A
s the world marks the midpoint of the pivotal decade for delivering on the Paris Agreement and the Sustainable Development Goals (SDGs), climate action efforts find themselves at a critical crossroads. The year 2024 represents both a litmus test on the international community’s willingness to take bold steps as well as an inflection point for recalibrating woefully inadequate progress to avert the most catastrophic climate change scenarios.
This year’s spate of deadly wildfires, megadroughts, crop failures, extreme heat waves, and destructive flooding across every inhabited continent has been a visceral reminder that planetary warming is unfolding faster than expected. The latest reports from the Intergovernmental Panel on Climate Change (IPCC) underscore the harrowing impacts already materialising while reiterating the narrow window remaining to radically transform systems and behaviour.
Yet even amidst these alarm bells, this year’s data reveals a shocking dearth of substantive climate action aligning with the increasingly urgent scientific evidence. Commitments and finance flows from national governments, businesses, and regional stakeholders continue trailing far behind the scale required for keeping global temperature rise below the 1.5°C ceiling targeted under Paris. Measuring progress against key 2024 benchmarks illustrates the chasm between rhetoric and reality on climate.
NDCs & Global Emissions Trajectory
Under the Paris Agreement’s bottom-up architecture, countries’ voluntary Nationally Determined Contributions (NDCs) form the backbone of global climate mitigation efforts. However, the latest aggregate analysis from the UNFCCC, UNEP, and Climate Action Tracker reveals national climate plans submitted as of 2024 put the world on a devastating path exceeding 2.8°C of warming by century’s end.
Moreover, several major emitters including Australia, Brazil, Indonesia, Russia, and Saudi Arabia have either failed to update NDCs with enhanced ambition or set woefully inadequate targets incompatible with 1.5°C pathways. In total, national commitments from four-fifths of countries assessed are currently rated as either “highly insufficient” or just slightly better at “insufficient.”
The few bright spots of climate leadership regrettably pale in comparison. Only a handful of countries including Norway, Switzerland, the United Kingdom, and Morocco have established ambitious economy-wide net zero emissions goals by 2050, backed by detailed plans consistent with the Paris Agreement’s temperature limits.
“While it’s encouraging to see this vanguard of climate leadership, their mitigation efforts alone represent just a fraction of the needed emissions reductions,” said Dr. Tosi Mpanu-Mpanu, UNEP’s 2024 Emissions Gap Report lead author. “To get the world on track for 1.5°C, NDCs from top emitters like China, India, the United States, and those still missing in action must quickly ratchet up with aggressive short-term cuts approaching 50% over this decade.”
SDG 13 Progress: Climate Finance Shortfalls and Resiliency Gaps
The United Nations’ SDG 13 on Climate Action features targets related to strengthening adaptive capacity and resilience while mobilising climate finance from developed to developing nations. However, progress has persistently lagged behind stated ambitions and targets.
Data from the OECD indicates climate finance from developed countries totaled just $58 billion in fiscal 2023, well short of the $100 billion commitment first pledged for 2020. Contributions earmarked for adaptation measures assisting front-line communities averaged under 30% of the total. Moreover, multilateral development banks, the private sector, and specialised climate funds like the GCF and GEF have fallen far short of mobilising the broader $1 trillion in public and private capital annually estimated for facilitating an orderly transition across the developing world.
The impacts of these finance shortfalls are increasingly clear. The latest UN assessments show 3.6 billion people currently enduring acute vulnerabilities like water scarcity, food insecurity, displacement and exposure to climate-driven natural disasters. While adaptation plans have been initiated across 158 countries, implementation progress remains obstructed by inadequate capacity, monitoring, and resource mobilisation.
New York is just one of countless cities worldwide struggling to adapt critical infrastructure to anticipated sea level rise and intensifying storm systems. The city’s recently unveiled “NYC Climate Adaptation Roadmap” calls for investing over $25 billion for coastal defences and stormwater management upgrades through the 2050s. But securing the estimated $4 billion in annual funding required remains daunting.
Expanding Horizons: New Models for Mitigation, Resiliency, and Climate Finance
Despite these stark climate action realities, myriad pioneering initiatives and innovations across all spheres of society offer pragmatic pathways to accelerate implementation and impact. Innovative models from governments, businesses, investors, and climate entrepreneurs could catalyse the necessary transitions in the coming years.
Carbon Pricing and Emissions Trading
As countries like Canada, Singapore, and members of the EU Emissions Trading Scheme have demonstrated, carbon pricing mechanisms can drive market-based emissions reductions while raising public funds for mitigation and adaptation initiatives. China’s national emissions trading system, due for full implementation by 2025, could prove a pivotal carbon pricing model for incentivizing industrial-scale abatement across the world’s largest current emitter.
Sector-specific programs like the UN’s ICAO CORSIA for aviation and IMO’s carbon pricing and efficiency standards for global shipping are also achieving measurable emissions cuts. Complementary initiatives scaling voluntary carbon markets like the Taskforce for Scaling Voluntary Carbon Markets (TSVCM) and Climate Finance Partnership offer entities additional options to purchase high-integrity offsets abating emissions. These systems collectively generated over $1 billion in 2023 reinvested into climate finance, clean energy projects, and nature-based solutions like reforestation.
