Climate change and COP28
What needs to happen?
Fast-tracking the energy transition
The Paris Agreement necessitates an urgent phasing out of fossil fuels alongside a system-wide transition to renewable energy.

Policy
Dr Shivika Mittal is a Lead Modeller in the Grantham Institute鈥檚 Mitigation team 鈥� a group of interdisciplinary researchers informing policies on reducing greenhouse gas emissions.
Her work shows that current policies are insufficient for achieving the Paris Agreement.
鈥淓惫别苍 if we implement all our pledges, we鈥檙e still going to overshoot the 1.5掳C target. That's without taking climate impact into account. We'll miss it by even further if we do," she says.

鈥淭here鈥檚 a big gap between what countries are saying and the policies they鈥檙e implementing.鈥�
The impacts of climate change and our pathways for mitigating it are currently considered separately. Dr Mittal is figuring out how we can combine the two, so that countries can get a clearer sense of why it is important to act immediately.
鈥淭hese are not separate worlds. Climate impact and mitigation exist in the same world, and one affects the other,鈥� she says.
Dr Mittal also highlights that: 鈥淭here鈥檚 a big gap between what countries are saying and the policies they鈥檙e implementing. Even in the UK, we talk about net zero, but the government is relaxing its policy.鈥� According to her, this mismatch is a major issue which needs to be addressed at COP28.
鈥淭here needs to be a monitoring mechanism which checks whether government targets align with the policies they鈥檙e implementing to achieve those targets,鈥� she adds.
鈥淥nce you start overshooting 1.5掳C, you fall into this vicious cycle where delaying mitigation only makes stopping climate change more and more difficult,鈥� Dr Mittal warns.
Mitigating climate change and transitioning from fossil fuels requires significant investment in upgrading existing energy infrastructure to allow renewables to enter the market.
However, every country has a limited budget for achieving this.
As we delay climate action further, we make the impacts of climate change worse.
This demands more money to be spent on adaptation, aid, rebuilding efforts following extreme events, or re-escaping the poverty cycle after falling back into it.
This in turn drains the money set aside for mitigation, delaying action even further.
鈥淒elaying action by 10 or 20 years isn鈥檛 going to help us achieve 1.5掳C 鈥� we need strong policies now. We cannot go back if we cross a tipping point, so early action is vital in this COP.鈥�
The 1.5掳C target was strategically selected to help us evade the worst of climate change. Although current policies are insufficient for achieving this goal, Dr Mittal emphasises how critical it is that we continue doing our best regardless.
鈥淓very 0.1掳C we save takes us to a better place than if we did nothing. Each 0.1掳C means we鈥檙e saving a thousand lives. Or a whole country. This is well worth our time and effort. So, we need to look at it from that angle and not think that overshooting means there's no point,鈥� she says.
鈥淭hese are thresholds from a scientific point of view. From a human perspective, we all know a 1掳C world is significantly better than the 1.2掳C world we鈥檙e living in today. Maybe we鈥檙e not in a better situation, but at least it's still liveable for future generations.鈥�
Innovation
Fast-tracking the energy transition also requires technology. Alyssa Gilbert is the Director of Innovation at the Grantham Institute and leads Undaunted 鈥� 911今日黑料鈥檚 hub for climate change innovation.
鈥淲e cannot entirely rely on innovating our way out of climate change. Innovation is only a part of the solution,鈥� she says. 鈥淗aving said that, there is a role innovation can play at the implementation stage."

鈥淲e already have at least 50% of the technical solutions we need to stop climate change 鈥� we just need to implement them now.鈥�
According to Ms Gilbert, this necessitates innovative policies that can help roll out existing solutions, particularly relating to energy efficiency, renewable power and renewable power infrastructure, alongside innovative business models and pricing structures to distribute and adapt these technologies to diverse audiences and contexts.
Undaunted addresses exactly these challenges by bridging the gap between entrepreneurs and policymakers, fostering the scale-up of climate solutions, and developing the ecosystem and marketplace needed for climate startups to thrive.
