How will our climate budget look post-NAP2050?

publications

Two facts related to climate-relevant funding in Bangladesh fascinate me. First, between 2015-16 and 2022-23 fiscal years, Bangladesh allocated 7.26-8.1 percent of its annual national budget as climate budget, which is 0.7-0.8 percent of the national GDP. Second, 18 years ago, the National Adaptation Programme of Action (NAPA) estimated to invest $73.5 million in climate change adaptation over the following few years. But such strategic planning magnified manyfold in October 2022, when the government approved the National Adaptation Plan, 2023-2050 (NAP2050), targeting to spend $230 billion over the next three decades.

Since the government is now preparing its annual national budget for FY2023-24, what changes can we expect to see in the climate-relevant allocations, post-NAP2050?

I think we can expect three specific achievable changes in the forthcoming climate budget. First, in the current fiscal year, with a total climate budget of Tk 30,500 crore, the three ministries or divisions (out of 25) with the highest climate allocations are Ministry of Agriculture (Tk 8,667 crore), Local Government Division (Tk 3,768 crore), and Ministry of Water Resources (Tk 3,484 crore). In addition, the climate budget also shows allocations against six thematic areas of the Bangladesh Climate Change Strategy and Action Plan, 2009. Here, the highest allocation is made to food security, social protection, and health (41.87 percent), followed by infrastructure (27.78 percent), mitigation and low-carbon development (13.36 percent), comprehensive disaster management (7.21 percent), capacity-building and institutional strengthening (6.71 percent), and research and knowledge management (3.07 percent). These thematic allocations broadly match the ministerial allocations.

In the FY2023-24 budget, we also need to see the geographical distribution of the climate allocations. The NAP2050 contains the latest climate vulnerability maps of Bangladesh considering a wide range of shocks (e.g. cyclones and floods) and stresses (e.g. rise of sea level and salinity intrusion), prepared by the Center for Environmental and Geographic Information Services (CEGIS). The CEGIS can help the Finance Division to prepare maps combining climate fund allocations against the degree of climate vulnerability. These maps should carry information down to the upazila level, if union-level information is not available for now. We indeed need to know how much money is going to Dhaka and how much to Dacope (Khulna), Derai (Sunamganj) or Dimla (Nilphamari).

Second, in the forthcoming climate budget, a separate section should be added on investments to be made in nature-based solutions (NbS) to tackle climate change. Here, NbS means to protect, restore, create, and manage aquatic and terrestrial ecosystems to adapt to climate change impacts as well as reduce carbon dioxide in the air, while increasing the local biodiversity. Focusing on NbS has two specific rationales. First, the NAP2050 has already included NbS as one of its six main goals. Second, unlike climate finance, our conservation finance is poorly defined and is essentially made of project-based, short-term investments.

The Ministry of Environment, Forest and Climate Change and its concerned departments are showing low interest in sustainable conservation financing. Therefore, we are not going to see much progress in establishing new funds as outlined in the Ecologically Critical Area Management Rules, 2016, the Protected Area Management Rules, 2017, and the Bangladesh Biodiversity Act, 2017 any time soon. But the Kunming-Montreal Global Biodiversity Framework, agreed upon by 188 countries in December 2022 in a global biodiversity meeting in Montreal, Canada, emphasises conservation finance to minimise the current annual gap of $700 billion.

By incorporating NbS allocations into Bangladesh’s climate budget, we can essentially bring together financing of two biggest crises of our times: climate emergency and biodiversity loss. The environment ministry should work with the finance authorities to develop a tool to collate investments in NbS by different government agencies every year. Our experience of preparing climate budgets should be useful here.

Over the last two years, Bangladesh has developed two climate-related investment plans: the draft Mujib Climate Prosperity Plan 2030 (MCPP2030) and the NAP2050. The climate budget for FY24 should track how many of these financial targets have been achieved or have received commitments from donors and development partners. If we look into the NAP2050, about 72.5 percent of the $230 billion fund has to be invested by 2040. This means the country needs to triple its current yearly investment, which now stands just above $3 billion.

