Paris Agreement and  COVID19

Paris Agreement, The epidemic and measures to contain it have resulted in significant cutbacks in worldwide economic activity and associated fossil energy use, with unknown implications for long-term efforts to restrict greenhouse gas emissions under the Paris Climate Agreement.

To investigate this effect, projections of economic recession and recovery in recent months are expanded to include a return to full employment in future years, and then compared to a growth estimate if COVID-19 had not occurred.

On the assumption that the Paris emissions goals for 2020 will be met in any case, projections of world emissions with and without the pandemic reveal that it will have only a minor influence on emissions in 2030 and beyond through its growth impact alone.

Other COVID legacies could include lingering effects on consumption and travel habits, as well as the allocation of recovery monies to low-carbon investments. The impact of economic shocks on countries’ willingness to meet (or increase) their existing Paris emissions goals will be the most critical factor. The main effect of the pandemic on the threat of climate change will thus be its influence on national promises to action, rather than its impact on GDP.

The pandemic will have long-term consequences for society, the economy, and the environment, with one key legacy being its impact on the worldwide effort to reduce human-induced climate change. The 2015 Paris Climate Agreement and the emission reduction pledges made by countries under its rules and processes are currently the focus of that effort.

Nationally Determined Contributions, or NDCs, are targets for reducing emissions that must be met by most countries by 2030. The Agreement calls for a five-year update of promises, therefore at the fall 2020 conference of its parties, the parties were to provide the results of a review of their initial NDCs in the hopes of increasing ambition. The first effect of the epidemic has been the postponement of this crucial phase in the Paris process until fall 2021.

One of COVID-19’s consequences is obvious. The rest of its consequences are highly speculative. Apart from efforts prompted by Paris targets, the current global recession and the rate of recovery over months and years will have an impact on all nations’ emissions-producing activities.

Furthermore, the experience of social estrangement and business closure will leave a record of changes in demand patterns and corresponding energy use. The likelihood of further waves of infection, which would cause further economic devastation, adds to the uncertainties. These consequences will have an impact on national plans to satisfy current NDCs and raise ambition in 2021.

The pandemic’s effect on overall economic activity

By contrasting our prior study of pre-pandemic growth forecasts with one that attempts to account for the recession and predicted recovery, we may get a sense of the pandemic’s impact on economic activity alone. Of course, both of these economic futures are unclear, so predicting the recession’s final severity and recovery route requires extra caution. Still, by extending evaluations of COVID-19’s near-future influence to later years, we can investigate its implications.

We’ll start with the Congressional Budget Office’s estimate of a 5.6 percent drop in GDP in 2020 and a +4.2 percent rise in 2021, as well as the accompanying unemployment rate (U.S. Congressional Budget Office, 2020a).

Despite the turbulence of the situation, the CBO’s September update of 5.9 and +4.8 percent is not significantly different (U.S. Congressional Budget Office, 2020b). This expected recovery in 2021 still leaves economic activity lower than it was at the end of 2019, and without the pandemic recession, the US economy could have risen by another 4% to 5% in these two years.

Employment has increased as a result of efforts to reopen the economy in the second and third quarters of 2020, but the increase in subsequent quarters is projected to be modest. As a result, the CBO projects that employment will be more than 6% below “full” employment by the end of 2021. (i.e., the employment rate at the end of 2019).

We estimate the path by which the economy might return to full employment over the long run, with its accompanying GDP and energy implications, assuming this estimate of the initial shock.

To estimate the likely employment effects and repercussions for GDP, energy use, and emissions, we regress an asymptotic function on these CBO estimates (employment = a + b (1/t)+ error), where “t” is the quarter of year numbered sequentially. This formula generates an asymptote of 97.5, which is less than 100.

We model that employment pattern through 2030, with a restoration to full employment beginning in 2035. Because of fewer savings and investment during the recession, the economic repercussions last longer.

This is a skewed extrapolation of one possible path of the pandemic’s initial economic impact and recovery. Much will be determined by the virus’s progress and the rate at which vaccines are developed and used, with expectations fluctuating month to month. The success of additional budgetary measures aimed at limiting the expenses of the downturn will also have an impact on the recovery in the United States.

It’s an issue that has caught the attention of the Chairman of the Federal Reserve in the United States, who stated, “Too little support would lead to a weak recovery… Insolvencies among households and businesses would soar, putting the economy’s productive potential at risk (Powell, 2020).

At the very least, the expectation that employment consequences will last a decade or more is consistent with the apparent employment repercussions of financial crises like the one in 2008. Many jobs will be lost, learning new skills takes time, and incomes and productivity may never recover to pre-crisis levels, even if workers return to work.