Climate Tech & Resilient Infrastructure
Emerging technologies pioneered by climate tech startups and scaleups are also beginning to be deployed at wider scales for mitigation, resiliency, and adaptation. Smart grid innovations like Virtual Power Plants and Internet of Things technologies have been implemented across multiple US states and European municipalities, enabling more seamless integration of renewable energy while reducing household emissions 20-30%.
Firms like PostScripts, Terramera, and Pivot Bio are commercialising bio-based crop protection products helping agriculture boost climate resilience while regenerative aquaculture solutions from Ando and XetaWave enable low-emission protein production. Early-stage ventures like NASA spin-off Air Company are even developing carbon capture technologies converting captured CO2 into vodka, hand sanitizers, and other consumer products.
Sustainable Urban Infrastructure and Finance Models
Recognizing the frontline threats cities face, ushering more localised resilience planning, financing, and infrastructure development is paramount. While larger metropolises like Miami and New York have detailed adaptation roadmaps, many municipalities struggle to prioritise and fund infrastructure upgrades against competing priorities.
To help address this funding challenge, emerging finance models like resilience bonds, climate resilience funds, and partnerships like UNCDF’s Municipal Investment Fund are creating new asset classes tapping private capital for adaptation at the city level. Pooled resilience funds invest in multiple regions while resilience bonds securitize resilient infrastructure investments, enabling municipalities to raise capital for specific localised interventions.
Carbon Removal and Nature-Based Solutions
Land sector activities and agriculture alone contribute over one-third of annual greenhouse gas emissions. However, innovations in carbon removal and nature-based solutions offer holistic opportunities for climate action while providing co-benefits around biodiversity, food security, and community resilience.
Through initiatives like Reducing Emissions from Deforestation and Degradation (REDD+), indigenous and pastoral communities are increasingly stewards protecting vital carbon sink ecosystems like tropical rainforests and peatlands. Engineered solutions like Microsoft’s recent investment into Planetary, a direct air capture startup, signal private sector buy-in for nascent carbon removal technologies. Meanwhile, carbon trading programs pioneered by Nori and Lyme enable farmers and landowners to earn carbon credits for adopting regenerative agriculture practices capturing atmospheric CO2.
Accelerating Climate Impact: New Metrics for Guiding Ambition
While innovations abound, tracking the cumulative impact and effectiveness of these solutions remains challenging given insufficient monitoring systems, fragmented reporting, and inconsistent methodologies. Catalysing the transformative progress required over this final stretch of the 2020s necessitates embracing more holistic, consistent metrics integrating all dimensions of climate action.
The UN’s systemwide engagement in the CAMRI (Climate Action Monitoring, Reporting and Verification Instrument) aims to facilitate harmonised reporting standards, leveraging machine learning and satellite monitoring to transparently track national- and sub-national mitigation efforts, finance flows, and resilience-building progress against stated commitments like NDCs and NAPs in near real-time.
Simultaneously, partnerships such as the Global Climate Indicators Platform initiated by Yale’s DataDriven EnviroLab and ODI are compiling location-specific datasets tracking physical climate risks, exposures, and adaptive capacity gaps across SIDS, LDCs, and major population centres. Having both action-tracking and risk/vulnerability metrics displayed together could empower more granular prioritisation and local climate planning.
On the mitigation front, initiatives like the Science-Based Targets Initiative (SBTi) and the Greenhouse Gas Protocol offer established methodologies for enterprises to robustly measure emissions footprints and align reduction targets with climate science. Harmonising these benchmark frameworks across sectors and industries with climate finance taxonomies being pioneered by the EU and the Climate Finance Leadership Initiative could further mainstream impact accounting.
While measurement remains an outstanding hurdle, applying smarter metrics and transparent reporting against them could be transformative. Clearly quantifying countries’/entities’ concrete actions, financing commitments, and measurable outcomes would drive accountability – enabling policymakers, investors, and citizens to make informed decisions prioritising effective interventions. Public “climate risk and progress scorecards” updated dynamically across regions and sectors could be a powerful mechanism catalysing a climate ambition loop.
2024: A Pivotal Year on the Path to Climate Sustainability
As this 2024 snapshot reveals, the current state of climate action is one of contrasts and contradictions. Breakthrough commitments from government, business, and finance leaders are catalysing promising innovations across domains like pricing carbon, resilient infrastructure, and emissions removal.
Yet even these bright spots pale against the collective tide of missed targets, inadequate ambition, and finance deficits dramatically outpaced by climate hazards already ravaging communities worldwide. The window for catalysing the systemic changes required for attaining the Paris Agreement’s temperature ceiling is rapidly closing.
Maintaining the status quo, with its piecemeal portfolio of disjointed initiatives, will not suffice. Bending the curve on emissions and vulnerabilities demands greater coordination, more widespread policy restructuring, accelerated finance mobilisation at scale, and transparency to guide decision-making. Above all, delivering real climate progress necessitates enhancing accountability around measurable targets backed by pragmatic actions.
As the world navigates this pivotal year, addressing long standing gaps through revitalised multilateralism, de-risking climate investments in innovation ecosystems, and elevating communities on the frontlines as stakeholders must be priorities. By doubling down with the requisite ambition and focus, we can honour already-overdue commitments, align efforts with scientific urgency, and catalyse the climate revolution still within our grasp before it’s too late.
The stakes for success could not be higher – preserving a habitable, equitable planet for generations to come. While the path forward is steep, the untapped potential of human ingenuity, resources, and global partnership offers hope for steering all nations towards our collective climate endgame.
