Grow Nature-Based Social Value in Camden.
Carbon Heroes is Camden's specialist partner for helping suppliers deliver robust, measurable nature-based social value through tree sponsorship — fully aligned with the Good Life Camden framework.
Why Camden x Carbon Heroes?
Camden Council expects strong, mission-aligned social value on large contracts, with a commonly applied minimum 10% weighting in tender documentation.
Carbon Heroes was appointed to help suppliers deliver this nature-based and community value through urban greening sponsorship in the borough — turning Camden's tree strategy into a simple, scalable social value offer.
- The Good Life Camden framework puts Safety, Equality, and Health at the heart of social value.
- Carbon Heroes directly supports this by funding tree planting and maintenance, delivering clean air, climate resilience, health and wellbeing, and stronger community participation around local green spaces.
- All activity is measured and reported against Camden's own social value criteria.
How the Partnership Works.
Step 1
You Sponsor Camden Trees
Choose a mix of:
A. Planting of 1 New Tree
Best for: Highest social value delivered. New planting to support Camden's climate and biodiversity goals; precise tree and location allocated.
B. Yearly Aftercare of 1 Young Tree
Best for: Council and residents visibility. Funds the critical early-years maintenance of a young tree; precise tree and location allocated.
C. Yearly Mature Tree Welfare
Best for: Social Value ROI. Contributes to the care of Camden's existing tree stock via pooled fund. Includes ongoing and special welfare measures like vertical mulching.
Step 2
Carbon Heroes Does the Maths
- We use Camden data and national social value standards to value each tree's environmental and health benefits.
- We convert those benefits into £ social value and PPN 002 metrics (CO₂e stored, pollution removed, m² greenspace).
- We maintain a central registry of sponsored trees and manage reporting for the council.
Step 3
You Plug the Results Into Your Bid
Your sponsorship plan and metrics feed directly into Camden's Social Value Matrix, especially under: Clean, vibrant, and sustainable places.
