From YouTube: Using Digital Credentials for a Carbon Accounting Pilot
Description
A guest presentation at the Hyperledger Climate Action and Accounting Special Interest Group on October 4, 2022 featuring Nancy Norris: Senior Director - ESG & Digital Trust, B.C. Ministry of Energy, Mines and Low Carbon Innovation and Kyle Robinson: Senior Strategic Advisor, Digital Trust Ecosystems.
In this session, Kyle Robinson and Nancy Norris discuss how the Government of British Columbia’s Energy & Mines Digital Trust’s carbon accounting pilot enables a collaborative digital ecosystem between the B.C. government, natural resource companies, and organizations around the world using digital credentials. This discussion details how the pilot has informed governance structures that support adopting a digital trust ecosystem at scale to facilitate the safer and easier exchange of transparent sustainability data.

Okay,
welcome
everybody!
I'm
very
excited
about
today's
presentation,
with
the
BP
minds
of
energy
in
the
digital
Trust,
on
using
digital
credentials
for
carbon
accounting
pilot
I've
got
a
couple
of
housekeeping
things
that
I
wanted
to
share
with
the
Sig
before
I.
Do
that
I
wanted
to
flag
that
this
is
the
hyperledger
does
follow
the
Anti-Trust
and
address
policy
if
you
are
unfamiliar
with
that,
please
take
a
look
at
the
bottom
of
the
meeting
page.

A
Hi
I'm
new,
my
name
is
Brandon
I'm
I'm,
a
PhD
student
at
Northern,
Arizona
University
I,
come
from
the
carbon
accounting
world.
I
was
a
corporate
greenhouse
gas
accountant
for
about
five
years,
and
now
I'm
researching,
yeah
and
I
saw
a
lot
of
really
interesting
stuff
through
those
through
those
years,
but
but
really
just
a
lot
of
opportunity
to
improve
the
carbon
accounting
space.
So
I
came
back
to
Academia
to
research,
really
just
best
practices
in
carbon
accounting
and
opportunities
to
accelerate
decarbonization
with
better
Data
Systems.
A
Thank
you,
hey
I'm
new
as
well.
My
name
is
I'm.
Sorry,
my
name
shows
differently,
because
I
guess
I
slogged
into
the
wrong
Google
account
I'm
an
architect
at
IBM
I've
been
working
in
the
blockchain
space
for
a
long
time
and
I,
occasionally
pop
into
some
of
these
apologicals
I
found.
This
call
very
interesting,
so
I
just
thought
I
should
totally
listen
in
for
sure.
Okay.
A
Excited
to
be
here,
hi
everybody-
this
is
Tom
basor,
another
newcomer
to
the
group
coming
to
you
from
Florida
I'm,
an
attorney
privacy
Advocate,
recently
became
very
interested
in
SSI.
The
identity
space
was
happy
to
meet
Kyle
and
Nancy
in
Dublin,
at
the
hyperledger,
an
open
source
Summit
and
just
looking
for
ways
to
get
involved
and
acting
as
a
sponge
here
today
trying
to
learn
as
much
as
I
can.
So.
Thank
you
for
the
welcome.
D
A
A
Hi
also
I'm
new
here
foreign,
also
in
the
blockchain
area
since
around
four
years
and
the
carbon
issue.
It's
an
interesting,
interesting
research
for
our
site,
especially
manufacturing
area,
where
I'm
coming
from
so
from
especially
vulnerable
Bosch
from
Germany
side
I'm
interesting
to
see
about
the
project.
A
This
is
Dave,
I,
don't
know.
If,
hopefully
you
guys
can
hear
me
I'm
coming
from
the
Legacy
software
space
for
greenhouse
gas
emissions
and
broader
ESG
and
EHS
reporting
I've
been
in
kind
of
blockchain,
the
last
four
or
five
years
trying
to
identify
good
opportunities
to
overlap
credentials
and
the
decentralized
identity
space
into
ESG
and
EHS.
So
happy
to
be
here.
B
A
D
So,
possession
that
why
I
haven't
been
in
this
school
I
suppose
first
time,
but
we
have
been
cooperating,
something
not
with
the
Avenue,
so
Avenue
Miss,
some
somehow
related
to
the
SSI
question
and
this
carbon
accounting.
This
is
now
in
Europe
or
in
the
Nordic
countries,
Finland
Sweden,
Norway,
Iceland
and
Denmark.
