Local climate information from CAPE
Climate change is a global challenge, but reaching the UK's carbon emissions goals requires local action.
Local councils, either through their services, or through their influence on residents and local businesses, have influence over one-third of UK emissions.
mySociety and Climate Emergency UK have created CAPE - to make councils' commitments, plans, and progress on climate action transparent and accessible to all.
We are working to improve the quality of information that is available about local climate action, and about the levels of public support for climate action.
By promoting information sharing and constructive scrutiny, we aim to drive more effective and coordinated action to reduce emissions.
For Portsmouth City Council we have collected the following information: powers & responsibilities, your representatives, declarations & pledges, climate documents, council actions scorecard, emissions data, local polling and related councils.
Powers & Responsibilities
Portsmouth City Council is a Unitary Authority.
This means it does not split different kinds of responsibilites with a county council.
This kind of council has powers and responsibilities for:
Council buildings and staff
Climate actions might include:
- making council offices more energy efficient
- incentivising ‘Active Travel’ or public transport use among employees
- providing carbon literacy training for employees
Environmental health
Climate actions might include:
- reducing industrial emissions through air quality enforcement
- bringing up insulation and energy efficiency standards through enforcement of the Housing Health and Safety Rating System (HHSRS) and Decent Homes Standard 2000, for cold and damp conditions in private rental and social housing
See more in the Climate Emergency UK checklist.
Passenger transport
Climate actions might include:
- encouraging bus and private hire operators to use low-emission vehicles, through licensing requirements or Clean Air Zones
- incentivising bus use by improving routes, timetables, and ticket prices through ‘Enhanced Partnerships’ with operators
- proposing to central government the development of light rail / tram networks that integrate, rather than compete, with other modes of transport in the area
See more in the Climate Emergency UK checklist.
Planning and building control
Climate actions might include:
- imposing reasonable requirements that new developments comply with energy efficiency standards and get a proportion of their energy from local, renewable sources (Planning and Energy Act, 2008)
- incorporating additional energy performance standards into their Local Plan, for new works that require planning permission
- using Area Action Plans to guide development proposals towards lower carbon emissions or more cycling and walking routes, for example
- enforcing legislation that requires private rental properties to be of Energy Efficiency Rating E or above (Energy Efficiency Regulations, 2015)
- funding energy efficiency improvements on existing homes, through initiatives such as Green Homes Grants
See more in the Climate Emergency UK checklist.
Schools and libraries
Climate actions might include:
- reducing the carbon footprint of civic buildings through better insulation and renewable energy use
- incentivising ‘Active Travel’ or public transport use among employees
- providing carbon literacy training for employees
- encouraging eco-clubs at schools
- using school land to plant trees and hedgerows, or to grow food
See more in the Climate Emergency UK checklist.
Housing
Climate actions might include:
- setting energy standards above building regulations (Planning and Energy Act, 2008)
- enabling housing associations to improve the energy efficiency of their housing stock through loans
- where councils operate their own social housing, prioritising energy efficiency – for example, by requiring Passivhaus standard for newly built schemes
See more in the Climate Emergency UK checklist.
Spending, procuring, and investing
Climate actions might include:
- embedding carbon impact assessment as part of the council’s budgeting and financial accountability process
- utilising Public Works Loan Board loans or the Business Rates Retention Scheme to invest in emissions-reducing capital projects that otherwise wouldn’t get funded
- specifying low carbon equipment and practices when procuring for relevant services from suppliers
- prioritising positive environmental impacts during procurement, through the Public Services (Social Value) Act 2012
Transport planning
Climate actions might include:
- incentivising ‘Active Travel’ like walking and cycling by creating or widening footways and cycleways
- incentivising Electric Vehicle use by assigning street space to EV charging
- disincentivising the use of fossil fuel cars through congestion charging,low-traffic neighbourhoods, or the reduction of parking space
See more in the Climate Emergency UK checklist.
Waste collection and disposal
Climate actions might include:
- establishing ‘Joint Waste Solutions’ with neighbouring councils, to get more value out of waste, recycling, and street cleaning contracts
- running marketing campaigns to encourage residential recycling, reuse, and waste minimisation
See more in the Climate Emergency UK checklist.

We also run WriteToThem.com, which you can use to find out all your representatives from different layers of local, devolved, and national democracy.
You can also use it to send a message to your councillors, MP, or other representatives.
Declarations & pledges
Climate emergency declaration
Portsmouth City Council declared a climate emergency on March 19, 2019.
Whole area pledge for 2030
“Pledge to achieve net zero carbon emissions in the Portsmouth by 2030, considering, both production and consumption of emissions according to the Standard provided by the Greenhouse Gas (GHG) Protocol.”
A council declaring a climate emergency is an official recognition of the urgent need to address and mitigate the impacts of climate change at a local level. See a list of councils which have declared a climate emergency.
A whole area pledge is a commitment to reduce emissions across the geographic area, including emissions by homes and businesses. See a list of councils which have made a whole area pledge.
A council only pledge is a commitment to reduce emissions that the council is directly responsible for through its buildings, operations, and services. See a list of councils which have made a council-only pledge.

The chart below shows change over time in different kinds of emissions. This chart only shows emissions the local authority has influence over, but other national changes also affect emissions.
The reduction over the last decade mostly reflects decarbonisation of the national electricity grid. This is why the change over time is less interesting than the mix of different emissions types. This reflects different paths required for different council areas to reach carbon zero.
We have used these emissions to put councils into clusters with similar emissions. Portsmouth City Council is in the public sector cluster. See councils with similar emissions profiles, or see all councils in this cluster.
Data from the Department of Business, Energy & Industrial Strategy “subset dataset”, representing carbon dioxide emissions within the scope of influence of local authorities.

Data sources
Much of our data is crowdsourced by an army of volunteers filling in Google spreadsheets. This is then combined with some standard data to enable it to be matched up across sources.
Links to council climate action plans were crowdsourced in this spreadsheet. If you find a plan document that we’ve missed, read our guide on what we consider a climate action plan and how to add one to our spreadsheet.
Council climate emergency declarations and net zero commitments were largely collated by Climate Emergency UK staff.
Local authority CO2 emissions estimates are collated by the Department of Business, Energy & Industrial Strategy.
We make use of data from our Council Climate Plan Scorecards project, which was collected with the support of Mapolitical, who donated their UK Government Political Stakeholder data and Look-up API to help us communicate with local authority officers. Read more on the Council Climate Plan Scorecards site.

Similar councils
We have built on open datasets to provide comparisons between councils that are similar in a number of dimensions. You can read a detailed breakdown of how we calculated these dimensions on our blog, but here’s a high-level summary:
Download our nearest neighbour datasets.
Emissions reduction projects
We are able to display emissions reduction projects reported by Scottish local authorities, thanks to the ‘Climate Change (Duties of Public Bodies; Reporting Requirements) (Scotland) Order 2015’ which requires them to submit reports on their climate actions to the Sustainable Scotland Network website each year.
We automatically collect these reports, extract information about the local authorities’ emissions reduction projects, and display them in a more accessible, interactive format, here.
Sadly local authorities in England, Wales, and Northern Ireland have no corresponding reporting requirement, so data is unavailable for them.
