SQUARE FEET OF GREEN ROOFS BUILT EACH YEAR
TWO GREEN ROOF MARKET PENETRATION SCENARIOS FOR NYC
These scenarios represent realistic and achievable goals for building green roofs on a scale where they can be a meaningful part of
an urban climate change mitigation strategy. GRHC's corporate
members alone have installed between 650,000 and 1.6 million sq.
ft. every year for the previous five years in the leading metro area
each year. The NYC metro has not led for any of those years -
the list is dominated by cities like Washington, DC and Toronto,
which have more robust green roof policies.
Existing green roof policy in NYC is largely limited to two
programs: The first is the Department of Environmental Protection's Green Infrastructure Grant Program, which has seen low
uptake, funding only 278,000 sq. ft. of green roof area since 2011,
just over 30,000 sq. ft. annually.
The second program is the Property Tax Abatement, which
began at $4.50/sq. ft., was increased to $5.23/sq. ft., and is proposed to increase to $15/sq. ft. for certain areas of the city (see
page 28). This increase is welcome, but the program spending is
currently capped at $1 million a year over four years, supporting
only about 66,667 sq. ft. of green roof area annually.
Trends show that NYC's existing policies are inadequate to meet the
LIVINGARCHITECTUREMONITOR.COM
targets necessary to address the climate crisis. The Green Infrastructure
Grant and Property Tax Abatement Programs together are likely to
incent less than 100,000 sq. ft. of green roof annually. This represents
only 13.8 per cent of realistic 2020 targets, and only 0.6 per cent and
0.37 per cent of the 2050 targets for the two different scenarios.
The Green Infrastructure Grant Program has recently been
updated and a third party has been contracted to help deliver the
program, which should help with its uptake. For the Property
Tax Abatement to be an effective contributor to the targets established, the annual program cap will need to be increased.
Despite their current limitations, improvements in these policies, along with mandatory green roof requirements passed in
2019, suggest that the area and number of green roofs in NYC will
increase. However, the market impact of these policies remains to
be seen, and more aggressive action may be needed for green roofs
to meaningfully contribute to NYC's climate mitigation efforts.
