LONDON, UK, April 12, 2017 (Maximpact.com News) – The world’s largest cities are not sitting around waiting for national governments to hand them a climate-safe future. They are taking the initiative to build their own low-carbon opportunities.

To address climate change arising from urban development, there are over 3,000 low-carbon infrastructure projects in the planning stages across a network of 90 of the world’s megacities known as C40 Cities .

Cities have reported costs for just 15 percent of these projects, but even this small percentage amounts to US$15.5 billion in required investment.

There are 90 megacities in the C40 Cities network. They include: Durban, Nairobi, Lagos, and Addis Ababa in Africa; Delhi, Hong Kong, Bangkok, and Tokyo, in Asia; Auckland, New Zealand in Oceana; Amman, Jordan in the Middle East; Copenhagen, Paris, Rome, London, Berlin, Athens and Amsterdam in Europe; Bogota, Rio de Janeiro, Sao Paulo, and Buenos Aires in South America; and in North America, Houston, New York, San Francisco, Washington, DC, and Vancouver.

Roughly one in every 12 people in the world lives in a C40 city, and these 90 cities generate about one-quarter of the world’s wealth, as expressed by GDP, or Gross Domestic Product.

These numbers highlight an enormous opportunity for collaboration between cities and the private sector to invest in sustainable projects, and also the need to accelerate investment and development in sustainable infrastructure to deliver a climate-safe future.

Rachel Kyte, chief executive, Sustainable Energy for All, an initiative of the United Nations Secretary-General, has said, “Buildings account for one-third of global energy use and with cities growing rapidly, there’s an urgent need for partnerships that help cities and citizens use energy better.”

Recent C40 research, contained in the report “Deadline 2020,” estimates that C40 cities need to spend US$375 billion over the next four years on low carbon infrastructure in order to be on the right track to meet the ambition of the Paris Agreement on Climate that took effect in November 2016.

Under this agreement, world governments pledged to keep Earth’s temperature increase to less than two degrees Celsius above pre-industrial levels.

Deadline 2020” estimates before 2050, C40 cities will need to invest over US$1 trillion on new climate action and in renewing and expanding infrastructure to get on the trajectory required to meet the goal of the Paris Agreement.

But how are the megacities to attract this mega-investment?

On April 4, the C40 Financing Sustainable Cities Forum gathered over 200 delegates from cities, investors, national governments, academics, private sector experts, civil society groups and technology providers to identify the key barriers in financing sustainable urban infrastructure.

The Forum was hosted in London by the C40 Cities Climate Leadership Group and the Greater London Authority, with the support of the Citi Foundation and World Resources Institute’s Ross Center for Sustainable Cities.

City action can deliver 40 percent of the Paris goal,” Mark Watts, executive director, C40 Cities, said at the Forum.

Participants looked at unlocking finance for low-carbon investments in cities. They agreed that cities must improve project development information in order to accelerate climate action, a conclusion articulated in a new report, “The Low Carbon Investment Landscape in C40 Cities.

They recognized that accessing and attracting finance are some of the biggest barriers that mayors face in delivering their climate change plans, especially in developing countries and emerging economies with a lack of expertise in securing investment.

To help solve this problem, the C40 Cities Finance Facility was launched during COP21, the 2015 United Nations Climate Change Conference in Paris, where the Paris Agreement on Climate was approved by world governments.

The C40 Cities Finance Facility will provide US$20 million of support by 2020 to help unlock and access up to US$1 billion of additional capital funding, by providing the connections, advice and legal and financial support to enable C40 cities in developing and emerging countries to develop more financeable projects.

For developing markets, public-private partnerships are key to getting sustainable projects off the ground,” said Val Smith, director, Corporate Sustainability at Citi.

But the financial industry tells C40 Cities that they are experiencing a lack of corporate understanding of the low carbon technology being deployed.

They lack understanding of the financing models cities use to fund low carbon infrastructure and, in addition, financiers are seeing inadequate capacity within city governments to form partnerships and collaborate on sustainable infrastructure projects.

CDP’s Matchmaker program aims to overcome these challenges by engaging cities early in the project development process and standardizing how these projects are disseminated to the market.

