Scope 1&2 GHG Reduction Objectives for Aviation
and Maritime
Current                                   Proposed
15% below 2005 levels by 2020          15% below 2005 levels by 2020
50% below 2005 levels by 2030          50% below 2005 levels by 2030
Carbon neutral or carbon negative       Net Zero or better by 2040
by 2050

Net-zero: any carbon dioxide released into the atmosphere from a company's
activities is balanced by an equivalent amount being removed
Carbon neutral or carbon negative: emissions are offset with a reduction that
can include buying carbon offsets to make up the difference

14

Achieving Scope 3 Objectives for Aviation and
Maritime
Continue to advocate for strengthened tailpipe standards and
renewable energy production across maritime and aviation industries
Increase requirements for TNCs, taxis and expand to other ground
transportation providers
Continue to implement 2020 NW Ports Clean Air Strategy,
partnering with other ports and industry (e.g., Getting to Zero Coalition)
Continue to lead at both airport and seaport locations by installing
infrastructure for renewable fuels, electricity, and shore power

15

Recommend Accelerating GHG Targets
Responds to the urgency of the climate crisis
with more aggressive targets
Aligns with Washington state GHG targets
2040: 70% below 2005
2050: 95% below 2005 and achieve net-zero GHG
emissions
Builds on reduction initiatives already underway
to achieve the proposed targets
Affirms Port leadership on building the clean
energy economy and eliminating carbon
emissions