We
are
at
the
moment
discussing
how
to
share
it
with
open
People
documents
like
catalog
or
open
People,
Base
building
invoices
or
then,
of
course,
this
interest,
because
this
is
a
little
bit
more
modern
Than
People
documents.
B
Okay
is
that
it
I
think
that
is
it
okay,
so
I
will
go
ahead
and
move
forward.
Just
a
couple,
quick
announcements.
One
thing
I
wanted
to
share
is
the
climate
action.
Accounting
Sig
is
in
the
very
early
stages
of
discussing
developing
a
project
with
an
hyperledger
based
on
some
of
the
work.
That's
been
done
around
this
concept
of
the
measurement
economy.
B
This
is
an
idea
that
is
kind
of
being
spearheaded
by
a
couple
different
maintainers
within
the
tig.
The
idea
is
to
develop
essentially
a
more
efficient
Marketplace
for
supply
chain
emissions
data
by
and
and
it's
using
hyperledger
and
different
tools
to
pull
carbon
emissions,
verify
it
and
certify
it
for
use
by
state
actors,
consumers
and
green
Finance
in
order
to
just
speed
up
and
better
incentivize
the
adoption
of
decarbonization
technology.
B
So
more
on
that
to
come,
I
did
want
to
flag
that
for
the
Sig,
where
the
process
kind
of
putting
together
the
proposal
and
we'll
be
circulating
that,
with
with
different
stakeholders
before
taking
it
to
the
technical
steering
committee,
so
exciting
news,
there
I
also
wanted
to
very
quickly
flag
some
research
projects
that
we
have
coming
down.
The
pipeline,
or
actually
their
active
research
projects
that
we
are
recruiting
for
right
now
and
this
is
going
to
be
part
of
our
cop
27
engagement
strategy.
B
One
of
them
is
just
a
basic
competitive
analysis
of
the
different
tools
that
are
being
used
to
track
emissions
through
Supply
chains
and
then
also
for,
for
example,
the
green
Finance
Marketplace
to
track
and
understand
the
impacts
of
their
investment,
so
kind
of
both
sides
of
of
the
equation.
So
we
want
to
understand
what
tools
are
currently
being
used.
B
You
know
how
consumer
demand,
how
government
regulation,
for
example,
a
cost
of
carbon
and
and
some
of
these
different
incentives
can
affect
the
validity
of
adopting
different
Technologies
for
for
methane
emission
reduction
in
oil
and
gas
supply
chains.
So
we
are
interested
in
connecting
with
universities
with
different
corporations
with
some
different
think
tanks.
Anybody
who
has
an
idea
of
somebody
who
might
be
interested
in
this
type
of
work,
please
share
them,
share
them
with
us.
B
B
We
will
have
two
members
attending
Robin,
Clements
and
myself,
we'll
be
attending
cop
27
in
charmel
Sheikh,
and
one
thing
that
we
have
discovered
is
that
their
our
success
on
achieving
our
objectives
will
depend
a
lot
on
our
ability
to
kind
of
Outreach
do
some
Outreach
ahead
of
time
and
make
connections
so
that
we
can
kind
of
meet
with
people
in
this
very
kind
of
large
chaotic
environment.
So
we
have
two
lifts
here
for
the
igos
and
ngos
that
are
attending
and
would
love
any
big
support.
B
So
this
is
a
really
interesting
introduction
for
us
all
to
see
the
real
world
applications
where
the
rubber
is
really
hitting
the
road
and
some
of
the
challenges
and
solution
to
Kyle,
Robinson
and
Nancy
are
coming
up
with,
as
as
they
introduced
digital
credentials
into
kind
of
real
world
working
environment.
So
without
taking
up
too
much
more
time,
I'm
just
going
to
go
ahead
and
pass
this
over
to
them
to
give
them
as
much
time
as
possible.
So
stop
sharing
my
screen
now
and
Kyle
and
Nancy
very
much.
E
E
This
pilot
that
we're
working
on
through
the
energy
and
Minds
digital
trust
is
taking
that
concept
and
applying
it
at
the
organizational
level
specifically
to
mining.
A
natural
gas
operators
within
British
Columbia,
and
what
we're
trying
to
do
is
build
an
ecosystem
of
actors
that
can
share
information
about
their
sustainability
performance
in
British
Columbia.
We
have
very
strong
climate
legislation
that
all
of
our
large
emitters
must
adhere
to.