In 2016, with FAO and USAID, the environment ministry prepared the Bangladesh Country Investment Plan for Environment, Forestry and Climate Change (EFCC-CIP). This CIP was supposed to be accompanied by a monitoring mechanism to track investments in these sectors until 2021, but it didn’t work out. Based on past experience, the ministry and FAO can work with the finance authorities to develop a monitoring and reporting tool to track investments to implement the NAP2050.

The NAP2050 is an ambitious plan with 113 priority actions in crucial sectors ranging from water, disaster management, agriculture, nature conservation and urban, to policy, institution, capacity-building and research. If the NAP2050 can’t make us rethink the way we prepare our climate budget, that will be a missed opportunity.

Climate visas could give victims of natural disasters safe route to UK, says thinktank

publications

Report also suggests migration could help ensure UK has necessary skills to meet government’s 2050 net zero target

New climate visas should be created to allow victims of natural disasters to come to the UK, and to bring in skilled workers needed for the transition to net zero, a Conservative thinktank has argued.

Onward, whose co-founder Will Tanner recently became Rishi Sunak’s deputy chief of staff, is urging the government to prepare for the likely increase in global migration as a result of the climate crisis.

The authors of the report call for the government to prioritise financial support for climate adaptation in developing countries, but also to open up new legal migration routes.

“We cannot allow climate-related migration to become the defining crisis of the 21st century. The government needs to act now to build climate resilience in the most vulnerable regions on the planet and open up safe and legal visa routes for those fleeing environmental disasters,” said the report’s co-author, Ted Christie-Miller.

Despite the hardline rhetoric on the illegal immigration bill by the home secretary, Suella Braverman, the authors suggest that welcoming a limited number of climate refugees would be consistent with the government’s approach.

The United Nations high commissioner for Refugees (UNHCR) has reported that an average of 21.5 million people were forcibly displaced each year by sudden onset extreme weather events between 2008 and 2016.

Citing the UK’s recent acceptance of thousands of Ukrainian refugees and Hongkongers through bespoke visa routes, the report calls for the introduction of a natural disaster visa scheme.

With major floods and droughts already becoming more prevalent as a result of global heating, the authors suggest such a route could allow for a limited number of people displaced by climate events to flee to the UK.

These refugees could be permitted to stay temporarily in the UK to earn money to rebuild their lives – or potentially to remain permanently. The report does not specify how many such visas could feasibly be issued.

Polling carried out for the thinktank suggests such a measure might find only limited support among the public, however: 29% of people agreed the UK has a moral obligation to host people displaced by the climate crisis, against 41% who did not. Among 2019 Conservative voters, support was just 21%, with 55% against.

Separately, Onward suggests migration could form part of the answer to ensuring the UK has the skills necessary to meet the government’s target of hitting net zero carbon emissions by 2050.

The report recommends a new environmental resilience visa scheme, which would involve the UK establishing partnerships with climate-vulnerable countries.

The authors suggest that under such a scheme, the UK would help to fund training in skills including “clean energy, construction, and disaster preparedness”, and could then allow some of those trained under the scheme to come and work temporarily in the UK.

Alex Chapman, senior researcher at the New Economics Foundation (Nef), agreed that the UK has a “profound moral responsibility” to support climate refugees whose predicament was ultimately set in train by emissions from developed countries over decades.

But he said bringing in workers from developing countries was not the right solution to plugging green skills gaps.

“A better approach would involve a wholesale rethink and expansion of the UK’s own upskilling system, which has been left broken and neglected. Over the course of the 20th century the UK established one of the strongest upskilling systems in the world, but successive reforms and funding cuts have seen the rate of adult participation in education crash, and our national productivity stall.”

A NEF report suggested that something between 4.5m and 8.5m cumulative years of full-time training were needed to bring the UK’s workforce up to the level needed to shift the economy to net zero.

