COP30 highlights urgent need for accelerated global action and finance to meet Paris targets

Ten years after the landmark Paris Agreement at COP21, the global community finds itself at a pivotal juncture as COP30 concludes in Belém, Brazil, a city situated at the gateway to the Amazon rainforest, one of Earth’s most vital natural ecosystems imperilled by climate change. The urgent message from COP30 echoes the reality that despite a decade of policy efforts, the world remains significantly off track to limit warming to the Paris target of 1.5°C.

According to the latest United Nations Emissions Gap Report, current policies set the world on a path to approximately 2.8°C of warming by century’s end, a level that carries severe risks for natural and human systems worldwide. While sceptics question the value of the Paris Agreement, analysis from Climate Action Tracker indicates it may have successfully curtailed global warming projections by about 1°C compared to pre-Paris forecasts. This reduction is substantial, given the exponential risks and costs associated with every incremental degree of warming.

However, the challenge ahead is formidable. Industrial sectors remain stubbornly difficult to decarbonise. Heavy industries such as steel, cement, and chemicals rely heavily on fossil fuels and high-temperature processes not yet economically replaceable by electricity or cleaner alternatives. Industry electrification is projected to increase modestly from 22% in 2021 to only 31% by 2050 under current trends, underscoring the technological and economic hurdles ahead. Oxford Economics highlights that accelerating industrial decarbonisation demands enhanced policy support, including higher carbon pricing, competitive renewable electricity costs, and targeted incentives for emerging technologies like green hydrogen and plasma burners.

Beyond industrial emissions, the imperative intensifies for advanced economies to bolster the low-carbon transitions of emerging markets and developing economies (EMDEs). These regions are forecast to contribute the majority of 21st-century emissions, making early support vital to avoiding cumulative emissions that could push temperatures further beyond safe limits. The principle of common but differentiated responsibility, enshrined in the UN Framework Convention on Climate Change (UNFCCC), has led to financial commitments such as the USD 100 billion annual climate finance target set at COP15 in Copenhagen, with a revised goal of USD 300 billion by 2035 agreed at COP29.

Yet, experts argue this funding remains insufficient, particularly for Africa, where climate needs outpace available resources. Ensuring adequate and timely climate finance will be essential to enabling EMDEs to adopt technologies and policies aligned with net zero pathways. Brazil’s hosting of COP30 brought with it the announcement of the ‘Baku to Belém Roadmap,’ a plan aiming to scale global climate finance to $1.3 trillion annually by 2025. This initiative focuses on increasing grant funding, easing private capital access for developing nations, and encouraging multilateral financial institutions to assume greater risk and alleviate debt burdens. Nevertheless, political disagreements and the need for stronger leadership from wealthier nations remain significant obstacles.

Alongside these policy and finance initiatives, COP30 also emphasised the interlinkages between climate and health. A high-level event co-organised by the World Health Organization and United Nations University spotlighted climate justice and the health co-benefits of climate action. The event showcased progress toward climate-resilient and sustainable low-carbon health systems, recognising that addressing climate change presents opportunities to improve public health outcomes globally.

Despite the lofty ambitions, practical challenges persist. Infrastructure in Belém, including facilities intended to accommodate world leaders and delegates, faced construction delays just weeks before COP30’s start. However, local authorities assured that over 30 public works projects were on track, reflecting the complexity and urgency of hosting a global gathering within a fragile and strategically important ecological region.

Crucially, the United Nations Environment Programme warned that the planet is set to breach the 1.5°C warming threshold within the next decade if current emissions trajectories continue. Achieving the 55% reduction in greenhouse gas emissions by 2035 required to stay below this limit appears increasingly unlikely without intensified global action.

Looking forward, the next phase of climate action will shift from pledges to implementation, reshaping markets, investment flows, and competitive dynamics, especially for businesses engaged in industrial decarbonisation. Oxford Economics highlights the critical need for business leaders to anticipate policy shifts and quantify their exposure to evolving regulatory and market landscapes, positioning themselves advantageously amid the accelerating low-carbon transition.

COP30, therefore, marks both a reckoning and an opportunity. It underscores the necessity of advancing industrial decarbonisation technologies, scaling climate finance especially for developing economies, integrating health considerations into climate policy, and accelerating global collective action to move decisively toward net zero. The coming years will test the global community’s resolve to uphold the Paris Agreement’s promise against the backdrop of an increasingly volatile climate future.
