As the world burns, literally and figuratively, a pressing question dominates the minds of climate activists, policymakers, and concerned citizens: have international climate treaties moved the needle in the right direction? The Paris Agreement, signed in 2015 by almost 200 countries, marked a historic moment in the global fight against climate change. Its goal of limiting global warming to well below 2°C, and pursuing efforts to limit it to 1.5°C above pre-industrial levels, was a beacon of hope for a sustainable future. But, five years later, have these agreements yielded tangible progress, or are we still stuck in the slow lane?

The short answer is that progress has been made, but it’s far from satisfactory. The Paris Agreement has galvanized a global dialogue on climate action, with countries committing to Nationally Determined Contributions (NDCs) outlining their plans to reduce greenhouse gas emissions. However, a closer look at the numbers reveals a more nuanced picture. According to the United Nations Environment Programme (UNEP), in 2020, global emissions were only 0.5% lower than in 2010, and the world is still on track to overshoot the 1.5°C target by a significant margin.
So, what’s going wrong? One major issue is the lack of ambition in NDCs. While countries have pledged to reduce their emissions, these targets are often not stringent enough to meet the Paris Agreement’s goals. In fact, a study by the Climate Action Tracker found that, based on current NDCs, the world is likely to warm by 3.2°C by 2100. Another challenge is the lack of enforcement mechanisms to ensure countries meet their commitments. The Paris Agreement relies on voluntary reporting and peer review, which can be time-consuming and ineffective in holding countries accountable.
Despite these challenges, there are glimmers of hope. The European Union, for example, has set a bold target of becoming carbon neutral by 2050, and its member states are making significant progress in reducing their emissions. Other countries, like Costa Rica and Rwanda, have implemented innovative policies to promote renewable energy and sustainable land use. Additionally, the growth of renewable energy sources, such as solar and wind power, is accelerating, with costs decreasing dramatically over the past decade.
To accelerate progress, some experts advocate for more stringent international targets, such as a global carbon price or a system of tradable emissions permits. Others suggest that climate action should be integrated into broader economic and development strategies, rather than being treated as a separate issue. Whatever the solution, it’s clear that the clock is ticking. The Intergovernmental Panel on Climate Change (IPCC) warns that, to limit warming to 1.5°C, global emissions must be cut by 45% by 2030 and reach net-zero by 2050.
In conclusion, while international climate treaties have made progress, the pace of change remains too slow. The world needs to pick up the pace, and fast. Can we still turn the tide on climate change? The answer depends on our collective willingness to take bold action, to set ambitious targets, and to hold ourselves and others accountable. The clock is ticking, and it’s time to make some real noise.