E
E
Great,
so
I
don't
need
to
sell
this
group
on
open
source,
but
we
are
very
committed
to
building
the
software
in
the
open
source
World
using
Open,
Standards
software
and
open
web
governance
for
multiple
reasons.
The
first
is
that
what
we're
trying
to
do
is
the
technology
that
we're
building
is
all
around
the
sharing
of
information
and
in
order
to
do
that
in
order
to
have
as
many
participants
in
the
ecosystem
as
possible,
we
want
our.
E
The
open
source
World
provides
a
really
amazing
Network
factors
for
us
to
learn
about
because
involved
with
and
test
interoperability
with.
The
other
is
that
it's
an
incredible
feedback
loop
for
us
in
terms
of
the
software
we're
building
and
whether
or
not
it
functions
for
other
governments
trying
to
do
the
same
thing.
We
were
recently
at
a
conference
in
Dublin
the
hyperledger
global
forum
and
found
out
that
the
UN
and
the
government
of
Rhode
Island
are
using
software
that
BC
contributed
to
the
open
source
world.
E
E
We
wanted
to
focus
our
pilot
on
making
that
process
more
efficient
for
operators
for
many
different
reasons,
but
one
of
which
is
that
we
believe
that
British
Columbia
operators,
because
they're
held
to
a
higher
standard
that
they
have
information,
that's
useful
for
potential
investors
for
potential
purchasers
for
voluntary
carbon
accounting
schemes,
and
we
want
to
since
they're
already
collecting
that
data.
We
want
to
give
them
the
opportunity
to
share
it
with
as
many
different
parties
as
possible
and
using
digital
trust.
Technology
makes
that
process
more
efficient.
E
It
increases
trust
and
security
and
the
information
that's
being
passed
along
and
then
there's
also
a
function
called
selective
disclosure.
We
have
mapped
a
process
that
is
a
it's
a
regulatory
process.
So
it's
a
very
like
it
is
a
very
intense
there's,
a
lot
of
different
data
that
is
being
collected
by
these
operators
using
digital
credentials,
they're,
actually
able
to
select
the
information
that
they
want
to
share
with
particular
audiences.
E
E
So
in
terms
of
key
terms
and
Concepts
digital
credentials,
I
imagine
this
group
is
pretty
familiar
with
that
concept.
That's
you
know.
In
the
individual
space
it
could
be
a
driver's
license,
a
passport,
it's
creating
a
digital
version
of
a
credential
physical
credential
in
the
real
world
for
us
that
sustainability
reports
for
our
pilot,
digital
trust.
E
This
is
enabled
by
the
technology
that
we're
using
being
able
to
track
who
the
issuer
of
the
credential
is,
who
is
has
consumed
or
the
holder
of
that
credential
and
then,
who
is
interested
in
that
information?
That's
the
verifier
of
that
credential
so
that
process
and
that
those
exchanges
of
information
are
recorded
in
the
distributed
Ledger,
and
so
that
information
is
publicly
available
bullet
is
increases
the
trust
in
terms
of
what
transactions
have
been
made
and
who
is
involved
in
the
ecosystem.
E
That
is
a
we're
using
hyper
Ledger
Indian
Aries
to
to
build
the
software,
which
kind
of
will
get
into
a
little
bit
more
later
in
the
presentation
and
the
governance
Frameworks
that
we're
developing
for
each
of
the
credentials
that
were
piloting
this
is
it
the
rules
and
terminology
and
the
info.
Basically,
the
the
in
government
speak.
E
E
One
anecdote
is
that
mining
operators
in
British
Columbia
have
to
submit
their
ght
reports
for
every
single
asset,
so
every
single
mindset
has
to
have
their
on
an
annual
basis.
They
have
to
report
on
their
emissions
in
order
to
input
that
into
the
regulatory
reporting
system.
At
the
moment
they
have
to
fill
out
a
web
form
with
I,
don't
even
know,
maybe
two
two
to
five
hundred
different
fields
of
information
for
every
single
line,
so
a
small
mine,
that's
or
like
one
mine
site:
okay,
that's
not
efficient,
but
it's
I.
E
So
our
Pilots
at
the
moment
in
the
pilot
will
be
showing
you
today
is
around
greenhouse
gas
reporting
for
mines.
We're
also
going
to
be
doing
a
similar
pilot
for
the
natural
gas
operators
in
British
Columbia
and
we're
working
towards
also
doing
a
credential
that
is
called
a
toward
sustainable
mining.
