What is this? Read on to find out.

Riddle us this. In what country are...
  • 450 million ceiling fans already in use, 40 million new ones sold every year?
  • 350 million fluorescent tube lights already in use, 10 million new sold every year?
  • 30 million air conditioners already in use, three million new sold every year?
If you guessed India, you are right.

With a population of about 1.2 billion, India is one of the largest consumer markets in the world. So it’s no surprise that household appliances account for several gigawatts of electricity usage across the country. As India’s middle class grows and people move from villages to towns and cities, electricity usage is only increasing. In fact, hundreds of millions of electric appliances will be added over the next few decades. This poses a serious challenge for India’s energy security since there already are electricity supply shortages, which often lead to chronic outages and blackouts. The surge in household appliances is also a climate change challenge—India, the world’s third-largest CO2 emitter, is predicted to continue increasing its greenhouse gas emissions at least until 2030.

But India is turning this challenge into an opportunity by tapping into energy efficiency solutions, a relatively new area with already a few major successes. Considered globally as the “first fuel,” energy efficiency is rising to the forefront of India’s quest for innovative solutions to provide 24/7 reliable and affordable electricity for all.

Why dialogue between government and the private sector is essential to fight climate change

Cecile Fruman's picture



The historic agreement reached in Paris at the 21st Conference of the Parties (COP21) last December sets out an ambitious plan for signatory countries to achieve specific targets for reduced greenhouse-gas (GHG) emissions. The Paris Agreement includes significant financial commitments and the establishment of structures and mechanisms by which countries will design and implement viable policies to meet agreed-upon goals.

COP21’s major message is one of collaboration: The Paris Agreement unites 177 nations in a single agreement to tackle climate change. Governments set the goal at COP21, but they will need action by the private sector to meet it. One cannot operate without the other.

Industries, which are responsible for 21 percent of direct GHGs worldwide, long resisted the idea of going green, fearing high costs. However, dramatic recent decreases in the cost of climate-friendly technologies, as well as the introduction of carbon pricing, has changed industry perspectives.

More and more businesses are now embracing climate-smart investments, and the driver of such change is, not least, self-interest. A recent study looked at a sample of 1,700 leading international firms and found that money put into reducing GHG emissions saw an internal rate of return of 27 percent – a clear indication that those investments are paying off.

The Science Based Targets initiative is one illustration of industry’s commitment to playing its part in decarbonizing the global economy. The initiative is a partnership between Driving Sustainable Economies, the UN Global Compact, the World Resources Institute and the World Wildlife Fund, helping companies determine how much they must cut emissions to prevent the worst impacts of climate change. So far, 155 companies have signed up for the initiative: Thirteen of them have successfully developed science-based targets which, by themselves, are projected to reduce emissions by 874 million tons of carbon dioxide – the equivalent of the yearly emissions of 250 coal-fired power plants.

Can transit-oriented development change travel behavior in cities?

It is pretty easy to understand how and why land use patterns around public transit stations can influence the way we move around the city.

As more and more people live and work in a neighborhood with a limited land area, it becomes increasingly challenging to drive around without encountering congestion or to find a parking space easily. In this situation, public transit and non-motorized transport (NMT) become attractive alternatives for people who otherwise are reluctant to give up the comfort and flexibility of driving.

Conversely, as street blocks get bigger, people may find it takes too long to access public transit stations, which discourages the use of public transport facilities.

As straightforward as the logic may sound, the nature and magnitude of such influence are yet to be evaluated with solid empirical evidence. To take a closer look at the linkages between land use and travel behavior, I decided to study the case of Boston in the United States. I chose Boston because it boasts an effective public transit system, and was one of the first American cities to embrace transit-oriented development (TOD), an urban planning approach that promotes compact and mixed use development around public transit facilities.

Using technology to stay ahead of disaster risk

We’re witnessing an unprecedented uptick in record-breaking storms. In October last year, Hurricane Patricia came ashore in Mexico with record breaking 200 miles per hour winds. A few months later on the other side of the world, Cyclone Winston broke records for Pacific basin wind speeds, destroying parts of mainland Fiji with 180 miles per hour winds. More recently, Cyclone Fantala became the most powerful storm in the Indian Ocean ever recorded.
 
