Sustainable property development

With more than 100 sustainability indicators on environmental sustainability, social impact, and economic development, the SDF represents one of the most comprehensive and results-focused frameworks of its kind in the world.

We created this metric-driven tool to help us become London's leading sustainable developer, resulting in high-impact projects for the public good.

In 2020 GRESB, the industry's leading international sustainability benchmark, recognised TfL as a leader in sustainability, in part because of the SDF. We received a GRESB 5 star rating, the highest possible and an outstanding achievement for a first time entrant.

How we make a difference

Reducing carbon emissions

Across our development portfolio, we're reducing our operational carbon emissions by 47.6% compared to building regulations - and well in excess of the 35% reduction required by the London Plan.

Promoting biodiversity

On average, our sites are delivering 590% biodiversity net gain, helping to support London's urban ecosystems.

Greening London

Our projects seek to intensively green the urban environment. We have achieved an average Urban Greening Factor of 0.36 across our portfolio.

Home Quality Mark

Our robust sustainability approach means we have achieved an average Home Quality Mark (HQM) rating of 4 Stars across our portfolio, with 45% of our schemes at 4.5 Star - the highest ever level of certification in the UK to date.

As part of our development programme, we have set up a series of construction skills training academies. These have seen 2,429 apprentices trained for skilled construction work, with 78% of trainees coming from unemployment.

Creating jobs

Through our construction skills programme, 791 trainees directly entered employment as a skilled construction worker.

Diversity in employment

Within our construction skills programme, 65% of participants are from ethnic minority backgrounds and 8% have a learning difficulty or disability.
