SDG Media Compact: Exclusive Interview with Hoesung Lee, Chair of the IPCC
Lee Hoesung was appointed the Chair of the Intergovernmental Panel on Climate Change (IPCC) in 2015. He is also the Endowed Chair Professor of economics of climate change, energy and sustainable development in the Republic of Korea.
The latest IPCC report says limiting climate change to 1.5 C is not impossible. What needs to be done for that to happen?
When governments set a target in December 2015 of limiting global warming to well below 2ºC above pre-industrial levels while pursuing efforts to hold it at 1.5ºC, they invited the IPCC to prepare a report to provide information on this Goal. They asked the IPCC to assess the impacts of warming of 1.5ºC, the related emissions pathways of greenhouse gases like carbon dioxide that would result in warming of that amount, and the differences between warming of 1.5 and 2ºC or higher.
The new IPCC Special Report on Global Warming of 1.5ºC shows that it is not impossible to limit warming to 1.5ºC but that doing so will require unprecedented transformations in all aspects of society. The report shows that this is a worthwhile goal as the impacts of warming of 2ºC on lives, livelihoods and natural ecosystems are much more severe than from warming of 1.5ºC.
The global temperature has already risen about 1ºC from pre-industrial levels. The report shows that because of past emissions up to the present it will continue to warm. But these emissions alone are not enough to take the temperature to 1.5ºC: it is still possible to hold it at that level.
This requires very strong cuts in emissions of greenhouse gases by 2030, for instance by decarbonization of electricity production, and further cuts after that so that emissions fall to net zero by 2050. Net zero means that any continuing emissions of greenhouse gases, for instance in transport, are compensated by removing carbon dioxide from the atmosphere through measures such as afforestation or other techniques and technologies.
This will be achieved by reducing energy demand, for instance through greater energy efficiency, and changes in energy use, construction, transport, cities and food and diets. Limiting warming to 1.5ºC is possible in terms of physics; the technology and techniques are there; the question is whether people and societies will support politicians in taking these measures.
What do world leaders need to know about the climate science that will affect the prosperity and well-being of their citizens?
World leaders need to know that the climate is already changing because of emissions of greenhouse gases like carbon dioxide from human activities such as energy production and use, transport, and agriculture and other forms of land use.
These changes pose threats to people from increases in extreme weather events such as heatwaves, forest fires, drought, heavy precipitation and floods. The warming climate is causing the sea level to rise. It is affecting biodiversity and making it harder for species to survive or forcing them to move. These are already affecting people’s lives and livelihoods.
If we carry on emitting greenhouse gases the climate will continue to warm and these threats will get worse. The new IPCC report shows there is even a big difference in risks between warming of 1.5ºC and 2ºC: every bit of warming matters.
The report also shows that it is pursuing policies to address climate change, by reducing emissions and adapting to the changes already underway, can creates a more prosperous and sustainable society by fostering innovation and the green economy and building more resilient communities. Economic development and climate action go hand in hand as sustainable development.
How optimistic are you about our ability to limit global warming to 1.5 C?
The new IPCC report shows it is not impossible, in terms of physics or technology, to limit global warming to 1.5ºC. But the unprecedented transformations in society will require continuing technical innovation and changes in behaviour and lifestyle. The question is whether individuals and companies are ready to make those changes and encourage politicians to put the conditions in place to create a prosperous and sustainable low-carbon society.

SDG Media Compact: Exclusive Interview with Patricia Espinosa, Executive Secretary of UNFCCC
Patricia Espinosa was appointed the Executive Secretary of the UN Framework Convention on Climate Change (UNFCCC) in 2016, a year after the adoption of the Paris Agreement to intensify actions and investments needed for a sustainable low carbon future. Prior to that, she was Minister of Foreign Affairs of Mexico.
The IPCC report says that it is not impossible to limit climate change to 1.5͒C? Do you think we can realistically achieve that? Politically, what needs to happen?
History shows that when the human race decides to pursue a challenging goal, we can achieve great things. From ridding the world of smallpox to prohibiting slavery and other ancient abuses through the Universal Declaration of Human Rights, we have proven that by joining together we can create a better world. Today, I believe we can succeed in limiting climate change to 1.5°C – but only if we once again work in solidarity with a powerful unity of purpose.