E
So
this
is
a
protocol
that
was
developed
by
the
mining
Association
of
Canada
I'm
internationally
recognized,
and
it
covers
off
not
only
the
E
that
you
know
of
the
ESG,
but
it
looks
at
multiple
different
factors:
not
just
carbon
emissions,
but
also
environmental
performance
of
a
mind.
Environmental
impacts,
their
relationship
with
the
community
that
they
operate
within
and
then
their
cups
so
being
able
to
have
a
digital
credential.
E
That
is
that
encapsulates
the
performance
of
a
mind
based
on
the
towards
sustainable
mining
protocol
is
another
very
valuable
piece
of
information
that
we
can
or
that
the
the
technology
can
allow
the
mind
to
hold
as
a
digital
credential,
and
then
they
can
share
that
information
with
couple
different
audiences
that
are
interested
in
that.
Having
that
information
about
the
Mind
proven
out
and
trusted.
E
C
Time
great
thanks,
Nancy,
so
yeah
we
did
do
a
presentation
back
in
March
to
this
group
and
we've
done
a
lot
of
work
since
then.
Went
to
the
global
forum
learned
a
bunch
more
things.
So
one
of
the
things
to
kind
of
that
we
learned
sort
of
in
the
last
few
months
was
original
presentation.
We
had
the
BC
government
climate
action
Secretariat.
C
So
now
we
have
our
actors
in
the
correct
roles
for
this
pilot.
We
also
found
out
that
the
credential
that
we
were
looking
at
doing
was
actually
something
very
specific
in
regulation.
It's
called
a
verification
statement
that
phrasing
of
verification
is
not
the
same
phrasing
as
a
verifier
in
our
typical
trust
triangle,
but
this
is
a
third
party
verifier.
So
this
is
the
one.
C
The
company
who
looks
at
a
mine
site
reviews
their
car,
Urban
accounting
information
and
then
verifies
that
information
once
they're
done
that,
then
they
can
issue
a
credential
to
the
mining
company.
So
that's
one
part
of
the
credential.
The
other
factor
for
that
was
it
wasn't
specific
to
mining.
It
was
actually
for
any
industry
in
British,
Columbia
or
any
any
emitter
actually,
but
typically,
industry
is
the
one
who
is
emitting
more
than
25
000
metric
tons
of
co2e
a
year,
which
is
where
the
regulation
Falls
for
needing
verification
of
that
information.
C
So
it
actually
kind
of
helped
Focus.
You
know,
looking
at
the
business
process,
helped
us
focus
on
what
we
what
we
needed
for
the
credential
and
for
the
process
who
needed
to
do
the
exchanges
and
then
the
last
thing
was
our
Readiness
on
just
you
know,
getting
ready
to
do
that
to
ghg
use
case,
and
so
we
actually,
you
know,
worked
with
our
partner
of
ours,
Northern
block
to
actually
get
something
working
in
a
in
a
pilot
sense.
C
F
F
F
F
Annually,
pricewaterhousecoopers
verifies
Copper
Mountain
Mining
corporation's
legislatively
required
greenhouse
gas
emissions
data.
Thank
you.
Having
verified,
copper,
Mountain's
data
PWC

PWC
inputs,

Requires
mining
companies
that
emit
over
25
000
tons
of
co2e
a
year
to
report
their
ghg
emissions
annually,
adhering
to
the
greenhouse
gas
industrial
reporting
and
Control
Act
using
traction.
The
climate
action
Secretariat
can
see
that
Copper
Mountain
has
sent
their
digital
credential
Cass
has
the
ability
to
see
that
pricewaterhousecoopers
verified
this
data
and
issued
the
digital
credential
Cass
still
reserves
the
right
to
check
emissions
reports
for
accuracy.

This
demonstration
is
one
of
several
emdt
Pilots,
exploring
how
sustainability
reporting
can
be
made
more
efficient
in
the
natural
resource
sector,
contact
Energy
in
mind's,
digital
trust,
to
learn
more
and
to
watch
a
live
demonstration
of
a
credential
Exchange.
This
demonstration
uses
traction
and
Northern
block
technology.
C
All
right,
so
that's
a
quick
video
I
just
saw
some
things
in
the
chat.
So,
yes,
we'll
do
questions
at
the
end
and
this
presentation
will
be
available
after
if
you
check
the
meeting
page,
the
link
to
this
video
that
we
just
saw
is
also
there
on
this
diagram.
