Global trajectories for reducing carbon emissions depend on the local adoption of alternatives to conventional energy sources, technologies, and urban development. Yet, decisions on which type of capital investments to make, made by local governments as part of the normal budget cycle, typically do not incorporate climate considerations. Furthermore, current academic and professional literature specific to climate change draws attention to decision-making tools that would require access to technical expertise, data, and financial support that may not be practical for cities in low- and middle-income countries. Arguably, the methodologies most able to effect this transformation will be those that are convenient and affordable to administer, and that offer straight-forward low carbon alternatives to traditional forms of infrastructure investment. Current methodologies for capital investment planning that do not take climate change into consideration can result in prioritization of investments that diverge from a low carbon path and a potential missed opportunity to reap financial benefits from efficiency gains. This paper concludes that relatively minor alterations to common procedures can reveal the trade-offs and local benefits of low carbon alternatives in the capital investment planning process. This paper was written as an input to the preparation of the Climate-Informed Capital Investment Planning Guidebook, a how-to guide for local government staff, which will be published in 2015.

Much of the world’s built environment is found in urban areas, and cities are thought to be responsible for up to 70 percent of global greenhouse gas (GHG) emissions, and up to 80 percent of primary energy demand. Most of the energy consumed in the world fuels urban industry, powers urban homes and offices, and moves people within and between cities. This paper is about climate change mitigation in cities, and will primarily look at how local authorities can provide a higher quality of life for their citizens while at the same time achieving higher resource efficiency. It will also look at how climate change mitigation measures could help boost local employment and drive economic growth. The focus will be on buildings (residential, commercial, and office), public services infrastructure (water, sewage, solid waste management, and public lighting), and urban form. Other topics of interest in this respect, such as transport and industrial production will be discussed tangentially in relation to the other topics (e.g. urban form influences and is influenced by transport patterns and strategies).

Nearly half the world's population and about 81 percent of Sub-Saharan African (SSA) households rely on wood-based biomass energy (fuel wood and charcoal) for cooking. This degree of reliance is far greater than in any other region. While the use of biomass fuels in China, India and much of the developing world has peaked or will do so in the near future, SSA's consumption will either remain at very high levels or even grow over the next few decades. Population growth, coupled with strong urbanization dynamics and relative price changes of alternative fuels, offset the important achievements made over the past decade by significant investments in energy access, rural and urban electrification, off-grid energy developments, and the promotion of alternative energy sources. With increasing economic development, the demand for energy is increasing as well and consumers depend on a broader portfolio of energy sources to satisfy growing energy needs. While electricity and other energy sources are needed to satisfy additional energy needs emerging with economic development, a vast majority of Sub-Saharan African consumers continue to use wood based biomass energy for cooking. Especially electricity is not regarded a suitable alternative for cooking given equipment and use costs. Biomass burning in cook stoves also emits black carbon (BC) as part of visible smoke, which is particulate matter that results from incomplete combustion. Climate science now views BC as the second or third largest warming agent after carbon dioxide, alongside methane. In the case of biomass cooking, the warming effects of BC and the cooling effects of organic carbon that is also emitted during the burning appear to be closely balanced. Given the present uncertainty about the net impact, additional research is currently underway. Black carbon has also an impact at the regional level: it accelerates melting of ice and snow, and contributes to regional pollution which can alter climatic conditions and precipitation patterns over a wide area. This paper advocates that any policy reform should entail a combination of clear rules, transparent enforcement, strong incentives and awareness-creation/capacity development. Key stakeholders and the general public need guidance by way of information campaigns, training, and demonstration projects to ensure that awareness-deficits or false perceptions do not curtail policy implementation. The bureaucratic and administrative barriers e.g. overcomplicated forest management planning requirements, complex fiscal systems and land tenure procedures may inhibit development and thus warrant critical reflection. The regulatory framework needs to integrate externalities in order to promote adequate pricing of charcoal, and thus enhance regional economies.