鈥淲e do also need some brand-new innovations,鈥� she adds. 鈥淧articularly around areas where we don't have solutions like alternative materials, mechanisms for recycling critical rare earth metals, and battery technologies that don't rely on lithium.
鈥淗owever, we shouldn't wait for those, because we already have plenty that still needs to be implemented. Relying on innovation alone but ignoring the pathway to scale isn't the solution 鈥� we should do both.鈥�
Fixing climate finance
refers to funding used for activities that aim to mitigate or adapt to the impacts of climate change.
Mitigation and Adaptation
鈥淲hen we talk about climate finance in relation to international events like COP, it really comes down to how much financial support wealthier countries will give to enable the less wealthy parts of the world to take action on climate change,鈥� explains Ms Gilbert.
In her view, a major reason why climate finance needs 鈥榝ixing鈥� is because commitments to provide these funds are either too low, unreliable, or delayed. In addition, not everyone likes the existing mechanisms and institutions used for distributing this money.
The obligation to provide financial support is enshrined in the Paris Agreement, which promised to mobilise US$100 billion per year for developing countries by 2020 鈥� a figure determined through political negotiations and only partly based on scientific evidence of developing countries鈥� needs, which in fact run in the trillions.
This commitment, which has not been met, is set to be replaced by a rooted in science-based assessments of the demonstrated needs and priorities of developing nations.
Loss and Damage
Climate finance also includes discussions around compensating the countries most affected by climate change. However, this funding is predominantly delivered as loans rather than grants, exacerbating debt pressures and inequities across regions further.
鈥淥ne thing I know for sure is that the financial architecture needs reforming,鈥� says Dr Joyce Kimutai, a Research Associate with the Grantham Institute and a member of the team - which studies extreme events as they happen to understand the extent to which climate change has caused them.
鈥淭he funding that [vulnerable countries] should be getting should be in the form of grants and not loans, so that they can continue to develop their economies, sustainably.鈥�
鈥淔or developing countries, any climate finance that comes to them is in the form of high-interest loans,鈥� she explains. 鈥淭hey鈥檙e already having to dig deeper into their pockets to respond to extreme events, then on top, they must also ask for more loans that will likely escalate their debt burden.
鈥淩eforming the ways in which developing and vulnerable nations can acquire credit is crucial. The funding that they should be getting should be in the form of grants and not loans, so that they can continue to develop their economies, sustainably.鈥�
Ms Gilbert adds: 鈥淭here's a clear need for funding, but no one's really decided - who's giving how much?, when are they going to do it?, can they be relied upon to do it?, and how is it being transferred in a way that everybody's happy? These issues remain contentious and difficult.鈥�
Private finance
While public finance from developed to developing countries will be the main source of climate finance funds, this alone will be insufficient to meet the needs and priorities of developing countries. Private finance has to be mobilised as well.
鈥淭he capital investment needed to achieve 1.5掳C is huge, so private finance is very important,鈥� Dr Mittal says. 鈥淥nly thing is, we need to figure out how to minimise the risks attached to investing in developing countries.鈥�
She suggests having policies which protect private investors from credit risks, political instabilities, and currency fluctuations, while also having ways of monitoring, auditing and reporting the efficacy of investments, so funders can be certain that their investment is working.
鈥淭he capital investment needed to achieve 1.5掳C is huge, so private finance is very important. Only thing is, we need to figure out how to minimise the risks attached to investing in developing countries.鈥�
Technology can pose risks too. 鈥淭he World Bank and other NGOs have implemented several solar plants which failed because the local population wasn鈥檛 equipped to operate the technology,鈥� Dr Mittal warns.
Ms Gilbert adds: 鈥淥ffering credible and well-supported upskilling programmes to create the necessary workforce that can deliver the larger-scale implementation of the solutions we already have is crucial.鈥�
By removing such risks, developing countries can attract more private investment.
Focussing on people, nature, lives and livelihoods
As well as being fast, the energy transition must be fair.