This
is
our
our
basic
diagram
for
our
pilot.
C
What
we
saw
in
that
video
is
these
top
three
boxes
so
pricewater
host
Coopers
is
our
issuer
they're
issuing
a
credential
which
is
a
greenhouse
gas
emissions
report,
verification
credential
they're,
issuing
that
credential
to
one
of
our
pilot
Partners
Copper
Mountain,
Mining
Corporation.
They
run
a
large
copper
mine
facility
in
the
interior
of
British,
Columbia
and
they're,
presenting
that
information
in
the
video
as
a
presentation
proposal,
and
so
that's
our
planned
process
there
to
The
Climate
action
Secretariat
where
they're
going
to
receive
the
information
review.
C
But
what
they
can
do
with
those
credentials
is
they
can
use
just
a
subset
of
data
for
a
voluntary
process,
whereas
they
can
use
all
of
the
data
that's
required
for
the
regulatory
process.
So
maybe
just
the
total
number
of
emissions
for
the
year
goes
to
open,
Earth
and
then
the
breakdown
of
all
the
different
gases
and
all
the
different
pieces
would
go
into
the
climate
action
Secretariat.
C
C
Our
piece
is
traction
which
actually
runs
on
top
of
acupai,
so
it's
running
areas
as
well,
and
so
that's
an
instance
that
we
have
running
in
a
test
environment
on
our
government
servers
open,
Earth
they've
got
their
own
instance
of
acupai
they've
been
doing
a
lot
of
work
with
indicio
for
their
implementation.
Again,
it's
Aries,
and
so
the
interoperability
is
very
important
as
well.
Even
though
there's
three
different
instances
of
Aries
here,
I
guess
they're
all
occupy
and
then
but
interoperable
is
the
goal
here,
foreign.
C
Now,
we're
still
to
be
seen
where
that
develops,
but
that
that's
sort
of
the
goal.
Right
now
and
in
our
pilot
example,
the
climate
action
Secretariat,
is
one
entity
inside
BC
government.
There
are
many
many
other
entities
but
we're
using
the
climate
action.
Secretariat
there's
a
couple,
others
that
we're
working
with
as
well
early
stages.
C
Let's
see
we
were
we
built
the
traction,
this
controller
piece
as
an
API
first
architecture.
The
reason
we
did
that
was
because
a
lot
of
these
entities
in
government
or
even
in
the
in
private
sector
have
existing
systems
that
they
want
to
integrate
with.
So
they
want
to
they've
got
their
own
system.
They've
spent
millions
of
dollars
building
it.
They
don't
want
to
have
to
rebuild
something
or
or
take
on
something
new.
C
So
we
built
that
API
first,
so
they
could
do
some
integration
into
their
own
system
to
allow
them
to
do
again
issuing
clothing,
verifying
in
the
in
the
Indie
World
Aries
world.
There's
connections
as
well
even
basic
messaging,
there's
a
lot
of
different
mechanisms
that
they
can
use
to
do
transactions
with
other
other
businesses,
other
governments
or
even
citizens
yeah.
So
that's
probably
good
on
that
slide.
C
So
the
other
thing
that
we've
been
working
with
is
the
trust
River
IP
foundation
and
for
those
who
live,
familiar
I,
know
Eric
you're
very
familiar
with
this.
The
trust
over
IP
has
a
two-sided
stack
on
the
left
hand.
Side
is
the
technology
stack
on
the
right
hand,
side
is
the
governance
stack
and
we've
been
spending
a
lot
of
time
working
on
our
governance
stack
with
the
goal
for
this
pilot
to
actually
become
a
production
system.
E
E
E
Thank
you
great
yeah.
So,
of
course,
if
you're
interested
in
more
information,
please
reach
out
we're
always
happy
to
chat
and
talk
more
about
the
project,
we're
both
pretty
passionate
about
it.
So
it's
one
of
my
favorite
topics
and
also
I
folks,
have
questions.
I.
Think,
there's
some
time
now
in
the
schedule
to
to
to
ask
questions
and
we'll
answer
the
best
we
can.
C
A
Sure,
and
thanks
so
much
for
taking
my
question
and
I,
really
I
love
the
work
that
you're
doing
it's
quite
inspiring
and
I
love
to
see
that
government
on
board
with
doing
this
kind
of
work.
