We’ve all read about the perils of climate change, but who’s actually doing anything about it? In our Green Issue, we introduce leading figures who've made saving the environment their priority, whether it’s protecting Malaysia’s endangered tigers, establishing eco-focused political parties or investing billions of dollars in clean-energy initiatives. Below, meet the Hong Kong constituents:

Markus Shaw

Why him: Markus has dedicated his life to making Hong Kong an eco-friendly city, first as the chairman of WWF’s Hong Kong board, then as a co-founder of the NGOs Designing Hong Kong and the Clean Air Network, and more recently as chairman of the Walk DVRC project, which aims to turn traffic-choked Des Voeux Road Central into a pedestrian oasis.

Craig Leeson

Why him: Craig’s documentary A Plastic Ocean, hailed by David Attenborough as “the most important film of our time,” has raised awareness of the global plastic pollution crisis.
