CDP’s Global Report on C40 Cities

  • Comments 0

CDP has released a  new report that details how the world's largest city governments -- the cities of the C40 Cities Climate Leadership Group -- are tackling climate change.  As I was reading through this report, I couldn’t help thinking about the emerging role of IT in enabling cities around the world to address resource constraints, rising energy costs and efficiency measures.


With an impressive 48 out of 58 cities responding to CDP this year, this impressive number of cities are demonstrating awareness of the potential dangers from local climate impacts and are taking crucial steps to make their cities more resilient. London, for example, has estimated that 40 billion pounds will be required to meet the Mayor’s target to reduce CO2 emissions by 60% by 2025, and will be addressing energy efficiency in buildings, transportation and other high-impact areas.


Some high-level observations from the report:

·         Nearly all of the cities reporting to CDP consider themselves at risk from climate change, and 43% said they are already dealing with the immediate effects in their cities. The implications for buildings, infrastructure, energy supply, water availability and human health are significant.

·         An impressive 27 cities have set greenhouse gas emissions targets, with two cities (Melbourne and Copenhagen) aiming for 100% emissions reductions by 2030

·         The consideration of climate-related risk will also play an increasing role in businesses' location decisions. 79% percent of cities reporting to CDP believe that the physical impacts of climate change could directly or indirectly threaten the ability of local businesses to operate successfully. As cities grow, maintaining safe, resilient environments for people and business will be increasingly important.

·         The report shows how each of the C40 are incorporating GHG reduction into their cities master plan….so for example, Yokohama Japan identifies “buildings, transport & energy savings” as key focus areas (all areas that IT can help address)

·         Despite the large number of cities reporting a reduction target, only a few of these cities calculate the financial investment required.


Energy-efficient cities provide one of our best opportunities to sustainably support our growing society through economic development, job creation and reduced impact on the environment.  Many of our cities are not energy-efficient…yet. With energy costs and greenhouse gas (GHG) emissions increasing as populations grow, cities that do not become energy-smart are at risk of becoming too expensive to compete economically with cities that do become energy-smart. The integration of information technologies will advance and accelerate their evolution to energy-efficiency so that cities can sustainably provide economic growth and quality of life for generations to come.
