Following COP29, how can countries catalyse investment towards climate action plans? 

In November 2024, COP29 took place in Baku, Azerbaijan. 

A focus this year has been to align climate finance contributions to global needs, as well as looking to ramp up the role of the private sector and unblock barriers to investment.

On Tuesday 12th November, Prime Minister, Sir Kier Starmer MP addressed the Summit outlining the critical role the UK must play in climate finance, as well as introducing the new target of reducing UK carbon emissions by at least 81% by 2035 compared to 1990 levels. 


“This is a huge opportunity for investment, for UK business, for British workers – if we act now.”

– Prime Minister, Sir Kier Starmer MP, COP29  

The Prime Minister also used the Summit to announce the launch of the new CIF Capital Market Mechanism, which could mobilise up to $75 billion in climate capital for developing countries over the next decade.  

According to the Prime Minister, its listing on the London Stock Exchange cements London as a green finance capital and showcases the UK at the forefront of global climate investment. 

At 3Ci, we hope to see positive outcomes from the discussions around successfully mobilising private finance towards net zero ambitions. However, we understand the challenges that face this from our own experience in the UK where our partnership includes representation from 90% of local government. 


Below, we outline some of the challenges the UK faces when it comes to successfully investing in net zero, along with solutions 3Ci’s public-private coalition has been working on – which represent a major opportunity for the UK to establish a global lead on climate finance. 


1. Deploying climate finance 

Private investors are increasingly attracted to climate finance opportunities. However, they struggle to discover well-developed projects into which they can deploy their investment.

2. Upskilling local authorities 

Local Authorities often lack the skills and capacity to plan and develop projects that demonstrate a return on investment and are at the scale needed to be attractive to private investors. Often project development takes too long to become investable, discouraging private sector involvement. 

3. Upfront investment

 Project development and replicating successful projects like Bristol City Leap requires significant upfront investment, which UK cities no longer have access to through European sources. Private investors are also not a like-for-like replacement for grant funding. 

4. Government and procurement 

Currently, there’s a lack of a clear framework for local governments to play an effective role in supporting national government objectives, which may lead private investors to lack confidence in their potential. Procurement regulations can also impede the private sector in helping local authorities design projects, further reducing their capacity for project development. 


These challenges are well known to 3Ci and are topics that we are actively focused on solving with our work. 

Our programmes address key climate finance challenges in the UK by fostering collaboration among local authorities, national government, and the private sector: 


  1. Net Zero Neighbourhoods – A programme of UK-wide demonstrators which test and showcase the delivery of an integrated local net zero investment model. 
  1. National Net Zero Project Pipeline – A national register of local and regionally led investible projects, articulated to a common and combinable format, to deliver net zero outcomes.  
  1. Technical Assistance for Investible Places – A development fund that invests in the necessary capacity and skills to bring projects forward for investment.  
  1. Regional Investor Events – Convening cities and local governments with investors to showcase opportunities, building mutual understanding and confidence.  
  1. Local Innovation Models – A national platform to share innovations rapidly in an easily accessible and standardised format.   

Post COP, we will continue to work with the private sector and UK government to unblock barriers to investment and support delivery on the UK’s COP commitments.

3Ci’s reflections on the Autumn Budget – and what it could mean for the UK’s Net Zero future.

On Wednesday 30th October, the Chancellor of the Exchequer Rachel Reeves MP announced the new Budget.  

We delved into some of the Budget announcements that are relevant to supporting our mission here at 3Ci: to enable private investment into local Net Zero across the UK, creating jobs and growth to support a Just Transition to a low carbon future.  


Broadly, these fit into these “three Cs”: 

  • Clean Energy – from the Warm Homes Plan to Great British Energy (GB Energy), the latest updates are crucial in underpinning the UK’s drive towards greater energy security. 
  • Connectivity – increasing connectivity is paramount to achieving national, but also local, growth. The Budget lays out several transport commitments to accelerate this in the UK. 
  • Carbon Capture – in addition to last year’s carbon capture plans from the UK government, Reeves announced further funding for 11 new green hydrogen projects. 

