New research from the New Climate Economy finds that investing in public and low emission transport, building efficiency, and waste management in cities could generate savings with a current value of US$17 trillion by 2050. These low-carbon investments could also reduce greenhouse gas emissions by 3.7 Gt CO2e per year by 2030, more than the current annual emissions of India.
With complementary national policies such as support for low-carbon innovation, reduced fossil fuel subsidies, and carbon pricing, the savings could be as high as US$22 trillion.
“The steps that cities take to shrink their carbon footprints also reduce their energy costs, improve public health, and help them attract new residents and businesses,” said Michael R. Bloomberg, UN Secretary-General’s Special Envoy for Cities and Climate Change. “This report can help accelerate the progress cities are making in all of these areas, by highlighting smart policies and encouraging cooperation through efforts like the Compact of Mayors.”
The report recommends that cities commit to low-carbon urban development strategies by 2020. It also recommends cities commit to the Compact of Mayors, a global coalition of mayors and city officials pledging to reduce local greenhouse gas emissions, enhance resilience to climate change, and track their progress transparently. More than 130 cities – representing more than 220 million people – have already committed to the Compact of Mayors and will be setting ambitious emissions reduction targets and reporting publicly.
“Better, more resilient models of urban development are particularly critical for rapidly urbanizing cities in the developing world,” said Eduardo Paes, Mayor of Rio de Janeiro and Chair of C40 Cities. “Cities around the world are already leading the way in implementing sustainable and innovative urban solutions. By sharing and scaling-up these best practices through international collaboration, cities can save money and accelerate global climate action.”
“Developing country cities have a major opportunity to lead the low-carbon future”, said Parks Tau, Mayor of Johannesburg. “In Johannesburg, the Rea Vaya Bus Rapid Transit and the highly competitive R1.5bn green bond both demonstrate a commitment to economic growth and investment rooted in resilient, sustainable urban development.”
Creative policy instruments and innovative financing can help cities overcome barriers to action, the report says. For every US$1 invested in improving the creditworthiness of cities, more than US$100 can be leveraged through private finance for low-carbon urban infrastructure. And every US$1 million invested in project preparation could yield US$20–50 million in capital support for successful projects.
The report offers numerous examples of cities that have achieved or can achieve economic benefits from green investments.
- Bus Rapid Transit: The economic returns of Johannesburg’s Bus Rapid Transit system in its first phase were close to US$900 million.
- Building efficiency: Singapore’s “Green Mark” program, for instance, which aims to cover 80% of its buildings by 2030, could see a reduction in building electricity use of 22% and net economic savings of over US$400 million.
- Cycling: Copenhagen’s planned Cycle Super Highways are estimated to have an internal rate of return on investment of 19% per year.
Nick Godfrey, Head of Policy and Urban Development at the New Climate Economy and an author off the report, provided context for the report’s analysis. “US$17 trillion in savings is actually a very conservative estimate,” he said, “because it only looks at direct energy savings generated from investment, which are a small proportion of the wider social, economic, and environmental benefits of these investments.”
The report also recommends that the international community should develop an integrated package of US$1 billion or more over five years to help accelerate and scale up low-carbon urban strategies in at least the world’s largest 500 cities.

A Good Look At How Homes Will Become More Energy Efficient Soon
Everyone always talks about ways they can save energy at home, but the tactics are old school. They’re only tweaking the way they do things at the moment. Sealing holes in your home isn’t exactly the next scientific breakthrough we’ve been waiting for.
There is some good news because technology is progressing quickly. Some tactics might not be brand new, but they’re becoming more popular. Here are a few things you should expect to see in homes all around the country within a few years.
1. The Rise Of Smart Windows
When you look at a window right now it’s just a pane of glass. In the future they’ll be controlled by microprocessors and sensors. They’ll change depending on the specific weather conditions directly outside.
If the sun disappears the shade will automatically adjust to let in more light. The exact opposite will happen when it’s sunny. These energy efficient windows will save everyone a huge amount of money.
2. A Better Way To Cool Roofs
If you wanted to cool a roof down today you would coat it with a material full of specialized pigments. This would allow roofs to deflect the sun and they’d absorb less heat in the process too.
Soon we’ll see the same thing being done, but it will be four times more effective. Roofs will never get too hot again. Anyone with a large roof is going to see a sharp decrease in their energy bills.
3. Low-E Windows Taking Over
It’s a mystery why these aren’t already extremely popular, but things are starting to change. Read low-E window replacement reviews and you’ll see everyone loves them because they’re extremely effective.
They’ll keep heat outside in summer or inside in winter. People don’t even have to buy new windows to enjoy the technology. All they’ll need is a low-E film to place over their current ones.
4. Magnets Will Cool Fridges
Refrigerators haven’t changed much in a very long time. They’re still using a vapor compression process that wastes energy while harming the environment. It won’t be long until they’ll be cooled using magnets instead.
The magnetocaloric effect is going to revolutionize cold food storage. The fluid these fridges are going to use will be water-based, which means the environment can rest easy and energy bills will drop.
5. Improving Our Current LEDs
Everyone who spent a lot of money on energy must have been very happy when LEDs became mainstream. Incandescent light bulbs belong in museums today because the new tech cut costs by up to 85 percent.
That doesn’t mean someone isn’t always trying to improve on an already great invention. The amount of lumens LEDs produce per watt isn’t great, but we’ve already found a way to increase it by 25 percent.
Maybe Homes Will Look Different Too
Do you think we’ll come up with new styles of homes that will take off? Surely it’s not out of the question. Everything inside homes seems to be changing for the better with each passing year. It’s going to continue doing so thanks to amazing inventors.

IEMA Urge Government’s Industrial Strategy Skills Overhaul To Adopt A “Long View Approach”
IEMA, in response to the launch of the Government’s Industrial Strategy Green Paper, have welcomed the focus on technical skills and education to boost “competence and capability” of tomorrow’s workforce.
Policy experts at the world’s leading professional association of Environment and Sustainability professionals has today welcomed Prime Minister Teresa May’s confirmation that an overhaul of technical education and skills will form a central part of the Plan for Britain – but warns the strategy must be one for the long term.
Martin Baxter, Chief Policy Advisor at IEMA said this morning that the approach and predicted investment in building a stronger technical skills portfolio to boost the UK’s productivity and economic resilience is positive, and presents an opportunity to drive the UK’s skills profile and commitment to sustainability outside of the EU.
Commenting on the launch of the Government’s Industrial Strategy Green Paper, Baxter said today:
“Government must use the Industrial Strategy as an opportunity to accelerate the UK’s transition to a low-carbon, resource efficient economy – one that is flexible and agile and which gives a progressive outlook for the UK’s future outside the EU.
We welcome the focus on skills and education, as it is vital that tomorrow’s workforce has the competence and capability to innovate and compete globally in high-value manufacturing and leading technology.
There is a real opportunity with the Industrial Strategy, and forthcoming 25 year Environment Plan and Carbon Emissions Reduction Plan, to set long-term economic and environmental outcomes which set the conditions to unlock investment, enhance natural capital and provide employment and export opportunities for UK business.
We will ensure that the Environment and Sustainability profession makes a positive contribution in responding to the Green Paper.”