But Chapman suggested that could be achievable by 2030, if adult participation in training returned to levels last seen in 2001, before funding cuts.

Time running out to defuse climate “time bomb”

publications

“If there is one key takeaway from this synthesis report – for nations, businesses, investors, and every individual who contributes to climate change – it is this: we must move from climate procrastination to climate activation. And we must do it today.” – UNEP Executive Director Inger Andersen

Humanity has the money and technology it needs to slash its greenhouse gas emissions but must act now to avert a full-blown climate catastrophe, warns a new report from the Intergovernmental Panel on Climate Change (IPCC), a body of leading climate scientists convened by the United Nations.

The Climate Change 2023: Synthesis Report is the final instalment of the IPCC’s Sixth Assessment Report and condenses nearly a decade of climate science into a 37-page document.

It said the world is already 1.1°C warmer than it was in pre-industrial times, and that “deep, rapid and sustained mitigation and adaptation actions” are needed this decade in order to stave off the worst of climate change.

The report lays out the devastating effects of a world in the grips of a full-blown climate crisis, including extreme heat, torrential rains, hunger and water shortages. This pain would be felt by the most vulnerable, it warned.

The report is expected to guide negotiations at the COP28 climate conference in Dubai later this year and at the Global Stocktake, where countries will review progress towards the Paris Agreement goals.

It is, in the words of the United Nations Secretary-General António Guterres, “a how-to guide to defuse the climate time-bomb; a survival guide for humanity.”

While it painted a dire picture of inaction, the report said the world has the solutions it needs to reduce greenhouse gas emissions and adapt to a changing climate. Many are already being implemented, although not at the scale required, it says.

Systemic change needs to happen across all sectors of the economy, the report says. That’s especially true of the energy industry, which will need to dramatically scale back its reliance on fossil fuels while using carbon capture and storage for emissions that are unavoidable.

Wind, solar and small-scale hydropower plants can increase energy reliability and reduce vulnerabilities to climate change, the report makes clear. The transport sector needs to embrace sustainable biofuels and low-emissions hydrogen, although cost-reductions will be needed. Electric cars powered by low-emission electricity can help reduce emissions, while advances in battery technology could help facilitate electrification of trains and heavy-duty trucks.

The report also called on cities to weave cycling and walking into their development plans and ensure that buildings are constructed and retrofitted in a way that reduces energy consumption.

“As the report lays out, there are multiple options for policymakers to tackle the crisis,” says Maarten Kappelle, Head of Scientific Thematic Assessments at the UN Environment Programme (UNEP). “Climate-resilient development, such as improving access to clean energy and technologies, low-carbon electrification and public transport is vital.”

The IPCC report also highlights the fact that maintaining the resilience of biodiversity and ecosystem services at a global scale depends on effective and equitable conservation of approximately 30 per cent to 50 per cent of Earth’s land, freshwater and ocean areas.

Finance will be key to this, but right now, the report says, “finance flows fall short of the levels needed to meet climate goals across all sectors and regions.”

The report also highlights the importance of safeguarding developing-world communities grappling with the fallout from the climate crisis, including floods, droughts and rising seas.

“Climate justice is crucial because those who have contributed least to climate change are being disproportionately affected,” says Aditi Mukherji, one of the 93 authors of the synthesis report.

While the report didn’t contain any revelations, it cast a spotlight on the pressing nature of the climate crisis. In order to keep the global temperature rise to 1.5°C or less, the most ambitious goal of the Paris climate change agreement, the world will need to cut its emissions of planet-warming gasses by 45 per cent by decade’s end.

“This report is pretty much as expected,” says Kappelle. “We know that we are running out of time to achieve the 1.5°C goal, and this report makes it clear how much we need to do to have a chance of getting close to that target.”

The IPCC is the leading authority on the science of climate change, and its reports are used as roadmaps by governments to reduce emissions and tackle the climate crisis.

