Q & A

What are the large-scale environmental challenges faced by communities worldwide?

The large-scale environmental challenges faced by communities worldwide include dangerous irreversible climate change, which often stems from cities and resource-intensive urban lifestyles.

What is the potential impact of urban investment decisions on future infrastructure and lifestyles?

Urban investment decisions taken today will determine whether people will be locked into resource inefficient and fossil fuel dependent infrastructures and lifestyles or if they will enable cities to become places where we can live attractive, healthy, and sustainable lives.

What is the significance of the next 30 years for global urban population and infrastructure?

The next 30 years are significant because it is expected that the global urban population will double, along with the global urban infrastructure, presenting a short window of opportunity to make sustainable choices.

What are the key actions cities need to take to address urban challenges?

Cities need to become low carbon by shifting from fossil fuels to renewable energy, build resilience to face the impacts of climate change, and utilize existing ecosystems and biodiversity to support sustainability.

What is Vancouver's goal regarding renewable energy by 2050?

Vancouver has adopted one of the most ambitious climate action plans with the goal of running the city on 100% renewable energy by 2050.

How has Vancouver engaged its citizens in creating a greener city?

Vancouver engaged its citizens by creating an action plan with 10 targets in various areas such as water, food, clean air, green business, green jobs, and waste reduction, involving over 35,000 residents and 180 organizations in writing and implementing the plan.

What is the role of renewable energy technologies in transforming cities?

Renewable energy technologies play a disruptive role in transforming cities by being radically different and better for consumers and society, leading to a quick disruption of current paradigms once the technology is mature.

What is the significance of electric vehicles in reducing greenhouse gas emissions?

Electric mobility is essential for meeting deep greenhouse gas emissions reduction targets, with a significant potential demand from consumers willing to pay extra for electric vehicles.

How does the Vancouver Convention Center exemplify sustainable building design?

The Vancouver Convention Center features sustainable elements such as a six-acre living roof, black water recycling treatment plant, and the use of sea water for heating and cooling, minimizing its environmental impact.

What is Seoul's goal for electricity self-reliance and how does it plan to achieve it?

Seoul aims to achieve 20% electricity self-reliance by 2020, with renewable energy playing a key role. Initiatives include installing solar panels on top of a filtering reservoir of a water purification plant to increase efficiency.

How does Gothenburg, Sweden, approach climate strategies and cooperation?

Gothenburg is recognized for its innovative climate strategies, including the introduction of green bonds and cooperation with academia and the financial sector, such as collaborating with AB Volvo to create a new electric bus.

What is the concept of 'consumption-based carbon footprint' and how does Gothenburg apply it?

Gothenburg calculates its consumption-based carbon footprint by considering emissions from the production of goods and services consumed by its residents, even if those emissions occur outside the city's borders, leading to a broader focus on climate issues.

How does Paris plan to tackle air pollution and promote sustainable mobility?

Paris plans to tackle air pollution by incentivizing sustainable mobility, subsidizing the purchase of clean electric vehicles and electric bicycles, and gradually banning the most polluted cars from the city by 2020.

What is the role of national politicians and policies in achieving sustainable cities?

National politicians and strong policies are essential to support cities in achieving their ambitious goals. A combination of top-down and bottom-up approaches involving city residents is necessary for success.