We employed the economic model we used in our pre-pandemic assessment of the global emissions trajectory to simulate this shock to total productivity. The resulting GDP impact for the United States in 2020 is similar to the CBO’s forecast. Then, in order to calculate the worldwide impact, we assume that the pandemic causes the same overall productivity shock everywhere else, with GDP impacts lasting until 2030.

Various forecasts for other parts of the world have shown a nearly universal reduction in GDP relative to pre-pandemic levels across key countries and regions (Fitch Ratings, 2020; World Bank Group, 2020). Our procedure’s outcomes. demonstrate how COVID-19 decreases world GDP by 2035.

It is 8.2 percent lower in 2020, which is the total of a 5.1 percent loss compared to end-2019 and 3.1 percent of predicted global growth in 2020 that does not occur. By 2035, GDP will be within 2% of where it would have been had the epidemic not occurred.

The World Bank Group’s assessment of the global shock, which displays a core estimate of a 5.2 percent decline in 2020 but includes projections of 2020 GDP reductions ranging from near 3 percent to over 9 percent, demonstrates the uncertainty in these calculations .

To study the impact of the growth shock on carbon emissions, we assume that nations will stick to their Paris commitments despite the disruption, and that the structure of their economies will not be significantly altered as a result of the experience. The impact of decreased GDP on emissions, comparing the combined effect of Paris pledges and the COVID-19 recession to emissions under Paris alone.

Global emissions are down by 3.4 percent in 2020 as a result of the pandemic and country measures to mitigate its consequences, and they are still down by roughly 2 percent in 2025. Only 1% of annual emissions have been cut by 2030. (The effect is even smaller in 2035, but the projection does not take into account the new round of NDCs due in 2025, which will cover the years after 2030.)

Because most emissions goals under the Paris Agreement remain intact for most regions, the effect on 2030 emissions is minor. Lower future GDP does not modify the aim, and so has no effect until the recession drives emissions below the pledged level, as is the case for countries whose goal is set relative to a historical emission level.

Countries with objectives based on a business-as-usual future may now have a lower BAU, necessitating a lower absolute reduction in emissions to satisfy the Paris pledge. However, because a country’s BAU estimate is often submitted with its NDC, there will be no effect on emissions unless it is actually amended in response to COVID-19.

On the other hand, emission objectives of regions with intensity targets (ton CO2 per dollar of GDP) are impacted, and those (mostly China) are the reason why, by 2030, emissions, including the recession, will be below the Paris target. Without the Paris targets in place, emissions are expected to fall 7.4% in 2020, 4.4 and 4.2 percent in 2025 and 2030, respectively, as a result of reduced GDP due to the pandamic.

Of course, the human input of greenhouse gases to the environment continues during and after the epidemic, albeit at a little less destructive pace for a few years.

Another structural changes that may affect greenhouse gas emissions

nothing else is possible COVID-19 legacy is a shift in economic structure that isn’t captured by economic assessments based on historical data, such as ours. The future of the transportation sector, which is a major source of greenhouse gas emissions, is a hot topic. Businesses and their employees have learnt a lot about the cost and effectiveness of various methods and different styles of working from home.

Additionally, a lingering dread of congestion may have a long-term impact on air travel and urban rapid transit. The interruption of supply chains during the pandemic could cause countries to take steps that restrict international goods commerce, which is less apparent but potentially substantial.Increased usage of virtual shopping, banking, and entertainment could hasten changes in the service sector, with fewer “brick and mortar” businesses (and lower energy use) but perhaps greater transportation emissions from delivery services.

In our prediction, total private vehicle emissions account for only 612 percent of world emissions in 2030, with air travel accounting for 3%. At the most optimistic scenario for emissions, if private car use remained 10 to 30% below pre-COVID-19 levels, world emissions would drop by 0.6 to 2%, and if air travel remained 50% below, global emissions would drop by another 1.5 percent.

Reduced inclination to commute in congested public transportation, as well as more delivery services as a result of increasing virtual purchasing, would result in higher emissions elsewhere in transportation. A trend toward shorter supply chains could go the other way, making it difficult to predict the influence on other modes of transportation. A shift to more virtual commerce might lower the requirement for commercial floor space and air conditioning—a 10 to 20% reduction would appear to be significant, but it would only reduce world emissions by 14 to 12 percent.

In the end, these diverse consequences are indistinguishable. The impact on economic structure and energy consumption, as well as likely additional factors not yet recognized, will influence emission reduction plans and nations’ willingness to make more ambitious pledges under the Paris Agreement. To appropriately guide national climate policy decisions, this pandemic’s legacy must be understood to the extent possible, given existing uncertainty. Nonetheless, according on the facts known to date, the most significant climatic consequence of COVID-19 is its influence on national commitment to action, not the short-term reduction in greenhouse gas emissions.
