What Is Your What If London National Park City

What's Your What If?

The campaign for London to become the world’s first National Park City was the result of a wide-ranging, inclusive movement which worked across the city to build enthusiasm, excitement, and support for this radical new idea.

What is your What If? 

When we launched the Greater London National Park City Proposal in July 2015, it was built on a bold question: What if London were a National Park City? That spark has inspired countless others.

In her book Nature is a Human Right, Ellen Miles, alongside Dan Raven-Ellison, gathered a constellation of What If? questions from our supporters. These questions shimmer with possibility, and today many are already being realised by individuals, organisations, and local government across the capital.

Now, a decade on from that first audacious idea, we’re returning to you with a new invitation: What is your What If?

Are you ready to see the city with fresh eyes?

There are three kinds of What If? questions, each carrying its own weight and potential:

  • At the highest tier sits the visionary What If – the bold, horizon-shaping question that can define the very identity of a movement or organisation.
  • The second-tier What If narrows the lens, yet still carries a broad ambition. These are the questions that shape strategy within a particular sphere.
  • The third-tier What If – perhaps the most powerful of all. These are the catalytic questions that don’t just inspire lofty visions, but actively carve pathways to action.

Together, they form a layered architecture of imagination, designed not just to provoke thought, but to spark real change. We’ve selected four questions for you to explore that are now being brought to fruition.

What if
It was safe and easy to cycle everywhere?
What if
All citizens could get a licence to plant in public places?
What if
A tree was planted for every child born?
What if
Everyone could identify 10 trees, birds, wildflowers, and insects?

The London Charter

The Charter of the London National Park City is a collaborative document that sets out the collective ambitions, goals, and aims of the London National Park City movement. We are working together for better:

The Charter was signed by the Mayor of London and over 300 organisations at a ceremony’s celebrating the launch of London National Park City in July 2019.