The summary report can be seen as a guide for the next decade, consolidating the conclusions of the six documents published by the IPCC since 2015. With the next IPCC report not due until 2030, this is seen as the last chance to galvanize action on climate change.

“The report highlights the fact that political commitment and international cooperation is key,” Kappelle says. “No one sector or country can do this alone. There needs to be real cooperation at every level.”

It was a sentiment echoed by IPCC Chairman Hoesung Lee.
“Transformational changes are more likely to succeed where there is trust, where everyone works together to prioritise risk reduction, and where benefits and burdens are shared equitably.”

Climate-related disasters: 9.4m displaced in seven years

publications

Over a thousand lives lost, says study

At least 1,053 people were killed and 9.4 million more displaced internally in different climate-related disasters in 58 districts in seven years from 2014, says a recent study.

During the period, the country suffered economic losses of $4,120 million due to the disasters, including monsoon flood, flash flood, river erosion, cyclone, storm surge and landslide, found the study.

The country received only $104 million in humanitarian aid in those seven years following 15 major disasters, the study report said, adding that 42 million people were affected.

Analysing the data of all major natural disasters from 2014 to 2020, Start Fund Bangladesh (SFB), a civil society-managed network of 45 NGOs working in Bangladesh since 2017, conducted the study.

The SFB is going to unveil the report titled “Multivariate Analysis of Climatic Disasters, Financial Flow Analysis, and Analysis of Household Economic Status in Flood-Prone Districts” at a city hotel today.

The disaster management ministry assisted SFB in carrying out the study, which also projected how many people may be affected by different disasters and also prepared a map that shows the most disaster-prone areas.

“People living in disaster-prone areas are exposed to different natural disasters in various ways. Our study will help the government officials and aid workers have a clear idea about how many people could be impacted following a certain disaster and they would be able to take measures accordingly,” said Shofiul Alam, programme coordinator of Start Network.

Analysing the data of disasters that took place in the seven years, the study estimates that 12.10 million people belonging to 2.71 million households could potentially be affected each year by different climate-induced disasters, including monsoon flood, flash flood, river erosion, cyclone, storm surge and landslide,

The study has also taken into consideration other hazards such as nor’wester, cold wave, and hailstorm.

It also assesses that at least 18.33 million people may get exposed to climate-related hazards in 64 districts a year from 2021 to 2025. Around 66 percent of them would be affected by natural disasters .

It anticipates that the minimum economic loss would be $337.94 million in the same period.

According to the study, four northern districts — Kurigram, Gaibandha, Sirajganj and Jamalpur — are very prone to flood and river erosion, while four southern districts — Satkhira, Khulna, Barguna and Patuakhali — are at high risk of being hit by cyclone and storm surge. Besides, 27 other districts are exposed to disasters.

SFB has collected data for the study from multiple sources, including Bangladesh Agricultural Research Council, Multi Hazard Risk and Vulnerability Assessment Modeling and Mapping, National Disaster Response Coordination Centre, Centre for Environmental and Geographic Information Services, Forecast-based Warning, Analysis and Response Network, Needs Assessment Working Group, and Network for Information, Response and Preparedness Activities on Disaster.

The Delta Blues: Why Climate Change Adaptation is Crucial in the World’s Deltas

publications

Deltas are biodiversity hotspots that drive economic development and house thriving cities, yet they are particularly vulnerable to climate change. They require urgent adaptation measures to prevent losses that could stifle entire economies.

With fertile soils and some of the planet’s richest biodiversity, deltas generally belong to the world’s most densely populated areas. Trade and agricultural production have long flourished in these hubs of intense human and economic activity.

Deltas are climate hotspots where people, food production, wildlife and economic development meet the impacts of climate change – yet despite their indisputable value, climate adaptation in deltas does not receive the interest and funding it… CLICK TO TWEET

“In the race to adapt to climate change, deltas currently stand at the starting line. A lot of work must be undertaken to address adaptation in deltas, and we have to begin by understanding just how valuable these environments are as biodiversity hotspots and engines of economic growth, and just how gravely threatened they are by climate risks,” said Patrick Verkooijen, CEO of the Global Center on Adaptation (GCA).

