Will 2015 be a watershed in the human effort to solve global problems, or just another chapter in the history of collective inaction?
The answer will soon become apparent on construction sites around the world.
The two most ambitious international agreements of 2015 – the UN’s sustainable development goals (SDGs) and the Paris climate accord – amount to a historic decision to build a world that reconciles improving human welfare with the reality of climate change.
The SDGs chart a path for eliminating poverty and securing a better life for all by 2030. The Paris accord seeks to stabilise global carbon emissions by the second half of the century, through a rapid move away from high-carbon energy, transport, housing and land use towards efficient, low carbon, climate-resilient alternatives.
But as nations set out to reflect these commitments in planning and budget processes, they face difficult choices: coal or renewables? Highways or public transport? Suburban sprawl or compact cities?
And the window for making such choices is narrow. Existing and projected carbon emissions show the urgency of implementing the Paris commitments. But infrastructure projects are time-consuming and long-lasting. Power plants, for example, take from five to 15 years to plan and build and can then last for half a century. And 70% of the forecast increase in emissions from developing countries is expected to come from infrastructure that has yet to be built.
This means that infrastructure decisions we make in the next few years could cement our ability to meet the Paris goals – or condemn us to a future in which global temperatures rise well above 2C. In the latter scenario, environmental conditions could be so hostile that development goes into reverse, leading to rising poverty and social conflict.
Unfortunately, infrastructure planning is largely disconnected from climate change agendas for many governments and the current economic downturn threatens to widen this disconnect.
In this context, can elected officials justify using scarce public resource to build low-carbon, climate-resilient infrastructure?
For environmentalists, the answer is a resounding yes. In the near-term, such spending can generate demand for labour and supplies, providing the stimulus that developing economies desperately need. In the longterm, it serves to simultaneously modernise and increase the efficiency of energy, manufacturing, mobility and logistics. This will in turn raise productivity and competitiveness, fostering domestic drivers of growth.
What is missing, in many countries, are the policies, institutions and financial partners necessary to generate a pipeline of projects such as wind farms, bus-rapid-transit systems, or geothermal power plants.
In the coming months this unprecedented opportunity will either be seized or squandered in the boardrooms of development banks. Borrowing governments must push smart infrastructure to the front of their project pipelines as their best route to sustainable development and poverty reduction. And donor nations, through their shareholdings, must do everything possible to facilitate financing for these projects.
If they do not, 2015 may be remembered solely for its good intentions.
