Conclusion l.jpg

Conclusion

  • Tenants living in social housing already have a small environmental footprint

  • Units are relatively small and modest

    • One-bedroom seniors apartment is less than 500 square feet

  • With a reduction of 1,065 tonnes of green house gas emissions each year, and reduction of another 1,973 tonnes planned for next year, the environmental footprint of social housing gets smaller each year