Historical responsibility for climate change
Twenty-three rich, developed countries that account for just 12% of the global population are responsible for half of all historical carbon dioxide emissions from fossil fuels and industry.
However, the worst impacts of climate change are felt disproportionately by developing nations that had little to do with causing it.

Just Transition
A net zero transition will bring many societal benefits, such as environmental protection, improved health, and economic growth. However, climate policies can also result in social injustices. For instance, communities that are dependent on carbon-intensive activities or fossil fuel production for their livelihoods will lose a substantial portion of their incomes.
Dr Ivana Popovic is a Research Associate at 911今日黑料鈥檚 Centre for Climate Finance and Investment. Her work focusses on the importance of ensuring a just transition.
鈥淎 green transition will create more jobs than it would take. Nevertheless, these new jobs might not necessarily emerge in the same locations as the old ones, potentially leading to involuntary migrations,鈥� she says.
Low-income groups and communities may also lack the resources to adjust to the negative impacts that a green transition could bring.
鈥淎 just transition is about considering social injustices alongside environmental concerns by including all social actors into decision-making processes and understanding the full scope of a green transition 鈥� environmental, economic and social.鈥�
The observed fairness of a net zero transition significantly influences public support for it, so ignoring just transition considerations could lead to climate action either failing or being delayed. This could also create economic and financial risks.
However, Dr Popovic notes that: 鈥淛ust transition considerations are not to be used as an excuse or justification for climate inaction. We can鈥檛 keep delaying climate action because it also creates certain social injustices.
鈥淭he goal is to address urgent environmental issues while simultaneously acknowledging the existence of these adverse socioeconomic impacts and seeking solutions for them in a way that benefits everyone.鈥�
Phasing down vs phasing out
A just transition looks at the impact that net zero will have on communities to identify where additional, proactive policy support may be required to minimise any negative impacts.
鈥淚f we close a coal mine, let鈥檚 invest at the same time in the green economy of that particular community to help them overcome their difficulties in an environmentally sustainable way,鈥� Dr Popovic says.
Similarly, Dr Mittal argues that phasing out fossil fuels is necessary for achieving net zero or 1.5掳C, but she says: 鈥�We shouldn鈥檛 put all the burden on developing nations. Countries with historical responsibility for climate change must pay to help others to phase out.
鈥淐limate change is not our only problem. Developing countries also face several other challenges like poverty. So, we need a just transition that tackles all these issues simultaneously, otherwise we could end up creating a set of new problems.鈥�
Dr Kimutai adds: 鈥淲e have to transform every bit of our lives, behaviours, food systems, infrastructure, and so on. Every part of every system needs to become sustainable.
鈥淭he problem is we're taking too long to transition by allowing ourselves to phase down,鈥� she says. 鈥淔or us to limit warming to 1.5掳C, we need a deep, rapid and sustained cutting of emissions.鈥�
Biodiversity
Dr Caroline Howe is a Senior Lecturer in Environmental Social Science at 911今日黑料鈥檚 Centre for Environmental Policy, teaching its longest-running MSc programme 鈥� Environmental Technology. Her interdisciplinary research explores the shared relationship between people and nature, and how this influences policies around sustainable development and environmental conservation.
Dr Caroline Howe
Dr Caroline Howe
is currently declining at an unprecedented rate, with human activity pushing of plants and animals towards extinction 鈥� the largest loss of life since the dinosaurs. Extinction is now a real possibility for many seemingly resilient species including .
This biodiversity loss ; over 80% of our food comes from plants and roughly three billion people worldwide depend on fish for their protein. Likewise, 80% of rural populations in developing countries rely on traditional plant鈥恇ased medicines for basic healthcare.
Despite this, 鈥渂iodiversity is often considered the poor cousin of climate change 鈥� there's a lot more money invested in climate,鈥� highlights Dr Howe. She adds that: 鈥淲e cannot tackle one and ignore the other. If we lose biodiversity, we will fail on climate.