CDP, formerly the Carbon Disclosure Project, is a not-for-profit that runs the global disclosure system for investors, companies, cities, states and regions to manage their environmental impacts.

Since the Paris Agreement was adopted in 2015, CDP says they have seen a 70 percent increase in cities disclosing their carbon emissions.

CDP says this year’s disclosures reveal that many cities are actively looking to partner with the private sector on climate change. Cities highlighted a total 720 climate change-related projects, worth a combined US$26 billion, that they want to work with business on.

Matchmaker will publicize these low-carbon infrastructure projects to CDP’s growing number of investor signatories that currently represent over US$100 trillion in assets.

And these are by no means all of the opportunities for sustainable investment in urban low-carbon construction.

On April 4, at a meeting of the Sustainable Energy for All Forum in New York City April 3, five new cities and districts committed to improve their buildings by adopting new policies, demonstration projects and tracking progress against their goals.

They joined the Building Efficiency Accelerator (BEA), a public-private collaboration that now includes over 35 global organizations and 28 cities in 18 countries.

The cities and districts joining the BEA are Kisii County, Kenya; Merida, Mexico; Nairobi City County, Kenya; Pasig City, Philippines; and Ulaanbaatar, Mongolia.

World Resources Institute (WRI) leads the BEA, convening businesses, nonprofits and multilateral development organizations to support local governments in implementing policies and programs that make their buildings more efficient.

Jennifer Layke, global director, Energy Program, World Resources Institute, encapsulated the push for sustainable construction, saying, “People want schools, homes, and offices that are healthy and comfortable without the burden of high energy costs due to inefficiency. Prioritizing efficiency in buildings can save money and reduce pollution. Our new Building Efficiency Accelerator partners are signaling their intent to avoid the lock-in of decades of inefficient development.

Supporting these new members are ICLEI – Local Governments for Sustainability, the India Green Building Council, the Kenya Green Building Society, Pasig and WRI Mexico.

We must transform our urban systems to meet the challenges of sustainability and climate,” said Naoko Ishii, CEO and Chairperson of the Global Environment Facility, a funding organization. “Through this partnership, we can provide awareness raising, policy advice and technology transfer directly to sub-national governments ready to take action.”

Ranking the Top 10 Global Green Cities

 SINGAPORE, August 3, 2016 (Maximpact.com News ) – Mirror, mirror on the wall, whose city is the greenest of them all? The mirror held up by the corporate strategy consulting firm Solidiance reflects the answer in a new report  that compares the performance of 10 global cities and their green buildings.

To rank these cities’ green building performance, Solidiance developed a set of criteria across four categories. Three focused on the total number of green buildings, their performance and their initiatives, while one category examined each city’s supportive infrastructure, which has a lot to do with fostering a healthy green building movement.

After assessing the 10 Global Cities for green building performance, Paris was determined to be the leader, followed by Singapore and London

Sydney, Tokyo and Hong Kong came in the fourth, fifth and sixth positions, while New York, Dubai, Beijing, and Shanghai filled in the other four slots.

 “Singapore can certainly be considered a leader in the field of green building. The city target for 80 per cent of buildings to achieve BCA Green Mark standards by 2030 is ambitious but achievable, and the Singapore Green Building Council will play a key role in delivering this,” said Terri Wills, CEO of World Green Building Council, United Kingdom.

 Singapore is the “standout leader” in the Green Building Codes and Targets assessment Solidiance reports. While all the Global Cities have outlined city-level green building codes, only three cities have achieved their green building targets. Singapore, Beijing and Shanghai are the only cities with both a green building code and green building targets set out by the city.

Paris and Singapore took the top spots by excelling in all four assessment categories: city-wide green building landscape, green building efficiency and performance, green building policies and targets, and green city culture and environment.

They were the only cities that ranked within the Top Five in every category.

Both Paris and Singapore have strong building efficiency and performance, which shows that both local and international certification standards are yielding high-performance on green buildings.

 London benefits from high yield of green buildings in the city, which can be linked to the fact that the United Kingdom was the first country ever to introduce a green building certification system.

