When representatives from nearly 200 countries finalized the Paris climate agreement on Dec. 12, 2015, there were celebrations around the world. But it has now been five years and the world is in a state of deepening uncertainty. The coronavirus disease pandemic has ushered in deepening economic and social crises, as well as a wave of increased indebtedness. The geopolitical landscape is as fractured as it has been in decades and, with global supply chains being reorganized, the prospects for achieving deeper integration through trade are fading. Yet, despite all the recent turmoil, one certainty remains: The climate crisis and the need to stick with the Paris accord, which is the only roadmap that we have for decarbonizing the global economy. Though the agreement initially met with doubts, its primary mechanisms are proving their efficiency and efficacy, and its target of reaching net-zero greenhouse gas emissions by mid-century is now the point of reference for governments and businesses around the world. A growing number of economic sectors — public and private finance, energy, transport and, increasingly, industry — are setting targets consistent with this objective. With the 2021 UN Climate Change Conference (COP26) approaching, the immediate task for governments is to strengthen their climate plans (following the logic of the Paris agreement’s “ratchet mechanism”) to lock in emissions-reduction targets for 2030. Politically, the world has reached a tipping point. Donald Trump’s infamous June 2017 Rose Garden speech announcing America’s withdrawal from the Paris agreement set off a negative domino effect, encouraging Brazil, Australia and Mexico to also temper their climate ambitions. But we are now on the cusp of a positive domino effect, as more governments and sectors realize that decarbonization is the key to future economic competitiveness. In 2020, ambitious new net-zero commitments by China, Japan, South Korea and the EU were followed by Joe Biden’s election to the US presidency, together marking a decisive shift in the global calculus. In 2021, the G7 and the G20 could both make climate policymaking (not least green finance) the central issue on the global agenda. A majority of members in each group have already established net-zero targets, and thus will need to increase their 2030 benchmarks accordingly. The EU, for example, will need to reduce net emissions by 55 percent by 2030 in order to meet its 2050 goal. Beyond the latest developments in the US, the EU and China, broader economic trends and the mobilization of non-state actors have lent further momentum to climate action. Since 2015, there has been a 22,000 percent increase in assets committed to fossil-fuel divestments, and many large multinational companies have committed to emissions reductions in line with the Paris agreement. For example, in late 2020, Malaysia’s state energy giant Petronas joined BP, Shell and Equinor in setting a 2050 net-zero emissions target, while Spain’s Iberdrola, the world’s third-largest utility, announced that it will invest €75 billion ($90 billion) over the next five years to double its renewable energy capacity. Meanwhile, Volkswagen’s CEO has acknowledged that the company’s survival depends on its ability to pivot to electric vehicle production, starting with a €33 billion investment between now and 2024. We are on the cusp of a positive domino effect, as more governments and sectors realize that decarbonization is the key to future economic competitiveness.

These efforts are all underpinned by strong grassroots support for climate action. Even amid a pandemic, polls show that people are as concerned as ever about climate change and want their governments to do more to protect the planet. These pressures are creating a virtuous circle. Far from being just words on paper, net-zero commitments are having a significant effect on the real economy. A major trade deal between the EU and Mercosur (Argentina, Brazil, Paraguay and Uruguay), for example, has been blocked by a number of EU member states over concerns about Brazilian President Jair Bolsonaro’s disregard for environmental protections and issues like deforestation. As a result, many Brazilian businesses — including in the beef and soy industries — have been pressuring the Bolsonaro government to change course. Moreover, in pursuing the European Green Deal, the EU is considering a carbon border adjustment mechanism to put a carbon price on certain imports from outside the bloc. The mechanism will be developed through close engagement with trade partners and could be the beginning of a new era of cooperation, as other countries committed to net-zero targets will have to push their own industries to pursue decarbonization. Still, we cannot be blindly optimistic. The fact is that we are running out of time. We know that 2010-20 was the hottest period on record and that the atmospheric concentrations of greenhouse gases have continued to rise fast. We know that emissions from fossil fuels and forest fires reached an all-time high in 2019 and we are now regularly confronted with images of melting glaciers, burning rainforests, streets choked with smog, and small islands battered by superstorms. Even in regions or countries where emissions have peaked, the effort to get to net zero by 2050 will need to be stepped up threefold. Other regions, meanwhile, are not even close to meeting the challenge. With entire economies and societies changing fast, this is the moment for political leadership to push things across the finish line. The new Biden administration will play a critical part in the global response, but the US alone will not solve the problem. In these times of increasingly distributed global leadership, we must all work together. The international community’s next milestones — at the G7, the G20, and COP26 — will be decisive. This is a game of dominoes that we can win. • Laurence Tubiana, a former French ambassador to the United Nations Framework Convention on Climate Change, is CEO of the European Climate Foundation and a professor at Sciences Po, Paris.