鈥淐limate change is typically more visible to us than biodiversity loss because billions of people live in urbanised societies today, where they are removed from the fact that biodiversity is essential. It is therefore vital that we recreate our bond with nature.鈥�
鈥淲e cannot tackle one and ignore the other. If we lose biodiversity, we will fail on climate.鈥�
Environmental education and improved access to green spaces can help with this. There are also international goals - such as the Global Biodiversity Framework鈥檚 , which aims to protect 30% of land and seas by 2030, and the UN's (SDGs).
Dr Howe acknowledges that these are goals that people can get behind. 鈥淚'm happy that at the international scale we can come to some agreement,鈥� she says. However, for her, 鈥淭he question is, how will it be implemented?鈥�
She says: 鈥淭echnically, there's a lot of land and sea that you could protect quite easily as it's got nothing left since we've destroyed it already - so, you're not necessarily achieving anything.
鈥淭he most biodiverse areas are also areas with the highest levels of poverty and communities that rely heavily on land for natural resources. Such interventions should therefore be implemented carefully by considering that sometimes the best people to look after those areas are the people that have always lived there and know how to use it.
鈥淪o, the 30 by 30 [framework] requires very careful consideration of where that 30% is and who may be influenced by, or affected by protecting that 30%.鈥�
Nature-based solutions
Biodiversity and climate change are inextricably linked; destroying nature is a major driver of climate change, while climate change is among the leading causes of nature loss.
Yet, they are often considered separately by most actors, including policymakers, financial institutions, and even the scientific community.
Dr Popovic, who also works on nature-related finance and investments, argues that this shouldn't be the case. She is among the growing voices calling for an integrated approach to nature and climate.
鈥淣ature lags behind climate in some sense because, besides the scientific community, our understanding of climate change surpasses our knowledge of nature loss,鈥� she says.
Biodiversity sequesters carbon pollution, cleans our air and water, protects us from the impacts of climate change, pollinates our crops and boosts our wellbeing. Yet, the significant potential of nature-based solutions is undervalued, untapped and under-resourced.
Financial flows to protect and enrich biodiversity are still on the margins of global finance, with estimates pointing to a large .
鈥�We鈥檙e still searching for ways to understand nature and invest in it to generate financial profit, alongside the evident environmental benefits,鈥� Dr Popovic says.
鈥淣ature-based solutions can provide sustainable ways of adapting to climate change 鈥� especially for the most vulnerable communities.鈥�
Nature-based solutions can also be a cost-effective way to mitigate climate change.
鈥淧olicymakers should figure out which solutions work best and carry the least risk. We shouldn鈥檛 over-rely on technology that鈥檚 still unavailable 鈥� nature-based solutions are proven to work and don鈥檛 require as much capital,鈥� Dr Mittal says.
Dr Kimuati agrees that, 鈥淣ature-based solutions can provide sustainable ways of adapting to climate change 鈥� especially for the most vulnerable communities.鈥�
At the same time, she adds that: 鈥淎s populations grow, we shouldn't put too much burden on land to be our solution to the climate crisis on top of all the ecosystem services it provides us.
鈥淲e have to cut our emissions at the same time and not think that we've found a solution in nature, so let's continue business as usual.鈥�
Full inclusivity
Inclusivity and Sustainability
Dr Howe has been working on understanding the inequities and injustices involved in sustainable development and environmental conservation.
She warns that you can come up with a perfect technical solution for climate change, but: 鈥淯nless it鈥檚 socially acceptable and doesn鈥檛 cause injustices or inequities elsewhere, it's not going to work.鈥�
One of her previous projects looked into the implementation of the UN's SDGs. 鈥淚f you look at them broadly, the SDGs look great,鈥� she says. 鈥淗owever, they鈥檙e very top-down and fail to take into consideration the nuanced cultural relationships many communities have with nature.鈥�
Dr Howe adds: 鈥淵ou have no understanding of what ecosystem services are unless you talk to people and try to understand what they need, want and value. This is crucial for the successful implementation of climate action.鈥�
An example of this is locally-led climate action. Dr Kimutai explains: "You want the locals to propose adaptation strategies that they think can work for them. That way, you鈥檙e welcoming them to the table to discuss with you.鈥�
鈥淔irst, they understand the problem; then, they鈥檙e a part of the solution,鈥� she adds.