Experts agree that its activities by people which are increasing the severity of storms like these. Climate change isn’t just projected to increase the intensity of hurricanes and cyclones, but a whole other range of other natural hazards, like droughts, floods, storms, and heat waves.

The World Bank has a new Climate Action Plan. What's in it for cities?

Ede Ijjasz-Vasquez's picture
The World Bank Group’s Climate Action Plan, adopted last month, is designed to help countries meet their COP21 pledges and manage increasing climate impacts.
 
To achieve these goals, working with cities will be essential: with almost 80% of GHG emissions emanating from urban areas, cities are among the biggest contributors to climate change... and must, inevitably, become a big part of the solution.
 
Cities are also particularly vulnerable to climate risk and other forms of natural hazards, with many of them located in disaster-prone areas. Therefore, enhancing disaster resilience in urban settings is another key requirement to build more sustainable cities in the face of climate change.
 
The good news? Many countries are still in the early stages of the urbanization process, meaning they have a unique opportunity to develop sustainable cities right from the beginning - a much more viable option than trying to retrofit them later on.
 
In this video, World Bank Senior Director Ede Ijjasz-Vasquez and Practice Manager Bernice Van Bronkhorst explain how they are working with clients to make climate-smart cities a reality.

Ending a 20-year water crisis in a remote village in Solomon Islands

Evan Wasuka's picture
Surrounded by water, Nanngu’s taps have been without drinking water for the past 20 years.

With the throttle at full tilt, the boat cut through the surf, spraying salt water into the air. 
Around me, the unfolding scenery is breathtaking. White sandy beaches, turquoise blue seas, swaying coconut palms – the textbook image of paradise in the South Pacific.
 
What more could one ask for in paradise?  

Water, is what they will tell you. “They” are the people of Nanngu Village on the island of Santa Cruz in the far east of Solomon Islands. 
 
Out here, water to drink, cook food with, wash and keep clean is hard to come by.
 
The last time they had proper running water was 20 years ago. That came to an end at the hands of a Category Three cyclone, Nina, which hit the islands in 1993.
 
As I write this, we’re on our way to Nanngu to see a new World Bank-supported project bringing water to the village.

A map is worth a thousand words: Supporting forest stewards in addressing climate change

In Nepal, indigenous groups produced a range of training materials, including videos in local languages on forests and climate change, to help more than 100 women and community leaders in the Terai, Hill and Mountain areas better understand what terms like ‘mitigation and adaptation strategies for climate resilience’ mean for them in their daily lives. 

A team of consultants in Kenya, who are members of indigenous communities with an understanding of regional politics and geographical dynamics, worked on increasing community involvement in sustainable forest management through workshops and face-to-face meetings. As part of their work, they collected information on land tenure status within indigenous territories, which will help the country prepare a national strategy for reducing emissions from deforestation.

Urbanization, climate change and jobs in Africa

Anton Cartwright's picture
Concern about climate change is often deemed a luxury; the domain of those that do not have to worry about famine, surviving the pending winter, local conflict, or political instability. But in the next three decades, an anticipated 900 million people will be added to Africa’s cities: a tripling of the current urban population. The small affluent-class aside, the clarion call of Africa’s newly urban population is not around climate change or industrialization, but jobs and access to work.

How can we accommodate climate-related risks in infrastructure?

If you were traveling through Don Muang International Airport in Bangkok, Thailand in the fall of 2011, you already have a picture of the damage to infrastructure assets brought by unprecedented levels of rainfall.  Water flooded every element crucial to airport operations – airplanes, runways, hangars – and all airport infrastructure was shut down until the crisis passed and repairs could be done. There was no option, as the airport was simply submerged.

But what if future infrastructure projects could be built with an option that allowed them to continue to operate even in the most catastrophic climate-related crisis? What if service delay interruptions were not inevitable, and economic losses were not inescapable?
