Q. What is the approximate share of tourism sector to global CO2 emissions?
- Less than 1%
- Between 1 to 6%
- Between 6 to 10%
- More than 10%
The answer is... between 1 to 6%! Tourism, including transport, accommodation and activities (such as museums, theme parks, events or shopping) is responsible of about 5% of global CO2 emissions. Climate is a key resource for tourism and the sector is highly sensitive to the impacts of climate change and global warming, many elements of which are already being felt.;
- given tourism’s importance in the global challenges of climate change and poverty reduction, there is a need to urgently adopt a range of policies which encourages truly sustainable tourism that reflects a ‘quadruple bottom line’ of environmental, social, economic and climate responsiveness;
- the tourism sector must rapidly respond to climate change, within the evolving UN framework and progressively reduce its Greenhouse Gas (GHG) contribution if it is to grow in a sustainable manner; this will require action to: – mitigate its GHG emissions, derived especially from transport and accommodation activities; – adapt tourism businesses and destinations to changing climate conditions; – apply existing and new technology to improve energy efficiency; and – secure financial resources to help poor regions and countries.

Q. Buying a real #Christmas tree, rather than a plastic #tree, has a bigger impact on #climatechange:
The answer is... false! Real fir trees take in carbon dioxide, release oxygen, provide habitat, and can be recycled.
Farmers grow trees especially for the holidays, which may take 8 to 12 years to grow. During that time, the tree is taking in carbon dioxide, releasing oxygen, and providing habitat for birds and animals; it is cleaning the air and helping slow climate change. Real trees can be recycled, there are many programs that pick up holiday trees and grind them up into mulch, which is then it is spread back onto the land to help grow something else—or more trees.
An artificial tree would have to be reused for more than 20 years to be greener than buying a fresh-cut tree annually. These calculations include greenhouse gas emissions, use of resources and human health impacts.
The annual carbon emissions associated with using a real tree every year are just one-third of those created by an artificial tree over a typical six-year lifespan. Most fake trees also contain polyvinyl chloride, or PVC, which produces carcinogens during manufacturing and disposal. For more information, visit:

Q. In 2008, how many people were displaced by extreme weather compared to 4.6 million people by conflict?
- 1 million persons
- 10 million persons
- 20 million persons
- 30 million persons
The answer is... 20 million persons! In 2008, 20 million persons have been displaced by extreme weather events, compared to 4.6 million internally displaced by conflict and violence over the same period.
Gradual and sudden environmental changes are resulting in substantial population movements. The number of storms, droughts and floods has increased threefold over the last 30 years with devastating effects on communities. Over the last thirty years, twice as many people have been affected by droughts as by storms (1.6 billion compared with approx 718m).
Future forecasts vary from 25 million to 1 billion environmental migrants by 2050, moving either within their countries or across borders, on a permanent or temporary basis, with 200 million being the most widely cited estimate. This figure equals the current estimate of international migrants worldwide. Refer to Migration, Climate Change and the Environment for further information.
Which percentage of plant/animal species will face extinction if global temperature increase exceeds 1.5 - 2.5°C?
- 1 - 10%
- 20 - 30%
- 40 - 50%
- 60 - 70%
The #ClimateIQ answer is... 20 - 30%! Climate change is a huge driver of biodiversity loss. Species have been disappearing at up to 1,000 times the natural rate, and this is predicted to rise dramatically. Current trends suggest that an estimated 34,000 plant and 5,200 animal species - including one in eight of the world's bird species - face extinction.
Combinations of drivers could push some systems beyond tipping points at regional scales. On of the best understood examples is the loss of summer Arctic sea ice due to climate change. This relatively rapid and large shift in ecosystem structure and function at regional scale is projected to have large negative impacts on biodiversity, ecosystem services and human well-being if it is not averted. Ultimately all societies and economies would be affected.
Direct and indirect drivers of biodiversity loss are often embedded deep within our systems of policymaking, financial accounting and patterns of production and consumption. More information here:
Q. Health is affected by climate change through different ways. Which are examples of direct or primary exposure pathways?
- flood, storms
- allergens, diseases
- water/air pollution
- food production, stress
The answer is… flood, storms! Human health is affected by the weather, climate variability and climate change. There are three exposure pathways by which climate change affects health:
- Directly through extreme weather and climate events, such as heat, flood, and storms. These are primary pathways;
- Indirectly through changes in natural systems that then affect disease vectors and disease transmission pathways, such as allergens and increased water/air pollution. These are secondary pathways; and
- Pathways heavily mediated through human systems such as under-nutrition, food production, and mental stress. These are tertiary pathways.

Q. Transport sector aims to reach “0 net emission” between 2060-2080. By 2050 the goal is to move from 7.7Gt emissions/year to:
- 7 or 6Gt/year
- 5 or 4Gt/year
- 3 or 2Gt/year
The answer is... 3 or 2Gt/year! During COP22, in Marakech, countries accelerated global climate action as they fast-tracked the political and practical aims of the Paris Climate Change Agreement. For the Transport sector, the goal is to move from 7.7Gt emissions/year down to 3 or 2Gt by 2050, and aim to “zero net emission” between 2060 (most advanced areas) and 2080 (other parts of the world). All modes of transport (road, railway, aircraft, maritime, rivers, transport for people and goods) will need to be part of a global systemic transformation involving consumption pattern and behavioral changes, major technological innovations, the emergence of new mobility ecosystems, and the creation of new business models.
The facilitators of the Global Climate Action transport activities will bring together all relevant stakeholders (public and private sector, think tanks) around a Global Macro-Road Map on Decarbonizing Transport, a reference or compass to set the course towards the long-term direction set in Paris. For more information, please read the COP22 Transport Report.
Q. Which stage of the life-cycle of a pair of jeans has the most impact on the environment?
- Growing the cotton
- Manufacturing of jeans
- Use, wash, and dry jeans
- Disposal of jeans
The answer is... use, wash, and dry jeans! Consumer care is responsible for the most significant energy use and climate impact, representing 37% of the 33.4 kilograms of carbon dioxide emitted during the lifecycle of a jean. This stage, in which consumers wash and dry jeans, is driven by high use of non-renewable energy. Consumer jeans-washing habits vary by region; by washing every 10 times instead of every 2 times after use, consumers can reduce energy/climate change and water consumption impacts by up to 80%.