鈥淐o-producing solutions in this way encourages ownership by the community, as opposed to prescribing solutions to them that they will likely not understand.鈥�
Equity
Dr Howe believes that loss and damage funding will be fundamental for reducing inequities across regions disproportionately feeling the worst impacts of climate change. She therefore believes it is important to ensure its proper delivery.
鈥淧revious reforestation schemes have claimed to compensate locals for relocating them to replant trees,鈥� she says. 鈥淭his sounds utopic in principle, but a lot of the time, the money never reaches the communities. Instead, it ends up with corrupt officials, businesses or the people with power.
鈥淭his is where the finance for any mitigation and adaptation has to learn 鈥� we know why these things fail, so we must learn and ensure it doesn't happen again.鈥�
Dr Howe also envisions an energy transition where everybody feels the benefits of clean energy and countries help one another.
鈥淢uch of the UK鈥檚 electricity currently comes from renewables, but this isn鈥檛 reflected in our bills. A just transition must ensure that this trickles down and the people using this energy can feel the cost benefit 鈥� if they do, they'll buy into it more as well.鈥�
Similarly, she calls for globally-shared expertise. 鈥淪upporting other countries that receive more sunlight than us to develop their own solar technology, for instance, can enable them to become independent,鈥� she says.
鈥淣obody should be importing energy in any country. They should be using their own, locally-generated sustainable energy that is readily accessible and works best for that particular region.鈥�
Tailored solutions
The issues that people face, their understanding of these issues, and how they respond to them is all context-specific. Solutions must equally reflect that.
Dr Kimutai advocates for science led by countries in the Global South - a term used to describe nations which are often known as developing countries - to provide evidence-based solutions for their challenges. 鈥淎frican solutions for African problems are key because we have the understanding of the region,鈥� she explains.
鈥淚mporting solutions that work in the Global North [or developed countries] and assuming they鈥檒l work in the Global South is problematic because it doesn鈥檛 necessarily work that way.鈥�
"Solutions should be tailored to each country鈥檚 unique challenges and resonate with the local landscapes, cultures, and communities they鈥檙e intended to serve.鈥�
Ms Gilbert echoes this appreciation for tailored solutions. She says: 鈥淚t is really exciting to see the different ideas produced in different parts of the world, because they're all context relevant. People are often tackling different priorities depending on the challenges they see around them, which manifests very differently.
鈥淯niversities are engines of innovation and education that can foster this. We have the space to be creative, try things and fail, and to provide ideas. We can also convene diverse groups of innovators worldwide to exchange ideas and expertise.鈥�
Hopes for COP28
Dr Howe stresses that climate action at this year's COP needs to be "hard and fast". She says: 鈥淲e have to make sure we act now because we do only have until 2030, if that. So, there has to be a lot more action than previous COPs."
鈥淭here also needs to be an incentive, and therefore, a financial disincentive or punishment for countries that U-turn on their commitments,鈥� she adds. 鈥淚n the UK, we've recently had quite a lot of U-turns on net zero policies. I don't think a leading country should be doing that. We have the technology, the people to understand it, and a willing audience. We should be leading the way.鈥�
Meanwhile, Dr Kimutai ends her thoughts on a positive note: 鈥淲e're not doing great. We need to do better. But I'm still very optimistic that we can [do better].
鈥淓very reduction of greenhouse gas emissions matters. And every adaptation strategy that鈥檚 being implemented matters. However small the teeth. Whether it is you switching off the lights before going to work, or using your water sustainably in the house, it really matters. There's still room for humanity to say that solutions are within us and we can provide them.鈥�
