All nations worldwide were tasked this year with providing updated strategies to combat climate change. However, the submitted plans have had minimal impact on reducing the future warming of Earth, according to a recent United Nations report. The withdrawal of the United States from these efforts has also offset a significant portion of the progress made.
The latest climate plans, required every five years under the 2015 Paris Agreement, are projected to reduce future warming by approximately 0.3 degrees Celsius compared to previous estimates. Only one-third of the countries that are part of the agreement, representing 63% of emissions, have submitted new climate plans.
Canada submitted its most recent plan in February, which has been deemed “highly insufficient” by the Climate Action Tracker group. Despite setting targets for emissions reduction, Canada is forecasted to fall short of its goals for both 2030 and 2035.
A recent report by the Institut de l’énergie Trottier at Polytechnique Montreal calls for a coordinated policy reset to transition to a net-zero energy system. While Canada has established a sound process for setting targets and plans, there is a need for more comprehensive follow-through on these commitments.
In contrast, the Trump administration’s policies in the U.S., such as rolling back environmental regulations and impeding green energy projects, are predicted to contribute an additional 0.1 degrees Celsius of warming, as highlighted in the UN Environment Program’s Emissions Gap report.
The emission of greenhouse gases like carbon dioxide, primarily from the combustion of fossil fuels, is the main driver of global temperature increase. The current policies are projected to lead to a warming of 2.8 degrees Celsius, emphasizing the importance of the upcoming UN climate talks in Belem, Brazil.
Despite efforts to reduce emissions, global temperatures are still expected to rise by at least 1.7 degrees Celsius this century. The UNEP executive director stressed the need for accelerated action to address climate change.
The United States, which previously pledged significant emissions cuts but is now set to exit the Paris Agreement, plays a crucial role in determining future emissions levels. The rest of the world must offset the projected increase in American carbon pollution by cutting an additional two billion tonnes of carbon dioxide annually.
The report underscores the urgency for world leaders to take decisive action to curb emissions and mitigate the impacts of climate change. Ambitious climate actions not only address environmental concerns but also bring economic benefits and enhance public health. The upcoming UN climate talks are seen as a crucial opportunity for global climate action.
