GREENHOUSE GAS EMISSIONS
At the November 18, 2021 Board of Directors (Board) meeting, Board Member Lauritzen raised the issue
of staff investigating net zero, as it relates to climate change impacts. In response to this request, staff is
bringing this item to the Real Estate, Environmental and Planning Committee to have an initial discussion
before bringing this item to the full Board for next steps. Staff has prepared the attached presentation as
background to facilitate the discussion with the Committee.

WHAT IS NET ZERO?
Net zero refers to a state in which the GHG emissions going
into the atmosphere are balanced by removal out of the
atmosphere.
Generally, emissions are bounded by a `scoped' approach:
Scope 1 — direct entity -owned or controlled GHG emissions
occurring at the source;
Scope 2 — GHG emissions associated with the production of
energy consumed by an entity; and
Scope 3 — indirect GHG emissions associated with an entity's
activities from sources not owned or controlled by the entity.

EXPERT RECOMMENDATIONS ON HOW TO IMPLEMENT
There is strong international agreement across the climate
community that net zero targets should:
Include actions in all three scopes;
Reach net zero by 2050;
Set interim targets; and
Act immediately.

Opportunities
Central San has already taken some actions.
Moving away from our natural gas cogeneration system
would result in a dramatic reduction in Central San's
Scope 1 emissions.

POSSIBLE APPROACHES
Incorporate net zero into our Phase II
solids handling evaluation by Brown &
Caldwell (currently in process)
Develop a Climate Action Plan, as cities
have done to comply with Assembly Bill
(AB) 32 requirements
Commit Central San to net zero by 205C
and develop a roadmap accordingly
NEXT STEPS
Discussion with the full Board
Consultant evaluation?
Board workshop?
