Climate Change


Organisations and researchers supporting the Charter

The 1.5 Degree Charter calls for a fresh approach to climate finance and justice in the 2020s.  To keep global heating below 1.5˚C this century richer countries will need to pay reparations to poorer countries; with the amounts reflecting the former’s responsibility for the crisis and the latter’s vulnerability to it.

This is about finding solutions to the climate crisis that embody fairness and build trust. Lower income countries did not create this problem, yet they are already paying for it with their livelihoods and increasingly their lives. It’s up to those who have contributed the most to the problem to address that injustice and build trust going forward. Solving the climate crisis means acknowledging the damage already caused and making new alternative plans and choices to reverse that tide.  

The global South has been a small part of the problem so far, but it’s a huge part of the solution. We need to demonstrate that the safety and security of its people are a priority. As with the pandemic, none of us is safe until we are all safe. Similarly, no country can fully protect against the impacts of climate change unless we are all protected against them. 

Stabilizing our climate requires emissions to drop to net zero. But building a prosperous and resilient world will require more than that, it will require increasing the power of the income poor and making investments to protect those who are already suffering the most through no fault of their own.

The science is clear - going beyond 1.5°C will increase human misery around the world and put a huge financial burden on all of us. Our Charter calls on the governments of the world to invest in dealing with climate change now, which will not only increase people’s health and well-being now but will save trillions of dollars.

We call on everyone that cares about our planet to sign our Charter to show that citizens of the world want Governments, corporations and the wealthy to invest in dealing with climate change. The burden of saving our planet must fall on the wealthiest in our global society as they have contributed most to the problem through excessive consumption.

Our research shows how earlier action to improve financing conditions could have a significant impact on the speed and timing of the transition to renewable energy in lower- and middle-income countries which, in turn, will significantly help to protect our planet.

We don’t believe it is fair that regions where people are already losing their lives and livelihoods because of the severe impacts of climate change also have to pay a high cost of finance to switch to renewables. Radical changes in finance frameworks are needed to better allocate capital to the regions that most need it. We should take the opportunity to reframe international market finance, where lower cost of capital for developing economies would allow for low-carbon development at a more internationally equitable cost. The sooner we act the better.

Global warming above 1.5C markedly increases the risk of crossing climate tipping points which will do greatest harm to the world’s poorest. Multiple abrupt climate changes occur between 1.5 and 2C global warming in IPCC climate model runs. Going to 2C warming risks a collapse of the West Antarctic ice sheet that would accelerate sea-level rise and threaten low-lying islands and coastlines such as Bangladesh. It would also degrade essentially all tropical coral reefs on which many depend for their livelihoods.

Going from 1.5C to 2C warming would put hundreds of millions of people – mostly in sub-Saharan Africa and the Indian subcontinent – outside of the climate ‘niche’ that supports high human population densities today and has done in the past. It would also greatly increase their exposure to life-threatening hot and humid climate extremes.

The concept of loss and damage from human induced climate change is closely connected to whether world leaders keep their commitment to remaining below 1.5 Degrees Centigrade or not. For every fraction of a Degree that the world goes above that threshold, the associated loss and damage will be exponentially worse and will fall mainly on the world's poorest communities in the poorest countries.

We already live in a climate-changed world of 1.2 degrees higher temperature relative to pre-industrial levels. But with no ambitious mitigation around, adaptation finance to support the most impacted communities is woefully poor.  Against this, it is ironic that world military spending witnessed a hike, even in 2020, hitting the two trillion-dollar mark.

The G7's announcements around digital taxation point to an appetite for innovation in finance that now urgently needs to be applied to the task of delivering climate justice as we approach COP26. As COP president, the UK government currently talks about the objective of coming good on past commitments of $100 billion a year. But these are (broken) promises that were made 12 years ago in Copenhagen. In the time that's elapsed, we've seen the impacts of climate breakdown incur costs related to loss and damage alone in excess of $150 billion a year.

With rising global temperatures, the costs of climate breakdown are escalating and will continue to do so. The burden of these costs will fall hardest on those living on the frontlines of climate breakdown - those whose lives are already the most precarious and who are least responsible for creating climate change. It will also fall on our children, and on our children's children unless, collectively, we're able to achieve what we're setting out to achieve with this 1.5C charter - a paradigm shift in how we perceive our collective responsibility to steer a path towards a sustainable future.
