City of Raleigh GHG Projections (2007 - 2022)
With ALL100+Future StrategiesAdded
This reduction was accomplished with relatively low
capital expenditures, few impacts on City or
department operations or budgets, no increased cost
to customers, and no reduction in level of service to
customers. Many of these projects were already
underway prior to the Greenhouse Gas Emissions
Inventory for Municipal Operations being complete.
However, as Raleigh continues to grow at its
estimated rate of 2.5% per year, carbon emissions
from municipal operations will continue to grow as
well in order to provide the same level of services to
its new customers. Therefore, the impressive
achievements since 2007 will be eroded over time if
no actions are taken to achieve further reductions.
As shown in the graph, the City Operations carbon
emissions would eventually exceed the 2007 levels –
in Year 2017 – if no further reductions are achieved.
The Road Ahead
The CEAP process identified future
additional projects, strategies, and best
practices which, if all implemented, could
reduce emissions by about another 10%, at
an estimated capital cost of over $100 million.
If all the actions needed to obtain the additional
10%
decrease were implemented at one time
(
assuming in Year 2013 as shown in this
graph), continued City growth would
overtake this gain in Year 2020. Just to
overcome City growth, additional
actions to increase energy
efficiencies and reduce carbon
emissions annually by 2.5%
are needed in the future.

Projected Emissions for “Business-as-

By plotting ALL possible
strategies, the Team could
clearly see the practical
limits of carbon reduction
and develop fiscally
responsible targets
and expectations.
The chart below shows
a 20% reduction target is
not realistic given the limits
of current technology; costs to
achieve this 20% are estimated
to be in excess of $100 million.
