Introduction
In 2025, the urgency around net-zero emissions has moved from a boardroom buzzword to a bottom-line priority. Achieving net-zero means balancing the greenhouse gases released into the atmosphere with those removed. As climate science advances, our understanding of what net-zero truly involves continues to evolve. Net-zero emissions refer to reducing all greenhouse gas emissions as much as possible and balancing the remainder with permanent removals such as carbon capture, reforestation, or soil sequestration. This approach is holistic and aligned with scientific recommendations.
In contrast, carbon neutral typically refers to offsetting emissions—often focusing only on carbon dioxide—by funding equivalent CO₂ savings elsewhere, without necessarily reducing emissions at the source. Climate positive goes a step further by removing more carbon than is emitted, an ambitious goal that is becoming a new benchmark for sustainability leaders.
The urgency of net-zero efforts is underscored by the fact that global average temperatures have already increased by over 1.1°C compared to pre-industrial levels, leading to record-breaking wildfires, heatwaves, and floods. According to the IPCC’s 2023 report, global emissions must be reduced by 43% by 2030 to keep the 1.5°C target within reach, making net-zero commitments more critical than ever (Source: IPCC).
Why Carbon Emissions Are Still Rising
Global carbon emissions keep rising due to ongoing dependence on fossil fuels and challenges in implementing effective climate policies. Many countries struggle to translate net-zero pledges into concrete actions, resulting in continued emissions across major sectors.
This persistent rise in emissions threatens public health, accelerates biodiversity loss, and creates economic disruptions through damaged infrastructure and strained food and supply systems (Source: Wikipedia).
A Quick Look at Major Emission Sources Globally
According to the IEA's Global Energy Review 2025, energy-related CO₂ emissions continued to rise in 2024, albeit at a slower pace compared to 2023. The primary contributors to this increase were fossil fuels, with natural gas emissions rising by approximately 2.5% (180 Mt CO₂), coal emissions increasing by about 0.9% (135 Mt CO₂), and oil-related emissions growing by 0.3%.
While the IEA does not provide a detailed sector-by-sector breakdown in the 2025 report, historical data and previous reports offer insights into the distribution of global GHG emissions:
Energy Sector (Electricity and Heat Production): Approximately 25% of global GHG emissions
Industry: Around 24% of global emissions.
Agriculture, Forestry, and Other Land Use (AFOLU): About 24% of global emissions.
Transportation: Approximately 15% of global emissions.
Buildings: Around 6% of global emissions.
The Gap Between Climate Pledges and Real-World Action
Over 140 countries have announced net-zero targets, covering around 88% of global greenhouse gas emissions. However, the Net Zero Tracker highlights a critical gap: only a small fraction of these targets are supported by legally binding commitments to phase out fossil fuels. For instance, just 7% of global emissions are covered by national commitments to phase out coal, oil, or gas production and use.
This gap between ambitious pledges and concrete, enforceable policies poses significant risks. Without clear, enforceable interim milestones, carbon-intensive activities may continue under the guise of future promises, jeopardizing the goals of net-zero.
Impacts on Health, Ecosystems, and the Global Economy
The rising carbon emissions are not just an environmental issue—they have wide-reaching effects on public health, ecosystems, and the global economy. These impacts are already being felt around the world and are expected to intensify without urgent action.