My
question
is
about
how
to
extend
this
stuff
that
you're
doing
to
other
parts
of
the
carbon
accounting
cycle.
E
Oh
I
see
what
you
mean
like
supply
chain
Dynamics
around
actually.
Actually,
I
should
ask
some
clarifying
questions
here.
Are
you
talking
about
the
incentives
for
certain
actors
within
a
supply
chain
to
disclose
information,
or
are
you
talking
about
the
actual
value
of
the
data
itself?
In
terms
of
I
mean
I
I
am
aware
of
some
digital
markets
that
are
that,
where
the
the
environmental
attributes
of
a
project
a
product
are,
they
have
a
value
that
it's
bought
and
sold.
E
A
E
No,
it
does,
and
so
you,
you
kind
of
hit
on
something
that
we
we
have
kind
of
stayed
away
from
supply
chain
type.
You
know
focusing
on
the
product
level,
because
there
are
because
of
what
you're,
you're,
alluding
to
I,
think,
which
is
that
there's
sort
of
disincentives
for
certain
actors
within
Supply
chains
to
disclose
information
and
that
that
I'm
not
like
something
that
we've
learned
from
this
project,
is
that
the
the
technology
doesn't
necessarily
solve
all
problem
existing
problems.
E
So
we
have
on
purpose,
stayed
at
the
organizational
level
and
focus
more
on
sort
of
organizational
identity.
If
you,
you
know,
in
a
sense
like
the
ghd
profile
of
of
a
mine
site
on
an
annual
basis,
as
opposed
to
the
ghd
profile
of
a
product.
That's
you
know
a
unit
of
a
word,
that's
being
mined
from
that
that
mind
and
being
passed
along
the
supply
chain.
E
A
Yeah
and
that
that
makes
a
lot
of
sense,
I
think
it's
also
as
the
as
you
are
able
to
move
the
government
from
the
equation
and
create
an
ecosystem
that
kind
of
runs
itself.
I,
wonder
what
other
stakeholders
are
going
to
come
in
to
help
totally
manage
that
that
incentive
alignment,
but
all
that
other
people
have
answered
questions.
Thank.
C
Question
yeah
I'll
take
a
crack
at
this
one,
so
the
standardization
of
a
credential
schema
really
points
to
governance
in
my
opinion,
and
that
is
sort
of
the
mechanism
for
how
it
is
documented
and
presented
to
the
world
to
say:
hey
this:
this
is
a
credential.
This
is
the
format
for
it.
These
are
the
attributes,
and
these
are
the
rules.
C
C
Well,
what's
that
so,
then
you
need
to
kind
of
point
over
to
an
existing
standard,
the
naics
just
for
for
somebody
to
understand
what
the
actual
data
values
are,
so
that
kind
of
information
is
best
written
into
a
governance
framework
not
necessarily
directly
into
the
credential.
So
it's
information,
that's
always
passed
around
again
for
a
technology
efficiency
perspective,
and
then
you
know
when
we
look
at
somebody
like
the
verifier
who's
consuming
that
data,
they
don't
necessarily
need
all
that.
You
know
kind
of
metadata
and
extra
information.
C
They
just
need
the
code
for
that
credential.
They
already
know
how
to
parse
that.
So
the
standardization
process
is
a
bit
more
challenging
and
we're
working
honestly
with
the
number
of
Standards
bodies
to
actually
to
already
create
these
kinds
of
standards.
They
already
exist
in
often
different
formats.
What
we
need
to
do
is
work
with
them
to
say,
hey.
This
is
the
digital
version
of
that
and
have
them
sort
of
create.
You
know,
create
a
document
or
publish
that
kind
of
a
standard.
C
There
are
other
mechanisms,
for
you
know
actually
having
the
something
searchable.
You
know
we're
using
hyper
Ledger
Indie
as
our
our
base
ledger.
So
you
know
looking
at
something
like
a
browser
to
look
on
that
ledger
to
see.
Oh,
is
there
something
named
an
emissions
report
or
something
like
that
right?
Is
there
a
way
to
search
for
that,
and
then
maybe
it
could
point
back
to
some
standards
bodies
website
which
actually
has
all
the
governance
info
information
on
it.
So
we
are
we're
looking
at
that,
but
the
actual
government
of
BC.
C
We
are
in
control
of
some
standards,
but
not
all
right,
so
the
actual
credential
that
we're
looking
at
here
is
something
that
is
for
the
most
part
written
into
legislation,
but
it's
not
written
into
legislation
as
a
verifiable
credential
with
very
specific
pieces
right.