Q. Which of the following climate change related events took place this past November 4 - 6, in connection to COP22?
The answer is... Conference of Youth 12 (COY12)! This Conference is an international event where youth around the world gather on the theme of climate change in connection with the Conference of the Parties (COP) to the UNFCCC. The COY12 was held in Marrakesh for three days from November 4th to November 6th, right before the COP22. This year it focused on the role of education and capacity building in empowering young people to take action on climate change and to bring about positive change in society. More information here.
The World Summit on Sustainable Development (WSSD) took place in Johannesburg, South Africa, from August 26th to September 4th, 2002. The WSSD discussed direct actions toward meeting difficult challenges, including improving people's lives and conserving our natural resources in a world that is growing in population, with ever-increasing demands for food, water, shelter, sanitation, energy, health services and economic security.
The Meeting of the Parties to the Paris Agreement 2 (CMA2) will take place during COP23, which is expected to be held from November 6th to 17th, 2017. The CMA oversees the implementation of the Paris Agreement and takes decisions to promote its effective implementation.
The Meeting of the Parties to the Kyoto Protocol 11 (CMP11) took place in Paris le Bourget, France, from November 30th to December 11th, 2015. The CMP oversees the implementation of the Kyoto Protocol and takes decisions to promote its effective implementation.

Q. Which percent of global GHG emissions are deforestation and forest degradation accountable for?
The answer is... 17%!
The UN’s Intergovernmental Panel on Climate Change (IPCC) estimated that the forest sector and other sectors that impact land use – through deforestation, forest degradation and other changes in forests – contributes approximately 17 per cent of global greenhouse gas emissions, or approximately 5.8 Gt of carbon dioxide equivalent (CO2-e), per year. These emissions are mainly taking place in tropical developing countries. Therefore, abatement of forest-based emissions is critical to limiting global warming. For more information, please refer to The UN-REDD Programme Strategy 2011-2015.

Q. In the absence of economic growth, how many people could be driven into extreme poverty by climate change by 2030?
- Up to 42 million
- Up to 82 million
- Up to 122 million
- Up to 162 million
The answer is... up to 122 million!
While climate change is but one driver shaping poverty and food insecurity, its impacts are expected to be substantial. Those two trends, and the severity of climate change impacts on them, will be determined largely by future socio-economic development. In the absence of climate change, and with continuing economic progress, most regions are projected to see a decline in the number of people at risk of hunger by 2050. With climate change, however, the population living in poverty could increase, largely due to its negative impacts on incomes in the agricultural sector. A recent World Bank study estimated that, a scenario with high impact climate change, rapid population growth and a stagnant economy indicated that an additional 122 million people would be living in extreme poverty by 2030.
Reduced income in the agricultural sector explains the largest share of increased poverty as a result of climate change. This is because the most severe reductions in food production and increases in food prices occur in Africa and India, which account for a large share of the world’s poor.

Q. Which of the following are examples of initiatives initiated by cities to address climate change?
- Cities’ Compact
- Green Climate Fund
- Kyoto Protocol
The answer is ...C40!
C40 Cities Climate Leadership Group, a network of the world’s megacities, is committed to addressing climate change. Bus rapid transit, municipal building efficiency, green growth and climate risk assessment are examples of some of their networks that connect cities on specific topics. C40 is a founding partner of the Compact of Mayors, partner to the Global Protocol for Community-Scale Greenhouse Gas Emission Inventories and to the carbonn® Climate Registry. Learn more at http://www.c40.org/cities and check if your city forms part of this network.
Another example of initiatives is the Compact of Mayors, which was launched in September 2014 at the Climate Summit by the UN Secretary-General Ban Ki-moon and the UN Special Envoy for Cities and Climate Change, Michael R. Bloomberg. The Compact is the world’s largest coalition of city leaders. Cities will take action by registering their mitigation and adaptation commitments, taking inventories, setting reduction targets and creating action plans. The data on commitments and actions will be available to the public. Learn more about the Compact of Mayors at http://www.compactofmayors.org/.
Q. Test your #ClimateIQ! Which of the following animals produces the most CH4 (methane)?
The answer is... buffaloes! They produce 11% of CH4 emissions!
Greenhouse gas emissions from enteric fermentation consist of methane, CH4, produced in digestive systems of ruminants and to a lesser extent of non-ruminants. In 2011, world total annual GHG emissions from enteric fermentation were 2,071 Mt CO2 eq, about 40% of total emissions!
With respect to average 2000’s levels, global emissions from enteric fermentation are projected to increase by 19% and 32% in 2030 and 2050, respectively, reaching more than 2,500 Mt CO2 eq in 2050.