Below, we examine how each of these subjects have featured in the Budget Announcement, as well as our perspective on their significance to the UK’s broader vision for Net Zero. 


Clean Energy

The budget provided £1billion toward the Warm Homes Plan next financial year and a further £3.4billion across the following two years. 3Ci’s already stated position is that the UK could retrofit three times the number of homes per £ of public investment by spending a small amount up-front on demonstrating innovative financing models like Net Zero Neighbourhoods (NZNs), potentially leveraging £billions of private investment.

NZNs are a ‘no-cost to owner or tenant’ model that turn energy savings into an annuity, meaning private – and other – investment can be attracted to pay for the retrofit works. They are also neighbourhood-wide and focused on local renewal and job creation, not just building works. You can find out more in The Case for a National Net Zero Neighbourhoods Programme.

In reality, several NZNs are about to get off the starting blocks, and the same principle has been used in Local Net Zero Accelerators, so a demonstrator programme is not only cost effective, it is highly achievable.

Separately, 3Ci has welcomed the inauguration of Great British Energy (GB Energy), anticipating further investment into creating more energy security in the UK, including the establishment of the Local Power Plan focused on co-investment in “shovel ready” local authority led projects that provide community benefit. 3Ci also recognises the investment that will be undertaken with the National Wealth Fund. Working with its predecessor, UKIB, 3Ci’s National Net Zero Project Pipeline with over 1,200 projects of £40-60bn of investment provides significant opportunities for collaboration alongside both GBE and the NWF.

GB Energy’s remit will include accelerating existing projects delivering green energy such as wind farms, as well as developing and co-investing in new energy sources that provide community benefit, driven through the new Local Power Plans. The Chancellor has announced funding in the latest Budget to help achieve this, as well as a commitment to establishing its headquarters in Aberdeen.

The above measures rely on having the right levels of capacity in local authorities – and elsewhere in the system – to bring projects up to investment grade, and whilst there is not a separate commitment to this within the Budget, 3Ci will be working with partners to understand how this can best be achieved, as a key to realising private investment and Net Zero ambitions. Underlying these points is the overall resource available to local authorities, which remains under significant pressure.

Connectivity

Increasing connectivity, particularly in the UK, is paramount to achieving national, but also local growth. Public transport infrastructure needs to be able to support our growing population as well as meeting net zero targets, and many infrastructure projects also rely on private investment. They can be highly attractive to patient investors like pension and insurance companies, if developed in the right way.

The Autumn Budget included:

  • The delivery of the Trans-Pennine upgrade to connect York, Leeds, Huddersfield and Manchester, “delivering fully electric local and regional services between Manchester and Stalybridge by the end of this year”.
  • The Budget commits to an east-west rail to drive growth between Oxford, Milton Keynes and Cambridge.
  • There will be more railway schemes to improve journeys across the country.
  • There will be funding for HS2 to extend the line to London Euston.
  • £1.3bn funding has been announced to improve connectivity within city regions.

Several projects within 3Ci’s Net Zero Pipeline also include transport and connectivity, and we will be seeking ways to bring them forward in a manner that attracts private investment.



Carbon Capture

At the end of last year, the UK Government set out plans for a new competitive UK carbon capture, usage and storage market by 2035 – delivering new jobs and supporting net zero. These plans were supported by a £20m investment fund.

In an exciting update in the latest Budget, further funding was announced for a new, multi-year investment into carbon capture and storage.

Funding will be provided to 11 new green hydrogen projects across England, Scotland and Wales. These will be among the first commercial-scale projects anywhere in the world. 3Ci sees this as a significant opportunity to attract investment into localities across the UK that could target multiple assets alongside these storage and capture facilities, increasing growth and boosting jobs.
