All OECD countries have a national adaptation policy...
which includes a
section on how to
track and evaluate
progress
Half of OECD
countries developed

Growing number of
mandates in climate laws

Working Party on
Be specific (sector, geographic
area, type of actions)
“Reduce vulnerability and improve the
adaptive capacity of ecologic, social and
economic systems towards the unavoidable
impacts of climate change”
Objectives are often generic and not
specific enough to be measurable
DEVELOP ADAPTATION POLICY RESPONSES
Translating climate risks into objectives
Reflect key climate risks
Set baseline and timeframe
for achieving the objective
…identified in 2020 by 2030 as far as possible.”

flooding…

Establish a pyramid
showing how actions
aim to contribute to
overall objectives
High-
level objectives
Targets
Actions Objectives Halt the decline in species abundance
by 2030 by reducing risks to terrestrial
species and habitat
Restoring 75% of terrestrial and freshwater sites to
favourable condition by 2042
Become a climate-
resilient country
Reducing household and non-household
water consumption to improve water
efficiency to prevent over-abstraction
impacts on freshwater habitats and
species
DEVELOP ADAPTATION POLICY RESPONSES
Translating climate risks into objectives

MEASURING POLICY IMPLEMENTATION
11
Working Party on
WHAT DO COUNTRIES MEASURE IN PRACTICE?
Resources engaged
“Annual expenditure for flood
defences”
➢ Ambition to measure the
resources (e.g. budgets and
staff) engaged for adaptation
actions
➢ Difficult due to lack of resources
tagging
Direct results
“Physical measures, regulations or
plans implemented”
➢ Common practice to measure
direct results
➢ Increasing number of tracking
tools (UK & France track 253 and
240 Nap actions, respectively)

12. Working Party on Climate Change (WPCC)
MEASURING IMPACT
12
Working Party on
Impacts
“Annual damages from
flooding, agricultural losses
from drought, number of heat-
related deaths”
To a lesser extent do countries
measure the impacts that result
from implemented actions
Climate impact Policy impact
Challenge of attributing
actions to reduction in climate
risks and impacts

Value of establishing sectoral and local indicators and defining
whether these should look at process or outcome.
Relevance for national vs for international work
Importance of promoting collaboration among data providers
and users.
Opportunity to look at agriculture in collaborative work with TAD
