The impacts of climate change fall heaviest on the poor. Just take the island of Puerto Rico which was particularly badly hit by hurricane Maria last week – and where 44 per cent of people already live below the poverty line. Even on the US mainland, those living in lower-income communities are more likely to live in unsafe homes in flood-prone areas, or closer to noxious industrial facilities.
This makes a global reduction of CO2 emissions essential. But some places are also taking the opportunity to extend social justice even further: a new Cities100 report shows how some cities are marrying their climate change response with support for their most vulnerable communities.
Some 91 different cities submitted 174 applications to the campaign. Then a team from the international think tank Sustainia whittled them down into a top 100 list of city-based solutions to climate change.
Here are just 16 examples, chosen to highlight the wider good tackling climate change can also achieve.
Emissions and equality
Washington D.C now has a law requiring all energy suppliers to source 50 per cent of their electricity from renewable energy sources by 2032 – including 5 per cent from local solar energy. All non-conforming suppliers must pay a fee, which then helps provide solar energy benefits to low and moderate income residents.
In Suwon in South Korea, the Sharing Solar Power Project is a grassroots cooperative that invests in solar energy and then ploughs 50 per cent profits back into social welfare or additional solar projects. As of February 2017 the city has seen $200,000 in profits.
In London, mayor Sadiq Khan has introduced schemes to replace and repair inefficient gas boilers in homes. The Boiler Cashback scheme has provided around 4,000 homeowners and landlords with cashback to replace boilers operating at less than 70 per cent efficiency. A second Better Boilers scheme also focuses on reducing fuel poverty among the most vulnerable communities in London.
Los Angeles has installed 1,000 publically available electric chargers, more than half of the city’s own light-duty fleet is now electric, and they’ve piloted an EV car-sharing scheme to encourage equitable access in low and middle income areas. An Electric Vehicle Request for Information initiative has also bundled together EV demand from several cities in order to drive down prices: in March 2017, the order stood at 114,000 vehicles at a value of $10bn.
Adaptation for all
New Orleans is investing in an emergency account program. This matches financial savings for low and moderate income earners to create emergency funds for disaster response. A workforce development program for environmental projects is also hoping to help tackle the city’s employment problems.
Mexico City is harvesting its rainwater in order to reduce pressure on its over-stretched groundwater systems. And it is training women who have suffered domestic violence to install and monitor the new technology.
Gladsaxe in Denmark has turned a 142-hectar water catchment area into a massive site for recreation and sports. “Paddle tennis” courts, skateboarding areas and climate frames all double as rainwater reservoirs. And the Park includes a non-profit social housing association with its own rainwater distribution system.
In Taoyuan in Taiwan, the city has built a water monitoring system and app that allows people to access disaster information in real time – and to help report on floods themselves. 20,000 people have downloaded the app so far.
San Francisco now requires large commercial buildings to audit their energy saving opportunities. Over four years, 468 municipal buildings have cut carbon emissions by more than 30 per cent. In the private sector, audits have led to a 10 per cent reduction in electricity use in upgraded buildings. The reporting requirements have also already created 200 new jobs.
Johannesburg has waste buy-back centres, which encourage entrepreneurialism by buying recyclable paper, plastic, cans and glass from informal waste pickers and selling it on to recyclers. This gives the waste-pickers greater job security and more predictable demand.
In Cape Town a new industrial program called WISP (Western Cape Industrial Symbiosis Programme) is linking up companies who can benefit from eachothers waste. Workshops have identified more than 4,000 such relationships between 486 different companies in the network. It has also developed a carbon calculator so it can measure how much CO2 these swaps will save. “WISP has diverted 4,950 metric tons of waste from landfill – saving CO2 equivalent to 15,000 trees growing over 30 years.” the report says.
T.Park in Hong Kong is the world’s largest wastewater sludge incineration plant, converting 2,000 tons of daily sludge into less polluting ash and renewable energy. There is also an environmental education centre complete with spa, wetland garden and bird sanctuary.
Barcelona plans to minimise the urban heat island effect by increasing its number of trees from 5 per cent canopy coverage to 30 per cent by 2037. As well as providing shade, the extra trees will help remove more than 305 metric tons of pollution from the atmosphere.
Wuhan in China has abandoned its previous flood defence strategy of giant dikes that lined the river banks, and has instead created a new, 7km long Beach Park. The venue is set to become the largest urban riverfront park in the world at 10m m2: 45,000 trees, 350,000m2 of shrubs and 387,000m2 of grass fill its banks, while football courts, non-motorised roads, and seven swimming pools will draw people to the area.
A sharing economy
New Taipei City in China is encouraging people to recycle with service stations where you can exchange waste for garbage bags and green products. Some of these also include “happiness stations”, where working home goods can be donated to low-income communities.
Mexico City has introduced green bonds for climate action. $50m worth of bonds have been issued to finance the city’s green transition, including a new bus rapid transit lines and LED street lighting. The program also seeks to reduce the inequality gap between men and women caused by the impacts of climate change.