In 2021, GCA launched a report that explores best practices in adaptation and resilience through inspiring case studies in selected delta countries. “Living with water: climate adaptation in the world’s deltas” aims to push delta adaptation efforts up the political agenda while presenting scalable and replicable adaptation best practices.

The report highlights that today, 500 million people live in delta and coastal urban regions, a figure expected to rise by 50 percent by 2050. Deltas are drivers of economic growth, and many, have a higher GDP per capita than the economies that host them. The Mekong Delta, for instance, is home to 20 million people and supports approximately a quarter of Vietnam’s GDP.

Vibrant cities and thriving agricultural and industrial centers exist along the world’s deltas. Europe’s largest seaport is located in the cosmopolitan delta city of Rotterdam. The biodiversity-rich Fraser delta has made the bustling city of Vancouver a major Canadian trade center. And the world’s largest delta, the Ganges-Brahmaputra-Meghna delta shared by India and Bangladesh, is home to nearly 200 million people and a major agriculture center with, amongst other, intense paddy cultivation.

What are deltas?

Deltas form at the mouths of rivers, where they deposit sediment and merge with another body of water such as the ocean. Deltas are nutrient-rich wetland habitats, and like most wetlands, they host diverse ecosystems and act as natural buffers for extreme weather events, such as storms, hurricanes and cyclones. They also filter water that flows downstream, reducing the impact of river pollution.

A ticking time bomb

Because climate change will be primarily expressed through water, delta regions are especially vulnerable to its effects.

report by the Intergovernmental Panel on Climate Change (IPCC) asserts with “high confidence” that even if the world were to reduce greenhouse gas emissions and lower global temperatures, deltas will be confronted with “high to very high risks” from rising sea levels in the future.

Sea levels are expected to rise by 0.5 meters by 2050 and over a meter by 2100. These projections place large parts of many deltas at risk of submergence. Indeed, experts predict that by 2050, seventeen percent of Bangladesh will be submerged, triggering the displacement of an estimated 20 million people. Saline intrusion is already threatening the soils, water supply and food security of many vulnerable populations in deltas.

Without urgent adaptation measures, the losses in some delta regions could stifle entire economies. Damage to infrastructure, crop production and fishing could reduce the GDP per capita by 19.5 percent in Bangladesh and by 9 percent in the Volta delta in Ghana. Food insecurity and the loss of livelihoods would be severe.

While many delta regions lack integrated climate adaptation plans, the nature of deltas provides opportunities for progress and innovative solutions.

In its flagship report Adapt Now, GCA proposes three ‘revolutions’ to accelerate adaptation that apply to deltas: understanding, planning and finance.

The complex issue of adaptation in deltas must be understood and viewed through a systems lens to address social, hydrological and economic interdependencies. Long-term, locally-led adaptation and investment plans must be developed and supported by political commitment. And finally, an increased level of financial resources must be mobilized, targeting the most vulnerable delta communities and taking advantage of the opportunity provided by Covid-19 economic recovery plans.

This integrated approach is being promoted by WWF’s Resilient Asian Deltas (RAD) Initiative, in collaboration with GCA, in Asia’s six biggest deltas. The initiative aims to improve the understanding of deltas and the processes that maintain them while catalyzing action at scale. Nature-based solutions case studies and real-world climate financing options are being developed, and a community of practice to bring together delta practitioners from across the region is being established.

“Adapting to climate change is a continuous process that takes time and resources and needs to be embedded in a long-term vision and strategy,” said Joep Verhagen, Program Lead of GCA’s Water and Urban Team. He noted that the implementation of several flood defense and climate adaptation plans in the Netherlands, such as the Delta Plan, is a continuous process spanning decades and is supported by long-term budget allocations.

