Inter-municipal Cooperation is the key to better environments in our cities.

Victor Osei Kwadwo

The 2021 United Nations Climate Change Conference (COP26) aims at “Uniting the World to Tackle Climate Change”. While the technical aspects to addressing climate change is more evident in the goals of COP 26, it is time attention is equally paid to the governance of climate change at the metropolitan scale made up of our major cities.

Due to rapid urbanization, the world is increasingly becoming metropolitan. Cities have expanded outwards and have become more interdependent with their immediate peripheries. Cities occupy only approximately 2% of the world’s total land yet host 54.5% of the world’s population. Cities are responsible for 70% of the world’s GDP, over 60% of global energy consumption, 70% of global greenhouse gas emissions, and 70% of global waste.

As cities agglomerate, the footprint and interdependence within and between cities blur existing administrative boundaries to the extent that development issues in one local government jurisdiction have spillover effects on neighbouring jurisdictions. These spillover effects have led to a call for cooperation on functional grounds, making metropolitan areas a salient scale for public policy interventions. Metropolitan areas such as Cape Town, London, Mexico City, São Paulo and Tokyo are mainly characterised by densely inhabited functional urban areas and their surrounding interconnected lower-density areas.

In the management of metropolitan areas, for instance, many cities in the USA, Greater London, Brussels, Dar es Salaam and Greater Accra, the joint provision of metropolitan-wide services or jointly addressing a cross-boundary problem is an explicit choice of local governments that make up the metropolitan area. This voluntary nature of cooperation poses a collective action dilemma when local governments have to address problems jointly.

The dilemma arises from the externalities of environmental outcomes that drive low incentives for cooperation and a high risk of free-riding. To find joint solutions to cross-boundary problems in metropolitan areas, inter-municipal cooperation (IMC) is identified as critical for better economic and environmental outcomes in service delivery. There is empirical evidence that inter-municipal cooperation saves costs but does it also improve environmental outcomes?

Governments tend to be reluctant to cooperate when environmental outcomes are at stake, and this is partly due to the limited evidence on the impact of cooperation on environmental outcomes. It is therefore important to provide an evidential basis on which local governments can justify and initiate cooperation arrangements to address environmental concerns jointly.

In a study I co-authored with Tatiana Skripka, we provide this evidence using data covering 229 metropolitan areas in 16 OECD countries. The study tests the impact of cooperation in transportation on CO2 transport emissions. We did this by estimating a three-level mixed-effects model that takes into account both national and metropolitan-specific characteristics.

The results demonstrate that if local governments cooperate, better environmental outcomes can be achieved. Metropolitan areas that worked together on transportation issues were able to reduce CO2 transport emissions.

The findings give an indication of what needs to be done to effectively fight the environmental challenge. More significantly, beyond normative predictions, the findings provide a basis for local governments to justify and pursue local to local partnerships to address environmental issues.

What we measured

We used “working together on transportation” as a measure of cooperation and “CO2 transport emissions” for environmental outcomes to estimate the impact of cooperation on CO2 transport emissions reported in 2000, 2005 and 2008 for 229 metropolitan areas in 16 OECD countries.

We accounted for factors such as the year of observation, economic status, socio-cultural, geographical, technological and governance measures such as mitigation policies, enforcement, and metropolitan structure. The factors covered both the national and metropolitan area-specific characteristics: socio-cultural conditions, level of technology, geography, and metropolitan governance structure. We used data from the OECD metropolitan governance database, the OECD Metropolitan Governance Survey, the World Bank, among others.

Key findings

We found that metropolitan governance structures, whether fragmented or consolidated, are equally inefficient in delivering reduction in CO2 transport emissions. The finding contrasts with an increasing trend of scholars advocating for fragmented metropolitan structures that favour voluntary cooperation, compared to consolidated structures that address collective action problem through coercion.

We also found that countries with a higher GDP were more efficient in reducing CO2 transport emissions. In contrast, metropolitan areas with higher GDP recorded increases in CO2 transport emissions. While national funding can dictate climate-related interventions and standards, metropolitan wealth is more flexible in taking on such obligations. As metropolitan areas are mainly production centres, investments in environmentally-friendly interventions may be more easily sacrificed at the metropolitan level for economic gains.

We further found that CO2 transport emissions increase despite the mere presence of environmental mitigation policies. This is consistent with empirical observations. For example, while the Paris Agreement has 196 Parties adopting to limit global warming to less than 2 degrees Celsius, emissions have continued to rise globally by 1.4 per cent per year on average since 2010. Environmental policy effectiveness lies in the ability of the cooperating parties to ensure widespread policy implementation and enforcement.