We
can
point
to
the
regulation
to
say
these
are
all
the
things
that
need
to
be
in
that
report,
but
we
can't
put
that
obviously
directly
into
regulation.
That
needs
to
be
something
presented
on
a
website,
so
I
hope
that
answers
your
question.
B
Elizabeth
I
see
that
you
have
a
question:
I,
don't
fully
understand
it
if
you
can
re-frame
it
and
post
it
in
the
comments
section,
I'll
I'll
try
to
get
to
it.
I
I
have
a
quick
question:
I'm
curious
about
the
open,
Earth
Foundation,
the
dashboard
that
you
mentioned,
that
they
are
using
the
data
provided
for
voluntary
and
Regulatory
markets.
B
C
Okay,
so
the
first
thing
to
recognize
is
that
the
ecosystem
that
we're
working
through,
let
me
go
back
to
this
picture.
The
ecosystem
that
we're
working
through
is
an
open
one
right.
It's
not
a
closed
sort
of.
You
know,
blockchain.
Sorry,
that's
that's
the
wrong
term
to
use,
but
it's
not
a
closed
ecosystem
where
we
hold
the
keys
and
we
let
people
in
this
is
an
open
environment.
C
This
is
an
open
exchange,
and
so
the
way
to
to
look
at
it
is
it's
all
peer-to-peer
transactions
that
are
writing
and
rooted
on
a
distributed
ledger.
So
pricewater
Coast
Coopers
when
they're
issuing
their
credential
and
it
goes
to
Copper
Mountain.
That
is
that
is
it
that
is
a
peer-to-peer
transaction.
They
are
sending
them
a
credential
and
that's
it
now.
Copper
Mountain
has
a
thing:
they
have
a
credential
that
they
can
use
and
they
can
do
whatever
they
want
with
it,
and
PWC
won't
even
find
out
about
it.
C
There
is
proof
in
that
credential
that
it
was
issued
by
Price
writer
host
Coopers,
but
pricewaterhousecoopers
doesn't
like
get
a
report
and
it's
not
sort
of
you
know
something
written
to
the
chain
that
everybody
can
read
so
Copper
Mountain
now
has
this
credential
or
set
of
credentials
and
when
they
do
their
peer-to-peer
transactions.
They're
doing
one
peer-to-peer
transaction
with
the
government
to
present
a
some
subset
of
their
information
that
they
hold
in
their
wallet
they're
doing
a
different
peer-to-peer
transaction
completely
with
open
Earth
again.
C
Nobody
else
in
the
ecosystem
knows
about
that.
Peer-To-Peer
transaction
Copper
Mountain
is
just
sending
a
subset
of
information
to
open
Earth
and,
let's
say
it's
their
2021
carbon
emissions
data
they're,
sending
that
subset
to
open
Earth
and
the
open
climate
portal,
which
is
the
tool
that
open
Earth
uses,
is
going
to
present
that
information
in
a
website.
C
They
have
a
demo,
in
instance,
right
now,
where
you
can
kind
of
play
around
and
look
at
some
of
the
information
there.
But
we
can.
What
you
would
be
able
to
see
is
copper,
Mountain's
report,
a
voluntary
report
for
their
carbon
emissions,
and
you
can
see
in
that.
In
that
web
interface,
the
actual
verifiable
check
like
it's-
it's
the
presentation,
request,
information
to
say
who
issued
this,
who
verified
that
this
information
was
valid
or
correct.
C
So
that's
you
know,
sort
of
a
very,
very
basic
way.
It's
again,
as
Nancy
mentioned
organizational
identity,
type
of
information
to
say
this
is
something
about
Copper
Mountain
and
their
carbon
emissions
doesn't
talk
about
the
copper
exactly,
but
it
talks
about
the
organization
and
the
carbon
emissions
right
to
actually
start
linking.
C
B
Does
that
help?
Yes,
it
does.
Thank
you
very
much
moving
down
as
quickly
as
possible,
you
might
have
to
say:
can
you
help
explain
who
will
be
the
owner
of
the
data
in
the
system
considered
considering
third
parties
through
API
I?
Think
you
just
kind
of
spoke
to
that
I
was
wondering
how
you
I
was
wondering
how
you
to
worth
an
account
for
the
climate
data
coming
into
the
system.
