The Paris Agreement and its swift entry into force represent a bold statement of the determination of the international community under the United Nations to transform the global economy so as to limit the impact that our power generation, production methods, agriculture, and consumption patterns have on the climate system.
The Agreement is in itself a global strategy for the longer term that is defined by the three aims enshrined in its Article:. These three aims provide a single and clear direction of travel to state and nonstate actors for the longer term, given the link between economic activity, greenhouse gas emissions, and the impacts of climate change. According to the latest available science, achieving the long-term temperature goal would require global greenhouse gas emissions to peak by and subsequently be reduced to zero before the end of the century.
To limit warming to 1. The temperature goal reflects, above all, a vision of the type of society we want for the future. It represents an aim to design our economic system so that improving our quality of life is not hindered by the negative impacts on our climate.
In the light of science, this vision implies a major transformation. It compels us to rethink the way we produce, use, and consume energy; how we manufacture and build; and how we manage our land and ecosystems.
If global net greenhouse gas emissions are to reach zero at some point before the end of this century, we need to ensure that our energy and production systems become neutral in terms of greenhouse gas emissions so that there is at least a balance between human-generated greenhouse gas emissions and removals of emissions from our land and through healthy, natural ecosystems.
This transformation must be achieved over time but also in time. No single country has the capacity to decisively shift the global energy base or land use patterns on its own.

What is the Paris Agreement? A simple guide to climate change. What was agreed? Every five years, each country is expected to submit an updated national climate action plan - known as Nationally Determined Contribution , or NDC.
In their NDCs, countries communicate actions they will take to reduce their greenhouse gas emissions in order to reach the goals of the Paris Agreement. Countries also communicate in the NDCs actions they will take to build resilience to adapt to the impacts of rising temperatures. To better frame the efforts towards the long-term goal, the Paris Agreement invites countries to formulate and submit long-term strategies.
Unlike NDCs, they are not mandatory. In terms of employment, the clean energy sector employed more than 3 million Americans before the start of the COVID pandemic—about 14 times the number of coal, gas, oil, and other fossil fuel industry workers—and has the potential to employ many more with further investments in energy efficiency, renewable energy, and electric grid modernization to replace the aging coal-powered infrastructure.
But supporting policies that promote an equitable transition —with community-led decision-making, a focus on equity, and retraining support—is an important means to helping communities leave the dirty energy economy behind them. Finally, rather than giving China and India a pass to pollute, as Trump claimed , the pact represents the first time those two major developing economies have agreed to concrete and time-bound climate commitments.
Both countries, which are already poised to lead the world in renewable energy, have made significant progress to meet their Paris goals. The Paris Agreement is the culmination of decades of international efforts to combat climate change. Here is a brief history. In , President George H. The pact set no limits on greenhouse gas emissions for individual countries and contained no enforcement mechanisms, but instead established a framework for international negotiations of future agreements, or protocols, to set binding emissions targets.
Participating countries meet annually at a Conference of the Parties COP to assess their progress and continue talks on how to best tackle climate change. The Kyoto Protocol , a landmark environmental treaty that was adopted in at the COP 3 in Japan, represents the first time nations agreed to legally mandated, country-specific emissions reduction targets.
Bush argued that the deal would hurt the U. That year, at the COP 18 in Doha, Qatar , delegates agreed to extend the accord until without some developed nations, which had dropped out. They also reaffirmed their pledge from the COP 17 in Durban, South Africa, to create a new, comprehensive climate treaty by that would require all big emitters not included in the Kyoto Protocol—such as China, India, and the United States—to reduce their greenhouse gas emissions.
The new treaty—what would become the Paris Agreement—was to fully replace the Kyoto Protocol by However, the Paris accord went into effect earlier than expected, in November While the Kyoto Protocol and Paris Agreement both set out to address climate change, there are some key differences between them.
Unlike the Kyoto Protocol, which established top-down legally binding emissions reduction targets as well as penalties for noncompliance for developed nations only, the Paris Agreement requires that all countries—rich, poor, developed, and developing—do their part and slash greenhouse gas emissions. To that end, greater flexibility and national ownership is built into the Paris Agreement: No language is included about the commitments countries should make; nations can set their own emissions targets NDCs consistent with their level of development and technological advancement.

Meanwhile, despite temporary emissions drops related to changes in production and travel associated with the COVID pandemic, current evaluations of how countries are performing in the context of their Paris climate goals indicate some nations are already falling short of their commitments. The heavy lifting—reining in emissions even further by and —still needs to be done, and the accord provides the tools and pressure to make that happen.
As the Paris Agreement matures, nations including the United States must firmly commit to phasing out fossil fuel investment locally and abroad and investing in nature-based solutions. Often, the communities who contribute least to global emissions are the ones already showing wealthier nations the way , committing to rapid emissions reductions, renewable energy expansion, protecting their forests, and putting economies on low-carbon pathways.
Nations must uplift these communities as well as those who are faced with the brunt of climate impacts. This includes formally protecting Indigenous knowledge and right s , which are critical to fighting the climate crisis. Even without stronger recognition within the Paris Agreement, Indigenous and frontline communities are building a global movement and successfully fighting back against extractive, climate-damaging industries, including fossil-fuel pipelines , logging , dams , and mining.
In fact, the mobilization of support for climate action across the country and around the world provides hope that the Paris Agreement marked a turning point in the global race against climate change.
We can all contribute to the cause by seeking opportunities to slash global warming contributions—at the individual , local , and national levels—but we understand better than ever that individual action is not enough. There is a lot of damage from the Trump administration that President Biden will need to undo—and quickly.
But the effort will be well worth the reward of a safer, cleaner world for future generations. The next Conference of the Parties is currently scheduled for November in Glasgow. The aims of COP 26 will be to assess the progress made under the Paris Agreement and to encourage countries to enhance their original NDCs into greater alignment with current climate science.
