Overview

The impacts of global warming are already with us. Further deterioration is now unavoidable. Since the Paris Agreement of 2015, lack of political will, a failure to deliver on commitments, or plain obstruction have all but wasted the available time to act. The stakes over who will pay the price, financial or human, have been raised: climate action must address the issue of climate justice and reparations.

  1. The world cannot wait

    COP27 is the “number one litmus test” of how seriously the world takes the toll on countries that suffer most from climate change, according to the UN Secretary-General. November’s summit must finally make good on promises to deliver climate action that ensures a sustainable future for all

  2. Ideas into action

    At this mid-point to the 2030 deadline, it’s clear that action must ramp up massively if the SDGs are to be realized and climate catastrophe averted. Initiatives such as the UN SDSN Global Climate Hub can help get governments back on track

Future zero

  1. Walking the path ahead

    Humanity should survive the decades to come, but will it thrive? A lot depends on how many costs our leaders are willing to pay up front, and how many they will wait to have inflicted upon them

    Fred Carver
  2. Future settlements

    As the climate warms, and as behavior and practices shift to mitigate and adapt, what changes will there be to the nature and location of human settlements?

  3. Rethinking consumption

    We cannot hope to tackle the climate crisis without a fundamental shift in how, what, and why we consume

    Stefanie Hellweg, Andreas Frömelt, Livia Cabernard, Jonas Mehr, Rhythima Shinde
  4. A warmer world: are we ready?

    Even the most optimistic predictions show a significantly warmer planet by 2100. Rather than focusing on quick adaptive fixes, as many current plans do, countries must pursue climate-resilient development strategies that address the systemic nature of the climate crisis

  5. Mobility without carbon

    A net-zero and inclusive mobility future for all doesn’t depend on futuristic, as-yet-unknown transport solutions. We already have the necessary tools, knowledge, and resources, but must urgently deploy them in new, transformative ways

    Alice Yiu, Christopher Dekki
  6. Zero-carbon, climate-resilient cities

    As the world’s urban population rises dramatically this century, the sustainability of cities will be make or break for our survival. While the scale of the challenge is huge, many cities are showing how zero-carbon, climate-resilient urban centers are possible

Bridging gaps

  1. Leaving no one behind on climate action

    Systemic inequalities mean lower-income countries are often sidelined when nations gather to set climate policy. Giving communities who suffer most from climate change a meaningful seat at the negotiating table is essential if we’re to steer an inclusive course on climate action

    Anisha Nazareth, Dayoon Kim
  2. Stimulating innovation for net zero

    New technologies will play a vital role in achieving net zero. Getting them on stream and in widespread use fast enough to prevent climate catastrophe calls for bold and urgent action to unblock essential investment

    Anna Valero
  3. Engineering challenges: technological missing links in climate action

    As the IEA warns, most of the reductions in emissions needed to achieve net zero rely on technology that is not yet commercially mature. While tech will provide no magic bullet, its rapid development to scale up decarbonization is essential. What are the technological gaps we must focus on filling now?

  4. Enabling migration as adaptation

    As the climate warms, more people will be forced or will want to move, both within and between countries. How do we ensure that migration is supported, equitable, and beneficial for migrants and for sending and receiving communities?

    Julia Blocher, Kira Vinke
  5. How to curb negative international spillovers?

    Rich countries show no signs of decoupling their economies from the harmful environmental and social impacts they generate abroad. This must urgently change if we’re to achieve the SDGs and limit temperature rise, but requires bold international action

    Guillaume Lafortune, Eamon Thomas Drumm
  6. Trade’s role in climate action

    International trade can play a vital role in tackling climate change and achieving sustainable development. But it calls on governments to set aside national interests and open up access to environmental goods, services, and technologies for all countries

    Lucie Qian Xia
  7. Building for climate

    The construction industry accounts for more than a third of the world’s carbon emissions. The sector must urgently ramp up new methods to slash CO2 from the construction lifecycle if we’re to achieve net zero

    Karen Scrivener

Action now

  1. Masks off, gloves off

    Oil and gas companies turn record profits, while their fossil-fuelled emissions rapidly accelerate climate change. Tackling the problem means challenging these powerful economic interests and the political access it affords them

    Pascoe Sabido
  2. Wanted: data on pricing climate risks

    Private markets function on data – but the data to accurately price climate risks in investment decisions is sorely lacking. We must urgently fill this information void or private finance will fail to contribute to climate action

    Frédéric Blanc-Brude
  3. Climate-proofing to sustain peace

    Vulnerability to climate change is higher in many places suffering war, yet peacebuilding efforts often fail to consider climate impacts. In a warming world, where conflict and crisis persist, ensuring that efforts to sustain peace also support climate action must be a top priority

    Catherine Wong
  4. Protecting global public goods fairly

    How can you achieve an equitable balance for investment, responsibility, accountability, and authority for natural resources that function as a global public good? Can efforts to restore the Amazon rainforest provide an instructive example?