What
standards
and
checks
do
you
use
to
ensure
that
that
is
accurate.
C
So
price
Runner
host,
Coopers
they're
already
doing
this
process,
they're
they're
doing
a
verification.
They
follow
a
lot
of
Standards
I,
don't
have
them
all
in
the
top
of
my
head
to
validate
that
the
data
is
is
accurate,
but
they
are
the
issuer
they're,
the
ones
sort
of,
in
a
sense
on
the
hook
to
say
that
the
data
is
accurate
and
once
it's
that
data
is
written
into
that
credential,
it
cannot
be
changed.
C
B
A
B
C
You
could
have
others
in
the
ecosystem
who
are
actually
doing
a
presentation
request.
That's
the
exchange
in
Aries
to
say:
hey,
I
want
to
go
and
connect
with
this
entity
and
ask
them
for
a
subset
of
information.
So
you
could
have
an
investor.
Let's
say
in
this
space
as
well,
to
ask
Copper
Mountain
at
Whatever
frequency
to
say:
hey.
B
E
Sure,
yes,
we've
definitely
thought
about.
It.
I
think
the
sky's
the
limit
with
these
credentials.
It's
really
a
matter
of
the
reason
we
focused
on
the
one
we
focused
on
is
because
we
wanted
to
map
to
an
existing
process
going
forward.
If
there's
demand
for
from
anyone
in
the
ecosystem
to
want
to
do
a
gri,
credential
or
tcfd,
really
any
other
ESG
framework,
it's
it
is
totally
possible
to
do
it.
B
You
did
thank
you,
I
think
so.
I've
got
one
final
question
is
I'm
just
going
to
read
exactly
how
it
was
written,
it
says
means
the
beefy
gov
trust
the
credential
without
verifying
the
issue
or
credential.
If
the
BC
gov
checks
the
issue
or
how
are
you
sure
that
PWC
assigned
sign
signed
the
credential
and
not
somebody
else.
C
Right,
so
that
is
the
nature
of
the
technology
that
we're
using
with
these
verifiable
credentials.
So
the
when
PWC
issues
the
credential
to
Copper
Mountain,
it's
cryptographically,
signed
essentially
and-
and
you
know
bound
to
the
attributes
so
that
when
the
VC
government
receives
that
information,
they
can
check
that
credential
that
it's
cryptographically
valid.
They
can
also
check
using
the
distributed
Ledger
that
it's
not
been
revoked.
A
C
You
know,
there's
a
list
of
you
know,
assessors
or
in
our
case,
for
the
BC
government
in
regulation.
It
says
that
the
issuing
company
for
verification
statement
needs
to
have
a
certain
accreditation
and
I
can't
remember
what
it
is
for
this
space
I
really
need
to
write
it
down
and
put
it
on
a
Post-It
note
on
my
screen,
because
that
question
comes
up,
but
yes,
that
that's
that's
a
sort
of
an
existing
list.
C
A
A
C
Yeah,
there's
a
few
different
ways
to
trust
the
issuer
and
we're
exploring
some
of
those.
Some
of
them
could
be.
You
know,
kind
of
a
link
into
the
credential
itself,
I
I,
you
know
the
trust
registry
space
and
the
Machine
readable
governance
is
sort
of
that.
Other
aspect
is
still
a
space
that
is
really
expanding.
C
C
At
the
end
of
the
day,
you
don't
actually
need
to
use
the
trust
registry,
but
it
is
an
important
piece
you
can
still.
You
know
know
that
the
data
has
not
been
tampered
with.
You
know,
British
Columbia
might
be
using
it
different
trust
registry
than
even
open
Earth.
That's
another
thing
to
kind
of
point
out
it
it.
You
know
it's
for
the
verifier
to
have
their
list
their
checking
against
it's.
It's
not
necessarily
going
to
be
the
same
set.
B
Well,
that's
fantastic
I
can't
believe
we
got
through
all
the
questions.
We
had
a
really
good
discussion,
the
presentation,
my
my
my
intros,
but
that's
fantastic,
Kyle
Nancy.
This
has
been
a
great
presentation
as
usual.
It's
really
exciting,
to
see
you
guys,
leading
the
charge
and
and
really
I
think
kind
of
pushing
the
boundaries
and
and
offering
a
real
use
case
for
this
big
fighting.
It's
inspiring
for
all
of
us,
and-
and
thank
you
thank
you
for
joining
us
once
again.