Humans have evolved to respond to immediate threats and opportunities. We find it more difficult to address problems that play out over years and decades. We must overcome this natural short-sightedness and commit to urgent climate action. The Paris Agreement confirms the political commitment to climate action, and the UN system provides a platform for international collaboration. What we need now is for more leaders and more citizens to recognize climate action as a global priority and to start working together more urgently.
There was a great surge of enthusiasm for action among industries, governments and even regular people after Paris. Do you think that enthusiasm has been sustained and how can their involvement be ramped up?
There is no quick fix for climate change. Effective climate action will require a long-term, full-time commitment by virtually everyone. Every climate policy, every new technology, every personal action that contributes to reducing emissions and building resilience should be recognized and applauded. There will be other surges of excitement, as in 2015 when the Paris Agreement was adopted, but most importantly we need to rely on consistent, steady action. We can sustain enthusiasm by sharing success stories, closely monitoring and publicizing emissions levels and climate trends, and keeping the climate conversation alive on a daily basis.
Climate change is, in many respects, the quintessential multilateral issue. What needs to happen to strengthen multilaterism to tackle climate change?
Climate change is a global phenomenon that requires global solutions. Fortunately, we already have platforms for multilateral action such as the United Nations and forums such as the G20. Meanwhile, thanks to the media and to rapid communications, people are increasingly aware of what is happening in other parts of the world. They see how migration, trade and technology are making us more interdependent than ever before. Although we do see a backlash against global integration in some parts of the world today, I am convinced that the sense of international solidarity will only grow in the years to come. An increasing awareness that we have a shared destiny on this fragile planet will help to strengthen inclusive multilateral action in the years to come.
How do we get people and governments to move beyond commitments to concrete actions?
Governments need to translate the multilateral goals of the Paris Agreement into specific policies. These policies must to reflect national circumstances and priorities. They need to create what we call an “enabling environment” that motivates and rewards companies, communities and individuals to take concrete actions. Through the Paris Agreement we will monitor national and global emissions trends to determine which national policies seem to be working and which need to be reviewed. So in sum we must build on the broad political commitment set out in Paris to craft national policies that encourage and recognize concrete measures by the full range of actors. We are all responsible for emitting greenhouse gases, so we all have a role – whether in our work, or in our personal lives – in taking concrete actions to reduce emissions.
Can you give some examples of success stories that can inspire other countries?
There are many success stories in all regions and all sectors that demonstrate the enormous potential of climate action.
To start with, a growing number of cities and regions have adopted targets to achieve zero net emissions between 2020 and 2050. These targets are often developed in collaboration. Just one example: Nineteen city leaders from the C40 coalition signed the Net Zero Carbon Buildings Declaration to ensure that all new buildings operate with a neutral carbon footprint by 2030. The rise of inclusive multilateralism, where not only national governments but local and regional governments as well as a diverse array of associations and organizations work closely together, is a powerful force for climate action.
Collaboration is also taking place among actors in particular economic sectors. Earlier this year, the global transport sector, which is responsible for some 14 per cent of global greenhouse gas emissions, created the Transport Decarbonisation Alliance. The Alliance recognizes that lowering transport emissions will also help to reduce urban pollution and improve public health. Transport companies and managers are creating innovative solutions, including new materials and designs, the increased use of renewable energy, improved public transport systems, and more efficient management of road, air and other transport networks. Building collaboration within a sector is a great way to raise ambition and to share success stories and best practices.
We also see a growing list of individual corporations adopting emissions targets. Many have signed up to a Science Based Target to ensure that they are in line with the 1.5-2°C temperature limit enshrined under the Paris Climate Change Agreement. To date, over 700 leading businesses around the world have made strategic climate commitments through the We Mean Business coalition’s Take Action campaign.
There are so many more inspiring examples from a wide range of actors. Their efforts, more than anything else, is what gives me hope that we can achieve the objectives of the Paris Agreement and minimize global climate change and its risks. Their stories should inspire all of us to contribute more energetically to climate action.
