Peggy Liu – Chairperson, JUCCCE

Branded the ‘Green Goddess’ of China and named one of Time Magazine’s Heroes of the Environment, Liu is the Chair of Joint US China Collaboration on Clean Energy (JUCCCE), a non-governmental organization at the heart of the greening of China since 2007.

It is a leading catalyst of a more sustainable China and consults companies and governments on sustainability and cross-cultural collaboration. Liu’s influence is helping it  to achieve incredible milestones.

“What we need is 100 Peggy Lius all over the world. If that were to happen, we would be on the path to a sustainable society,” said Nobel Laureate Rajendra Kumar Pachauri, Former Chair of the Intergovernmental Panel on Climate Change.

Liu speaks internationally on lessons she learned in tackling China’s toughest environmental challenges: pollution, urbanization, epidemics, drought, obesity and diabetes. And she says there’s plenty to replicate.

“China is the country that is going green at the fastest scale, at the fastest speed. Nobody else can do it at this scale because China is led largely by engineers. China knows how to build infrastructure. So I think because of that, China can help the world go green,” she suggested when speaking on the Outrage + Optimism podcast .

He is the Founder of FluxGen Technologies, which has the goal of de-risking industries from water crisis, and The Sustainability Mafia, an organization aiming to multiply the impact of sustainability leaders through goal-oriented collaboration.

“The water crisis is a time bomb that can explode anytime – people are dying because of the unavailability of water and contamination, many industries will shut down, leading to mass unemployment, large-scale migration and political instability,” he wrote in an article.

“When my granddaughter, hypothetically, reads modern history it will most likely be about violence and wars fought associated with the water crisis. I believe we can avoid that history in making, by investing in water positive initiatives.”

Mun Ching Yap – CSO, AirAsia

Yap understandably refers to herself as a ‘sustainability champion and social enterprise supporter’, and she is certainly realizing her ambition to reshape how businesses contribute to society.

Florian Graichen – General Manager of Forests to Biobased Products, Scion

Alternative fuel sources are essential for the future and Graichen is responsible for Scion’s projects, programs and impact delivery around replacing petrochemicals, fossil fuels and other non-sustainable materials with products from trees and other biomaterials.

“Consumers are increasingly expecting manufacturers to switch from fossil fuel-based resources to renewable bio-based resources, and to adopt circular economy principles where materials are used and reused efficiently,” he said on the company’s website.

“Climate change, living beyond our means and population growth are truly global challenges. It affects all regions, people and economies across the world. Living outside planetary boundaries is simply not an option.”

With in-depth knowledge of biorefineries, biopackaging and circular manufacturing, Graichen encourages us to think about how we can use these to meet sustainability demands.

Nikita and Nishita Baliarsingh – Co-Founder and CIO/Co-Founder and CEO, Nexus Power

These twins are helping beat air pollution in two ways. Their technology to make energy storing cells from agricultural waste by applying a specialized extraction and filtering process means farmers no longer need to burn their fields after harvest. And the resulting lithium-free and biodegradable batteries can be used in electric cars.

“Made out of biodegradable material, the cells rule out toxicity hazards, and using crop residue ensures that some of it is not burnt, which in turn protects from deterioration of air quality. Our entire process is energy efficient and sustainable,” Nishita told Life Beyond Numbers.

The batteries charge eight-to-10 times faster and last 20–30 percent longer than their lithium counterparts, solving one of the environmental issues of electric vehicle transport.

Lynn Loo – CEO, Global Centre for Maritime Decarbonisation

The Global Centre for Maritime Decarbonisation is a not-for-profit organization set up to accelerate international shipping’s transition to a low-carbon future – “one of the most urgent challenges of our generation,” Loo says.

In 2017, she co-founded Andluca Technologies, a startup developing wireless smart window solutions to increase the energy efficiency of buildings and improve occupant comfort.

“No man is an island; I try to surround myself with smart people whose perspectives are different from mine and in so doing, build strong and resilient teams,” Loo said on LinkedIn.

Her posts give a very personal, human perspective and break down complex data to make it more understandable.
