Should cities wait for a global climate deal?

John Roome's picture

We all know that the quality of the air we breathe has an immense impact on the health of the people and the economies of developing countries. Poor air quality can also threaten the economic competiveness of cities. Increasingly global companies consciously chose to locate in livable cities. We’re already seeing that in Asia.  A 2006 survey by the Hong Kong’s Chambers of Commerce showed that worsening air quality was beginning to affect investment decisions of corporations.

 

I spent two days last week at the Suntec Center in Singapore attending the Better Air Quality conference. This year’s theme was Air Quality in a Changing Climate. The link between the two – improved air quality and reducing climate change is sometimes not so apparent and I am glad the conference was making the link clearer. Climate change impacts all countries but the World Development Report 2010 estimates that some 75-80 percent of the damages caused by a changing climate will be borne by developing countries. If we are to limit global warming to about 2 degrees Celsius above the pre-industrial level, we will all need to invest massively in energy efficiency, renewable energy sources, and more efficient transportation.

 

Combating air pollution is one area where it is possible to capture important co-benefits with respect to climate change. By taking specific measures, we can simultaneously achieve local health and welfare benefits (including related to air quality) while also reducing greenhouse gas (GHG) emissions. While it is important to strive for a global deal on climate change, there are a number of things that cities can do in the interim to simultaneously reduce local environmental impacts and reduce carbon emissions. And by demonstrating on the ground some things that can work in this regard, cities can position themselves to access any global carbon financing that might become available as part of a global deal.

 

As part of its Urban Strategy, which we launched in Singapore a year ago, the World Bank is implementing the Eco2 Cities Program. Through this program, participating cities can develop a baseline diagnosis of their current emission status and suggest measures such as improving technologies, better urban transport, and retrofitting infrastructure and buildings. Linking environmental health, energy efficiency, and livability concerns, cities are now considering how to build sustainability into future planning. Renewed emphasis on public transit, higher density, energy-efficient buildings, and better facilities management can contribute to city development objectives while reducing a city’s greenhouse gas emissions and improving air quality.

 

Broadly, in the energy sector, there are also important co-benefits. A recent study by the World Bank concluded that East Asia can stabilize CO2 emissions by 2025 and at the same time improve the local environment and enhance energy security. But this will require major domestic policy reforms. Fossil-fuel subsidies need to be removed. Environmental externalities need to be internalized into energy prices. Scaling up renewable energy will require financial incentives including concessional finance to reach its potential.

 

There is now a widespread interest in green growth and green financing across the Asia region. At the World Bank – Singapore Infrastructure Financing Summit where I also participated last week, we discussed how to jumpstart the financing of green infrastructure initiatives. The World Bank, together with AusAID, will shortly launch a large piece of analytic work on Green Growth and Green Financing.

 

There was wealth of knowledge and best practices available at both conferences.  I am sure many more cities will be able to learn from each other and also follow some of the Singaporean examples to make their cities more livable while simultaneously reducing their carbon footprint.

The impending COP16 in Mexico is unlikely to see much progress in multilateral agreements on carbon emissions targets. Instead, over the past year individual national efforts have developed to reduce emissions, in particular the debate of carbon taxes and investments into green technologies. The recent mid-term Republican victory in the US will also forestall progress on any agreement. The COP16 will likely see more auxiliary piecemeal agreements. http://erictham.wordpress.com/2010/11/15/from-copenhagen-to-mexico-the-climate-changes/

Let me pickup on the important theme of co-benefits that John Roome has so eloquently alluded to. Indeed it was the over arching message of the BAQ 2010 on air quality that I also participated in. This theme seems to be heard increasingly now and is gathering currency. Perhaps it is fed by the notion that as selfish human beings, we tend to give priority to actions with demonstrated local benefits over those with global benefits. However, if those local actions can have the 'collateral' benefit of global benefits, then it is a win-win. In fact we can even take credit for it! So if reducing local air pollution by switching from coal fired boilers for district heating to gas, reduces local air pollution and brings the added benefit of GHG emissions reduction, it would be an example of a win-win situation. This argument goes down well with developing countries for whom local benefits are a priority and who may not immediately see value in climate actions. Another way to view co-benefits is to turn the above argument on its head and look for local benefits of actions taken primarily for global good. This seems to be quite relevant given that climate funds may be significant in the coming years, perhaps even at the expense of ODA, In either case, it can make for a win-win! The new WBG environment strategy (to be released soon) embraces the co-benefits concept as an important pilar for environmentally sustainable development in the coming decade. However as its background paper notes, there is need for caution in labelling actions as co-benefits, since a some of them can also have significant costs attached to them.