SDG Media Compact: Exclusive Interview with Rachel Kyte, Chief Executive Officer of Sustainable Energy for All
Ms. Rachel Kyte,
Chief Executive Officer of Sustainable Energy for All, and Special Representative of the UN Secretary-General for Sustainable Energy for All. Ms. Kyte was the World Bank Group Vice President and Special Envoy for Climate Change, leading the Bank Group’s efforts to campaign for the Paris Agreement.
The cost of renewable energy is low, and at times, less than fossil fuels. What are the barriers to switching to renewables?
Where current energy systems exist, they will need to be upgraded to be able to draw power from modern renewables and to exploit storage solutions that they require. The institutions and mindsets of current systems are still comfortable with the systems of the past, those that prioritized fossil fuels in centralized grid systems.
The revolution of renewable energy is not just that it’s clean, but that it can be delivered both through the grid as well as decentralized solutions, allowing it to reach those who have never enjoyed access to reliable and affordable energy before. Yet this change requires political leadership and policy certainty for the levels of investment needed, and we need that renewable investment now.
The recent Cooling for All report highlighted an issue many people didn’t speak of until recently. How does it relate to climate?
As the world warms and populations rapidly grow, particularly in the cities of the developing world, we risk creating ‘heat islands’ that could substantially increase energy demands as people seek cooling access for their own health and safety, as well as the safety of medical supplies, fresh food and safe work environments. At the same time, if we rely on today’s cooling technologies that use high hydroflourocarbons (HFCs) in air conditioning, we will exasperate climate impacts from a growing use of short-lived climate pollutants.
In policy terms, providing everyone with access to the sustainable cooling they need, is the opportunity at the intersections of the Sustainable Development Goals, Paris Agreement and the Kigali Amendment. In human terms, finding a way to provide hyper efficient pollutant free cooling for people, their vaccines and food is about making sure we leave no one behind. While the Paris Agreement reached almost universal ratification in record time, we now need member states to move with the same swiftness and determination to ratify the Montreal Protocol’s Kigali Amendment.
Can governments, businesses and communities that embrace clean energy solutions survive economically, and where do you see the greatest impact of green energy solutions?
The scientific evidence presented in the IPCC report means that all governments, through meeting their fundamental responsibilities in providing a duty of care to their citizens, need to ensure that aggressive and comprehensive policies are in place to speed energy transitions towards clean, affordable and reliable energy for all.
For business, being able to be on the leading edge of this transition means being positioned for profitability, success in attracting and retaining talent, and ensuring that inevitable regulation – and in some cases litigation – is a risk that is understood and well managed. All businesses must regard carbon as a toxin which needs to be avoided, mitigated and managed to not only support climate action, but help ensure their business is resilient to the ever-growing impacts of climate change.
Can we realistically meet the needs of the just under 1 billion people who don’t have regular access to electricity through renewable energy?
Yes. As an immediate step, we all have to be much more efficient in our use of energy. We can provide for many more needs with much less energy through technological innovation and business models. Renewable energy gives us a cost-effective way to meet the needs of those who have never had energy before to help them become economically productive.
By putting the needs of the last mile first, we can build decentralized, digitalized and decarbonized energy systems that meet everyone’s needs. This is not beyond human ingenuity – the cost is estimated at just over US$50 billion a year. Yet it requires political will and determination. When we consider that US$50 billion leaves the African continent through illegal financial flows, money laundering and tax evasion each year, we must work harder to ensure that the energy needs of these vulnerable populations – women, children, remote rural populations – can be met.
How can we support low-income countries when it comes to innovation and strengthening infrastructure that allow for modern technology approaches?
First, we need to support countries put in place robust policy frameworks and investment climates that will spur both domestic investment as well as attract international investment. Secondly, development finance, in partnership with these countries, has to be directed to meet the needs of the most vulnerable.
Our recent Energizing Finance report clearly shows that finance is still not reaching the top 20 countries with the largest electricity and clean cooking access gaps – dramatically slowing down progress to meet global energy goals and our promise to these populations.
Thirdly, we need specific initiatives that provide energy to the growing number of displaced people around the world.
Finally, the 3 billion that don’t have access to clean cooking deserve an urgent response from the international community at scale that connects industries around different fuel sources with new financial innovation that means the billions of women living on low incomes have a range of clean fuel choices, as opposed to the dangerous choice to cook a family meal while putting their health and the health of their children at risk.