Minimizing the threat of climate change and accelerating adaptation in delta regions is challenging but certainly possible. The Dutch approach of living with water, which evolved from fighting against the sea to living with it, and from controlling floods to making room for rivers, provides a valuable example.

In 2022, GCA will be scaling up its efforts to accelerate adaptation in deltas. In Bangladesh, GCA is preparing to work on urban and water resilience in the Bangladesh Delta.

GCA’s Water Adaptation Community recently launched a Community of Practice (CoP) on deltas. The World’s Deltas CoP is a platform for knowledge sharing and learning across different delta networks and initiatives worldwide, such as RAD and the Delta Alliance.

“With so many different delta initiatives, and the need to facilitate each of them, we need to be innovative and scale up our engagement with more partners. WAC will come in to, for example, be a platform to share experiences on how deltas around the world have dealt with or can deal with various issues, for example, subsidence,” said Ase Johannessen, GCA’s WAC Facilitator.

Pregnancy rate among women in Southern coastal belt lower: Ainun Nishat

publications

The pregnancy rate among women in Koyra in Khulna and Shyamnagar in Satkhira is much lower, while the Southern coastal region of the country has been witnessing negative population growth due to the adverse impact of climate change, said Professor Ainun Nishat, water resource and climate change specialist.

“Salinity is increasing in coastal areas while hypertension is on the rise among both males and females. Climate change is successively building at the adverse impacts. Female reproductive rate is under threat,” he said at a discussion on “Integrated Community Development for Better Health Outcomes: Perspectives from Bangladesh” organized by URC, an international organization based in the US at the Sheraton Dhaka Banani on Tuesday.

He said that in Satkhira, Khulna, Bagerhat and Barguna,  specially the southern thana’s population growth is negative, people are migrating. Bangladesh has suffered serious drought for the last two or three years, and crops are not harvesting in time.

“In Bangladesh, on the curative side, we have improved. We have lots of hospitals, lots of clinics, and some good doctors there. We need to pay attention to the curative side and public health activities as well,” said Ainun Nishat, also professor emeritus of Brac University.

The event highlighted promising interventions and good practices in health service delivery at the community level. Bangladesh has been a leader in public health research and implementation on a large scale for low-cost technologies provided at the community level

Conference moderator, Maureen Shauket, URC Chief Operating Officer, said: “New thinking and learning from the experiences of others is key to improving the quality of care and health outcomes in the communities where we work.”

IPCC Report: We can halve emissions by 2030, but the time for action is now

publications

We already have the tools and know-how required to limit warming and halve emissions by 2030, finds new IPCC report.

GENEVA, Apr 4 In 20102019 average annual global greenhouse gas emissions were at their
highest levels in human history, but the rate of growth has slowed. Without immediate and deep
emissions reductions across all sectors, limiting global warming to 1.5°C is beyond reach. However,
there is increasing evidence of climate action, said scientists in the latest Intergovernmental Panel
on Climate Change (IPCC) report released today.

Since 2010, there have been sustained decreases of up to 85% in the costs of solar and wind
energy, and batteries. An increasing range of policies and laws have enhanced energy efficiency,
reduced rates of deforestation and accelerated the deployment of renewable energy.


“We are at a crossroads.
The decisions we make now can secure a liveable future. We have the
tools and knowhow required to limit warming, said IPCC Chair Hoesung Lee. I am encouraged by
climate action being taken in many countries. There are policies, regulations and market
instruments that are proving effective. If these are scaled up and applied more widely and
equitably, they can support deep emissions reductions and stimulate innovation.”


The Summary for Policymakers of the IPCC Working Group III report, Climate Change 2022:
Mitigation of climate change was approved on April 4, 2022, by 195 member governments of the
IPCC, through a virtual approval session that started on March 21. It is the third installment of the
IPCC’s Sixth Assessment Report (AR6), which will be completed this year.

We have options in all sectors to at least halve emissions by 2030 Limiting global warming will require major transitions in the energy sector. This will involve a substantial reduction in fossil fuel use, widespread electrification, improved energy efficiency, and the use of alternative fuels (such as hydrogen).

