A climate action plan (CAP) is a set of strategies that guide efforts
for climate-change mitigation. Many CAPs have recently been developed by cities,
states, nations, companies and organizations. In fact, the Zero Energy
Project currently lists
414 cities and counties as having such plans.
Despite these numerous commitments, the global greenhouse gas (GHG) emissions
picture is alarming. After a 5.8 percent decline in 2020 due to
COVID, GHG rebounded
4.8 percent in 2021, leaving us almost exactly where we were. With further
growth in GHG emissions in 2022, we will reach yet another all-time high and the
planet will be heading for climate catastrophe. How do CAPs relate to design of
the built environment, and are they a useful tool in achieving real GHG
reductions?
The City of Denver, where I work, adopted a CAP in 2018. The City’s goals
are 40 percent GHG emissions reduction by 2025, 65 percent reduction by 2030,
and 100 percent by 2040. Denver has chosen to concentrate on four priorities:
-
Optimizing energy efficiency in buildings
-
Decarbonizing the electricity grid
-
Enabling next-generation mobility
-
Improving waste management
The largest-scale governmental entity of all, the UN Secretariat, published
its
CAP
in September 2019. The plan commits the organization to ongoing climate
neutrality for its global operations. Its three priorities are intensification
of existing efforts, innovation and outreach.
The American Institute of Architects (AIA), of which I’m a member,
declared an urgent climate imperative for carbon reduction in July 2020. As the
largest design-focused organization in the world, the AIA has established three
clear, simple goals for its members:
-
Mitigating the sources — Establish the relevance and importance of the
building sector and architectural practice in climate mitigation solutions
-
Adapting to the impacts — Design buildings and communities to anticipate and
adapt to the evolving challenge of climate change
-
Catalyzing architects to act — Lead meaningful change and contribute to
climate solutions in partnership with our global community
Cities, states, countries and other governmental organizations are not alone in
adopting CAPs; private
companies
and publicly held
corporations
have kept up. It is hard to find a company that does not have stated goals
around environment, climate or carbon emissions. Fewer companies, however, have
fully developed CAPs — especially those using science-based
targets.
And many that do have CAPs struggle to make serious reductions in their actual
GHG emissions, as opposed to simply buying
offsets.
Starting with measurement and assessment
Most CAPs start with an objective review of GHG emissions, subdivided into the
now well-understood Scopes 1, 2, and 3. A brief recap of the Scopes is:
-
1 – GHG emissions directly from operations that are owned or controlled by
the reporting company
-
2 – Indirect GHG emissions from the generation of purchased or acquired
electricity, steam, heating, or cooling consumed by the reporting company
-
3 – All indirect
emissions
(not included in scope 2) that occur in the value chain of the reporting
company, including both upstream and downstream emissions.
Most companies measure and seek to reduce their scopes 1 and
2. For typical
companies, the majority of scope 1 emissions will be natural gas used in
buildings or fuel for vehicles. The majority of scope 2 emissions is typically
electricity used in buildings. The key word in the scope 1 definition is
“control.”
To what extent do reporting companies that are tenants in a commercial building
control the use of natural gas for space and water heating? They may be able to
change thermostat settings or reduce hot water use; but they do not select and
maintain the equipment that burns that gas, nor do they design the walls and
windows of that building that determine heat loss. A reporting company that
seeks to reduce its scope 1 but does not own its own buildings has limited
influence. The best option in that case may be to request utility data when
leases are being negotiated and seek buildings with more efficient operations.
Once a company has completed a GHG assessment, the more challenging concern is
which targets to set and how to achieve them. Most companies align their targets
with one or more national or international standards and usually seek to achieve
them by the end of a decade. A well-known corporate goal is Microsoft’s
ambition
to be carbon negative — including offsetting all of its past emissions — by
2030.
Science-based targets
The Science Based Targets initiative
(SBTi) is an independent organization that
assists the private sector by setting and achieving science-based GHG emissions
reductions. Its partners include the UN Global Compact, the World
Resources Institute, World Wildlife Fund, and the
CDP.
SBTi offers guidance to companies based on the size of the organization and the
type of the business. For large companies with a significant global impact, this
is a great option to consider. Smaller companies may not find the SBTi a good
fit — opting instead for a simpler approach in which they calculate their own
Scopes 1, 2, and 3 GHG emissions; or hire a consultant to assist them in this
task, and then set their own targets.
Fortunately, standards for GHG emissions calculations are well-established and
many consultants offer such services. In our experience, the tougher challenge
is how to proceed from knowing the emissions profile to crafting a CAP to reduce
them. Companies can develop strategies to reduce their Scope 1 and 2 emissions
over time, and many are doing so.
Scope 3 challenges
Scope 3 is more
difficult
because it is not under the company’s direct control. Scope 3 emissions are
typically generated by a company’s suppliers through its use of goods and
services from other companies. Examples are air travel, cleaning supplies and
merchandise. One company’s Scope 3 emissions are another company’s Scope 1 and
2. Scope 3 is important because these emissions can represent as much as 80
percent of a company’s total GHGs.
Companies with significant clout, such as
Walmart,
can exert pressure on suppliers to reduce their emissions and thus their own
Scope 3 emissions; but most smaller players lack the leverage to effect such
change. Smaller companies should ask potential vendors for emissions profiles
and select them based on this criteria. Over time, this approach — if adopted by
enough companies — will reduce global emissions through the power of the
“invisible hand” of the market.
Cuningham’s experience
At Cuningham, we have been calculating our Scopes 1
and 2 — and much of our Scope 3 emissions — since 2018. We saw it fall
dramatically during COVID and are estimating the degree to which it will
increase again in 2022. In this timeframe, we have implemented minor reductions
and offsets. We expect our GHG emissions to stabilize at approximately 3.66
metric tons CO2e per employee per year. The chart below illustrates the GHG drop
due to COVID and our expected rebound.
Our science-based target is to reduce our emissions from that 2022 benchmark
year over year until we reach net-zero carbon for our internal operations by
2030 — we believe that is the latest year to reach net
zero
that provides a realistic chance of limiting global temperature rise. We need to
reduce our footprint by 12.5 percent per year until 2030. Key strategies in this
effort will be:
Even as we reduce GHG emissions from internal operations, we will use offsets to
reduce our carbon footprint more rapidly. Offsets are complicated and
controversial;
there is much concern that over-reliance on offsets leads to lack of real
progress.
We recommend companies carefully consider the options. After much research,
Cuningham is pursuing this blend of offsets to reach net-zero carbon impact
sooner than 2030:
-
Airline offsets for air travel
-
Uber Green and/or
Lyft
for rideshare services
-
National Car Rental LEV use
-
Planting trees at our project sites to offset paper use
-
Installing solar panels at our projects to offset office utility use
-
Investing in a reputable offset company such as Climate Vault for
remaining GHGs.
Cuningham will monitor the effectiveness of each of these reduction and offset
strategies and refine our CAP every year. We strongly believe that we can
achieve net-zero carbon for our internal operations well before 2030, and remain
hopeful to make it happen sooner.
