List of Appendices, Glossary of Terms, Acronyms

Carbon emissions

Inclusive of all greenhouse gas emissions (group of gases that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect) and refers to tCO2e unless stated otherwise.

Climate change

Change in global, national, or regional climate patterns (such as temperature, precipitation and wind).

Climate change adaptation and resilience

Improving the adaptation for, resilience to, and optimisation of benefits from, future climate conditions.

Climate change compatibility

The degree to which a particular action is aligned with the climate change mitigation and adaptation.

Climate change mitigation

Preventing or minimising emissions of whole life carbon emission into the atmosphere.

Compatibility

How well two or more things occur together without causing conflicts or problems.

Ecosystem services

Services provided by an ecosystem such as: provisioning services: food, fresh water, wood, medicinal products, etc.; regulatory and maintenance services: purification of air and water, climate regulation, pollination, carbon sequestration, natural pest control etc.; and cultural services: tourism and recreation, cultural heritage, and educational opportunities and a sense of wellbeing.

Nature-based solutions

The sustainable management and use of natural features and processes to tackle socio-environmental challenges.

Resilience

The capacity of a system to absorb disturbance and still retain its basic function, structure and feedback systems - hence the ability to anticipate, prepare for, and respond to hazardous events, trends or disturbances related to climate.

Sustainable Travel Hierarchy

The National Transport Strategy 2 (NTS2) uses the Sustainable Travel Hierarchy to promote walking, cycling, public transport and bike, car and ride sharing in preference to single occupancy car use.

Traffic carbon emissions assessment period

The period from 2030 to 2045 over which the traffic carbon (greenhouse gas) emissions are assessed.

Vulnerability

The characteristics (determined by social, economic and environmental factors) of the option which increase/decrease the susceptibility of the surrounding environment to the impacts of climate change.

With Policy Scenario

Captures policy ambitions including 20% reduction (from 2019 levels) in car kilometres travelled by 2030, and assumptions to significantly reduce levels of commuting/business journeys to reflect post COVID-19 working behaviours, leading to low levels of motorised traffic demand and emissions.

Without Policy Scenario

No policy ambitions are captured, and less significant reductions to levels of commuting/business journeys, leading to higher levels of motorised traffic demand and emissions.