Paris fell just slightly short of Singapore in the absolute number of green buildings in the city, and by not setting out a clear city-wide green building target.

Although Sydney, Tokyo, and Hong Kong performed well on the green city culture and environment criteria, Sydney and Hong Kong were negatively affected with the poor results they achieved on their green building landscape and performance.

Sydney, with 67, had the fewest absolute number of green buildings in the city.

Finally, Dubai, Beijing, and Shanghai were the last cities on the Top 10 list. These three cities are among the most recent to join the green building movement, and Solidiance analysts expect that these rankings will change in the future as these newer ‘green building cities’ are setting ambitious targets in order to catch up to other cities’ levels.

Dubai launched its local green building standard last among these 10 Global Cities, in 2010, resulting in fewer locally certified buildings (8th), and only launched its green building regulations and specifications in 2012.

Despite the slow start, Dubai ranks 5th in internationally certified green buildings (104), and has a total of 147 internationally and locally certified green buildings erected on its cityscape. Dubai already ranks 6th for ‘green buildings as a percentage of total buildings’

The current green building development has been focused on new buildings but is shifting towards existing buildings,” said Vincent Cheng, director of building sustainability at ARUP, Hong Kong, an independent firm of designers, planners, engineers, consultants and technical specialists. “For significant progress, the focus of stakeholders in Hong Kong should shift from new to existing buildings which make up the bulk of the building stock. Potentially, more effort can be made to incentivize sustainability for existing buildings, promote microgrid/ renewable systems to reduce dependence on coal-powered electricity, and divert waste from precious landfill space.

When considering the limited number of years that Beijing, Dubai and Shanghai have been working to green their built stock, the achievements of these cities are profound, especially when considering the large number of highly internationally-certified buildings currently standing within these cities,” says Solidiance, explaining the rankings.

Saeed Al Abbar, chairman of the Emirates Green Building Council, United Arab Emirates, states in the study, “It is important to note that a building can be sustainable and incorporate green best practices without having a certification behind it. Certifications, however, are useful tools for measurement and can serve as guidelines for best practice. Nonetheless, Dubai does not have a specific certification or rating systems such as Estidama in Abu Dhabi, but the Leadership in Energy and Environmental Design (LEED) rating system is used and recognised broadly.”

By contrast, Singapore stood out as a pioneer in the industry by setting forth a comprehensive and bold set of policies and targets for greening the city’s built block.

As a city that has committed to greening 80 percent of its built stock by 2030, Singapore proved to be one of the most ambitious on the list of cities evaluated.

Finally, the assessment of the city-level green initiatives established that both Sydney and Hong Kong have set higher than average carbon dioxide (CO2) reduction targets amongst the 10 Global Cities, and have also proven themselves as they perform noticeably well with low CO2 emissions city-wide.

 Paris, Sydney, and Singapore take the highest ranking spots with regards to each city’s green building efficiency. This is due to the three cities not only being very low CO2-polluting cities in general, but also because they each have a very low percentage of emissions which can be attributed to the city’s built-environment.

Roughly eight to 10 million new buildings are constructed each year, worldwide, and now more of them are greener than ever before. Solidiance finds that the number of green buildings is doubling every three years as a response to the current accelerating demand for sustainability.

 Michael Scarpf, head of sustainable construction at the Swiss building materials giant LafargeHolcim told Solidiance, “Singapore and London are the cities which have the highest green building activity, and Costa Rica, France, Singapore, and the United Kingdom are the countries that witness high demand for green building materials.

Buildings are the largest energy-consuming sector, accounting for more than 40 percent of global energy use and responsible for an estimated 30 percent of city-wide emissions, calculates Solidance, which points out that buildings also hold the most promise for global energy savings.

New Bioglass Can Re-Grow, Replace Cartilage

By Sunny Lewis

LONDON, UK, May 17, 2016 (Maximpact.com News) – Scientists have developed a new material that can mimic cartilage and potentially encourage it to re-grow.

Cartilage is the flexible connective tissue found in joints and between vertebrae in the spine. Compared to other types of connective tissue, it is tough to repair.