The crucial factor explaining the reduction of CO2 transport emissions in metropolitan areas is inter-municipal cooperation that facilitates coherence and widespread enforcement of mitigation policies. The impact of cooperation on CO2 transport emissions is magnified in metropolitan areas within countries that have stringent environmental mitigation policies.

Next steps

Inter-municipal cooperation (IMC) is critical in the governance of metropolitan areas if better environmental outcomes are to be achieved in our cities. Cooperation ensure policy uniformity, facilitates the possibility of widespread enforcement and reduces incentives for free-riding irrespective of governance structure. It is recommended that scholars and policymakers emphasise how to incentivise effective cooperation regardless of the metropolitan governance structure. Also, efforts must be geared toward uniform mitigation policies and their subsequent enforcement across local jurisdictions in metropolitan areas.

The Transformative Politics of the European Green Deal

by Jon Bloomfield

COVID 19 has highlighted our fragile relationship to the planet. But it represents a minor challenge compared to the permanent havoc that runaway climate change threatens. Politicians and governments – some at least – are beginning to recognise the scale of the danger. In this article we assess the evolution of policy thinking on how to make climate transitions happen; the potential of the European Green Deal; and how progressives need to shape it and any UK counterpart to meet the challenges of modern society.

The European Green Deal initiative launched in December 2019 arose from a broad coalition spanning the political spectrum. Yet its central thrust of active government offers the prospect of reviving a battered social democracy. Green Deal politics failed to cut through after the 2008 financial crisis. Post COVID19 offers a second chance. There is a greater consensus around the need for active government and public investment to help the economy, underpinned by a recognition of the importance of equity to address issues of inequality and disadvantaged regions. This is moving politics onto traditional social democratic terrain, even when it is German Christian Democracy and French centrism that is taking it there. The politics of climate transition needs to be developed on a broad, cross-party basis but it offers major opportunities for social democracy, if it is able to embrace a pluralist and environmentalist approach suited to the challenges of the 21st century.

So what can a ‘social democracy re-born’ offer?  The starting point has to be a recognition that the climate crisis requires a re-making of everyday politics, on the Left as well as the Right. The 19th and 20th century model of high-carbon, fossil fuel intensive economies where the core task is for ‘man to conquer nature’ has run its course. To safeguard our common future a new low carbon model of sustainable development has to become the ‘common sense ‘of the age. That’s what the policy specialists and architects of the European and the US Green Deal have formulated. Politicians and parties across the spectrum are trying to catch up. The anticipated post-Covid, green recovery programmes in the run-up to COP 26 will show which political forces are best able to translate this thinking into everyday politics and to make low or zero-carbon initiatives the golden thread that runs through their policy proposals.

The elements of active government, collective goods, and social inclusion chime with the social democratic tradition yet it needs to overcome the contradictory baggage of utopianism on the one hand, and industrialism on the other. There are four areas in particular where a shift in social democratic thinking is needed.

Firstly, it needs to adopt a 21st Century modernity. The Green Industrial Revolution should no longer be the metaphor of choice. It speaks to a technocratic, top-down model of traditional Keynesianism.  This conjures images from the past while constricting the imagination of the present and future. The potential of a mix of social innovation and digital revolution to transform ‘soft’ infrastructure needs to be at the heart of green deal proposals.  Currently they play second fiddle to ‘hard’ infrastructure investment. Yet new tech opens new vistas.

Secondly, the potential widespread attractiveness of changes in lifestyle through sustainability transitions should be highlighted.

Thirdly, pluralism has to be at the heart of any effective, green deal movement. Successful sustainability transitions rely on a wide alliance of social actors with a shared vision.

Fourthly, the 21st century world is interdependent. We live in a world where the local and regional overlap and are intertwined with the national, Continental and global.   The interconnections are all the stronger when it comes to tackling a great societal challenge like climate change which is why centralised, top-down methods are not the answer. Rather than reheat an old, mission-driven approach, sustainability transitions need a challenge-led approach where national government specifies the broad direction but acknowledges that experimentation around a diversity of solutions must be nurtured with groups of stakeholders at local and city level.  The classic big national projects find this very difficult. They favour national ‘rollout’ with budgets held in Whitehall and local authorities administering central government decisions. The debacle on the UK’s COVID test and trace programme has served to highlight the limitations of this model of politics. Central to the green deal should be transition programmes which set clear sustainability targets but where budgets are devolved to enable localities to design initiatives appropriate to their needs in partnership with local stakeholders.

Our article indicates the openings here for a pluralist, ecological Left. The run-up to the next global climate conference –COP26- will be a vital period which will show whether parties and governments across the world are prepared to meet the climate change challenge.
