly illustrates that the planet's common resources are limited and that we must be climate conscious and recycle the products that we no longer use. It creates awareness of consumption. This way caring about the environment becomes an investment. A system that gives children both economic independence and power to influence the climate.

The potential impact is amazing.

Nav & Vihaan Agarwal 2019

Project: One Step Greener


Nav and Vihaan Agarwal, two brothers of 12 and 15 years old, created the organization One Step Greener, which strives for a zero-waste future, aiming to reduce air pollution and improve health and wellbeing of people in New Delhi.

The jury's announcement:

Air pollution is today the single biggest environmental threat to human health according to the WHO with 9 out of 10 people breathing toxic air. New Delhi in India is the capital with the world's dirtiest air. Here, as in many other cities, air pollution can be derived from a diverse range of sources, but a major one is trash burning. In Indian cities, 50% to 90% of trash collected ends up in landfills. Burning is typically the only removal method available today, filling the air with toxic gases and harmful particles. They are facing a giant problem where they have created a system to counteract the garbage that is burned on large dumps, by educating people about the importance of recycling waste at source and offering door-to-door dry waste pick-ups. Since materials are recycled, they attack the problem from two different directions: first one being that materials are not burnt, and air pollution is not released into the air. The second is that recycling is so much better from an energy standpoint and it is even more important in countries where the energy comes from fossil fuels. In India, 75% of electricity comes from coal-fired power plants, which also emit huge amounts of air pollution.

The Solar Ironing Cart


There are about 10 million ironing carts in use in the streets of India. Together they use about 50 million kg of charcoal every day, consuming enormous amounts of wood, polluting the air and contributing to climate change. Vinisha recognized the need for a sustainable solution to the problem and created a solar powered ironing cart, an innovation that proves safer, healthier and more sustainable.


The jury's announcement:

With a smart design and a strong understanding of the problem of charcoal as an air pollutant, Vinisha has managed to combine science, innovation and technology to design and create the Solar powered ironing cart. If implemented on a large scale, this is an invention that can have a significant positive impact on India's air quality and people's health, while reducing unsustainable use of wood. The jury is impressed and sees a young scientist and entrepreneur with a strong passion for clean air that can bring multiple benefits to both society and the environment.

Shreya Ramachandran 2019

Fremont, USA

The Grey Water Project


Almost half the water used annually in a typical household–about 73 000 gallons–can be reused to water lawns and gardens. Shreya developed an innovative solution; The Grey Water Project and built her own grey water cleaning system with soap nuts–which makes grey water reusable. She now teaches others how to install their own systems and holds regular how-to workshops on water conservation and reuse.


The jury's announcement:

Water covers 70% of our planet. It's the source for life as we know it. And it's easy to think that it will always be there. But the fact is, only 3% of the water on earth is fresh water and many parts of the world still lack access to it. So why do we waste it? That was the problem Shreya Ramachandran set out to solve. Today, after years of hard work, she has come up with a ground-breaking technique to save grey water that comes from households to be reused for irrigation. At the same time her non-profit organization The Grey Water Project has taken on the tremendously important task to introduce kids in schools to the concept of water conservation. They do so with the purpose to make it as natural as reusing paper or plastic in our everyday lives. Basically, Shreya is working to save the source of life. What more can we ask from a young talented entrepreneur. Her work is of great significance today but will be even more important tomorrow as water scarcity continues to be one of the world's most important issues to tackle.