Having the right policies, infrastructure, and technology in place to enable changes to our lifestyles
and behavior can result in a 4070% reduction in greenhouse gas emissions by 2050. This offers
significant untapped potential, said IPCC Working Group III CoChair Priyadarshi Shukla. “The
evidence also shows that these lifestyle changes can improve our health and wellbeing.

Cities and other urban areas also offer significant opportunities for emissions reductions. These can
be achieved through lower energy consumption (such as by creating compact, walkable cities),
electrification of transport in combination with lowemission energy sources, and enhanced carbon
uptake and storage using nature. There are options for established, rapidly growing, and new cities.

We see examples of zero energy or zerocarbon buildings in almost all climates, said IPCC
Working Group III CoChair Jim Skea. “Action in this decade is critical to capture the mitigation
potential of buildings.

Reducing emissions in the industry will involve using materials more efficiently, reusing and recycling
products, and minimizing waste. For basic materials, including steel, building materials, and
chemicals, low to zerogreenhouse gas production processes are at their pilot to nearcommercial
stage.


This sector accounts for about a quarter of global emissions. Achieving net-zero will be challenging
and will require new production processes, low and zero-emissions electricity, hydrogen, and, where
necessary, carbon capture and storage.


Agriculture, forestry, and other land use can provide largescale emissions reductions and also
remove and store carbon dioxide at scale. However, land cannot compensate for delayed emissions
reductions in other sectors. Response options can benefit biodiversity, help us adapt to climate
change, and secure livelihoods, food and water, and wood supplies.

The next few years are critical

In the scenarios we assessed, limiting warming to around 1.5°C (2.7°F) requires global greenhouse
gas emissions to peak before 2025 at the latest, and be reduced by 43% by 2030; at the same time,
methane would also need to be reduced by about a third. Even if we do this, it is almost inevitable
that we will temporarily exceed this temperature threshold but could return to below it by the end of
the century.


“It’s now or never if we want to limit global warming to 1.5°C (2.7°F), said Skea. “Without
immediate and deep emissions reductions across all sectors, it will be impossible.

The global temperature will stabilize when carbon dioxide emissions reach net zero. For 1.5°C
(2.7°F), this means achieving net-zero carbon dioxide emissions globally in the early 2050s; for 2°C
(3.6°F), it is in the early 2070s.


This assessment shows that limiting warming to around 2°C (3.6°F) still requires global greenhouse
gas emissions to peak before 2025 at the latest, and be reduced by a quarter by 2030.


Closing investment gaps


The report looks beyond technologies and demonstrates that while financial flows are a factor of
three to six times lower than levels needed by 2030 to limit warming to below 2°C (3.6°F), there is
sufficient global capital and liquidity to close investment gaps. However, it relies on clear signalling
from governments and the international community, including a stronger alignment of public sector
finance and policy.


Without taking into account the economic benefits of reduced adaptation costs or avoided climate
impacts, global Gross Domestic Product (GDP) would be just a few percentage points lower in 2050
if we take the actions necessary to limit warming to 2°C (3.6°F) or below, compared to maintaining
current policies” said Shukla.


Achieving the Sustainable Development Goals


Accelerated and equitable climate action in mitigating and adapting to climate change impacts is
critical to sustainable development. Some response options can absorb and store carbon and, at
the same time, help communities limit the impacts associated with climate change. For example, in
cities, networks of parks and open spaces, wetlands, and urban agriculture can reduce flood risk and
reduce heatisland effects.


Mitigation in the industry can reduce environmental impacts and increase employment and business
opportunities. Electrification with renewables and shifts in public transport can enhance health,
employment, and equity

 

Climate change is the result of more than a century of unsustainable energy and land use, lifestyles
, and patterns of consumption and production, said Skea. This report shows how taking action now
can move us towards a fairer, more sustainable world.
