Tools for a greener built environment

We build tools that help you understand and improve your local environment. See where nature is needed most. Map what's already there. Take action.


The problem

The built environment faces multiple challenges:

  • Insect populations down 60% since 2004
  • Air pollution causing 30,000+ early deaths per year
  • Urban heat islands 5-10°C hotter than countryside
  • Paved surfaces increasing flood risk
  • Construction damaging tree roots and reducing biodiversity

These problems overlap. The same solutions — trees, green space, better planning — can address several at once.

But environmental data is scattered. It's hard to see the full picture or know where to act.

We bring this data together into tools anyone can use.


How we work

We build small, focused tools. Each one does one thing well. Together they form a toolkit you can use to understand and improve your environment.

Mostly free

Most tools are free to use. They use public data from government and satellites. Some professional tools for developers are paid, which helps fund the free tools for communities.

Starting local

We're based in Bristol. We're building tools that work here first, then expanding to other cities. This helps us learn what actually works.


Who it's for

Councils

Find where to focus tree planting and green space projects. See which areas face the most challenges. Track what you've done.

Developers

Check environmental conditions before you build. Find sites that need biodiversity improvements. Show the benefits of your project.

Community groups

Map what's in your neighbourhood. Find spots for new trees or gardens. Get the data you need for funding bids.
