Our Ambassadors

Green Monday ambassadors support the mission of Green Monday and they enthusiastically promote the benefits of going green to the public.

Mary McCartney

Global Mission Ambassador

Mary is an internationally renowned photographer and co-founder of “Meat Free Monday”. She was fascinated by the fact that Green Monday shared the same values with Meat Free Monday in championing a sustainable and compassionate food system. She has therefore teamed up with Green Monday to form a global alliance to champion the plant-based movement.

Karena Lam

Greater China Ambassador & Chief Eco Curator

Golden Horse award-winning best leading actress Karena Lam is passionate about promoting a plant-based diet to combat the climate crisis. In light of the deteriorating state of the planet, Karena often addresses global climate issues on social media and participates in eco-friendly initiatives, in hopes of mobilising the public to play their part.

Kay Tse

Chief Kindness Officer

Kay is a well-known Cantopop singer from Hong Kong and her music touches on a broad variety of subject matters including social issues in Hong Kong. She has been actively involved within many charitable and philanthropic initiatives, including Cancer Fund, World Vision and Habitat for Humanity. Kay is deeply concerned about climate change and the environment, devoted to advocating eco-friendly living to the public.

Establishing a global alliance by teaming up with Green Monday is a big and crucial step forward. It’s not just me with Meat Free Monday in the UK and David with Green Monday in Hong Kong. We need to team up. It’s a global awareness campaign.

Mary McCartney

Global Mission Ambassador

My shift towards a plant-based diet may not be too impactful to mitigating climate change, but I believe individual power and influence of being vegetarian on ‘one day per week basis. Simply phasing out meat, it has positively influenced my diet, consumption habits and wellness. I see a smooth transition towards a vegetarian diet, even though I was a meat lover

Karena Lam

Greater China Ambassador

We see hope in options to a desirable plant-based diet for people and a more eco-friendly lifestyle, an elevated standard of living; that is not only preferable to the people who pursue it but also the people around them and the environment in an overall sense. Instead of asking myself why (change), I’m rather thinking Why Not?