 Researchers from Imperial College London and the University of Milano-Bicocca have developed a bioglass material that mimics the shock-absorbing and load bearing qualities of real cartilage.

They are now hoping to use it to develop implants for replacing damaged cartilage discs between vertebrae.

They believe it also has the potential to encourage cartilage cells to grow in knees, which has not been possible with the methods in use today.

The new material also could help the millions who suffer from arthritis. The most common type of arthritis, osteoarthritis, involves wear-and-tear damage to cartilage — the hard, slick coating on the ends of bones.

“Bioglass has been around since the 1960s, originally developed around the time of the Vietnam War to help heal bones of veterans, which were damaged in conflict. Our research shows that a new flexible version of this material could be used as cartilage-like material,” said Professor Julian Jones, one of the developers of the bioglass from the Department of Materials at Imperial.

“Patients will readily attest to loss of mobility that is associated with degraded cartilage and the lengths they will go to try and alleviate often excruciating pain,” said Jones

“We still have a long way to go before this technology reaches patients,” he said, “but we’ve made some important steps in the right direction to move this technology towards the marketplace, which may ultimately provide relief to people around the world.”

The bioglass consists of silica and a plastic or polymer called polycaprolactone. It displays cartilage-like properties – it is flexible, strong, durable and resilient.

It can be made in a biodegradable ink form, enabling the researchers to 3D print it into structures that encourage cartilage cells in the knee to form and grow – a process that they have demonstrated in test tubes.

It also displays self-healing properties when it gets damaged, which could make it a more resilient and reliable implant, and easier to 3D print when it is in ink form.

 One formulation developed by the team could provide an alternative treatment for patients who have damaged their intervertebral discs.

When cartilage degenerates in the spine it leaves patients with debilitating pain.

Current treatment involves fusing the vertebrae together, reducing the patient’s mobility.

The scientists believe they will be able to engineer synthetic bioglass cartilage disc implants, that would have the same mechanical properties as real cartilage, but which would not need the metal and plastic devices that are currently available.

Another formulation could improve treatments for those with damaged cartilage in their knee, say the team. Surgeons can currently create scar-like tissue to repair damaged cartilage, but ultimately most patients have to have joint replacements, which reduces mobility.

The team are aiming to print tiny, biodegradable scaffolds using their bioglass ink. These bio-degradable scaffolds would provide a template that replicates the structure of real cartilage in the knee.

When implanted, the combination of the structure, stiffness and chemistry of the bioglass would encourage cartilage cells to grow through microscopic pores. The idea is that over time the scaffold would degrade safely in the body, leaving new cartilage in its place that has similar mechanical properties to the original cartilage.

The researchers have received funding from the Engineering and Physical Sciences Research Council (EPSRC) to take their technology to the next stage.

They aim to conduct trials in the lab with the technology and develop a surgical method for inserting the implants. They will also work with a range of industrial partners to further develop the 3D manufacturing techniques.

Professor Justin Cobb, the Chair in Orthopaedic Surgery at Imperial’s Department of Medicine, will be co-leading on the next stage of the research.

Professor Cobb explained, “This novel formulation and method of manufacture will allow Julian and his team to develop the next generation of biomaterials. Today, the best performing artificial joints are more than a thousand times stiffer than normal cartilage. While they work very well, the promise of a novel class of bearing material that is close to nature and can be 3D printed is really exciting.”

“Using Julian’s technology platform we may be able to restore flexibility and comfort to stiff joints and spines without using stiff metal and all its associated problems,” said Cobb.

Professor Laura Cipolla, from the Department of Biotechnology and Biosciences at the University of Milano-Bicocca, explained some of the more technical aspects of the research. “Based on our background on the chemical modification of bio- and nanostructured materials, proteins, and carbohydrates,” she said, “we designed a new chemical approach in order to force the organic component polycaprolactone to stay together in a stable way with the inorganic component silica.”

The technology still has a number of regulatory hurdles to overcome before it reaches clinical applications for both applications. The team predicts it will take 10 years to for both technologies to reach the market. They have patented the technology with Imperial Innovations – the College’s technology commercialization partner.
